2.4 Derated application

2.4.1 Derating due to temperature

The standard ambient temperature of inverter unit is in the range of +40℃ ~ +50℃, and the rated output
current of inverter unit must be derated by 1% for every 1℃ increase when the temperature exceeds 50℃.
The current reference value multiplied by the derating coefficient (k
temperature higher than 50℃.

2.4.2 Derating due to altitude

The inverter unit needs to be derated by 1% for every increase of 100m when the altitude exceeds 1000m.
Contact our local technical support for model selection when the altitude exceeds 2000m.
