Fault display
Fault 6
Grid under-
voltage,
1-phase
Fault 7
Grid overvoltage,
1-phase
Causes
The grid voltage of the fed-
in phase is too low.
The grid voltage of the fed-
in phase is too high.
Remedies
The solar inverter monitors the limits of
the minimum and maximum permissible
3-phase grid voltage. If the values fall
below these limits (U
min
= 184 V), the
solar inverter switches off and only
restarts automatically when the voltage
value has returned within the limits.
The fault cut-out can be triggered even
if the values only exceed or fall below
the limits very briefly.
Ask your electricity board about grid
stability and design.
Check the format of your grid connection
(energy counter) and the grid feed-in
point to your electricity board.
The solar inverter monitors the limits of
the minimum and maximum permissible
3-phase grid voltage. If the values exceed
below these limits (U
max
= 264 V), the
solar inverter switches off and only
restarts automatically when the voltage
value has returned within the limits.
The fault cut-out can be triggered even
if the values only exceed or fall below
