• Check the grid frequency and observe how often
major fluctuations occur.
If this fault is caused by frequent fluctuations, try
to modify the operating parameters after informing
the grid operator first.
E34
• Check the grid voltage and grid connection on
inverter.
• Check the grid voltage at the point of connection
of inverter.
If the grid voltage is outside the permissible range
due to local grid conditions, try to modify the
values of the monitored operational limits after
informing the electric utility company first.
If the grid voltage lies within the permitted range
and this fault still occurs, please call service.
E35
• Check the fuse and the triggering of the circuit
breaker in the distribution box.
• Check the grid voltage, grid usability.
• Check the AC cable, grid connection on the
inverter.
If this fault is still being shown, contact the
service.
