Error
Errors 031 to 033
Grid overvoltage
> 10 %
Errors 034 to 036
Control error
Causes
The grid voltage of the
injecting phase is too high.
The Solar Inverter monitors
the lower and upper admis-
sible grid voltage limits.
If the voltage exceeds the
upper limit by 10 % (U
max
=
253 V), the Solar Inverter
will automatically be discon-
nected from the grid after
10 minutes (in compliance
with E DIN VDE 0126-1-1).
The cable cross-section of
the AC supply line to the
Solar Inverter is insufficient.
Your PV system injects elec-
tricity into an insufficiently
rated spur line.
The self-monitoring Solar
Inverter has detected a con-
trol fault.
Remedies
The grid impedance of your grid connec-
ting point is too high.
Ask your power supply company about
the stability and design of the grid.
Check the rating of your grid connection
(power meter) or the grid injection point
to your power supply company.
Ask your power supply company about
the stability and design of the grid.
Please call the technical hotline. The
phone number is on the back of the
user manual.
