Power derating due to environmental conditions
The power reduction value and the inverter temperature at which it oc-
curs depend on the ambient temperature and on many operating para-
meters. Example: input voltage, grid voltage and power available from
the photovoltaic eld.
The inverter can therefore reduce the power during certain periods of the
day according to the value of these parameters.
In any case, the inverter guarantees the maximum output power even at
high temperatures, provided the sun is not shining directly on it.
