Grid Under-voltage Derating
Once the grid voltage is in the defined range of Vgrid (Vmin…215V), the inverter
will decrease the power output.

Grid Under-voltage Derating
Over-temperature Derating
Power modules over-temperature may result from high ambient temperature, poor
ventilation or fault of fans. Over-temperature derating may protect the inverter as
well as the power modules against damage.
