10.6 Power reduction
In order to ensure inverter operation under safe conditions, the device may
automatically decrease power output.
Power reduction depends on many operating parameters including ambient
temperature and input voltage, grid voltage, grid frequency and power available from
the PV modules. This device can decrease power output during certain periods of the
day according to these parameters.
Notes: Values are based on rated grid voltage and cos (phi) = 1.
