Solutions
F07
DC_START_Failure
F13
working mode change
F15
AC over current fault of
software
F16
AC leakage current fault
F18
AC over current fault
of hardware
F20
DC over current fault ofthe
hardware
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 input polarity reverse fault
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 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.
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.
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 in normal;
3. Seek help from us, if cannot 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.
