Malfunction Description Remedies
208:UAC3<Min Your solar inverter is equipped
with a three-phase voltage
monitoring function according
to DIN VDE 0126-1-1. It con-
stantly monitors the voltage
level of the individual phases
(here: L3). When the minimum
permissible limit is dropped
below, the solar inverter stops
feeding and does not start up
again until the voltage value
exceeds the minimum permis-
sible limit.

Ask your Electric Utility
about grid stability and de-
sign.
209:Isol.op. You solar inverter is equipped
with a high-quality redundant
grid monitoring function ac-
cording to DIN VDE 0126-1-1
and constantly monitors the
grid. If one of the phases fails,
or if the phase position be-
tween the individual conduc-
tors changes, the solar inverter
stops feeding and does not
start up again until the error is
eliminated.
➡
Check the phases L2 and L3.

Ask your Electric Utility
about grid stability and de-
sign.

210:Frq1>Max The solar inverter continually
monitors the grid frequency of
the phase feeding in. If this lies
above the permissible value,
the solar inverter stops feeding
and does not start up again un-
til the value is below the limit.

211:Frq1<Min The solar inverter continually
monitors the grid frequency of
the phase feeding in. If this lies
below the permissible value,
the solar inverter stops feeding
and does not start up again un-
til the value is above the limit.
