PS1 Sinewave Interactive Inverter Charger
1 Precautions and Safety
1.1 Multiple Hazardous Energy Sources
Hazardous voltages and energy are generated by the PS1, are fed into the PS1 by external wiring from
multiple sources, and may be stored in capacitors after the PS1 is switched off and disconnected from
external wiring.
Do not operate with the door open. No operating procedures in this manual require the PS1 door to be
opened. All PS1 operations are performed with the door closed. This includes the front panel operation of
all PS1 pushbuttons, displays and circuit breakers.
Only suitably qualified and trained personnel should open the PS1 front door.
Installation procedures in this Technical Manual require the PS1 front door to be opened to access internal
wiring terminals and connectors. All commissioning and test procedures are performed with the door closed
except where explicitly stated in this manual.
1.2 Heavy
The PS1 is heavy (up to 98kg). Take care when lifting and moving the PS1. Use appropriate mechanical
lifting aids to move the PS1. Four eye bolts (provided) can be screwed into the top of the PS1 cabinet for
attaching a lifting harness.
1.3 Installation
The PS1 requires adequate ventilation, away from hot equipment. Do not obstruct the airflow through the
ventilation holes in the PS1 case (sides, rear and door top). Ensure when installed in an enclosed space
that there is adequate ventilation.
The PS1 must be located in a dry place away from water, electrolyte and corrosive aerosols.
The PS1 contains arcing contacts so must not be located where explosive gas mixtures could occur, such
as hydrogen from batteries or diesel fuel fumes. The PS1 must never be installed above the battery bank.
1.4 Maintenance
Ensure that all energy sources are isolated before working on connected wiring. The generator may start or
power may be restored by the inverter at any time
Never work on equipment or investigate a problem without following appropriate safety isolation procedures.
Procedures are defined in the PS1 Technical Manual.
1.5 Inverter or Generator may Start Automatically
The PS1 automatically starts and/or restarts and may restore power or start the generator at any time.
If a fault or overload is detected the PS1 will shutdown and automatically attempt to restart at varying
intervals of up to several hours.
1.6 Battery
Batteries are very dangerous. Please read the safety information provided by the battery supplier.
Battery acid is dangerous.
Batteries can emit hydrogen gas, which is explosive.
Batteries connected in series can produce hazardous voltages.

Technical Manual
PS1 Sinewave Interactive Inverter Charger
Disconnecting a DC power connection (even on one battery cell) can cause dangerous high-energy DC
arcs, which can cause serious burns and eject hot particles, and can be difficult to extinguish.
Disconnecting a DC power connection (even on one battery cell) can cause renewable sources to produce
large voltages (much larger than the battery voltage) on battery terminals and DC wiring. Such voltages can
be lethal. They can also damage the PS1. Only suitably trained and qualified personnel should disconnect
any DC power connection, including battery cell connections, and only with suitable procedures and safety
precautions.
1.7 Generator
Please read the safety information provided by the generator supplier.
The generator produces hazardous voltages.
The generator installation should follow relevant standards and practices for the installation of fuel storage,
for ventilation and dispersal of exhaust gas. Exhaust gas in enclosed spaces can kill.
The generator installation should include a means of isolating the generator automatic control inputs from
the PS1. The generator must be isolated from the PS1 during servicing.
The PS1 automatically starts and/or restarts and may restore power or start the generator at any time.
Never work on equipment or investigate a problem without following appropriate safety isolation procedures,
including turning off isolating switches and disconnecting the generator start battery.
1.8 Renewable Sources
Please read the safety information provided by the supplier.
Renewable sources can produce hazardous voltages.
Shorting or disconnecting renewable wiring which is energized or carrying current can produce dangerous
DC power arcs which are difficult to extinguish.

2 Site Selection
The inverter performance rating is dependent on the environmental operating conditions, in particular
ambient temperature and ventilation. There are also safety considerations that must be addressed.
Appropriate site selection and preparation are fundamental to getting the optimum performance from the
PS1.
The site should be selected and prepared to provide:
•
A dedicated lockable power room/area for PS1 and associated equipment.
•
No access to unauthorized personnel or children.
•
Maintenance of the ambient temperature within the product specification (see Appendix A).
•
Adequate ventilation, away from hot equipment. Ensure unobstructed airflow through the
ventilation holes in the inverter case (sides and door top). See A.9 Mechanical Details for air flow.

•
A dry location away from water, condensation, electrolyte and corrosive aerosols.
•
A location free from the risk of explosive gas mixtures occurring, such as hydrogen from batteries
or diesel fuel fumes. The inverter contains arcing contacts which may ignite such mixtures. Never
mount the PS1 above batteries.
•
Rodent proof.
•
A mounting surface and method suitable for the inverter weight with adequate safety margin (see
Appendix A.1 Product Specifications for unit weight). If the inverter is wall mounted the mounting
method must be in accordance with the installation instructions using the fasteners specified.
•
Sufficient space available in front of the inverter to open the inverter door and work on the inverter
internals.
Following the guidelines below will help maintain the system reliability and maximise the life of the PS1,
generator and other components.
•
Reduce operating temperatures. All equipment will provide longer and more reliable service if
protected from high temperatures and regular wide temperature variations. PS1 power capacity is
reduced when operating in high ambient temperatures.
•
In hot areas a shed or room with a shade roof above and on walls exposed to direct sunlight and
with reasonable ventilation will reduce maximum temperatures.
•
In areas with wide temperature variation between day and night, insulate the building and fit
ventilation controlled by internal room temperature to dispose of excess heat.
•
Install the generator in an area with good ventilation and well separated from the PS1 and the
batteries. Do not allow heat or exhaust from the generator to heat the PS1, the battery or other
equipment.

•
Follow the instructions for routine monitoring and maintenance.
•
Monitor the performance of the system by periodically reviewing the PS1 logged data. The logged
data may indicate the system is not performing optimally and system settings changes or some
maintenance may be required. A telephone line and a modem connected to the PS1 will allow the
logged data and settings to be reviewed remotely.

3 PS1 Wiring
The electrical wiring recommendations herein apply to Australia and New Zealand, and are based on
standard AS4509 – Standalone Power Systems.
The PS1 has been designed to comply with AS/NZS 3100 - General Requirements for Electrical Equipment
and as such can be installed into a system and be compliant with AS/NZS 3000 - Electrical installations as
required by AS4509.
For other regions, the installation and wiring should comply with relevant national standards and practices.
3.1 External Wiring Schematic
Figure 1 is a typical schematic of wiring connected to the inverter via the site switchboard. This wiring
scheme facilitates inverter bypass and also isolation of the inverter, generator and loads at one location.
Note: This schematic is intended to guide the designers of systems using the inverters. Do NOT use this
typical schematic to trace actual site wiring, which may differ in detail from that shown below.

3.2 DC Power Wiring
The following sections refer to the 3.1 External Wiring Schematic.
3.2.1
Fuses
The battery fuses shown (or circuit breakers if desired) are necessary to protect the DC wiring. The fuses
should be rated to handle the maximum current flow during normal operation. The renewable fuses should
be rated to protect the wiring from back feed from the battery. The fuse ratings should be coordinated with
conductor sizes and temperature ratings.
For recommended fuse sizes refer to §A.8 Battery Fuse Recommendation.
It must not be possible to supply renewable power to the inverter with the battery disconnected, since the
inverter can be damaged by uncontrolled sources which are not voltage-limited by the battery. Therefore the
renewable and battery fuses should be “ganged” together in one physical assembly to ensure they are all
removed together.
The removable ganged fuse assembly also allows isolation of the renewable source, the battery and the
inverter from each other before working on them.
To prevent dangerous DC arcs, it must be possible to ensure that negligible DC current is made or broken
when connecting or disconnecting any DC Power Wiring. For example before working on the battery wiring,
the inverter is switched off via its On/Off button, the renewable regulator is switched off, and the battery is
isolated from the renewable source and from the inverter by removing the ganged fuse assembly.

Technical Manual
3.2.2
PS1 Sinewave Interactive Inverter Charger
DC Cables
The high current wiring within the battery stack, and between the battery and the inverter, should be as direct
as possible, with the positive and negative cables bundled close together. This minimizes the wiring
inductance which assists the overall efficiency of the inverter system.
For recommended battery cable sizes refer to A.6 Battery Cable Recommendation.
The DC terminals for battery and shunt connection are M8 studs. Suitable lugs must be used for connection
to these studs.
Similarly the high current wiring between the battery and the renewable regulator, and between the regulator
and the renewable array, should be bundled and as direct as possible.
The DC cabling should be kept separated from the AC cabling.
3.2.3
DC Earth and Lightning Protection
The system earthing strategy for lightning protection will depend on specific site characteristics hence is left
to the judgement of the system designer/installer. The standard AS/NZS 1768 – Lightning Protection
provides details of lightning protection schemes.
To reduce the risk of accidental short circuits, earthing the DC Power Wiring is not recommended. If the
lightning protection scheme calls for the earthing of the DC wiring, the DC earth conductors must be
separate the AC Earth system and the DC Earth cables must be capable of caring the battery fault current
and blow the fuse before the earth cabling fails due to the fault current.
The control electronics are wired to battery negative.
3.3 AC Power Wiring
The following sections refer to the 3.1 External Wiring Schematic.
3.3.1
Circuit Breakers
The circuit breakers in the PS1 are designed to protect the wiring inside the PS1 and under normal operating
conditions, including faults on sub circuits will not normally trip. External AC wiring must be protected with
suitably rated external circuit breakers.
3.3.2
Residual Current Device
The Residual Current Device (RCD) installed in the AC Switchboard as shown protects the AC Load circuits
ONLY. A fault in the inverter and/or the generator cabling is not RCD protected and hence will not trip the
device RCD.
3.3.3
AC Cables
AC cabling must be sized appropriately for the application.
AC cabling should be kept separated from the DC cabling.
3.3.4
AC Generator Connection
The generator should be hard wired into the inverter system.
If the generator is to be plugged into the system, if disconnected while synchronised, voltage from the
inverter may be present on the plug. In this arrangement the requirements of AS4509.1 must be adhered to.
3.3.5
Earthing
It is recommended the inverter be earthed to its own earth stake adjacent to the inverter, and also to the
switchboard. Ensure the earth cable is suitable to carry the fault current and not fail before the circuit
breakers trip. Using the same size conductors as the AC cables ensures the earth wiring will carry the fault
current.
High Earth Leakage Current. Unit must be earthed before connecting to supply or operating unit.
Do not use the protective earth terminal for battery earthing.

Labelling
Multiple power sources (inverter and generator) which may start or re-start at any time provide power to the
AC Switchboard. It is recommended that a warning label be fitted to all electrical power terminations at each
location and to isolators feeding the location, together with a basic electrical diagram indicating the power
sources and isolators.
Suggested warning label:
Multiple Hazardous Energy Sources
Ensure that all energy sources are isolated before working on connected wiring.
Inverter or Generator may Start Automatically
The generator may start or power may be restored by the inverter at any time.
A sheet of labels with the above text is provided with each PS1.
3.4 External Alarm Wiring
The external alarm is provided by an isolated NO/NC (normally open or normally closed) relay contact. This
relay contact is NOT fused. Any external wiring connected to this contact must be fused to protect the wiring
and relay contact.
See A.4 Alarm Interface Specification for contact ratings.
An alarm condition is indicated with the coil being de-energised. With the inverter in the Off state, the
external alarm should be active.
The following is an example showing how a light could be connected to the alarm relay.

Wiring Diagrams
There are many different generator controllers and generator start/stop control schemes. The PS1
generator controller has been designed to interoperate with as many different types of controller as possible.
Depending on the type of controller these wiring diagrams will need to be adapted to suit the particular
controller.
All diagrams include a Generator Available control switch. This switch should be located as close as
practicable to the generator. This switch is used to prevent the PS1 automatically starting the generator
whilst being serviced. When in the open state (as shown) the PS1 will indicate that the generator is not
available and will not attempt to automatically start the generator.
The diagrams also include information regarding other control inputs to the PS1. They are shown separately
on each diagram for clarity only – they may be used together or in any combination.

Wiring Diagrams
The diagrams are indicative only. Each site will have differing requirements and these diagrams will need to
be adapted to suit the required configuration.
The PS1 provides one internal shunt connected between the Renewable Negative and Battery Negative
terminals as shown in Figure 8.
3.6.1.1
Renewable Only – Shunt 1
The following diagram shows a basic configuration with the renewable connected and monitored by Shunt 1.
The regulator output and the battery are connected in parallel, via the PS1 Shunt 1 which is to be used to
measure the renewable current. The Shunt settings do not need to be changed as this is the default
configuration.

Shunt Inputs
The shunt monitoring is provided by two high impedance differential inputs – Shunt 1 and Shunt 2. These
inputs are NOT fused. Any external wiring connected to these inputs must be fused or limited by other
means to protect the wiring and shunt input.
See A.5 Shunt Interface Specification for input ratings.
The internal 100A/50mV shunt is factory connected to the Shunt 1 input. This may be disconnected and
used to monitor an external shunt as required.
Both Shunt 1 and Shunt 2 can be wired and configured to monitor a renewable source, a DC load or both
simultaneously resulting in a net current reading. See §6.5 Shunt Settings for details of configuration
options.

4 Installation
PS1 installation should be performed only by suitably trained and qualified personnel.
Ensure that the installation site is in accordance with 2 Site Selection.
4.1 Inspection
Before shipment the PS1 was rigorously tested and dispatched in perfect working order. Due to the freight
distances and handling involved, the inverter should be inspected as follows before installing it or connecting
power to it:
1. Inspect packaging for signs of damage.
2. Remove packaging from unit and examine the inverter case and ensure there are no obvious signs
of damage.
3. Remove the PS1 from the shipping pallet by removing the two (2) bolts underneath the pallet.
4. Inspect the top of the pallet and the underneath of the PS1 and ensure there are no obvious signs
of damage.
5. With a suitable screwdriver unscrew the two front door retaining screws and open the door, to view
the various Printed Circuit Board Assemblies (PCA), interconnecting cables and connectors. See
7.1 Inverter Internal View.
6. Check all cable connectors to ensure they are properly seated in their sockets. Avoid pulling on the
cables or straining their connections. Note: Three pin cable under Power PCA is not connected.
7. Visually check all connections to circuit breakers and contactors.
8. If all connections are sound and there are no signs of damage to the inverter cabinet, proceed with
installation. If there are problems, please contact the inverter distributor.
Please retain the inverter packing material for use if the inverter needs to be shipped.
4.2 Mounting
The PS1 can be shelf or wall mounted. One half of the wall mounting bracket is pre assembled to the PS1.
This may be removed if not required.
The mounting position must ensure an adequate airflow. A minimum clearance of 150mm must be provided
adjacent to the ventilation inlet and outlet areas (see Appendix A.9 Mechanical Details for ventilation area
details).
The shipping pallet must not be used for mounting the PS1.
All wiring to the PS1 must pass through the inverter bottom. Ensure the mounting position allows for all of
the required cabling, taking note of the minimum bend radius of heavy DC wiring.
The PS1 is heavy. Ensure appropriate lifting techniques and mechanical lifting aids are used when moving
and mounting the PS1. Four eye bolts (provided) can be screwed into the top of the PS1 cabinet for
attaching a lifting harness. Unscrew and remove the four M4 hex bolts and the fibre washers from the top of
the cabinet and retain. Screw the four eye bolts with the fibre washers into position. The eye bolts should
be removed and the hex bolts replaced when the mounting has been completed.
4.2.1
Shelf Mounting
For shelf-mounting, the inverter can simply sit on the shelf, or can optionally be bolted to the shelf via M8
bolts up into the inverters rubber feet. See A.9 Mechanical Details for feet locations. It is recommended that
the PS1 be bolted into position.
The shelf must allow for the wiring beneath the inverter.

Wall Mounting – Hanging Bracket
The wall mount position must be on a concrete or masonry wall using at least five (5) 8mm bolt diameter
Dynabolt sleeved anchors or equivalent of suitable length for the wall material, evenly spaced and fitted
according to manufacturer’s instructions.
Wall-mounting procedure:
•
The cabinet mounting bracket and two rubber bumpers are attached to the rear of the PS1 during
manufacture. Verify all bracket mounting bolts are tight.
•
Mount the Rear Hanging Bracket. Use the bracket as a template, with the bracket horizontal, mark
the hole positions on the wall. At least five evenly spaced mounting holes must be used.
• Install the anchors as per the anchor manufacturer’s recommendation.
•
Raise the PS1 and lower it onto the hanging bracket ensuring the location slots in the cabinet
mounting bracket mate with the hanging bracket location tongues.
•
Rest the lower portion of the PS1 against the wall on the two rubber buffers.

4.3 Additional Componentry
If any additional components are to be installed into the PS1 cabinet, they may be installed onto the raised
DIN rail. Take care to ensure that any disturbed internal wiring is re-connected to the same location.
Special attention is drawn to the small EMI leads fitted into the top of the AC and DC circuit breakers and
into the top of the neutral terminal.
DO NOT DRILL into the internal chassis of the PS1. The primary transformer is located directly behind the
chassis. The un-used pressed inserts in the chassis may be used to mount additional components. Use the
shortest possible (6mm) M4 Zinc Plated Steel screws.
Ensure that hazardous voltages cannot contact with the chassis or any other wiring. Check the clearance of
additional components to ensure the door will close correctly.
DO NOT utilise the chassis earth screw and stud points for any mounting or additional earth wiring.
4.4 Wiring
This section provides information regarding the wiring of the PS1 only.
Ensure all wiring is de-energised when making connections to the PS1. Ensure other power sources cannot
automatically start and energise wiring.
All wiring feeds up through the bottom of the PS1. A gland plate and cable gland nuts are provided for the
installation of all cable. Any unused cable cut-outs should be fitted with gland plugs to keep out vermin.
Suitable grommet edging material should be fitted to protect the wiring from sharp edges.
See Appendix A.9 Mechanical Details for cut-out details.
Wiring locations referred to in the following sections are indicated in Figure 11 DC and AC Wiring Locations
and Figure 12 Control Wiring Locations below. The same labels are also on the inside door of the PS1.

Figure 12 Control Wiring Locations
4.4.1
DC Wiring
DC wiring should be fed up through the appropriate cut out and terminated to the PS1. Ensure the
protective plastic cover remains in place after connecting DC cables.
Connect the lugged battery negative lead to the inverters Battery Negative terminal under the load washer
ensuring the face of the lug is directly against the PS1 contact surface. Tighten the nut with a calibrated
torque wrench to 8 Nm.
If required, similarly connect the renewable negative lead to the inverters Shunt 1 Negative terminal.
Similarly connect the battery positive lead to the inverters Battery Positive terminal.
4.4.2
Battery Temperature Sensor
A battery temperature sensor is supplied pre-wired within the inverter. Pass the sensor and its wiring out
through the inverter bottom cut-out, and mount the sensor in thermal contact with the centre of the side of a
battery. It is good practice to insulate the sensor from the ambient air by covering the sensor when mounted
to the battery with insulating material.
If the sensor cabling is not long enough, disconnect the sensor wiring from J8 on the termination PCB and
add the additional cable. Ensure to insulate the joins.
The sensor is polarity sensitive – ensure that the correct polarity is maintained.
4.4.3
Shunt Monitoring
The sense wires for the externals shunts should be fed up through the appropriate cut out and terminated to
the PS1. The sense cabling should be kept as short as possible. “CAT5” type cabling or any multi
conductor multi strand cable is suitable for shunt sense wiring. Remember that these small cables are
connected to battery negative and an inadvertent short circuit with either lead to battery positive would short
circuit the battery bank. It is recommended that both these wires be separately fused.
The polarity of these shunt leads is not important if the shunt is to be used for either a renewable input or a
DC load. The shunt settings compensate for the direction of current flow. If the shunt will be used to
measure the Net between renewable and load then the polarity is very important. Ensure the positive shunt
connection goes to the positive shunt sense and that the current is flowing in the correct direction.
See 6.5 Shunt Settings.

Earth Wiring
Earth the inverter by connecting earth wiring from the switchboard earth stake to the inverter earth stake,
and from the inverter earth stake to the inverter Earth terminal.
4.4.5
AC Wiring
AC wiring should be fed up through the appropriate cut out and terminated to the PS1. Ensure the
protective plastic cover over the DC connections remains in place.
Connect the AC load wiring to the PS1: earth to either earth terminal, neutral to either neutral terminal, and
active to the Load Circuit Breaker.
Connect the AC generator wiring to the PS1: earth to either earth terminal, neutral to either neutral terminal,
and active to the Generator Circuit Breaker.
4.4.6
Generator Control
Generator control wiring should be fed up through the appropriate cut-out and terminated to the PS1.
“CAT5” type cabling or any multi conductor multi strand cable is suitable for all control wiring. The green
screw terminals can be plugged in and out of the termination PCA for ease of wiring.
Check what the generator controller requires to start and stop the generator and what type of outputs it
provides. See A.3 Generator Control Interface Specification.
4.4.6.1
Minimum Control Wiring
The generator run output must be connected so the PS1 can signal the generator to start and stop.
The generator available input should be fitted to indicate the generator is available to be automatically
started. If not fitted, the generator available override in the software must be set to ALWAYS. See 6.3
Generator settings.
Without the generator available installed, ensure that the PS1 start signal does not start the generator when
working on or servicing the generator.
4.4.7
External Alarm
Connect the External Alarm wiring to the inverter. “CAT5” type cabling or any multi conductor multi strand
cable is suitable. The green screw terminals can be plugged in and out of the termination PCA for ease of
wiring. Ensure appropriate fuses are fitted to protect the wiring and relay.
The alarm should activate since the inverter is presently out of service.
4.4.8
Serial Port cable
The serial port cable should be connected into J16 on the Control PCA (see Figure 14 Behind Front Door)
and fed out through an appropriate cut-out. This allows for connection to the internal serial port without the
need for opening the PS1 front door. This cable can be left unconnected if not required. The serial port is
isolated from the PS1 and no hazardous voltages are present on the interface cable.
When installed check that the cable does not foul on any internal cables or components.

5 Commissioning
This procedure is for the test and commissioning of the PS1. It does not cover other components in the
system however many of the tests described may exercise those components.
5.1 Inspection
No power should be applied at this stage.
5.1.1
Wiring
All connected wiring should be checked and tested for continuity and short circuits.
Check that no wiring feeding through the bottom cut-out is pressing against any sharp edges.
Check that any removed screw terminal plugs from the Termination PCA have been re-connected, correctly
aligned and are pressed firmly home.
Ensure that the DC stud insulating cover is in place.
Check that the DC and AC wiring is separated as much as possible.
5.1.2
Polarity
Ensure battery polarity is correctly wired to the PS1.
Ensure Active and Neutral terminals are correctly connected.
5.2 Initial Power Up
Read and understand the procedure below before proceeding.
Ensure that all the inverters front panel DC and AC circuit breakers are open. Renewable inputs should not
be connected at this stage. Ensure that the connected generator is shutdown and cannot start.
5.2.1
Door Open
Hazardous voltages are generated by the inverter and may also be fed into the inverter by external wiring
from multiple sources. The hazardous voltages may be stored in capacitors after the inverter is switched off
and disconnected from external wiring. The procedures below are to be performed only by suitably qualified
and trained personnel, taking appropriate safety precautions.
The initial DC connection is performed with the door open. The inverter’s front panel DC Circuit Breaker
remains open during this step.
Apply DC power to the inverter wiring by closing the external ganged battery/renewable DC fuse assembly
(or circuit breakers if used) - a small spark may be observed. Stop immediately and investigate if any fuse
blows or circuit breaker trips.
Check the RED LEDs on the lower edge of the power board. See 7.1 Inverter Internal View
LED1 should be ON
LED2 should be OFF
If LED1 is off, either power is not connected to the unit or the DC is connected in the reverse polarity. DO
NOT proceed until this corrected.
If LED1 is flashing, the connected DC voltage is incorrect. This is sometimes due to the initial power
connection. Press the front panel ON/OFF button once to reset the unit. LED1 should now be ON. If LED
continues to flash check battery voltages.
5.2.2

5.3 Configuration
The PS1 is configured with default values for all settings; at least some of these are likely to be unsuitable for
your installation. Access the Installer menus via the front panel LCD and set up the system parameters to
suit the site requirements.
Importantly, before using the system, ensure that the settings for Batt Size Ah (6.2 Battery Settings) and
Gen:Max kW (6.3 Generator settings) are configured to suit the battery and generator size installed, and
that all battery charger settings (6.6 Charger Settings) are suitable for the battery type installed and conform
to the battery manufacturer’s recommendations.
If the Batt Size Ah setting is modified it is necessary to power cycle the PS1 for the correct SoC calculations
to be displayed.
The PS1 incorporates a number of other settings that effect the system operation. The following should be
considered when setting the system to suit the site requirements
•
SoC generator start levels and times - See 6.3 Generator settings
•
Load power generator start levels - See 6.3 Generator settings
•
Minimum generator run time – See User Manual
•
Frequency and voltage tolerance for generator input. Note: Some generators have low frequency
cut-outs; the Low Freq Tol must be set above these limits. When setting the voltage and frequency
limits, allowance must be made for the difference in frequency and/or voltage when the generator is
cold. The default low frequency tolerance is 48.0Hz. See 6.4 AC Output settings
5.4 AC Load
Ensure all circuits at the distribution board are open.
Close the AC Load circuit breaker on the inverter, while ensuring there is no change in inverter operation.

5.5 Generator Synchronisation and Stability
The objective of these tests is to set the highest Gen Type setting whilst still maintaining stable generator
operation. Generally, a generator will operate satisfactorily with the PS1 set to Gen Type 0, however
optimum generator performance (steady ramping to power and agile response to load change) may not be
achieved at this setting.
Stable generator operation is defined as when there is no oscillatory variation or “bouncing” in the generator
output. On abrupt changes in load, the generator may “bounce” briefly and then return to stable operation.
An easy way to detect “bouncing” is to look for flickering in a low wattage incandescent light globe connected
to the system.
This procedure should be carried out with the battery bank partially discharged to enable the largest battery
charge load to be applied to the generator. Ideally the inverter will be limiting on battery charge current with
battery voltage below the charge voltage.
5.5.1
Configuration
If a generator available control switch has been installed, then set it to the open position. See 3.5 Generator
Control Wiring. No other configuration of the generator control relays or inputs is required.
Set Gen Type to 0 (Default setting). See 6.3 Generator settings
Check the front panel LED indication Gen NOT available. This must be ON. By default with no generator
control wiring the indication is ON. If OFF, check generator available control switch (if installed) and Gen
Avail setting is “Follow I/P” (Default setting). See 6.3 Generator settings
Manually start the generator.
5.5.2
Test – Generator Synchronisation
Once the generator has started, close the generator circuit breaker.
The PS1 will attempt to synchronise and connect to the generator. The PS1 will display Manual Gen Start
when synchronised and the front panel LED indication “Inv – Sync” will be active.
If the generator voltage and/or frequency is out of range the Gen Freq Error or Gen Volt Error LED
indications will be active. If required, adjust 6.4 AC Output settings
5.5.3
Test – Generator Stability
The inverter will start to apply load to the generator by ramping up the charge power to the battery bank.
Check that the generator remains stable through this process.
If the generator is stable, close the AC Load circuit breaker and then switch various AC loads ON and back
OFF again. The AC loads will be firstly powered by the inverter and then transferred to the generator.
Check that the generator remains stable through this process.
If the generator is not stable on Gen Type 0 – See 9 Troubleshooting
button for one second. The PS1 will display Gen NOT Available then Manual
Press and hold the
Gen Stop. The PS1 will disconnect from the generator. Since the generator is still running, the PS1 will
however attempt to re-synchronise.
Open Generator circuit breaker.
If a Gen Type proves unstable, then there is no need in testing the remaining types. In this case, set the
Gen Type back to the previous setting.
To ensure the charging process is reset, it is necessary to wait at least two minutes between each test.
Repeat the steps 5.5.2 and 5.5.3 above with Gen Type set to 1, 2 and 3 to determine the most suitable
setting for the generator.
Once the correct setting has been achieved Manually shutdown the generator and open AC Load circuit breaker.

Default 10.0
Range 1.0 -> 30.0
Generators ratings are typically given in kVA at a particular power factor, typically 0.8. The
value entered must be in kilowatts – multiply the kVA rating by the given power factor to obtain
the kilowatt value to be entered.
The ambient operating temperature of the generator should be considered and factored into
when setting the maximum power limit.
The inverter will use this setting and the variation of generator output voltage and frequency
from nominal (240VAC, 50Hz) to estimate the amount of power available from the generator Gen:Avail kW. The PS1 will limit the power drawn by the inverter to Gen:Avail kW.
As the generator frequency and voltage vary above and below nominal, Gen:Avail kW will
adjust higher and lower accordingly.
At nominal, the Gen:Max kW equals the Gen:Avail kW

Figure 15 Inverter Block Diagram
The block diagram above shows the main components and a simplified view of the inverter wiring.
7.2.1
DC and AC Power Circuits
These circuits are shown in heavy lines in Figure 15 Inverter Block Diagram above.
While the battery is supplying the load, DC power from the battery flows via the DC Circuit Breaker into the
Power PCA (Printed Circuit Assembly) where a FET (Field Effect Transistor) bridge chops it at several kHz
and feeds it via a filter choke to the 50Hz transformer. The FETs are turned on and off by drive signals from
the microprocessor on the Control PCA via wiring loom LM1. The microprocessor software varies the
chopping duty cycle (on-off ratio) so the average voltage fed to the transformer is a 50Hz AC sine wave.
The transformer steps up this AC voltage to the required generator level, and isolates the battery/renewable
circuits from the AC circuits. The AC power is fed to the load via the AC Contactor and the Load Circuit
Breaker.
AC power from the generator connects to the inverters Generator Active terminal. While the generator is
charging the battery, generator power flows into the inverter via the Generator Circuit Breaker, Generator
Contactor and AC Contactor through the 50Hz transformer into the Power PCA where the FET bridge
rectifies it to DC to charge the battery via the DC Circuit Breaker. The software varies the FET drive signals
to control the DC output voltage and current. The generator can supply the load via the Generator Circuit
Breaker, AC Contactor and Load Circuit Breaker.
If the software stops, the FETs are not driven, so the inverter passes no power in either direction.

Document PC0009 Revision 04
Page 62 of 97
Technical Manual
PS1 Sinewave Interactive Inverter Charger
The AC circuits pass through two Current Transformers (CTs) on the Termination PCA, for current
measurement. Note that the direction of the wiring through the CTs is important for correct determination of
AC power flows by the software.
The DC Circuit Breaker incorporates over-current trip for fault protection and (except the 24volt model) a
device to prevent closure in case of battery under-voltage or reversed battery voltage. The Power PCA trips
this Circuit Breaker via loom LM7 to isolate or shut down the inverter in case of battery over-voltage. The
software trips this Circuit Breaker via a signal in loom LM1 in case of excessive battery discharge etc. The
Circuit Breaker trip coil is powered from battery DC.
The Generator Circuit Breaker and Load Circuit Breaker incorporate over-current trip for fault protection.
The Control PCA software controls the AC Contactor and Generator Contactor via signals in loom LM2 then
LM6. The AC Contactor coil is powered by DC fed from the Power PCA via looms LM1 and LM2. The
Generator Contactor coil is powered by generator voltage from loom LM9, and with the inverter switched off
is energized so the load can be supplied from the generator.
While the generator is disconnected or not running, generator voltage is absent so the Generator Contactor
cannot close, thus inverter AC output voltage cannot become connected to the generator. If generator
outage occurs while the inverter is already connected to the generator, the inverter software automatically
detects the outage (due to power flow into the generator for example) and disconnects the generator by
opening the Generator Contactor.
7.2.2
Inverter Management
The Control PCA manages the inverter. It contains a microprocessor which runs the inverter software,
memory chips (which contain the software and logged data), and the inverter time/date chip. The Control
PCA also incorporates the front panel LCD display and buttons, and a serial port for connection of inverter
remote management via modem etc (see User Manual for details).
Via loom LM2 to the Termination PCA the software;
controls;
•
the AC Contactor and Generator Contactor.
•
the inverter cooling fans, running them only when needed. The fans are AC powered via loom LM3
from the Generator Contactor.
•
the inverter external alarm and generator control outputs.
and monitors;
•
AC currents from the two Current Transformers (CTs) on the Termination PCA.
•
AC generator voltage and frequency from a Voltage Transformer (VT) on the Termination PCA, fed
via loom LM9 from the Generator Contactor.
•
the transformer AC voltage and temperature, from the transformer assembly via the sensor wiring
(part of the transformer assembly).
•
the inverter internal air temperature, from a sensor mounted on the sensor wiring connector at the
Termination PCA.
•
the battery temperature from a sensor mounted on the battery.
•
the generator control input signals and Remote Run switch.
The software monitors DC voltage and current from the Power PCA via signals in loom LM17.
From the measured voltages and currents, the software calculates other values such as AC power flows and
battery ampere-hours. Based on such measured and calculated values, the software controls the contactors
and adjusts the FET bridge drive signals as required to control inverter synchronisation to the generator,
battery charging and AC supply to the load. The software displays important measured and calculated
values on the LCD display and records them in the data logging.
The software watches for unacceptable values, and takes appropriate action. For example it shuts down the
inverter for battery under-voltage or excessive inverter temperature, restarts the inverter when the condition
recovers, and displays the condition on the front panel LED indicators.

Document PC0009 Revision 04
Page 63 of 97
Technical Manual
PS1 Sinewave Interactive Inverter Charger
During inverter start-up self-test, the software similarly monitors inverter internal fault conditions such as FET
drive or bridge malfunction, aborts start-up if necessary, and displays the fault condition on the front panel.
7.2.3
Power to the Inverter Electronics
The inverter internal electronics power supplies are derived on the Power PCA from the battery DC, then
flow via loom LM1 to the Control PCA, then via loom LM2 to the Termination PC. To initially power the
electronics before the DC Circuit Breaker is closed, power is obtained from the EMC PCA (unswitched B+)
and loom LM7 to the Power PCA.
The inverter will not run if the battery is disconnected or the battery voltage becomes too low. Before the
inverter will run, the batteries will need to be replaced or charged for example from renewable power.
7.2.4
Electromagnetic Interference (EMI) Filtering
The DC and AC power circuits are connected to the EMC PCA which snubs (absorbs) surges and filters
EMI to prevent interference with other electronic equipment.
EMI is also filtered by various ferrite cores, chokes and capacitors in the wiring looms and the transformer
assembly.

8 PS1 Operation
The following section describes in detail the operation of the PS1. A good understanding of the operation of
the unit is not necessary but by knowing how the system works will enable you to understand the
programmed settings and change the user settings to suit your own needs as required.
The PS1 Battery management continuously monitors the system operation. This monitoring allows the PS1
to automatically start the generator to keep the battery system charged or if the load is sufficient, start to
supply the load directly. The monitoring includes any input from renewable sources and any loads directly
connected to the battery bank.
The PS1 uses a five stage temperature compensated battery charging system. This system gives a high
degree of flexibility so it can charge the multitude of battery types available.
The PS1 incorporates a programmable generator scheduler. These schedules can be set to meet regular
system loads. At a particular time the generator can be running ready to meet those loads which are better
powered directly from the generator.
Note: This section is a repeat of what is in the PS1 User Manual. It is included here for completeness.
8.1 Battery Management
Please refer to the battery manufacturer’s documentation for recommendations regarding settings for your
particular battery. Inappropriate settings may have a detrimental affect on your battery life and performance.
The PS1 provides comprehensive battery management settings and control to allow a charge regime to
achieve optimal battery life.
PS1 battery management features include:
•
State of Charge monitoring and control.
•
Battery voltage monitoring and control.
•
Charging initiated by battery state of charge and/or battery voltage.
•
Five stage charge cycle: Initial, Bulk (0-90%), Absorption (90%~100%), Float and Equalise.
•
Shutdown on very low battery voltage, battery state of charge, or both.
•
Battery Temperature compensation of charging voltage based on battery temperature.
The PS1 may be configured to automatically start the generator when a battery charge cycle is required.
It is important that the battery manufacturer’s recommendation be adhered to for ongoing monitoring and
maintenance of batteries.
8.1.1
Battery State of Charge (SoC) monitoring and control
The PS1 has no direct means of measuring the battery state of charge; it uses measurements of the
currents flowing in and out of the battery to estimate the charge remaining in the battery. The resultant net
current is expressed as a percentage of the battery size set in the PS1 (Batt Size Ah). There is no
compensation for the rate at which the current is drawn from or fed into the battery.
Current into the battery during a charge cycle and current measured on either of the shunts, when
configured as Renewable, add to the battery state of charge estimate.
Current out of the battery to supply the load and current measured on either of the shunts, when configured
as Load, deduct from the battery state of charge estimate.
If the shunt is configured as Renewable (+) and Load (--) the net result is added to the battery state of
charge estimate.
The state of charge is used to automatically start the generator and begin charging the batteries. Different
levels apply at different time of the days to ensure the generator is only used when required. Refer to 8.3.1
Generator Control based on SoC
© Selectronic Australia 2006
Document PC0009 Revision 04
Page 65 of 97
Technical Manual
PS1 Sinewave Interactive Inverter Charger
At completion of charge cycle the battery SoC based on the estimation will be close to 100% but may vary
depending of the charge and discharge rates.
8.1.2
Battery Voltage monitoring and control
The PS1 directly measures the battery voltage.
The battery voltage is used to automatically start the generator and begin charging the batteries. Normally
the battery voltage would not reach the levels set as the state of charge control levels would be reached first.
Different levels are used depending on the load on the system.
The battery voltage is used to protect the system by shutting the unit down should the battery voltage go
above or below set limits. The shutdown limits must be set to higher than the maximum charge voltage and
less than the generator start limits. For the low voltage shutdown limits the unit again employs different
levels depending on system load. The system will always attempt to start the generator before shutting the
unit down due to low voltage.
8.1.3
Battery Charger Operation
The PS1 charges the battery in a five-stage cycle with each stage controlled by voltage, current and time
settings. These settings are fully configurable in your unit however they should not require changing after
initial installation unless some aspect of the battery installation changes. The configured value of each
setting can be viewed on the LCD display (see User Manual for details ).
Each voltage setting is battery temperature compensated. The values displayed do not change. See
Battery Temperature.
Refer to the Battery Charging Cycle graph of the following page.
8.1.3.1
Initial
The PS1 charges at the initial charging current (Init:Chrg A) until the battery voltage rises to the initial
charge voltage (Init:Chrg V), holds this voltage for Init:Time mins, then starts the Bulk stage.
8.1.3.2
Bulk
The PS1 charges at the bulk charge current (Bulk:Chrg A) until the bulk charge voltage (Bulk:Chrg V)
is reached, then holds this voltage for at least Bulk:Time mins and until the battery is approaching a high
state of charge as indicated by the rate of change of charging current falling to Chrg:End A/15m. The
Absorption stage is then started.
8.1.3.3
Absorb
The PS1 charges at the absorb charge current (Absorb:Chrg A) until the absorb charge voltage
(Absorb:Chrg V ) is reached, then holds this voltage for at least Absorb:Time mins and until the
battery is approaching a high state of charge as indicated by the rate of change of charging current falling to
Chrg:End A/15m. At completion of this stage the charger will enter the Float stage unless a battery
Equalise cycle is due, in which case an Equalise cycle will complete before entering Float.
8.1.3.4
Float
The PS1 holds the battery voltage at the Float Hold V and will provide up to the absorb charge current to
maintain the Float Hold V. The charge current is limited to Absorb:Chrg A in this stage. The PS1 will
remain in this charge state until the generator has been shutdown.
8.1.3.5
Equalise
Periodically, as set by Eqlise:Freq Day, the PS1 performs an equalise charge in which the battery is
held at a higher voltage between Eqlise:Chrg V and Eqlise:Limit V for several hours
(Eqlise:Time hrs).
This restores to full charge any partially discharged cells in the series battery bank. To disable the Equalise
function Eqlise:Time hrs may be set to zero.
The Equalise cycle will be automatically delayed by one day for each day the battery has been in above the
Float:Hold V for the Float time set during installation.

PS1 Sinewave Interactive Inverter Charger
Battery Temperature
The PS1 monitors the battery temperature via the sensor provided. The supplied battery temperature
sensor is mounted in thermal contact with the centre of the side of a battery. If the sensor is not in thermal
contact with the battery bank the batteries will not be correctly charged.
The charge voltage set points are compensated by battery temperature. The compensation applied is -5mV/°C/cell with zero compensation at 20°C.
e.g. Init:Chrg V = 55.2, Battery Temperature = 26°C, No. Battery Cells = 24.
Compensated Charge voltage = 55.2 + ((20 - 26) x 0.005 x 24)
= 54.48
Absorb:Chrg V = 57.6, Battery Temperature = 6°C, No. Battery Cells = 24.
Compensated Charge voltage = 57.6 + ((20 - 6) x 0.005 x 24)
= 59.28
During all charge stages, the compensated charge voltage will not exceed Eqlise:Limit V.
Compensation improves battery performance and prevents battery overheating.
The charge current is also limited by battery temperature. Battery temperatures above 40°C cause the
battery charger to reduce the charge current limit point. This will help prevent battery overheating.
8.2 Renewable Management
The PS1 feeds renewable power to the AC load, and any excess is stored in the battery for later usage. If
the battery is fully charged and the DC load is not on, the excess is wasted (the renewable power is reduced
or disconnected by the regulator). Such waste can be reduced by reducing the level to which the generator
charges the battery, or particularly for solar renewable, by not running the generator in the morning.
If battery charging is in progress and renewable output increases sufficiently to cause the generator charge
power to become negative when averaged over 2 minutes, the PS1 terminates the charge cycle after the
generator minimum run time has expired. If equalize charging was in progress, it is terminated and
rescheduled for the next day Such conditions occur when renewable output exceeds the sum of the load
demand plus the required charge power.
8.3 Automatic Generator Control
The PS1 may be configured to automatically control the generator as required to supply the load and charge
the attached battery or to allow manual control of the generator by the user. Generally automatic control of
the generator is recommended for daily operation.
The generator will only run in automatic mode if the Gen NOT Available LED (LED7) is off. If this LED is
ON, the PS1 will not automatically start the generator. This is controlled via a digital input to the PS1 Generator Available or can be permanently enabled via an installer setting.
As part of the installation, the PS1 settings are configured to automatically run the generator to:
•
Limit the depth of battery discharge, for maximum battery life.
•
Deliver energy efficiently by supplying sustained large loads direct from the generator.
•
Load the generator to the highest possible level while running, to efficiently convert fuel to electricity.
•
Not frequently start and stop the generator, which would reduce its life and increase maintenance.
•
Avoid noise by starting the generator late at night only for heavy loads or a deeply discharged
battery.
In the PS1 RAPS system, the PS1 automatically runs the generator for the following reasons:
•
Battery conditions, in particular state of charge (SoC), require the generator to charge the battery
(see 8.3.1Generator Control based on SoC and 8.3.2 Generator Control based on Battery Voltage).

Technical Manual
PS1 Sinewave Interactive Inverter Charger
•
Load conditions are such that the PS1 ratings are exceeded or a sustained load is large enough to
efficiently load up the generator hence running the generator will be the most efficient method to
supply the load. For loads exceeding the generator rating the PS1 draws power from the battery,
adding its power output to that of the generator (see 8.3.3 Generator Control based on AC Load).
•
Time Schedules are set to regularly run the generator at times of expected peak loads or at
convenient times (see User Manual for details).
•
The generator has not been run for the Exercise period days. The PS1 will start the generator at
the Begin Lvl 1 Hr or 12 noon if Begin Lvl 1 Hr is disabled. Normal automatic stop
conditions apply.
•
Backup Schedules are set to run the generator in case of PS1 shutdown to power vital equipment
(see User Manual for details)
8.3.1
Generator Control based on SoC
The PS1 may be configured to start the generator to charge the battery based on the battery State of
Charge (SoC). This method of generator control is recommended to efficiently and reliably maintain the
battery charge.
The battery SoC is estimated by the PS1 and displayed as a percentage of the battery capacity and
represented throughout this manual and in the menu system by the symbol SoC%.
A daily profile of preferred generator start times and battery charge levels may be configured to allow the
PS1 to automatically start and stop the generator. The profile provides the flexibility to accommodate for
individual site characteristics such as renewable availability, usage patterns and generator noise
considerations.
Several PS1 settings are configured to divide the day into three periods (refer Figure 17):
•
Preferred Hour: The one hour when it is most preferable to run the generator. This is a period
starting at Begin Lvl 1 Hr, typically about 5 or 6pm. During this period the generator is started if
the battery is discharged below Level 1 SoC% to perform a full battery charge.
•
Preferred Period: The period from Begin Lvl 2 Hr to Begin Lvl 3 Hr, when you prefer
the generator to run if the battery state of charge warrants it. The preferred period includes the
preferred hour. During this period the generator is started if the battery is discharged below Level
2 SoC% to perform a full battery charge.
•
Non-Preferred Period: The period from Begin Lvl 3 Hr to Begin Lvl 2 Hr, when you
prefer the generator not to run. This period is usually overnight to avoid noise. During this period
the generator will be started only if the battery is seriously discharged (below Level 3 SoC%) and
will only perform a partial recharge.
If the PS1 starts the generator within the non-preferred period it will run the generator for time determined by
the Gen:Min Run min setting. At other times, once the generator is started, it is run until the battery is fully
charged.
Once the charging is completed the generator will stop unless the load or schedules keep it running. See
8.3.4 Generator Automatic Stopping
The starting time for each of the periods (Begin Lvl 1 Hr , Begin Lvl 2 Hr and Begin Lvl 3 Hr)
can be set via the User menus. The battery state of charge levels (Level 1 SoC% Level 2 SoC% and
Level 3 SoC%) are set by the installer at the time of installation.

Example Configuration 3 – Poor Setup
Figure 19 illustrates a system with levels and times unsuited to the load requirements resulting in failure to
charge the battery adequately to accommodate the overnight load. The battery SoC falls below the Level 3
threshold and the generator is started during the night to stop the battery becoming excessively discharged.
A better generator run strategy would be set the Level 1 or Level 2 settings to cause a charge late in the day
to fully charge the battery before the Level 3 period starts thus averting the generator start overnight.

Generator Control based on Battery Voltage
The PS1 will start the generator based on battery voltage. Normally these limits are not met as the SoC
control will have already started the generator.
The generator will start at any time should any of the pre-configured limits be met.
If the generator starts in the Preferred Period, the PS1 will perform a full battery charge. If the generator
starts in the non-preferred period, the PS1 will perform a partial battery charge.
When complete, the generator will be stopped (see 8.3.4 Generator Automatic Stopping).
8.3.3
Generator Control based on AC Load
The PS1 will automatically start and stop the generator based on the average power delivered to the load
over the time period of the limit. Two factory-configured and two installer configurable settings determine the
power levels at which the generator will be started.
•
The 30 second limit is factory set at 120% of the PS1 rating.
•
The 2 minute limit is factory set at 100% of the PS1 rating.
•
The 10 minute and 30 minute limits are installer configurable.

Page 72 of 97
Technical Manual
PS1 Sinewave Interactive Inverter Charger
The generator will continue to run until the average load power falls below all start limits and all other stop
criteria are met (see 8.3.4 Generator Automatic Stopping).
8.3.4
Generator Automatic Stopping
The PS1 will automatically stop the generator when it is not required for charging the battery or supplying the
load.
If the generator is automatically started in the preferred period, the PS1 will stop it after completion of a
battery charge cycle unless:
•
A generator scheduled run is in progress (see 8.3.5 Generator Scheduling).
•
The average load kW exceeds one of the four configured start limits
(see 8.3.3 Generator Control based on AC Load).
•
The minimum generator run time (Gen:Min Run min) has not expired
•
The generator load is greater than Gen:Min Load kW.
•
The remote run signal is active.
If the generator is automatically started in the non-preferred period, the generator will be stopped after the
minimum generator run time set by Gen:Min Run min unless:
•
A generator scheduled run is in progress (see 8.3.5 Generator Scheduling).
•
The average load kW exceeds one of the four configured start limits
(see 8.3.3 Generator Control based on AC Load).
•
The generator load is greater than Gen:Min Load kW.
•
The remote run signal is active.
The generator will be stopped at midnight if the generator and system load is low except if an equalize
charge is in progress.
8.3.5
Generator Scheduling
Two schedule types are available each with four configurable start times and durations. See User Manual
for full details.
8.4 Manual Generator Control
The generator can be manually controlled via:
•
The generator local controls. The PS1 generator available signal from the generator switch must be
inactive indicated by the Gen NOT Available LED (LED7) being ON.
Note: To prevent reverse power flow into the generator, before manually stopping the generator it is
advisable to open the Generator AC Circuit Breaker and wait until the PS1 LEDs no longer indicate
Inv Sync. After the generator is stopped, close the Generator Circuit Breaker ready for the next
generator start. .
•
The OK pushbutton on the front panel.
•
A Remote Run input that can be wired from the PS1 to a switch in a convenient location such as in
a residence. Several such switches can be wired in parallel. The Gen NOT Available LED (LED7)
must be OFF.
8.4.1
Remote Run Input
The Remote Run switch operates as follows:
•
A switch closure longer than 0.5 seconds and shorter than 2 seconds causes the PS1 to start the
generator. Another such closure stops it, else it is stopped automatically when the battery reaches
full charge and any sustained large load ceases. The switch is typically a non-latching pushbutton.
•
A switch closure longer than 2 seconds causes the PS1 to start the generator, and stop it when the
switch is opened. The switch is typically a latching toggle.

Technical Manual
PS1 Sinewave Interactive Inverter Charger
Regardless of how the generator is started (manually or automatically), while the generator is running the
PS1 automatically charges the battery whenever sufficient generator power is available, and when fully
charged will hold the battery in float charge.
8.5 Generator Fault Recovery
If the PS1 fails three consecutive times to detect significant generator voltage for one minute after a
generator start or, if voltage is detected but fails to synchronise for five minutes, a Generator Fault alarm will
be asserted. The PS1 will then use the following sequence of generator start attempts:
•
After 15 minutes
•
After 1 hour
•
Daily at the Begin Lvl 1 Hr (or 12 noon if Begin Lvl 1 Hr is disabled
A Gen Fail event will be generated and logged each time a start attempt fails.
Note: To force the PS1 to immediately restart the generator toggle the Generator Available input so that the
generator changes to NOT Available then back to Available. Use the OK pushbutton to start the generator.
8.6 Generator Control Interface
The PS1 starts and stops the generator via the control signals shown below. The signals are wired between
the PS1 and the generator local control equipment. The PS1 supports several different generator start/stop
schemes, using some or all of the signals. The system supplier may modify the generator local control
equipment to create the signals, which may have different names within the generator local control
equipment.

Figure 20 Generator Control Signals
Below is a description of the interface operation, for specifications for the generator control interface signals
see Appendix A.3 Generator Control Interface Specification.
8.6.1
Generator Available Signal
The Generator Control Available signal indicates to the PS1 if the generator is available for automatic
control (OFF) or not available (ON). The signal typically comes from a switch on the generator local control
equipment however, it may come from other types of control equipment.
In the OFF position the generator is controlled locally via its own controls, and the PS1 will not try to start or
stop it. The front panel LEDs will indicate Gen Not Available (see ).
In the ON position the generator is available for automatic control by the PS1, for manual control via the PS1
OK pushbutton, and remote control via the Remote Run input signal.
Note: The PS1 may have been set up to not use this signal and assume the generator is always available
for control and hence will ignore this signal.

Technical Manual
8.6.2
PS1 Sinewave Interactive Inverter Charger
Generator Start/Stop Signals:
The PS1 uses the GEN RUN and GEN PULSE signals to start and stop the generator. One or both of these
signals may be used, depending on the generator local control equipment and PS1 setup:
•
If used, the GEN RUN signal remains active while the generator is to run and remains inactive while
the generator is not to run.
•
If used, the GEN PULSE signal becomes active for a short period (“pulse”) to start and to stop the
generator, and is otherwise inactive. The duration of the pulse (typically several seconds), and the
relative timing between the GEN RUN and GEN PULSE signals where both are used, is
determined by PS1 settings configured during installation.
8.6.3
Generator Status Signals:
The GEN FAULT signal indicates a generator fault such as low oil pressure or overheating. The actual
conditions and recommended action should be listed in the generator or site documentation. If the signal
becomes active, the PS1 stops the generator. The PS1 front panel LEDs will indicate Gen Fault, when the
generator fault is fixed and the GEN FAULT signal becomes inactive the PS1 will restart the generator if
required.
The LOW FUEL signal indicates that the fuel tank needs filling as soon as possible. If the signal becomes
active, the PS1 raises a Non Urgent alarm.
The NO FUEL signal indicates that the generator is out of fuel. If the signal becomes active, the PS1 stops
the generator and raises an Urgent alarm. The PS1 front panel LEDs will indicate Gen Abnormal Stop.
8.7 Synchronisation
Whenever the generator and PS1 are both operating, the PS1 automatically synchronises to the generator
(adjusts its AC voltage and frequency to match the generator output) and controls the power flow as
described below. This occurs regardless of how the generator started (manually or automatically). The PS1
will not synchronise to the generator, nor close its relevant contactor, if the generator AC voltage or
frequency is out of tolerance.
Once synchronised, the PS1 will close the Generator Contactor and the front panel LEDs will show
Inv:Sync. If the generator AC voltage or frequency become out of tolerance the PS1 will switch to
standalone mode and try to resynchronize. If unsuccessful for 5 minutes a Generator Fault alarm is
asserted and an automatic restart sequence started.
To prevent the PS1 trying to stay synchronised to a generator that is spinning down, before manually
stopping the generator it is advisable to open the Generator Circuit Breaker and wait until the PS1 LEDs no
longer show Inv Sync. Similarly, if the PS1 automatically stops the generator it will not try to re-synchronise
to the generator for 10 minutes while it spins down. After this period and if generator voltage is still detected,
the PS1 will attempt to resynchronise potentially causing a fault when the generator eventually stops.
8.8 System Power Flow
8.8.1
No Generator/PS1 switched ON
While the PS1 and generator are both off, the AC Contactor and Generator Contactor are both open. If the
PS1 is then switched on it draws power from the renewable and battery to generate AC voltage at nominal
voltage and frequency, and closes its AC contactor to supply the load.
8.8.2
PS1 ON/ Generator Started
While the PS1 is on with no generator voltage present, the AC Contactor remains closed and its Generator
Contactor remains open. If generator voltage is detected by the PS1 (e.g. due to generator start-up), it
synchronises to the generator voltage (adjusts its AC voltage and frequency to match the generator output)
then closes its Generator Contactor. At this stage all of the load power is supplied from the PS1 and zero
power is drawn from the generator. The PS1 then gradually transfers load onto the generator over a period
of 30 to 90 seconds until the power supplied by the inverter is zero. Power is then drawn from the generator
to charge the battery.

Page 75 of 97
Technical Manual
8.8.3
PS1 Sinewave Interactive Inverter Charger
Generator ON/PS1 switched ON
If the generator is running with the PS1 switched off, the AC Contactor is open, and the Generator Contactor
is closed while generator voltage is present, so the generator supplies the load. If the PS1 is then switched
on, it synchronises to the generator voltage (adjusts its AC voltage and frequency to match those of the
generator) then closes its AC Contactor, and draws generator power to charge the battery.
8.8.4
Load Sharing
While the PS1 and generator are both on and synchronised, the PS1 charges the battery while the load is
below the generator power rating. If the load exceeds the generator rating, the PS1 does not charge the
battery but draws power from it, adding its power output to that of the generator to supply the load, and
limiting the power drawn from the generator.
8.8.5
Reverse Power
If the generator trips while running, for example due to running out of fuel or being manually stopped, then
AC power may flow into the generator. This is not a desirable condition. The PS1 detects this condition and
opens its Generator Contactor.
8.8.6
Reactive Power
Reactive power flow (kVAr) occurs when the AC current in a circuit is out of phase with the AC voltage.
Reactive power flow consists of energy flowing back and forth in consecutive AC half cycles. It performs no
useful function, and increases the current above that due to real power flow (kW) alone, so causing
increased power loss and heating which may limit the real power available.
Reactive power flow occurs in reactive system loads such as induction motors. The PS1 shares such
reactive flows with the generator, by controlling the AC output voltage.
The amount of reactive power flow can be monitored using parameters Inv kVAr and Gen kVAr.
8.9 Inverter External Alarm
The PS1 provides a single alarm output which can be wired to an external alarm buzzer or light etc. An
urgent alarm is indicated by a continuous ON condition and a non-urgent alarm is indicated by a slow
intermittent ON/OFF condition. If the PS1 is shutdown or OFF the urgent alarm output is be asserted.
NON-URGENT conditions can be prevented from raising the alarm, via the LCD displays.
The URGENT and NON-URGENT alarms are also separately indicated on the front panel LEDs. Short term
and long term event counters are provided and the users may set limits for each to generate alarms.
See User manual for full control options.

9 Troubleshooting
System problems in the field may be due to:
•
Incorrect generator or renewable adjustment.
•
Incorrect inverter settings.
•
Failure of the generator, renewable, battery, wiring, inverter, control equipment, etc.
9.1 System General Check
If the system is not operating correctly, perform a general check as follows:
Check if the inverter front panel LCD and LEDs indicate a problem, and take the recommended action. Use
the
button to review the past events on the LCD.
Switch off the inverter via its On/Off button for a few seconds then back on. Again check if the front panel
LCD and LEDs indicate a problem, and take the recommended action.
9.2 Inverter will not Start
If the LEDs remain off when the inverter is switched on via its On/Off button, the inverter did not start.
This may occur if the battery is excessively discharged, since the inverter electronics are powered from the
DC (battery) side not the AC (generator) side. Check the battery voltage – if less than the restart voltage
(Inv:Restart V ), the inverter will not start. Turn off all loads to minimize battery drain, and allow the
battery several minutes to recover. If the inverter still will not start, the battery must be at least partially
recharged, from renewables for example. If the battery voltage is now ok and the inverter starts, start the
generator and recharge the battery bank.
9.3 No AC Power to Load while Generator Off
Check AC Load Circuit breaker has not tripped. Check distribution board circuit breakers.
Check if the inverter front panel LCD and LEDs indicate a problem, and take the recommended action.
9.4 Inverter Not Charging Battery
Check if the inverter front panel LCD and LEDs indicate a problem, and take the recommended action.
Is the AC load too high and there is no power capacity from the generator to charge the battery?
Is the DC Fuse blown or DC circuit breaker tripped? (see 9.7 DC Circuit Breaker Trips)
9.5 Inverter Shuts Down
Whenever the inverter shuts down, it attempts to restart. If the cause persists and ten restarts have
accumulated within one minute, further restarts will be attempted once per minute.
The inverter shuts down automatically for the following conditions, which should be investigated:
•
Overload
•
DC over-voltage and under-voltage
•
Over-temperature
•
AC over-voltage and under-voltage

•
PS1 Sinewave Interactive Inverter Charger
Excessive battery discharge
Check if the inverter front panel LCD and LEDs indicate a problem, and take the recommended.
Starting a large motor can overload the inverter, especially if the motor takes several seconds to start
spinning. If the overload persists, the inverter will shut down but will automatically restart. Check that the
inverter will start the motor with other AC Load combinations.
9.6 Inverter – No Front Panel display
If the inverter is not running, the front panel LCD, LEDs and buttons will be dead, and no AC or DC power
will flow in the inverter. (see 9.2 Inverter will not Start)
Switch off the inverter via its On/Off button for a few seconds then back on. If this does not restore normal
operation, again check if the front panel LCD and LEDs indicate a problem, and take the recommended.
Is the DC Fuse blown or DC circuit breaker tripped? (see 9.7 DC Circuit Breaker Trips)
9.7 DC Circuit Breaker Trips
DC circuit breaker trip may be due to battery under voltage. Check if the front panel LEDs indicate a
problem, and take the recommended.
Inspect for a short circuit in the DC wiring.
This may be due to a DC fault current. The inverter will stop operating, and may be faulty. Switch off the
inverter via its On/Off button for a few seconds then back on. The built in self-test will check for any possible
DC fault paths and indicate any problems on the LCD/LEDs. Take the recommended action.
If faulty, run the generator manually to supply the loads.
9.8 Inverter does not start Generator
Check that, if fitted, the externally wired generator available control switch is closed. The inverter front panel
Gen NOT Avail LED indication should be OFF. If not, the inverter cannot control the generator. See 3.5
Generator Control Wiring
Check if the inverter front panel LCD and LEDs indicate a problem, and take the recommended action.
Switch the inverter On/Off button off for a few seconds then back on. If this does not restore normal
operation, check if the front panel LCD and LEDs now indicate a problem, and take the recommended
action.
With the inverter switched off and the externally wired generator available control switch in the open position,
check that the generator can be manually started via its own controls and runs smoothly with customer load
applied i.e. no fuel blockage, correct voltage and frequency.
With the inverter switched on and the externally wired generator available control switch is closed, check that
the generator can be started and stopped using the OK button on the inverter front panel. If not, check
wiring and interface signals.
Check that the generator running requirements are correctly set up. See 6.3 Generator settings.
9.9 Inverter does not synchronise to Generator
The inverter cannot synchronise to the generator because the generator AC voltage or frequency is too high
or low. Check the LCD displays of measured generator voltage, frequency and frequency variation
(readings Gen VAC, Gen Hz and Gen var Hz).
Check the inverter tolerance settings Sync Tol VAC, Sync Hi Hz and Sync Lo Hz.
The generator governor speed setting or AC voltage may need adjustment. Consult the generator user
manual.

Technical Manual
PS1 Sinewave Interactive Inverter Charger
9.10 Inverter synchronises but disconnects due to
reverse power flow.
There are several reasons and resolutions for the inverter disconnecting from the generator with the reason
of reverse power flow.
•
Bad battery temperature reading
Check battery temperature and ensure operating correctly.
•
Battery voltage held high by external charging source.
Check external charging sources are operating correctly.
•
Incorrect AVR sensing.
Check that the AVR in the alternator is correctly sensing the terminals that the load/inverter is
connected to.
•
Poor generator frequency stability
Test generator stability on loads without the inverter connected. Generator frequency instability or
“hunting” is indicated by the noise of the generator speeding up and slowing down without any change in
load. Frequency stability may be adjusted on some types of governors. Consult generator manual.
Changing to a lower Gen Type may correct this.
Decreasing (a more negative number) the PS1 Period Gain may also correct this. This requires
that the Gen Type be set to 3 and adjust the Gen Type 3 settings. See 6.3 Generator settings
•
Low generator frequency droop.
The generator may not droop (reduce) or not droop sufficiently in frequency when load is applied.
Droop may be adjusted on some types of engine governors. Consult generator manual. Droop may be
adjusted by increasing the no load engine speed. Note that this speed must be below the high frequency
disconnect point and if the alternator uses compound regulator the gap will need to be adjusted to keep the
output voltage within the desired range.
Decreasing the PS1 Proportional Gain may also correct this. This requires that the Gen Type be
set to 3 and adjust the Gen Type 3 settings. See 6.3 Generator settings
•
Poor generator voltage regulation.
The alternator output voltage may increase when load is applied or may be significantly distorted.
Many AVR type regulators have adjustments to change the response of the output voltage to changing
loads. The regulator may need to be upgraded to a more sophisticated device designed to be used on
generators operated in parallel.
9.11 Inverter & Generator Load Sharing Incorrect
Is the load within the combined rating of inverter plus generator?
Switch off the inverter On/Off button, manually run the generator, and check whether the generator supplies
the load in a stable manner. The generator governor speed setting may need adjustment.
Is the inverter setup correct? Check relevant settings in the menu system.
Check the generator AC voltage and current measurement
Check the inverter AC voltage and current measurement
9.12 Generator Runs at the Wrong Times
For example, the generator starts late at night and then never starts until the middle of the day.
The time of day clock may be incorrectly set (see settings Time:Set Hour and Time:Set Min).

Document PC0009 Revision 04
Page 79 of 97
Technical Manual
PS1 Sinewave Interactive Inverter Charger
Check that the overnight load is not excessive, and that the battery has not lost capacity and is forcing the
generator to start prematurely.
9.13 The Generator Runs for a Long Time
It may be doing an Equalise charge which can take some hours to complete; check if the Equalise indicator
is flashing. The charging setup may need adjustment.
There may be a sustained load on the system. Check to see that appliances have not been left on.
If you need to manually stop the generator. If the generator restarts a minute or so later then the battery is
discharged, the battery volts are low or a load is present. You can shut the generator down permanently by

10 Inverter Shutdown & Isolation Procedures
Hazardous voltages and energy are generated in the inverter, are fed into the inverter by external wiring
from multiple sources, and may be stored in capacitors after the inverter is switched off and disconnected
from external wiring. The procedures below are to be performed only by suitably qualified and trained
personnel, and only with suitable safety precautions. Before performing any work on the inverter or opening
its front door, please refer to
To avoid safety hazards or inverter damage, perform the §10.2 Inverter Isolation Procedure and the §10.3
Inverter Discharge Procedure below before disconnecting/reconnecting any cables in the inverter.
10.1 Inverter Shutdown Procedure
Use this procedure to shut down the inverter:
1. Switch off the inverter by pressing the inverter On/Off button for a second, checking all the LEDs go
off.
2. Unless the generator is to supply the load via the inverters Generator Contactor, open the
GENERATOR AC and LOAD circuit breakers.
3. Open the DC circuit breaker if desired (in any case, it will trip automatically 15 minutes after the
inverter is switched off.)
To shut down and isolate the inverter from all energy sources, for example to work on it or replace it, use the
Inverter Isolation Procedure below.
10.2 Inverter Isolation Procedure
Before working inside the inverter, or on the external wiring connected to its AC and DC power terminals,
use this procedure to isolate the inverter and the wiring from all external AC and DC energy sources:
1. Switch OFF the inverter using the On/Off button, and check all LEDs go off. The generator may still
be supplying the load via the inverters Generator Contactor.
2. If the generator is to supply the load while the inverter is isolated, close the inverter bypass switch
on the switchboard (if fitted).
3. Remove AC voltage from the inverter terminals, by opening the inverter isolator on the switchboard.
4. Open the GENERATOR AC and LOAD circuit breakers.
5. Open the DC circuit breaker, to stop any large DC current flowing in the inverter DC wiring.
6. If the ganged DC fuse assembly does not support on-load extraction/insertion, switch off the
renewable regulator to stop DC current flow through the ganged fuse assembly.
7. Open the ganged DC fuse assembly (or ganged circuit breaker if used), to remove battery and
renewable voltage from the inverter terminals.
8. Open the inverter front door. Confirm with a voltmeter or voltage detector that negligible AC voltage
is present on the inverter AC terminals, and that negligible DC voltage is present on the inverter DC
terminals.
9. Hazardous DC voltage may remain on capacitors inside the inverter. Before working inside the
inverter, discharge the capacitors using §10.3 Inverter Discharge Procedure.
10.3 Inverter Discharge Procedure
When the inverter has been isolated using §10.2 Inverter Isolation Procedure, use the following procedure to
discharge the Power PCA capacitors:
1. To prevent electrostatic damage to electronic components inside the inverter, discharge yourself by
touching the earthed unpainted inverter frame.
2. Momentarily join the two pins of J11 on the Power PCA (see §7.1 Inverter Internal View) for J11
location on the PCA). This will cause the Power PCA to discharge the capacitors.
3. Wait for about 30 seconds for the capacitors to discharge to a low level.

Page 81 of 97
Technical Manual
PS1 Sinewave Interactive Inverter Charger
4. Ensure the capacitors have been discharged, by measuring their DC voltage between the inverters
Battery Negative terminal and the inverter side of the DC circuit breaker.
10.4 Inverter De-isolation Procedure
After the inverter and its wiring have been isolated using §10.2 Inverter Isolation Procedure, use this
procedure to remove the isolation and restore the inverter to service:
1. Ensure the inverters DC circuit breaker is open.
2. Close the inverters LOAD and GENERATOR AC Circuit Breakers.
3. Close the inverter isolator on the switchboard.
4. Open the inverter bypass switch on the switchboard. If the generator is running it will now be
supplying the load via the inverters Generator Contactor.
5. If the ganged DC fuse assembly does not support on-load extraction/insertion, switch off the
renewable regulator to stop DC current flow through the ganged fuse assembly.
6. Close the ganged fuse assembly (or ganged circuit breaker if used). Switch on the renewable
regulator.
7. Switch on the inverter using the On/Off button, and check that the LEDs show successful inverter
self-test and start-up.
8. Close the DC circuit breaker when requested by the LCD display.
10.5 Inverter Start-up Procedure
Use this procedure to start up the inverter:
1. If not already closed, close the Generator Circuit Breaker.
2. If not already closed, close the LOAD circuit breaker.
3. Switch on the inverter by pressing the inverter On/Off button for a second, checking the LEDs then
indicate start-up (see inverter User section of this manual). If the inverter had shut down from an
abnormal cause, it may be necessary to operate the On/Off button several times.
4. When the inverters' internal capacitors have pre-charged, the LCD will display "Please close DC CB
below". Then close the DC circuit breaker.
5. The self-test will run, and when complete, the inverter will start running and synchronise to the
generator.
