Error
Error 027
Grid overvoltage
3-phase
Errors 028 to 030
Surge fault
Causes
The grid voltage is too high.
The Solar Inverter monitors
the lower and upper admis-
sible grid voltage limits in
3-phases. If the voltage
exceeds the upper limit
(U
max
= 264 V), the Solar
Inverter will automatically
switch off and will only
restart when the voltage
value drops below the
upper limit again. The shut-
down can already be trig-
gered if the voltage rises
above the upper limit for
a short time.
The Solar Inverter has detec-
ted a high voltage peak in
the injecting phase.
Remedies
Ask your power supply company about
the stability and design of the grid.
The Solar Inverter will automatically
restart when the error has been elimina-
ted. Should the error occur often, please
consult your power supply company.
