The operating temperature range is shown diagramatically in the figure below:
Relative air humidity for the Inverter is ≤ 95 % non-condensing.
If the Inverter is to be installed at an altitude > 1000 m (> 3280 ft) derating will be required.
The figures below show the derating required according to altitude.
