Active Cooling GoodWe ET, ET-plus 24V DC - w/o Thermostat

Cooling Variant without Thermostat (Regulation)
The turning on/off of the cooling fan for solar inverter must be controlled externally, for example, via a switched socket in combination with automation that monitors the inverter temperature. Another option is a socket with a timer – turned on during the day and off at night.

Function Description:
Active cooling draws in air from the bottom side, contributing to effective device temperature regulation. By using this system, the solar inverter’s operating temperature under load can be reduced by 15 to 30°C, depending on the specific installation conditions. This prevents power output limitations during hot days and also extends the overall lifespan of the inverter.

Installation:
The cooler is installed by first sliding it beneath the solar inverter, then clicking it into place on the lower edges of the cooling fins. Afterwards, it is fastened to the fins using the screws on the sides. To detach the unit, simply reverse the installation steps.
