4.3 Mode Switch
of the inverter flexibly according to the demand
SAV/NOR: NOR is normal output mode, standby power<8W; SAV is power saving mode,
standby power<5W. When the switch is on "SAV" side, the inverter will enter into the
Saving Mode. It will shut off the output if the output power is less than 20W. Then
restart and detect the power of the load again after 10s. If the load is more than 20W,
the inverter will turn on the output. Otherwise it will shut off output again. It cycles like
this. So please don't use the saving mode if the load is smaller than 20W.
50/60Hz: Output frequency is adjustable.
220/230Vac(or110/120Vac): Output voltage is adjustable.
The output voltage, power and frequency can be modified .
!Ventilation fan: When the temperature of the radiator is greater than 40 ℃, the fan will be turned on;
otherwise, the fan will be turned off.

CAUTION: Please read the manual carefully to get familiar with the installation steps
before installation.
6.1 Installation Notes
③
②
①Be very careful when installing the batteries, especially flooded lead-acid batteries. Please wear eye
protection, and have fresh water available to rinse if any contact with battery acid.
Keep the battery away from any metal objects, which may cause a short circuit of the battery.
Loose connections and corroded wires may result in high heat that can melt wire insulation, burn
surrounding materials, or even cause a fire. Ensure tight connections and use cable clamps to secure cables
and prevent them from swaying in motion.
④Select the system connection cables according to the current density no higher than 3.5A/mm2.
⑤For outdoor installation, keep out of the direct sunshine and rain infiltration.
⑥Please do not install the inverter in humid, greasy, flammable, explosive, dust accumulative, or other
severe environments.
⑦AC output is a high voltage, and please do not touch the wiring connection.
⑧When the fan is working, and please do not touch it to avoid injury.
CAUTION: To avoid the danger of heat accumulation caused by the loose
connection, please ensure all the cable connections are tight.
WARNING: Make sure the inverter is clean and no electrical connection before
installation.
CAUTION: Please connect the inverter case to the ground and ensure the
sectional area of the connection cable is not less than 4mm²。
CAUTION: Follow the parameter setting requirements to set the DC input
voltage, higher or lower may cause the inverter down or even broken.
CAUTION: The cable between battery and inverter should be less than 3meters,
otherwise, please reduce the current density.
CAUTION: A fuse or breaker is recommended between battery and inverter,
also the rated current of the fuse or breaker should be 1.25*Rated current of battery.
CAUTION: Keep the inverter away from the flooded lead-acid battery because
the sparkle of the terminals may ignite the hydrogen released by the battery.
WARNING：Do not directly connect the battery charger or similar devices to
the input terminal of the inverter.
WARNING: Only the load is allowed to connect to the AC output terminal, do
not connect it to power supply or utility, which may cause the inverter
damaged, also please shut off the inverter before wiring.

6.2 Mounting Location Requirements
Do not subject the inverter to direct sunlight or any other heat sources. Protect the inverter from any dust,
dirt and moisture. Mount it flat to a vertical wall. Must be a non-flammable material. Maintain a minimum
clearance of 15 cm below and around the inverter to ensure unhindered air circulation.

CAUTION: 1.The switch of the inverter is OFF before wiring.
2.Do not close the circuit breaker or fuse and make sure that the leads of “+” and“-”
poles are correctly connected while wiring the inverter.
WARNING：The AC equipment shall be determined by the continuous output power of the
inverter, but the surge power must be lower than the instantaneous surge power of the inverter.
CAUTION: A fuse which current is 12.5*Select the maximum battery current, it must be installed
on the battery side with a distance from the battery not greater than 150mm.

Please confirm that the inverter is off before wiring.
Switch on the input breaker or the fuse between inverter and battery;
3) Turn on the power switch to start the inverter, Green indicator on solid, and the AC output is normal;
4) Turn on the load one by one, and check the operation status of both inverter and load;
5) If the fault indicator is red and the buzzer alarms when turn on the inverter, please switch off the loads
and inverter immediately. Refer to 8.2 Troubleshooting. After troubleshooting, please follow the above steps
and operate again.
1st step: Grounding: Connect the ground terminal of the inverter to the ground
2nd step: Loads: Connect the load to the inverter output (universal socket).
3rd step: Battery
Connect the battery cables observing the correct polarity to the input terminal of the Inverter(make sure
you identify the battery marking/symbol on the inverter casing!) . Pay greatest attention to polarity. Never,
ever invert the plus+ and minus- poles).
4th step: Power on the inverter
1) Tighten all cables connected to the inverter and remove all the remains around the inverter (leaving a
void of minimum 15 cm);

8, Troubleshooting, Protections and maintenance
Input reverse polarity protection
It is recommended that the battery be connected in series with fuse(60A) prevent the internal
components of inverter from being damaged.
Over voltage protection
When the input voltage exceeds 16/31V, the inverter will stop charging to protect the battery from
overcharging damage. When the voltage is reduced to 14.5/29V, it will resume normal operation.
Low voltage protection
When the input voltage is lower than 10.8/21V, the inverter will stop discharging to protect the battery from
over discharging damage. When the voltage rises above 12.5/25V, it resumes working.
Load Short circuit Protection
Once the load short circuit happens, the load short circuit protection will trigger automatically. (When
the overload protection happens, the AC output will recover automatically for 3 times(recover after 5s).
After then the AC output will not recover automatically after 3 times attempt until restarting the
inverter.)
Overload protection
Once the output power is higher than rated power, the over load protection will trigger automatically.
(When the overload protection happens, the AC output will recover automatically for 3 times(recover
after 5s). After then the AC output will not recover automatically after 3 times attempt until restarting
the inverter.)
Over Temperature Protection
The inverter detects the internal temperature through internal sensor, when the temperature exceeds
95℃, it will stop working and resume after temperature returns to 70℃.
8.1 Protection
!When the overload protection happens 4 times, the AC output do not have the recover
automatically function.

WARNING: Do not try to repair or maintain the inverter by own, and it may
cause danger.

Improve ventilation quality, do not block the vent, reduce
the temperature around the power supply, restart the
device after the temperature reaches 70℃, if still not
working, please derate the power for use.
Check if the load exceeds the rated output power of the
inverter.
Check that if the output is overloaded, if the output line is
shorted, or if the dial switch is SAV mode. Clear the fault
and restart the inverter to resume normal operation.

For best system performance, the following inspections and maintenance tasks are recommended to be
carried out for at least two times a year.
Make sure no block on air-flow around the inverter. Clear up any dirt and fragments on radiator.
Check all the naked wires to make sure insulation is not damaged. Repair or replace some wires if
necessary.
Check and confirm that LED is consistent with required. Pay attention to any troubleshooting or error
indication. Take corrective action if necessary.
Make sure all system components are effectively and tightly connected to ground.
Check all terminals for any corrosion signs, damaged insulation, increased temperature or
carbonization/discolored signs.
Check for any dirt and any corrosion signs. Implement corrections actions as early as possible.
WARNING：Risk of electric shock!
Make sure that all the power has been turned off and standing still for 20
minutes before above operations, and then follow the corresponding inspections
and operations.
