1，The BUS voltage can t be built from PV or battery.
2，Restart the inverter, If the fault still exists, please
contact us for help
F01
DC_Inversed_Failure
1，Check the PV input polarity
2，Seek help from us, if can not go back to normal state.
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 it remains same, turn on DC and AC switch for one minute,
then turn on the DC and AC switch.;
6. Seek help from us, if can not go back to normal state.
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 normal;
3. Seek help from us, if can not go back to normal state.
Leakage current fault
1, Check the PV side cable ground connection
2, Restart the system 2-3 times
3, if the fault still existing, please contact us for help.
AC side over current fault
1. Please check whether the backup load power and
commonload power are within the range;
2. Restart and check whether it is normal;
3. Seek help from us, if cannot go back to normal state.
DC side over current fault
1. Check PV module connection and battery connection;
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. If it remains same, turn on DC and AC switch for one minute,
then turn on the DC and AC switch.;
4. Seek help from us, if can not go back to normal state.
