Derating
15.1
Ambient temperature
At an ambient temperature of up to
50°C, the inverter
supplies continuous nominal power. When operating the
inverter at an ambient temperature of
>50°C,
a power
derating of 2.5%/K
should be ensured.

15.2
Installation height
The inverter can be operated at an installation altitude of up
to 2000
m without any limitations. Different data applies for
installation locations above 2000
m due to the differing air
pressure and the reduced convection cooling associated
with this.
A power derating of 0.6%/100 m should be observed for
installation heights between 2000 and 3000 m.
