Errors 017 to 019
· AFI fault current
The error «AFI fault current» occurs if fault
current has penetrated the PV system and
the Solar Inverter has subsequently discon-
nected from the grid. The earth fault is
monitored on the AC and on the DC side
(universal current sensitive FI). If this error
message occurs, the entire PV system must
be checked for insulation faults. The func-
tioning method complies with E DIN VDE
0126-1-1. In case of fault current at inlet 1
of the PV generator, for example, «error
017» will be flagged.
Errors 020 to 022
· Insulation faults
Prior to start-up, your Solar Inverter always
checks the PV system for an earth fault or
an insulation fault. Should such a fault be
detected, the injection will not start. The
functioning method complies with E DIN
VDE 0126-1-1. In case of an insulation fault
at inlet 2 of the PV generator, for example,
«error 021» will be flagged.
Errors 023 to 025
· DC injection
Your Solar Inverter continuously monitors
the quality of the injected electricity. If an
increased share of DC current is detected in
the injected electricity, the Solar Inverter
will stop the injection The Solar Inverter
will only try to continue the injection after
the system has been shut down and restar-
ted manually, or automatically the next
day.
Error 026
· Isolated operation
Your Solar Inverter is equipped with a
high-quality redundant grid monitoring
system that complies with E DIN VDE
0126-1-1 and continuously monitors the
grid. If one of the monitoring phases fails,
or if the phase relation changes between
the individual conductors, the Solar
Inverter will stop the injection and only
restart when the error has been elimina-
ted, i. e. when the AC grid works properly
again.
