5.3 BATTERY REQUIREMENTS
Battery type and battery size strongly affect the performance of the power inverter.
Therefore, you need to identify the type of loads your inverter will be powering and how
much you will be using them between charges. Once you know how much power your
need. We recommend that you purchase as much battery capacity as possible.
5.4 CHARGING SYSTEM:
The charging system must be appropriate for your particular installation. A well-designed
charging system will ensure that power is available when you need it and that your
batteries remain in top condition. Inadequate charging degraded system performance
and the wrong type of charger will reduce battery life.
Contact us or visit our website to find more information about our different battery
chargers.
The power inverter must only be installed in a location that is:
DRY The inverter must be installed in a dry location not subject to moisture especially
rain, spray, or splashing bilge water.
COOL The inverter should not be exposed to metal fillings or any other form of
contamination.
VENTILATION The ambient air temperature should be between 0-40 ℃ (32-104 F) for best
performance.

SAFE
mounted in a tight fitting compartment, the compartment must be ventilated with cut-
outs to prevent the inverter from overheating.
CLOSE TO BATTERY The inverter is not ignition-protected equipment, so it cannot be
installed in areas containing gasoline tanks or fittings which require ignition - protected
equipment. We recommend that it is safest not to install any kind of electrical equipment
including the inverter in these areas.
PROTECTED FROM BATTERY GASES The inverter should be installed as close as possible to
the batteries, but not in the same compartment to prevent corrosion. Avoid excessive
cable lengths and use the recommended wire sizes. We recommend that installing with
battery cables sized to achieve less that 3% voltage drop on battery cables under full load.
This will maximize the performance of the inverter.
To operate safely and effectively, use low - resistance wiring between the battery and the
inverter because the inverter receives high-current input from a low-voltage battery.
Run a chassis ground cable from the grounding point to chassis ground screw on the
inverter s DC panel.
There is spare DC cable inside of packing, you can use it for normal connection, if you need
longer or special system installation, when purchasing cables for DC input and ground:
Use the enough size DC input cable if you use longer cable.
Use a matching cable size for ground cable. Terminate one end with an appropriately
sized ring connector.
Use standard copper wires, avoiding aluminum wires due to their higher-resistance
rating. Have your DC input cables crimped and terminated with appropriately sized ring
connectors at the store of purchase.
Ventilation openings on the inverter must not be obstructed. If the inverter is
7. CABLES FOR DC INPUT AND GROUND
8. FUSES OR CIRCUIT BREAKER
For safety concern, you can connect a DC-rated fuse or a DC rated circuit breakers on the
positive cable line in your power system, following these recommendations when you
purchasing fuses or circuit breakers.
Select a fuse or circuit breaker with a maximum rating of 150Adc.
Determine the short-circuit current rating of the battery and choose a battery fuses that
withstand the short circuit current that may be generated by the battery.

This section explains how to operate the inverter efficiently and effectively:
Gives procedures for operating the inverter from the front panel
Discusses operating limits and inverter loads
Discusses battery charging frequency
Provides information about routine maintenance
Note: The inverter's output power efficiency is different when input voltage is different.
10.1 TURNING THE INVERTER ON AND OFF
The ON/OFF switch on the inverter s front panel is the main ON/OFF switch that turns the
control circuit in the inverter on and off.
To turn the inverter on and off from its front panel:
Move the ON/OFF switch to the ON position to turn the inverter on.
Move the ON/OFF switch to the OFF position to turn the inverter off.
When switch is off, the inverter draws a very low current from the battery.
To turn the inverter on and off from the remote switch:
Make sure the main ON/OFF switch on the front panel is turned ON.
Move the remote ON/OFF switch to the ON position to turn the inverter ON.
Move the remote ON/OFF switch to the OFF position to turn the inverter OFF.
When the remote switch is off, the inverter draws a very low current from the battery.
The inverter draws a current from the battery with the main ON/OFF switch turned
on and no load connected. If the main switch is left on, even with no loads the inverter will
eventually discharge the battery. To prevent unnecessary battery discharge, turn the
inverter off when you are not using it.
10. INVERTER OPERATION
ELECTRICAL SHOCK HAZARD
The inverter's ON/OFF switch does not disconnect DC battery power from the inverter. You must disconnect
AC and DC power before working on any circuits connected to the inverter.
Failure to follow these instructions can result in death or serious injury.

switch, use it to select one

10.2 THE OUTLETS (THE TYPE OPTIONAL) INSTALLED ON INVERTER AS FOLLOWS:
10.2.1 Testing the GFCI (if you choose the inverter with GFCI outlet) Perform the following
GFCI test:
1. Turn the inverter on.
2. Plug a simple appliance, such as a lamp, in the GFCI outlet. Turn the lamp on.
3. Press the TEST button. Observe a clicking sound. The lamp turns off.
4. Press the RESET button all the way to the bottom until the button locks unto position.
The lamp turns back on.
IMPORTANT: Perform this GFCI test once a month to ensure continued functionality of the
GFCI.
If you are going to operate several loads from the inverter, turn the loads on one at a time
after you have turned the inverter on.
Turning loads on separately helps to ensure that the inverter does not have to deliver the
starting current fro all the loads at once, and will help prevent an overload shutdown.
Power output the inverter can deliver the power (in watts) same as the labeled in inverter
continuous (e.g. The label indicate 1500Watts continuous in 1500w inverter), the wattage
rating.
Applies to resistive loads such as incandescent lights.

12. INVERTER LOADS
The inverter will operate most AC loads within its power rating. However, some
appliances and equipment may be difficult to operate, and other appliances may actually
be damaged if you try to operate then with the inverter. Please read high surge loads and
trouble loads carefully.
Some induction motors used in freezers, pumps, and other motor-operated equipment
require high surge currents to start. The inverter may not be able to start some of these
motors even though their rated current draw is within the inverter s limits. The inverter
will normally start single-phase induction motors.
Some equipment may be not work well or damaged by the inverter s modified sine wave
output.
Some appliances, including the types listed below, may be not work well or damaged if
they are connected to the inverter:
Electronics that modulate RF (radio frequency) signals on the AC line will not work well or
may be damaged.
Speed controllers found in some fans, power tools, kitchen appliances, and other loads
may be not working fine.
Some chargers for small rechargeable batteries
Metal halide arc (HMI) lights If you are unsure about powering any device with the
inverter, contact the manufacturer of the device.
Connecting Appliances to the inverter since regular amounts of AC current flows between
the inverter and your appliances, commonly available extension cords can be used to
connect the inverter to your appliances. If your appliances will be connected at a
considerable distance from the inverter, it is much more practical and less expensive to
lengthen the AC wiring than it is to lengthen the DC wiring.
13.1 Maintaining the inverter minimal maintenance is required to keep your inverter
operating properly, periodically you should:
Clean the exterior of the unit with a damp cloth to prevent the accumulation of dust
and dirt.
Ensure that DC cables are secure and fasteners are tight.
Make sure the ventilation openings on the DC panel and bottom of the inverter are not
clogged
13. ROUTINE MAINTENANCE
the inverter shuts down to protect itself
from excessive input voltage (note:
although the inverter incorporates over
voltage protection, it can still be damaged if
input voltage exceeds 16 volts.
the inverter shutdown to protect the
battery from being over-discharged

When possible, recharge your batteries when they about 50% discharged or earlier. This
gives the batteries a much longer life cycle than recharging when they are more deeply
discharged.
Our inverter has a battery low voltage shutdown around 20Vdc.With moderate to heavy
loads, this will protect against over-discharging the battery. if the inverter is running only
light loads it is advisable to recharge before the inverter low voltage shutdown point is
reached.
For more information on maintaining batteries, consult your battery's manufacturer.
For information about our battery chargers, please contact us.
The battery s back up time depends on the battery capacity(Ah)and your appliances
power (Watt)
The method to calculate the operation time is :
Battery capacity(Ah) x input back up / loads power(W)
For example:
Battery capacity= 150Ah
Input Voltage= 12V
Loading power= 600W
(150Ah x 12V)/600W= 3H
This section describes the most common problems you may encounter with the operation
of the inverter along with resolutions.
If you encounter problems other than what is described in this section, contact customer
supporting center.
16.1 COMMON PROBLEMS
16.1.1 Buzz in Audio Equipment
Some inexpensive stereo systems may emit a buzzing noise from their loudspeakers when
operated from the inverter. This occurs because the power supply in the audio System
does not adequately filter the modified sine wave produced by the inverter.
The only solution is to use a sound system that has a high quality power supply.
16.1.2 Television Reception
