181 Insulation error, centre The insulation error is located close to the
centre of a PV string. The area -15% of
the half of the modules based on the total
number of modules. When the insulation res-
istance is distributed equally across the entire
string, this message is also generated when
the calculated insulation resistance falls below
the set value. Insulation error close to the
centre of the PV string (area co-15% of
the half of the string) Insulation errors
must be rectified in
order to operate
the system safely
and reliably. B
182 Insulation error, minus The insulation error is located between the
centre of a string and the minus terminal on
the inverter. If the insulation error is located
very close to the minus inverter terminal, then
the error occurs even if the insulation error
<150 kOhm and is above the set value. Insula-
tion error on the minus terminal side of the PV
string. See action in the
event of an error
181 B
183 Insulation error, plus The insulation error is located between the
centre of a string and the plus terminal on the
device. If the insulation error is located very
close to the plus inverter terminal, then the er-
ror occurs even if the insulation error <150
kOhm and is above the set value. Insulation er-
ror on the plus terminal side of the PV string. See action in the
event of an error

volt. L1 Protection shutdown grid voltage (effective
value) L1 Incorrect grid
voltage measure-
ment that is outside
the permissible
range. Check the
AC-side wiring (e.g.
increased voltage
due to inductance
capacity of a trans-
former) If the error
display occurs fre-
quently, or every
time, the installa-
tion must be
checked. If the in-
stallation is fault-
free, there is a
device fault. Check
all connection ter-
minals from the
device to the grid
connection. A fluc-
tuating or missing
AC voltage can in-
dicate this connec-
tion problem. B
