6 Troubleshooting and maintenance
6.1 Troubleshooting
This part introduces the common faults and solving steps, provides troubleshooting
method and skills to the user, and helps the user identify and solve some common fault
of the inverter.
Faults mentioned in this part means the inverter enters the
protection state or fault state.
The protection state is mostly caused by some external reasons, e.g.: the DC voltage is too
high, the inverter output is not matched with the grid, the grid is power off or the system
is not correctly earthed, and thus the inverter acts to ensure the own safety. The inverter
itself has no defect and can be recovered from the protection state if the system is correctly
designed and installed.
Sometimes the inverter enters the protection state by the own defect and can be recovered
by resetting or repairing.
The fault state is caused by the own defect of the inverter, and thus the inverter acts to
protect the system safety. The inverter can be recovered from some faults automatically
or by resetting, and some faults are caused by the own defect of the inverter, and in this
case the inverter cannot be recovered and shall be repaired.
Correctly identifying the fault state of the inverter is helpful for solving the fault, so please
treat as per the following steps:
1) Check if the state displayed on the panel is a protection state or fault state, and record
all error codes;
2) Try the solution listed in Tab. 6-1 and 6-2 and meanwhile check as per the following steps;
If the voltage at the AC/DC side is normal and if the breaker is opened?
If the inverter is installed in a clean, dry and well ventilated place?
If the cable sectional area satisfies the requirement?
If the connecting cable is too long?
If all cables are firmly connected?
If wiring is reasonable?
If the safety standard setting is correct?
3) If you meet any problem that you cannot solve it by yourself, please contact the client
service man of Victory Power For the optimal solution, please provide use the detailed
system installation information, inverter model, serial number and fault information.
