  • CHG: Green (Solid On: Battery is fully charged; Flashing: Battery is charging)
  • FAULT: Red (Solid On: Fault occurs in the inverter; Flashing: Warning condition occurs in the inverter)

Function Buttons

  • ESC: To exit setting mode
  • UP: To go to previous selection
  • DOWN: To go to next selection
  • ENTER: To confirm the selection in setting mode or enter setting mode

Trouble Shooting

This section provides solutions for common problems such as unit shutdown during startup, no response after power on, mains issues, battery disconnections, fan faults, over-temperature, over-charged battery, low battery voltage/SOC, output short circuit, abnormal inverter voltage, overload, bus voltage issues, internal component failures, communication errors, and parallel system issues.

Troubleshooting and error codes

Problem LCD/LED/Buzzer Explanation What to do
Unit shuts down Automatically during startup process. LCD/LEDs and buzzer will be active for 3 seconds and then complete off. The battery voltage is too low (<1.91V/Cell) 1. Re-charge battery. 2. Replace battery.
No response after power on. No indication. 1.The battery voltage is far too low. (<1.4V/Cell)
2.Battery polarity is connected reversed.		 1. Check if batteries and the wiring are connected well.
2. Re-charge battery.
3. Replace battery.
Mains exist but the unit works in battery mode. Input voltage is 0 on the LCD and green LED is flashing. Input protector is tripped. Check if AC breaker is tripped and AC wiring is connected well.
Green LED is flashing. Insufficient quality of AC power (Shore or Generator) 1. Check if AC wires are too thin and/or too long.
2. Check if generator (if applied) is working well or if input voltage range setting is correct. (UPS Appliance)
When it's turned on, internal relay is switching on and off repeatedly. LCD display and LEDs flashing Battery is disconnected. Check if battery wires are connected well.
Buzzer beeps continuously and red LED is on. (Fault code) Fault code 01 Fan fault. 1.Check whether all fans are working properly.
2.Replace the fan.
Fault code 02 Internal temperature of component is over 100°C. 1. Check whether the air flow of the unit is blocked or whether the ambient temperature is too high.
2. Check whether the thermistor plug is loose.
Fault code 03 Battery is over-charged. Restart the unit, if the error happens again, please return to repair center.
Buzzer beeps once every second, and red LED is flashing. (Warning code) Warning code 04 The battery voltage/SOC is too low. 1. Measure battery voltage in DC input.
2. Check battery SOC in LCD when use Li battery.
3. Recharge the battery.
Fault code 05 Output short circuited. Check if wiring is connected well and remove abnormal load.
Fault code 06/58 Output abnormal (Inverter voltage is higher than 280Vac or lower than 80Vac). 1. Reduce the connected load.
2. Restart the unit, if the error happens again, please return to repair center.
Fault code 07 The inverter is overload 110% and time is up. Reduce the connected load by switching off some equipment.
Fault code 08 Bus voltage is too high. 1. If you connect to a lithum battery without communication, check whether the voltage points of the program 19 and 21 are too high for the lithum battery.
2. Restart the unit, if the error happens again, please return to repair center.
Fault code 09/53/57 Internal components failed. Restart the unit, if the error happens again, please return to repair center.
Warning code 15 The input status is different in parallel system. Check if AC input wires of all inverters are connected well.
Warning code 16 Input phase is not correct. Change the input phase S and T wiring.
Warning code 17 The output phase not correct in parallel. 1.Make sure the parallel setting are the same system(sigle or paralle; 3P1,3P2,3P3).
2.Make sure all phases inverters are power on.
Warning code 20 Li battery can't communicate to the inverter. 1. Check whether communication line is correct connection between inverter and battery.
2. Check whether BMS protocol type is correct setting.
Fault code 51 Over current or surge. Restart the unit, if the error happens again, please return to repair center.
Fault code 52 Bus voltage is too low. Restart the unit, if the error happens again, please return to repair center.
Fault code 55 Output voltage is unbalanced 1. If you connect to a lithum battery without communication, check whether the voltage points of the program 19 and 21 are too high for the lithium battery.
2. If the battery is connected well, restart the unit. If the error happens again, please return to repair center.
Fault code 56 Battery is not connected well or fuse is burnt. 1. Check whether the AC output connected to the grid input.
2. Check whether Program 8 settings are the same for all parallel inverters
3. Check whether the current sharing cables are connected well in the same parallel phases.
4. Check whether all neutral wires of all parallel units are connected together.
5. If problem still exists, contact repair center.
Fault code 60 Negative power fault 1. Check whether the parallel communication cables are connected well.
2. Check whether Program 23 settings are right for the parallel system.
3. If problem still exists, contact repair center
Fault code 80 CAN fault 1. Check whether the parallel communication cables are connected well.
2. Check whether Program 23 settings are right for the parallel system.
3. If problem still exists, contact repair center
Fault code 81 Host loss 1. Check whether the parallel communication cables are connected well.
2. Check whether Program 23 settings are right for the parallel system.
3. If problem still exists, contact repair center
