1.ImportantSafetyInformation
WARNING!
This manual contains important instructions for all AP/APP/APS/APV
Inverter/Charger models that shall be followed during installation and
maintenance of the inverter.
1‐1.GeneralSafetyPrecautions
1-1-1.Do not expose the Inverter to rain, snow, spray, bilge or dust. To reduce risk of hazard, do not cover or
obstruct the ventilation openings. Do not install the Inverter in a zero-clearance compartment. Overheating
may result. Allow at least 30CM(11.81 inches) of clearance around the inverter for air flow. Make sure that
the air can circulate freely around the unit. A minimum air flow of 145CFM is required.
1-1-2. To avoid a risk of fire and electronic shock. Make sure that existing wiring is in good electrical
condition; and that wire size is not undersized. Do not operate the Inverter with damaged or substandard
wiring.
1-1-3. This equipment contains components which can produce arcs or sparks. To prevent fire or explosion
do not install in compartments containing batteries or flammable materials or in locations which require
ignition protected equipment. This includes any space containing gasoline-powered machinery, fuel tanks,
or joints, fittings, or other connection between components of the fuel system.
See Warranty for instructions on obtaining service.
1-1-4. Do not dis-assemble the Inverter/Charger. It contains no user serviceable parts. Attempting to service
the Inverter/Charger yourself may result in a risk of electrical shock or fire. Internal capacitors remain
charged after all power is disconnected.
1-1-5. To reduce the risk of electrical shock, disconnect both AC and DC power from the Inverter/Charger
before attempting any maintenance or cleaning. Turning off controls will not reduce this risk
CAUTION: Equipment damage
The output side of the inverter’s AC wiring should at no time be connected to public power or a generator.
This condition is far worse than a short circuit. If the unit survives this condition, it will shut down until
corrections are made.
Installation should ensure that the inverter’s AC output is, at no time, connected to its AC input.
Warning: Limitations On Use
SPECIFICALLY, PLEASE NOTE THAT THE AP/APP SERIES INVERTER/CHARGER SHOULD NOT
BE USED IN CONNECTION WITH LIFE SUPPORT SYSTEMS OR OTHER MEDICAL EQUIPMENT
OR DEVICES.
1‐2.PrecautionsWhenWorkingwithBatteries
1-2-1. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye,
immediately flood eye with running cold water for at least 20 minutes and get medical attention
immediately.
1-2-2. Never smoke or allow a spark or flame in vicinity of battery or engine.
-3-
Line-Interactive Technology
1-2-3. Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery of other
electrical part may cause an explosion.
1-2-4. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
lead-acid battery. A lead-acid battery produces a short-circuit current high enough to weld a ring or the like
to metal, causing a severe burn.
1-2-5. To reduce the risk of injury, charge only rechargeable batteries such as deep-cycle lead acid, lead
antimony, lead calcium gel cell, absorbed mat, NiCad/NiFe or Lithium battery. Other types of batteries may
burst, causing personal injury and damage.

Topology
The AP/APP/APS/APV inverter/charger is built according to the following topology.
Inverter: Full Bridge Topology.
AC Charger: Isolate Boost Topology
Because of high efficiency Mosfets and 16bit, 4.9MHz microprocessor and heavy transformers, it outputs
PURE SINE WAVE AC with an average THD of 10% (Min5%, Max 15%) depending of load connected
and battery voltage.
The peak efficiency of AP/APP series is 88%.

Line-Interactive Technology
Overload Capacity
The AP/APP/APS/APV series inverters have different overload capacities, making it ideal to handle
demanding loads.
1 For 110%<Load<125%(±10%), no audible alarm in 14 minutes, beeps 0.5s every 1s in the 15th minute,
and Fault(Turn off) after the 15th minute.
2 For 125%<Load<150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after the 1 minute.
3 For 300%≧Load>150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after 20s.
2.5.2ACCharger
AP/APP/APS/APV Series is equipped with an active PFC (Power Factor Corrected) multistage battery
charger. The PFC feature is used to control the amount of power used to charge the batteries in order to
obtain a power factor as close as possible to 1.
Unlike other inverters whose max charging current decreases according to the input AC voltage, AP/APP
series charger is able to output max current as long as input AC voltage is in the range of 164-243VAC
(95-127VAC for 120V model), and AC freq is in the range of 48-54Hz(58-64Hz for 60Hz model).
The AP/APP series inverter is with a strong charging current of 120Amp (for 4KW,12V), and the max
charge current can be adjusted from 0%-100% via a liner switch at the right of the battery type selector. This
will be helpful if you are using our powerful charger on a small capacity battery bank. Fortunately, the liner
switch can effectively reduce the max charging current to 20% of its peak.
Choosing “0” in the battery type selector will disable charging function.
There are mainly 3 stages:
Bulk Charging: This is the initial stage of charging. While Bulk Charging, the charger supplies the battery
with controlled constant current. The charger will remain in Bulk charge until the Absorption charge voltage
(determined by the Battery Type selection) is achieved.
Software timer will measure the time from A/C start until the battery charger reaches 0.3V below the boost
voltage, then take this time asT0 and T0×2 = T1.
Absorb Charging: This is the second charging stage and begins after the absorb voltage has been reached.
Absorb Charging provides the batteries with a constant voltage and reduces the DC charging current in order
to maintain the absorb voltage setting.
In this period, the inverter will start a T1 timer; the charger will keep the boost voltage in Boost CV mode
until the T1 timer has run out. Then drop the voltage down to the float voltage. The timer has a minimum
time of 1 hour and a maximum time of 12 hours.
Float Charging: The third charging stage occurs at the end of the Absorb Charging time. While Float
charging, the charge voltage is reduced to the fl oat charge voltage (determined by the Battery Type
selection*). In this stage, the batteries are kept fully charged and ready if needed by the inverter.
If the A/C is reconnected or the battery voltage drops below 12Vdc/24Vdc/48Vdc, the charger will reset the
cycle above.
If the charge maintains the float state for 10 days, the charger will deliberately reset the cycle to protect the
battery.

De-sulphation
The de-sulphation cycle on switch position 8 is marked in red because this is a very dangerous setting if you
do not know what you are doing. Before ever attempting to use this cycle you must clearly understand what
it does and when and how you would use it.
What causes sulphation? This can occur with infrequent use of the batteries(nor), or if the batteries have
been left discharged so low that they will not accept a charge. This cycle is a very high voltage charge cycle
designed to try to break down the sulphated crust that is preventing the plates taking a charge and thus allow
the plates to clean up and so accept charge once again.
Charging depleted batteries
The AP/APP/APS/APV series inverter allows start up and through power with depleted batteries.
For 12VDC model, after the battery voltage goes below 10V, if the switch is still (and always) kept in "ON"
position, the inverter is always connected with battery, and the battery voltage does not drop below 2V, the
inverter will be able to charge the battery once qualified AC inputs are present.
Before the battery voltage goes below 9VDC, the charging can be activated when the switch is turned to
“Off”, then to “ON”.
- 13 -
Line-Interactive Technology
When the voltage goes below 9VDC, and you accidently turn the switch to OFF or disconnect the inverter
from battery, the inverter will not be able to charge the battery once again, because the CPU loses memory
during this process.

2.000 4.000 6.000 The charging capacity will go to peak in around 3 seconds. This may cause a generator to drop frequency,
making inverter transfer to battery mode.
It is suggested to gradually put charging load on the generator by switching the charging switch from min to
max, together with the 15s switch delay, our inverter gives the generator enough time to spin up. This will
depend on the size of the generator and rate of charge.
2.5.3Transfer
While in the Standby Mode, the AC input is continually monitored. Whenever AC power falls below the
VAC Trip voltage (154 VAC, default setting for 230VAC,90VAC for 120VAC), the inverter automatically
transfers back to the Invert Mode with minimum interruption to your appliances - as long as the inverter is
turned on. The transfer from Standby mode to Inverter mode occurs in approximately 8 milliseconds. And it
is the same time from Inverter mode to Standby mode.
Though it is not designed as a computer UPS system, this transfer time is usually fast enough to keep your
equipment powered up.
There is a 15-second delay from the time the inverter senses that continuously qualified AC is present at the
input terminals to when the transfer is made. This delay is built in to provide time for a generator to spin-up
to a stable voltage and avoid relay chattering. The inverter will not transfer to generator until it has locked
onto the generator’s output. This delay is also designed to avoid frequent switching when input utility is
unstable.
2.5.4Autofrequencyadjust
The inverter is with Auto Frequency adjust function.
The factory default configuration for 220/230/240VAC inverter is 50Hz, and 60Hz for 100/110/120VAC
inverter. While the output freq can be easily changed once a qualified freq is applied to the inverter.
If you want to get 60Hz from a 50Hz inverter, just input 60Hz power, and the inverter will automatically
adjust the output freq to 60Hz and vice versa.

the battery.
Maximum Power Point Tracking (MPPT) Function
Maximum Power Point Tracking, frequently referred to as MPPT, is an electronic system that operates the
Photovoltaic (PV) modules in a manner that allows the modules to produce all the power they are capable of.
The PV-seeker Charge controller is a microprocessor-based system designed to implement the MPPT.

Line-Interactive Technology
And it can increase charge current up to 30% or more compared to traditional charge controllers (see figure
1).
Figure 1 Current, Power vs. Voltage Characteristics
The Charge controller built in is with 12/24V battery voltage auto detecting function.
For 12VDC inverter, the output voltage of solar charger will be accordingly 12VDC, and the qualified DC
input volt range is 15v-30VDC.
For 24VDC inverter, the output voltage of solar charger will be accordingly 24VDC, and the qualified DC
input volt range is 30v-55VDC.
If the voltage falls out of this range, the charger will not work properly. Special attention should be paid to
this when configuring the solar array.
2.5.6AutomaticVoltageRegulation
The automatic voltage regulation function is for full series of APS Pure Sine Wave Inverter/ Charger except
Instead of simply bypassing the input AC to power the loads, the APS series inverter stabilizes the input AC
voltage to a range of 230V/120V±10%.
Connected with batteries, the APS Series inverter will function as a UPS with max transfer time of 10 ms.
With all the unique features our inverter provides, it will bring you long-term trouble free operation beyond
your expectation.

2.5.7PowerSaverMode
There are 3 different working status for AP/APP/APS/APV inverter: “Power Saver Auto” 、“Power Saver
Off” and “Power Off”.
When power switch is in “Unit Off” position, the inverter is powered off.
When power switch is turned to either of “Power Saver Auto” or “Power Saver Off”, the inverter is powered
on.
Power saver function is designed to conserve battery power when AC power is not or rarely required by the
loads.
In this mode, the inverter pulses the AC output looking for an AC load (i.e., electrical appliance). Whenever
an AC load (greater than 25 watts) is turned on, the inverter recognizes the need for power and automatically
starts inverting and output goes to full voltage. When there is no load (or less than 25 watts) detected, the
inverter automatically goes back into search mode to minimize energy consumption from the battery bank.
In “Power saver on” mode, the inverter will draw power mainly in sensing moments, thus the idle
consumption is significantly reduced.
The inverter is factory defaulted to detect load for 250ms every 30 seconds. This cycle can be customized to
3 seconds turn SW3 on the DIP switch.
Power saver on
Power saver off
- 17 -
Power saver on (Load detected)
Line-Interactive Technology
Note: The minimum power of load to take inverter out of sleep mode (Power Saver On) is 25 Watts.
When in the search sense mode, the green power LED will blink and the inverter will make a ticking sound.
At full output voltage, the green power LED will light steadily and the inverter will make a steady humming
sound. When the inverter is used as an “uninterruptible” power supply the search sense mode or “Power
Saver On” function should be defeated.
Exceptions
Some devices when scanned by the load sensor cannot be detected. Small fluorescent lights are the most
common example. (Try altering the plug polarity by turning the plug over.) Some computers and
sophisticated electronics have power supplies that do not present a load until line voltage is available. When
this occurs, each unit waits for the other to begin. To drive these loads either a small companion load must
be used to bring the inverter out of its search mode, or the inverter may be programmed to remain at full
output voltage.
2.5.8Protections
The AP/APP/APS/APV series inverter is equipped with extensive protections against various harsh
situations/faults.
These protections include:
AC Input over voltage protection/AC Input low voltage protection
Low battery alarm/High battery alarm
Over temperature protection/Over load protection
Short Circuit protection (1s after fault)
Back feeding protection
When Over temperature /Over load occur, after the fault is cleared, the master switch has to be reset to
restart the inverter.
The Low batter voltage trip point can be customized from defaulted value 10VDC to 10.5VDC thru the SW1
on DIP switch.
The inverter will go to Over temp protection when heat sink temp. ≥105ºC, and go to Fault (shutdown
Output) after 30 seconds. The switch has to be reset to activate the inverter.
The AP/APP series Inverter has back feeding protection which avoids presenting an AC voltage on the AC
input terminal in Invert mode.
After the reason for fault is cleared, the inverter has to be reset to start working.
2.5.9Remotecontrol(Optional)
- 18 -
Line-Interactive Technology
Apart from the switch panel on the front of the inverter, an extra switch panel connected to the RJ11 port at
the DC side of the inverter thru a standard telephone cable can also control the operation of the inverter.
If an extra switch panel is connected to the inverter via “remote control port”, together with the panel on the
inverter case, the two panels will be connected and operated in parallel.
Whichever first switches from “Off” to “Power saver off” or “Power saver on”, it will power the inverter on.
If the commands from the two panels conflict, the inverter will accept command according to the following
priority:
Power saver on> Power saver off> Power off
Only when both panels are turned to “Unit Off” position will the inverter be powered off.
The Max length of the cable is 10 meters.
WARNING
Never cut the telephone cable when the cable is attached to inverter and battery is connected to the inverter.
Even if the inverter is turned off. It will damage the remote PCB inside if the cable is short circuited during
cutting.

2.5.12FANOperation For 1-3KW, there is one multiple controlled DC fan which starts to work according to the following logic.
For 4-6KW, there is two multiple controlled DC fan and one AC fan. The DC fan will work in the same way
as the one on 1-3KW, while the AC fan will work once there is AC output from the inverter.
So when the inverter is in power saver mode, the AC fan will work from time to time in response to the
pulse sent by the inverter in power saver mode.
The Operation of the DC fan at the DC terminal side is controlled by the following logic
(Refer to Table 2.5.10):

Allow at least 30CM of clearance around the inverter for air flow. Make sure that the air can circulate freely
around the unit.
Variable speed fan operation is required in invert and charge mode. This is to be implemented in such a way
as to ensure high reliability and safe unit and component operating temperatures in an operating ambient
temperature up to 50°C.
• Speed to be controlled in a smooth manner as a function of internal temperature and/or current.
• Fan should not start/stop suddenly.
• Fan should run at minimum speed needed to cool unit.
• Fan noise level target <60db at a distance of 1m.
2.5.13DIPSwitches
On the rear panel of inverter, there are 4 DIP switches which enable users to customize the performance of
the device.

SW1:Low Battery Trip Volt:
For 12VDC model, the Low Battery Trip Volt is set at 10.0Vdc by typical deep cycle lead acid battery. It
can be customized to 10.5Vdc using SW1 for sealed car battery, this is to prevent batteries from
over-discharging while there is only a small load applied on the inverter.(*2 for 24VDC, *4 for 48VDC)
SW2:AC Input Range:
There are different acceptable AC input ranges for different kinds of loads.
For some relatively sensitive electronic devices, a narrow input range of 184-253VAC (100-135V for
120VAC model) is required to protect them.
While for some resistive loads which work in a wide voltage range, the input AC range can be customized to
154-253VAC (90-135V for 120VAC model), this helps to power loads with the most AC input power
without frequent switches to the battery bank.
SW3:Power Saver Auto Setting :
The inverter is factory defaulted to detect load for 250ms in every 5 seconds. This cycle can be customized
to 3 seconds through the SW3 on the DIP switch.
SW4:Solar/AC Priority:
Our inverter is designed with AC priority by default. This means, when AC input is present, the battery will
be charged first, and the inverter will transfer the input AC to power the load. Only when the AC input is
stable for a continuous period of 15 days, the inverter will start a battery inverting cycle to protect the
battery. After 1 cycle normal charging and ac through put will be restored.
The AC Priority and Battery Priority switch is SW4. When you choose battery priority, the inverter will

point(10.5V for 12V), the inverter transfers to AC Input, charges battery, and switches back to battery when
battery is charged full. This function is mainly for wind/solar systems taking utility power as back up.
2.5.14Otherfeatures
Battery voltage recover start
After low battery voltage shut off (10V for 12V model/20V for 24V model/40V for 48V model), the inverter
is able to restore operation after the battery voltage recovers to 13Vdc/26Vdc/52Vdc (with power switch still
in the “On” position). This function helps to save the users extra labor to reactivate the inverter when the
low battery voltage returns to an acceptable range in the renewable energy systems. The built in battery
charger will automatically reactivate as soon as city/generator ac has been stable for 15 seconds.
WARNING
Never leave the loads unattended, some loads (like a Heater) may cause accident in such cases.
It is better to shut everything down after low voltage trip than to leave your load on, due to the risk of fire.
Auto Gen Start(optional)
The inverter can be customized to start up a generator when battery voltage goes low.
When the inverter goes to low battery alarm, it can send a signal to start a generator, and turn the generator
off after battery charging is finished.
The auto gen start feature will only work with generators designed to work with this feature. There is an
open/close relay that will short circuit the positive and negative cable from a generator. The input DC
voltage can vary, but the Max current the relay can carry is 16Amp.
Conformal Coating
The entire line of inverters have been processed with a conformal coating on the PCB, making it water, rust,
and dust resistant.
While these units are designed to withstand corrosion from the salty air, they are not splash proof.

One cable is always best , but cable is simply copper and all you require is the copper, so it does not matter if it is one
cable or 10 cables as long as the square area adds up. Performance of any product can be improved by thicker cable
and shorter runs, so if in doubt round up and keep the length as short as possible.
3.3ACWiring
We recommend using 10-5Awg wire to connect to the ac terminal block.
There are 3 different ways of connecting to the terminal block depending on the model. All the wirings are CE
compliant, Call our tech support if you are not sure about how to wire any part of your inverter.

Noise from Transformer/case*
Applying specific loads such as
Remove the loads
hair drier
*The reason for the noise from transformer and/or case
When in inverter mode and the transformer and/or case of the inverter sometimes may vibrate and make
noise.
The noise may come from transformer.
According to the characteristics of our inverter, there is one type of load which will most likely to cause
rattles of transformer, that is a half-wave load, load that uses only a half cycle of the power(see figure 1).
This trends to cause imbalance of magnetic field of transformer, reducing its rated working freq from
20KHz to, say, maybe 15KHz (it varies according to different loads). This way, the freq of noise falls
exactly into the range (200Hz-20KHz) that human ear can sense.
The most common load of such kind is hair drier.
Figure 1
If the noise comes from case.
Normally when loaded with inductive loads, the magnetic field generated by transformer keeps attracting or
releasing the steel case at a specific freq, this may also cause noise.
Reducing the load power or using an inverter with bigger capacity will normally solve this problem.
The noise will not do any harm to the inverter or the loads.
