Error Code Description Solutions
F29 Parallel_Comm_Fault
1. When in parallel mode, check the parallel communication
cable connection and hybrid communication address set-
tings.
2. During the parallel system startup period, inverters will re-
port F29. When all inverters are in ON status, it will disappear
automatically;
3. If the fault exists, please contact us for help.
F34 AC_Overload_Fault
1. Check the backup load connected, make sure it is in al-
lowed power range;
2. If the fault still exists, please contact up for help.
F41 Parallel_system_Stop
1. Check the hybrid inverter working status. If there's 1pcs
hybrid inverter is in OFF status, the other hybrid inverters
may report F41 fault in parallel system.
2. If the fault exists, please contact us for help.
F42 Parallel_Version_Fault
Grid voltage fault
1.Check if the voltage is in the range of standard voltage in
specication this can be adjusted via the grid set up page.
2.Check if grid cables are correctly connected.
F47 AC_OverFreq_Fault
Grid frequency out of range
1.Check if the frequency is in the range of specication
2.You may need to adjust the frequency on the grid set up
page.
F48 AC_UnderFreq_Fault
Grid frequency out of range
1. Check the frequency is in the range of specication or not.
2. Check whether AC cables are rmly and correctly connect-
ed.
3. Seek help from us, if can not go back to normal state.
F52 DC_VoltHigh_Fault
BUS voltage is too high
1. Check whether battery voltage is too high;
2. Check the PV input voltage, make sure it is within the
allowed range;
3. Seek help from us, if can not go back to normal state.
F53 DC_VoltLow_Fault
BUS voltage is too 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.
F54 BAT2_VoltHigh_Fault
1. Check the battery 2 terminal voltage is high;
2. Restart the inverter 2 times and restore the factory set-
tings;
3. Seek help from us, if can not go back to normal state.
