F35 No AC grid
No Utility
1. Please confirm grid is lost or not;
2. Check the grid connection is good or not;
3. Check the switch between inverter and grid is on or not;
4. Seek help from us, if can not go back to normal state.
F41 Parallel system stop
1. Check the hybrid inverter working status. If there's 1 pcs
hybrid inverter is in OFF status, the other hybrid inverters
may report F41 fault in parallel system.
2. If the fault still exists, please contact us for help.
F42 AC line low voltage
F47 AC over frequency
Grid voltage fault
1. Check the AC voltage is in the range of standard voltage in
specification;
2. Check whether grid AC cables are firmly and correctly
connected;
3. Seek help from us, if can not go back to normal state.
Grid frequency out of range
1. Check the frequency is in the range of specification or not;
2. Check whether AC cables are firmly and correctly connected;
3. Seek help from us, if can not go back to normal state.
F48 AC lower frequency
Grid frequency out of range
1. Check the frequency is in the range of specification or not;
2. Check whether AC cables are firmly and correctly connected;
3. Seek help from us, if can not go back to normal state.
F56
DC busbar voltage is
too low
Battery voltage low
1. Check whether battery voltage is too low;
2. If the battery voltage is too low, using PV or grid to charge the
battery;
3. Seek help from us, if can not go back to normal state.
F58 BMS communication fault
1. it tells the communication between hybrid inverter and battery
BMS disconnected when"BMS_Err-Stop" is active;
2. if don’t want to see this happen, you can disable
"BMS_Err-Stop" item on the LCD;
3. If the fault still exists, please contact us for help.
F63 ARC fault
F64
Heat sink high temperature
failure
1. ARC fault detection is only for US market;
2. Check PV module cable connection and clear the fault;
3. Seek help from us, if can not go back to normal state.
Heat sink temperature is too high
1. Check whether the work environment temperature is too high;
2. Turn off the inverter for 10mins and restart;
3. Seek help from us, if can not go back to normal state.

F34 AC Overcurrent fault
1. Check the backup load connected, make sure it is in allowed
power range;
2. If the fault still exists, please contact us for help.
