10.1 Error code
In the case of failure the LCD screen will display an alarm message. In this case the inverter
may stop feeding energy into the grid. The alarm description and their corresponding
alarm messages are listed Table 9.1.
Error code Description Solutions
F10
Auxiliary switch power supply
failure
F13 Reserved
F16
GFCI(RCD) Ac leakage
current fault
F20
DC over current fault of the
hardware
F23
AC leakage current is transient
over current
F24
DC insulation impedance
failure
1. Turn off DC/AC switch, and turn on DC/AC switch 10mins
later;
2. If the fault still exists, please contact us for help.
1. Loss of one phase or AC voltage detection part failure or relays
not closed;
2. Seek help from us, if can't go back to normal state.
F15 AC firmware over current
1. Restart inverter and check whether it is in normal;
2. Seek help from us, if can't go back to normal state.
1. Check PV module connection;
2. Turn off the DC/AC switch and then wait 1~2 minute, then
turn on the DC/AC switch again;
3. Seek help from us, if can't go back to normal state.
1. Check DC input power is within the allowed range;
2. Restart inverter and check whether it is in normal;
3. Seek help from us, if can't go back to normal state.
F18
AC over current fault of
hardware
1. Restart inverter and check whether it is in normal;
2. Seek help from us, if can't go back to normal state.
1. Please wait for a while and check whether it is normal;
2. If still same, and turn off the DC switch and AC switch and
wait for one minute and then turn on the DC/AC switch;
3. Seek help from us, if can't go back to normal state.
1. Check PV panels connection and restart inverter. This
problem is caused by the PV side usually;
2. If the fault still exists, please contact us for help.
F30 AC main contactor failure
1. Turn off the DC/AC switch and then wait 1~2 minutes, then
turn on the DC/AC switch again;
2. If the fault still exists, please contact us for help.
F39
AC over current (one cycle)
Grid voltage fault
1. Wait for inverter to return to normal;
2. Disconnect DC switch and AC switch, and reconnect DC
switch and AC switch 10min later to restart the inverter;
3. If the fault still exists, please contact us for help.
F35 No AC grid
1. Check AC grid voltage;
2. Check whether the AC output connection is in good
condition;
3. If the fault still exists, please contact us for help.
