Over-temperature Derating
High ambient temperature, fan broken or poor ventilation will lead to inverter
power derating.
When the module temperature exceeds the upper limit, inverter will derate
power output until the temperature drops within the permissible range.
When the internal temperature exceeds the upper limit, inverter will derate
power output until the temperature drops within the permissible range.
Lower limit of the over-temperature derating: 75% of the nominal
power.
If the module temperature and internal temperature reach to power
derating conditions, inverter will derate the power output according to
the lower temperature between the two.
Grid Under-voltage Derating
When grid voltage is low, inverter will derate the output power to make sure the
output current is within the permissible range. Once the grid voltage is within
Vmin…215V, inverter will derate the output power.
