Power limitation (Power Derating)
In order to allow inverter operation in safe thermal and electrical
conditions, the unit automatically reduces the amount of power fed into
the grid.
Power limiting may occur due to:

The aforementioned power limits may vary depending on the grid standard of the country of
installation.
P ower reduction due to environmental conditions
The power reduction value and the inverter temperature at which it
occurs depend on the ambient temperature and on many operating
parameters. Example: input voltage, grid voltage and power available

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.
