U> (10Min) Der.
Enables power derating mode due to high average grid voltage readings
Slow Ramp
Enables gradual ramping up of power after the grid connection.
OF Derating
Selects the power derating mode in the event of grid over-frequency.
0 Derating disabled
1 BDEW derating
2 VDE-AR-N derating
3 CEI derating
OF Der. Rest. T
Time period after OF derating in which the inverter checks that the fre-
quency is back within the operating ranges (parameters Fconn< and
Fconn>) required by the grid standard before ramping up the output from
the derating condition
1 ... 1000S
Amorph. Enable
Enables Amorphous Mode in the event that the negative input pole is
grounded by installing the Negative Grounding Kit (not available)
Enabled/Disabled
Reset Country S.
Unlocks the grid standard selection (resets the 24 hours available for chan-
ging the grid standard)
