Output Power Versus Ambient Temperature

A–4
Once the heat sink on the inverter reaches a temperature limit, the GT Inverter
reduces its energy output to ensure maximum component ratings are not
exceeded. The following shows the maximum continuous output power derating
to be expected at higher ambient temperatures.
