How Does Active Inverter Cooling Work?

The cooling unit directs air towards the inverter from below, improving heat dissipation through its cooling fins.

Under load, the cooling system can reduce the inverter's operating temperature by approximately 15–30°C, depending on installation conditions. Lower temperatures may help limit thermal power derating during hot weather and reduce thermal stress on electronic components.

Automatic Thermostat Settings

The thermostat is preset to the following temperatures:

• Cooling switches on: 40°C
• Cooling switches off: 35°C

Temperature is measured by a sensor attached to the inverter's cooling fins. The fans operate automatically according to the measured temperature.

Easy Installation Without Inverter Modifications

Watch the Cooling Kit Installation Video →

Slide the cooling unit underneath the inverter and fit it onto the lower ends of the cooling fins. The locking screws on the sides of the frame can be used to secure its position.

Route the thermostat temperature sensor behind the inverter. Position it on the cooling fins approximately one-third of the way across from the left side and around the middle of their height.

Insert the sensor from behind the inverter and slide it forwards until it is held securely in place.

To remove the cooling unit, follow the installation steps in reverse order.

Adjusting the Thermostat Temperature Settings

Instructions for changing the thermostat's switching temperatures are included in the user manual supplied with the cooling kit.
