Tz_EmergStop_Fault
F24
DC insulation impedance
failure
F26
The DC busbar is
unbalanced
F29 Parallel CANBus fault
1. When the grid type and frequency changed it will report F13;
2. When the battery mode was changed to “No battery” mode,
it will report F13;
3. For some old FW version, it will report F13 when the system
work mode changed;
4, Generally, it will disappear automatically when shows F13;
5. 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;
6. Seek help from us, if can not go back to normal state.
F08 GFDI _Relay_Failure
1. When inverter is in Split phase(120/240Vac) or three-phase
system (120/208Vac) system, the backup load port N line
needs to connect ground;
2. If the fault still exists, please contact us for help.
AC side over current fault
1. Please check whether the backup load power and common
load power are within the range;
2. Restart and check whether it is in normal;
3. Seek help from us, if can not go back to normal state.
DC side over current fault
1. Check PV module connect and battery connect;
2. When in the off-grid mode, the inverter startup with big power
load, it may report F20. Please reduce the load power connected;
3. Turn off the DC switch and AC switch and then wait one
minute,then turn on the DC/AC switch again;
4. Seek help from us, if can not go back to normal state.
Leakage current fault
1. Check PV side cable ground connection.
2. Restart the system 2~3 times.
3. If the fault still exists, please contact us for help.
Please contact your installer for help.
PV isolation resistance is too low
1. Check the connection of PV panels and inverter is firmly and
correctly;
2. Check whether the PE cable of inverter is connected to ground;
3. Seek help from us, if can not go back to normal state.
1. Please wait for a while and check whether it is normal;
2. When the hybrid in split phase mode, and the load of L1 and
load of L2 is big different, it will report the F26.
3. Restart the system 2~3 times.
4. Seek help from us, if can not go back to normal state.
1. When in parallel mode, check the parallel communication cable
connection and hybrid inverter communication address setting;
2. During the parallel system startup period, inverters will report F29.
when all inverters are in ON status, it will disappear automatically;
3. If the fault still exists, please contact us for help.
