
Altitude derating
The inverter load capacity (current and power) decreases if the installation site altitude
exceeds 1000 metres (3300 ft). The derating is 1% for every 100 m (328 ft). For the
maximum installation site altitude, see section
Ambient conditions on page 144 .

Temperature rating curves
The load capacity (current and power) decreases if the ambient temperature exceeds the
nominal ambient temperature.
