Active Cooling for Solar Inverters

We offer active cooling kits for solar inverters, including model-specific solutions for GoodWe and SolaX, as well as universal cooling systems suitable for a range of installations.

Our cooling kits feature high-quality Sunon fans, safe 24V DC power and options with or without a thermostat. Active airflow helps dissipate heat generated during inverter operation. The cooling systems are designed for external installation without modifying the inverter's internal electronics.

Choose Cooling for Your Solar Inverter

Select a cooling solution according to your inverter model and installation requirements.

Why Use Active Cooling for a Solar Inverter?

Solar inverters generate heat while converting electrical energy. During periods of high solar production and elevated ambient temperatures, effective heat dissipation becomes especially important.

Active solar inverter cooling improves airflow around the inverter's cooling surfaces and helps reduce operating temperatures.

Lower operating temperatures may help reduce thermal stress on electronic components and limit temperature-related power derating. The actual cooling effect depends on the inverter model, operating load, ambient temperature and installation conditions.

Cooling With or Without a Thermostat?

Cooling with a thermostat automatically switches the fans according to the temperature measured by a sensor. For our thermostat-equipped cooling kits, the standard switching temperatures are 40°C ON and 35°C OFF.

Cooling without a thermostat is suitable for customers who prefer their own external fan control, such as a compatible smart plug, automation system or timer.

Both options provide active airflow. The best choice depends on whether you prefer automatic temperature-based operation or integration with an existing control system.
