1. Introduction
1.1 Introduction of Inverter
The APS series inverter not only is an inverter but also contains a powerful
smart charger. Actually, it contains three modules in a single unit: inverter,
charger and switch.
The APS series inverter is a heavy-duty, continuous working module
generating a sinusoidal wave from a 12V/24V/48V - battery bank, which
can supply energy to various loads such as resistive load
(heater),inductive load (air conditioners, refrigerator),motors (vacuum
cleaners), and rectifier load (computer). All SL series are designed to work
in heavy load condition. De-rating is not necessary. It provides a rapid and
complete charging process.
The smart charger can be set with different charging profiles and battery
capacities to match in various battery types and sizes. The switch module
automatically diverts the energy transfer path between inverter and utility
source. When the utility source is lower than the transfer level, the path
switches to the inverter. Otherwise the load is conducted to the utility
source. The transfer time is 1/4~1/2 of the total cycle time. The high power
charger (80A) can charge a 12V/1000 AH battery bank in 14 hours. For
example, a single unit of Inverter APS 2012 with a 1000 AH battery bank
can supply a 2000W workload for over 6 hours after a charge of 14 hours.
APS series is an extremely good choice for utility back up power. However,
it also can be used as a UPS for computers.
An inverter, charger and switching box can be replaced with a single EPS
series unit.
1.2 Important Safety Instructions
1.2.1 General Precautions
1. Before using the APS inverter, please read all instructions and
cautionary marks on (1) the inverter, (2) the batteries, and (3) all
appropriate sections of this instruction manual.
2. Do not expose APS INVERTER to rain, snow, or liquids of any type.
The APS INVERTER is designed for indoor mounting only. Protect the
inverter from splashing if used in vehicle applications.
3. Do not disassemble the APS INVERTER; take it to a qualified service
center when service or maintenance is required. Incorrect re-assembly
may result in risk of electric shock or fire.
1
4. To reduce risk of electric shock, disconnect all wiring before making
any attempt to maintain or clean. Simply turning off the INVERTER will
not reduce this risk.
5. WARNING: WORKING IN THE VICINITY OF A LEAD ACID
BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE
GASES DURING NORMAL OPERATION. Provide ventilation to
outdoors from the battery compartment. The battery enclosure should
be designed to prevent accumulation and concentration of hydrogen
"pockets" at the top of the compartment. Vent the battery compartment
from the highest point. A sloped lid can also be used to direct the flow
through the vent opening location.
6. NEVER charge a frozen battery.
7. No terminals or lugs are required for hook-up of the AC wiring. AC
wiring must be no less than 10 AWG(5.3mm2 ) gauge copper wire and
rated for 75Amp or higher and should be no less than 20
AWG(67.4mm2 ) gauge. Crimped and sealed copper ring terminal lugs
with a 5/16 inch hole should be used to connect the battery cables to
the DC terminals of the INVERTER. Soldered cable lugs are also
acceptable .See section on battery cable sizing for more details for
your application.
8. Torque all AC wiring connections to 15-20 inch-pounds. Torque all DC
cable connections to 10-12 foot-pounds .Be extra cautious when
working with metal tools on or around batteries. The potential of
dropping a tool causing the batteries or other electrical parts resulting
in sparks could cause an explosion. Tools required for AC wiring
connections: wire strippers, 1/2"(13mm2) open-end wrench or socket,
Phillips screw driver #2, slotted screw driver 1/4"(6 mm2) blade.
9. The INVERTER must be used with a battery supply of nominal voltage
that matches the last two digits of the model number; e.g., 12 volts
with APS1012, APS1512, APS2012, APS3012 or 24 volts with a
APS1024, APS1524, APS2024 , APS3024, APS4024, APS5024,
APS6024and 48 volts with a APS3048, APS4048, APS5048,
APS6048.
10.GROUNDING INSTRUCTIONS. This battery charger should be
connected to a grounded, permanent wiring system. For most
installations, the negative battery conductor should be bonded to the
grounding system at one, and only one, point in the system. All
installations should comply with all national and local codes and
ordinances.
2
1.2.2 Personal Precautions
1. Someone should be within voice range when you work near batteries
in case of an emergency.
2. Have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing, or eyes.
3. Wear complete eye and clothing protection. Avoid touching eyes while
working near batteries. Wash your hands when done.
4. If battery acid contacts skin or clothing, immediately wash with soap. If
acid enters eyes immediately, flood eyes with cool, running water for
at least 15 minutes. Immediately seek medical attention.
5. Never smoke or allow a spark or flame in the vicinity of a battery or
generator.
6. Be extra cautious when working with metal tools on and around
batteries. The potential of dropping a tool causing the batteries or
other electrical parts resulting in sparks could cause an explosion.
7. Remove personal metal items such as rings, bracelets, necklaces, and
watches when working with a battery. A battery can produce a short circuit current, which is high enough to weld a ring or the like to metal
causing severe burns.
8. If a remote or automatic generator starter system is used to disable
the automatic starting circuit and/or disconnect the generator from its
starting battery while servicing to prevent accidental starting during
servicing.

1.3.1.7 Power saver Mode Setting (Switch1)
The Search Mode only activates when the unit is operating in the
inverter mode (from batteries) to prevent unnecessary battery
discharge when electrical power is not required. If the inverter is
supporting loads that must constantly be powered, please turn off
switch 1 to disable search mode.
With search mode enabled, the inverter pulses the AC output
looking for an applied load. With no load ( < 50W ) detected, the
inverter goes into the search mode to minimize energy consumption.
When a load ( > 100W ) is applied, the load current is sensed, bringing
the inverter into full power operation.

2. The Battery Charger
2.1 Theory of Operation
Inverter to Charger Transition
The internal battery charger and automatic transfer relay allow the unit
to operate as either a battery charger or inverter, but not at the same
time. An external source of AC power (e.g., shore power or generator)
must be supplied to the INVERTER's AC input in order to allow it to
operate as a battery charger. When the unit is operating as a charger,
AC loads are powered by the external source (i.e., generator or public
power).
2.2 Transfer Switching Speed
The transfer time is 1/4~1/2cycle.
3. Battery
3.1 Battery Size
Batteries are the INVERTER's fuel tank. The larger the batteries the
longer the INVERTER can operate before recharging is necessary. An
undersized battery bank results in reduced battery life and disappointing
system performance.
Batteries should not be regularly discharged to the limit of more than
50% of their capacity. Under extreme conditions, such as a severe storm
or a long utility outage, cycling to a discharge level of 80% is acceptable.
Totally discharging a battery may result in permanent damage and
reduced life.
For stand-applications, battery size should provide between 3 and 5
days of storage before needing to be recharged. The power contribution
from other charging sources is not included in this calculation to
duplicate the conditions present during a cloudy or windless period. This
is often referred to as the "number of days of autonomy." If the system is
a hybrid system with daily generator runs periods then the battery size
may be smaller. During cloudy periods the generator would be expected
to run longer. Utilities back up applications often have very small
batteries. The minimum recommended battery capacity is 200 [email protected] and 100 [email protected]
9
3.1.1 Estimating Batteries Requirement
In order to determine the proper battery bank size, it is necessary to
compute the number of amp hours that will be used during charging
cycles. When the required amp hours are known, the expected amp
hour usage ensures to be twice as this amount. Doubling the expected
amp hour usage ensures that the batteries will not be overly discharged
and extends battery life. To compute total amp hours usage, the amp
hour requirements of each appliance that is to be used is determined
and then added together.
You can compute your battery requirements using the nameplate rating
of your appliances. The critical formula is WATTS=VOLTS X AMPS.
Divide the wattage of your load by the battery voltage to determine the
amperage the load will draw from the batteries.
If the AC current is known, then the battery amperage will be as follows:
AC Current x AC Voltage / Battery Voltage = DC amps.
Multiplying the amperage by the number of hours that the load will
operate, and you have a reasonable estimate of amp hours.
Motors are normally marked with their running current rather than their
starting current. Starting current may be three to six times running
current. Manufacturer's literature may provide more accurate information
than the motor nameplate. For larger motors, increasing the battery size
indicates that the high demand for start-ups should be required.
Following this procedure for each item, you want to use with the
INVERTER. Add the resulting amp hour requirements for each load to
arrive at a total requirement. The minimum properly sized battery bank
will be approximately double this amount. This will allow the battery to
be cycled only 50% on a regular basis.
3.2 Monthly Maintenance
Checking the level of the electrolyte of each battery cell at a minimum
interval once a month after the batteries has been charged, not before. It
should be about 1/ 2" above the top of the plates, but not completely full.
Most batteries have a plastic cup that the electrolyte should just touch
when full. Don't overfill the batteries or the electrolyte will spill out of the
batteries during charging. Refill the batteries with distilled water "spring"
water and regular tap water may have high mineral levels that can only
poison the battery chemistry and reduce battery life.
10
Check the battery interconnections for tightness and corrosion. If any
corrosion is found to disconnect the cables, clean them with a mild
solution of baking soda and water. DO NOT ALLOW THE SOLUTION
TO ENTER THE BATTERY. Rinse the top of the battery with clean
water when finished. (Replace the caps first.)
To reduce the amount of corrosion on the battery terminals, coat them
with a thin layer of petroleum jelly or anti-corrosion grease available from
automotive parts stores or battery suppliers. Do not apply any material
between the terminal and the cable lugs , the connection should be
metal to metal. Apply the protective material after the bolts have been
tightened
3.3 Battery Hook-up Configurations
Battery banks of substantial size can be configured by connecting
several smaller batteries. There are three ways to do this. Batteries can
be connected in parallel, series, or series -parallel.
3.3.1 Parallel Connection
Batteries are connected in parallel when all of the positive terminals of a
group of batteries are connected, and then all of the negative terminals
of a group of batteries are connected. In a parallel configuration the
battery bank has the same voltage as a single battery and a amp/hour
rating equal to the sum of the individual batteries. This usually is done
only with 12 voltage battery -inverter systems.
11
3.3.2 Series Connection
When batteries are connected with the positive terminal of one to the
negative terminal of the next, they are connected in series. In a series
configuration the battery bank has the same amp/hour rating as a single
battery and an overall voltage equal to the sum of the individual batteries.
This is common with 24 volt or higher battery-inverter systems.
3.3.3 Series-Parallel Connection
As the name implies, both of the above techniques are used in
combination. The result is an increase in both the voltage and the
capacity of the total battery bank. This is done very often to make a
larger, higher voltage battery bank out of several smaller, lower voltage
batteries. This is common with all battery-inverter system voltages.
3.4 Battery Installation
Caution: Batteries can produce extremely high currents in short-circuit.
Be very careful working around them. Read the important safety
instructions at the beginning of this manual and the battery supplier's
precautions before installing the INVERTER and batteries.
12
3.4.1 Battery Location
Batteries should be located in an accessible location with nothing
restricting access to the battery caps and terminals. At least two feet of
clearance above is recommended. They must be located as close as
possible to the INVERTER but cannot limit access to the INVERTER
and the INVERTER's disconnect. With the SL series inverter the
batteries are best located at the left end as this is which the DC
connections are located. Do not locate the inverter in the same
compartment with non-sealed batteries (sealed batteries are acceptable).
The gasses produced by these batteries during charging are very
corrosive and will shorten the life of the inverter.
Battery to inverter cabling should be no longer than required. For 12
VDC systems do not exceed 5 feet (one way) if 4/0 AWG cables are
used. For 24 DVC systems do not exceed 10 feet (one way) if 4/0 AWG
cables are used.
3.4.2 Battery Enclosure
To prevent access from untrained personal, batteries should be
protected within a ventilated, locked enclosure or room. The enclosed
should be ventilated to the outdoors from the highest point to prevent
accumulation of hydrogen gasses that are released in the battery
charging process. An air intake should also be provided at a low point in
the enclosure to allow air to enter in order to promote good ventilation.
For most systems a one-inch diameter vent pipe from the top of the
enclosure is adequate to prevent accumulation of hydrogen. A sloped
top can help direct the hydrogen to the vent location and prevent
pockets of hydrogen from occurring. The enclosure should also be
capable of holding at least one battery cell worth of electrolyte in the
event a spill or leak occurs. The enclosure should be made of acid
resistant material or have an acid resistant finish applied to resist the
corrosion from spilled electrolyte and released fumes. If the batteries are
located out of doors the enclosure should be rainproof and have mesh
screens over any openings to prevent insects and rodents from entering.
Before placing the batteries in the enclosure cover the bottom with a
layer of baking soda to neutralize any acid that might be spilled in the
future.
13
3.4.3 Battery Cabling
Heavy cables should be used to connect individual batteries to
configure a larger battery bank. The actual size of the cable depends
upon whether the batteries are connected in parallel or series. Generally,
the cables should not be smaller than the main battery cables to the
inverter. If the main cables are 4/0 AWG the battery interconnects
should be 4/0 AWG.
It is usually preferable to connect the batteries firstly in series and then
in parallel when connecting smaller batteries. The best option is to
connect the batteries both in series and parallel in a configuration often
called "cross-trying'. This requires additional cables but reduces
imbalances in the battery and can improve the overall performance.
Consult your battery supplier for more information regarding the hook-up
configuration required for your system.
4. Installation and Operation
4.1 Installation
4.1.1 Environment
INVERTER is a sophisticated electronic device and should be treated
accordingly. When selecting the operating environment for the inverter,
do not think of it in the same terms as other equipment that works with it;
e.g., Batteries, diesel generators, motor generators, washing machines,
etc. It is a highly complex microprocessor controlled device. Generally
speaking, it is a cousin to stereo equipment, television sets, and
computers. The use of conformed coated circuit boards, plated copper
bus bars, powder coated metal components, and stainless steel
fasteners allows the unit to function in hostile environments. However, in
a condensing environment (one in which humidity and/or temperature
change causes water to form on components) all the ingredients for
electrolysis is present - water, electricity, and metals. In a condensing
environment the life expectancy of the inverter cannot be determined
and the warranty is voided.
Caution: It is in your best interest to install the INVERTER in a dry
protected location away from sources of high temperature and moisture.
Exposure to saltwater is particularly destructive and potentially
hazardous.
Locate the INVERTER as close as possible to the batteries in order to
keep the battery cables short. However, do not locate the inverter in the
same compartment as non-sealed batteries. (The INVERTER may be
14
located in a compartment with sealed electronic equipment - and
everything else. Batteries also generate hydrogen and oxygen. If
accumulated, this combination could be ignited by an arc resulting from
connection of the battery cables or by switching a relay.
Do not mount the inverter in a closed container. Unrestricted airflow is
required to operate at high power for sustained periods of time. Without
it, the protection circuitry will activate and reduce the maximum power
available.
4.1.2 System Grounding
Even system designers and electricians often misunderstand system
grounding. The subject is more easily discussed if it is divided into three
separate subjects. The grounding requirements vary in country and
application. Consult local codes and the NEC for specific requirements.
4.1.3 Equipment or Chassis Grounds
This is the simplest part of grounding. The idea is to connect the metallic
chassis of the various enclosures to have them at the same voltage level.
This reduces the potential for electric shock. It also provides a path for
fault currents to flow resulting in blown fuses or tripped circuit breakers.
The size of the connecting conductors should be coordinated with the
size of the over current devices involved. Under some circumstances the
conduit and enclosures themselves will provide the current paths.
4.1.4 Ground Electrodes / Ground Rods
There are two purposes of the grounding electrode. It called a ground
rod. The first is to "bleed" off any electrical charge that may accumulate
in the electrical system. The second is to provide a path for 'induced
electromagnetic energy' or lightning to be dissipated. The size of the
conductor to the grounding electrode or grounding system is usually
based on the size of the largest conductor in the system. Most systems
use a 5/8' (16mm) copper plated rod 6 feet (2meters) long driven in to
the earth as a grounding electrode. It is also common to use copper wire
placed in the concrete foundation of the building as a grounding system.
While either method may be acceptable, the local code will prevail.
Connection to the ground electrode should be done with special clamps
located above ground where they can be periodically inspected.
It is often desirable to use multiple ground rods in a larger system or
systems. The most common example is providing a direct path from the
solar array to earth near the location of the solar array. Most electrical
codes want to see the multiple ground rods connected by a separate
15
wire with its own set of clamps. If this is done, it is a good idea to make
the connection with a bar located outside of the conduit, if used, in a
trench. The run of buried wire may be a better grounding electrode than
the ground rods!
Well casings and water pipes can use as grounding electrodes. Under
no circumstance should a gas pipe or line be used. Consult local codes
and the NEC for more information.
4.1.5 Bonding the Grounding System to the Neutral and Negative
Conductors
This is the most confusing part of grounding. The idea is to connect one
of the current carrying conductors, usually the AC neutral and DC
negative, to the grounding system. This connection is why we call one of
the wires "neutral" in the North American type of electrical systems. You
can touch this wire and the grounding system and not receive a shock.
When the other ungrounded conductor, the hot or positive, touches the
grounding system, current will flow through it to the point of connection
to the grounded conductor and back to the source. This will cause the
over current protection to shop the flow of current, protecting the system.
The point of connection between the grounding system and the current
carrying conductor is often called a "bond." It is usually located in the
over current protection devices' enclosure. Although the point of
connection can be done at the inverter, codes do not generally allow it
since the inverter is considered a "serviceable” item which may be
removed from the system. In residential systems the point of connection
is located at the service entrance panel. After the power has passed
through the kilowatt hour meter of the utility.
In some countries the neutral is not bonded to the grounding system.
This means you may not know when a fault has occurred since the over
current device will not tip unless a "double" fault occurs. This type of
system is used in some marine electrical codes.
Bonding must be done at only one point in an electrical system. Our
systems inherently have two separate electric systems- a DC system
and a AC system. This means that two bonding points will occur in all
inverter applications. The bonding point will also be connected to the
chassis ground conductors. It is common to have two separate
conductors connect the ground electrode and the two bonding points.
Each conductor should use a separate clamp.

4.3 Installation Steps
● Step 1
Wire the unit from the battery to the utility power source, and then to the
AC load. Confirm all wiring is correct and terminal is tight.
● Step 2
Check all the voltage rating is correct. Turn on the circuit breaker.
● Step 3
Press the on/off button. The system will start working after a few
seconds. If the utility power fails the unit will work in Inverter mode. If not,
the system will switch to charging mode and deliver energy to load and
battery.

6. Troubleshooting
1.
A small size battery being charged with a higher charging rate could
cause an over voltage shut down or begin charging an already
charged battery. Both could cause an over voltage shut down. Please
reduce the charge rate or discharge the battery before recharging.
2. If system does not turn on properly turn off the Breaker in the front of
the DC side, disconnect the system from battery for 30 seconds, and
then repeat the turn on steps. If the system still does not function
please contact your dealer.
7. Service and Support
If you have any questions or problems with the UPS, call your Local
Distributor to ask for a technical representative.
Please have the following information ready when you call the Local
Distributor:
● Model number
● Serial number
● Date of failure or problem
● Symptoms of failure or problem
● Customer returns address and contact information
If repair is required, you will be given a Returned Material Authorization
(RMA) Number. This number must appear on the outside of the package
and on the Bill of Lading (if applicable). Use the original packaging or
request packaging from the Help Desk or distributor. Units damaged in
shipment as a result of improper packaging are not covered under
warranty. A replacement or repair unit will be shipped, freight prepaid for all
warranted units.
