08

Output voltage is too high

Restart the unit; if error persists, return to repair center.

09

Output short circuited

Check if wiring is connected well and remove abnormal load.

10

Overload time out

Reduce the connected load by switching off some equipment.

11

Battery voltage is too high

Check if spec and quantity of batteries meet requirements.

12

Over current happen at DCDC circuit

Restart the unit; if error persists, return to repair center.

Check if wiring is connected well.

15

PV power is abnormal

Reduce the number of PV modules.

16

Over current happen at PV port

Restart the unit; if error persists, return to repair center.

17

Fan is locked

Check if wiring is connected well. Replace the fan.

18

Over temperature happen at PV circuit

Check if air flow is blocked or ambient temperature is too high.

19

Over temperature happen at battery circuit

Check if air flow is blocked or ambient temperature is too high.

20

Over temperature happen at inverter circuit

Check if air flow is blocked or ambient temperature is too high.

21

The inner temperature over

Check if air flow is blocked or ambient temperature is too high.

22

Check wiring connection; for parallel installation, ensure correct connection and restart inverters.

29

DC/DC soft start fail

Restart the unit; if error persists, return to repair center.

30

CAN data loss

Check communication cables and restart the inverter.

31

Host data loss

Check communication cables and restart the inverter.

32

Synchronization data loss

Restart the inverter.

33

Current feedback into the inverter is detected

Check if L/N cables are connected reversely; ensure proper sharing cables and phase system.

34

The firmware version is not the same

Update all inverter firmware to the same version; check LCD setting and CPU firmware.

35

The output current of each inverter is different

Check sharing cables and restart the inverter.

36

AC output mode setting is different

Switch off inverter, check LCD setting (program 28), ensure consistent three-phase settings.
