2.3.3 Derating
Derating the output power is a way to protect the inverter from overload and
potential malfunctions. Inverter’s derating function can be activated in the following
scenarios:
y
PV input overload
y
Too low grid voltage
y
Too high inner temperature
y
Power limit setting on the inverter LCD display
y
Grid frequency too high (when the Country selection is “DE” or “IT”)
PV Overload Derating
When the PV input power exceeds the defined
TotalInputPowerMax, see Tab. 2-2
, the
inverter will reduce the power evenly to the maximum limit and keep the output
power at nominal value.
