Temperature control
The thermal model of the inverter controls the cooling of the inverter as well as protects it.
The thermal model controls the operation and speed of the cooling fans and limits the
output current, if needed. Overtemperature warning is indicated if the inverter temperature
exceeded the limit and current limitation is activated. If the temperature of the inverter
continues to increase, a fault is triggered and the inverter disconnects. The fault has to be
reset manually.
