54 V00 Installation and operating instructions
Fault
36
Ground Fault
The residual current exceeds the permitted
upper limit.
37
PV Overvoltage
The voltage of the strings exceeds the
permitted upper limit.
38
ISO Fault
The PV generator’s insulation resistance to
earth is below the permitted value, or the
electrical insulation inside the inverter has
failed.
39
Fan Lock
The fan or internal circuit 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
Ground I 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.
46
High DC Bus

permitted upper limit.
49
PV1-SPD failure
PV1-SPD failure
50
PV1-SPD failure
PV2-SPD failure
51
FUSE failure
DC side FUSE failure
The latest 10 dated failure reports on the NS protection can be read. An interruption
in the supply voltage of ≤ 3s does not result in any loss of failure reports (according
to VDE-AR-N 4105).
