Residual
Current
Abnormal
The insulation
resistance against
the ground at the
input side
decreases
during the inverter
operation which
,
causes excessively
high residual
current
.
1 If the alarm occurs accidentally possibly the external
.
,
circuits are abnormal accidentally The inverter
.
automatically recovers to the normal operating status
after the fault is rectified
.
.
,
2 If the alarm occurs repeatedly or lasts a long time
check whether the insulation resistance against the
ground of PC strings is too low
.
PV Strings
Abnormal
PV strings have
been shielded for
a long time
.
PV strings are
deteriorating
.
1 Check whether the PV string is shielded
.
.
.
,
2 If the PV string is clean and not shielded check
whether the PV modules are aging or deteriorated
.
PV Strings
Reverse
The cables of PV
strings are
connected
reversely during the
inverter installation
.
Check whether the cables of PV strings are correctly
connected If they are connected reversely reconnect
.
