Messages on the display and the "Fault" LED

Many fault signals indicate a fault in the grid. They are not operational faults of the inverter. The minimum triggering
levels are determined by standards (e.g. VDE 0126-1-1). The inverter must switch off if the permitted values are
undershot or exceeded.

Explanation
Self test: Grid parameters and genera-
tor voltage are being checked.
Generator voltage and power are too
low; situation before transition into
night shutdown
Checks the shutdown of the power
electronics as well as the line relay
before feed-in mode. The self-test
consists of three successive individual
tests with the status 7, 75 and 8.
In case of overheating, the inverter
switches off . Possible causes:
• Ambient temperature too high
• Fans covered
• Inverter defect
• Fault signal relay has switched.
• Feed-in was ended due to a fault.
• The fault signal relay deenergizes again.
• The inverter feeds back into the grid again
after a country-specifi c time period.
