Over-temperature Derating(Pf=1)
Lower limit of the over-temperature derating: about 50% of the
nominal power.
When both the module temperature and the internal temperature
meet the derating condition, inverter limits its power according to
the lower power limit value of the two.
Grid Under-voltage Derating
When the grid voltage is low, the inverter will derate the output power to make
sure the output current is within the permissible range. Once the grid voltage is
within Vmin…600V, the inverter will derate the output power.
