Zeversolar Inverter Error Codes.

Zeversolar Inverters have several error codes that you may encounter when installing the system or during the life time of operation  the error codes are.

1 SCI Fault Communication between the master and slave CPU has failed.
2 EEPROM R/W Fault Reading or writing of EEPROM has failed.
3 Rly-Check Fault Output relay has failed.
4 DC INJ. High Output DC feed-in exceeds the permitted upper limit.
6 High DC Bus The voltage of DC bus exceeds the permitted upper limit.
8 AC HCT Fault Output current is abnormal
9 GFCI Fault Ground fault detection circuit is abnormal
10 Device Fault Unknown Error
33 Fac Fault The grid frequency is outside the permitted range.
34 Vac Fault The grid voltage is outside the permitted range.
35 No Utility Grid Available The utility cannot be detected, which may be caused by no utility, grid disconnected, AC cables damaged, fuse broken or island mode.
36 Residual current fault The residual current exceeds the permitted upper limit.
37 PV Overvoltage The voltage of the PV strings exceeds the permitted upper limit.
38 ISO Fault The PV array’s insulation resistance to ground is below the permitted value, or the electrical insulation inside the inverter has failed.
40 Over Temp. The internal temperature exceeds the permitted value.
41 Vac differs for M-S A different value of grid voltage has been detected by the master and slave MCU.
42 Fac differs for M-S A different value of grid frequency has been detected by the master and slave MCU.
43 Residual current differs for M-S A different value of residual current has been detected by the master and slave MCU.
44 DC Inj. differs for M-S A different value of DC feed-in has been detected by the master and slave MCU.
45 Fac,Vac differs for M-S Different values of grid frequency and voltage has been detected by the master and slave MCU.
