Active Cooling for GoodWe Solar Inverters
Looking for effective GoodWe inverter cooling? Explore our active cooling kits designed for GoodWe ET Plus+ (5–10 kW) and GoodWe ET G2 / ET-20 (6–15 kW) solar inverters. Each cooling system features Sunon fans, a 24V DC power supply and a mounting design tailored to the corresponding inverter series.
Choose a cooling kit with a thermostat for automatic temperature-based fan control, or a version without a thermostat for external switching. Active airflow helps remove heat from the inverter and reduce operating temperatures.
Active Cooling for GoodWe ET and ET G2 Solar Inverters
GoodWe solar inverters generate heat when converting electrical energy. During periods of high solar production and elevated ambient temperatures, effective heat dissipation can be important for stable operation. Active GoodWe inverter cooling improves airflow around the cooling fins and helps reduce inverter operating temperatures.
Depending on the installation conditions and inverter load, the temperature reduction can be approximately 15–30°C. Actual results depend on the inverter model, ambient temperature, airflow and mounting conditions. Lower operating temperatures may help reduce thermal stress on electronic components and limit temperature-related power reduction.
Which GoodWe Cooling Kit Do I Need?
Choosing the correct cooling kit starts with identifying your exact inverter model. Different GoodWe inverter generations have different designs, so we recommend selecting a cooling system specifically intended for your inverter series.
- GoodWe ET Plus+ (5–10 kW): Cooling kits for the ET Plus+ series, including selected 16A models. Available with an automatic thermostat or without a thermostat .
- GoodWe ET G2 / ET-20 (6–15 kW): A separate GoodWe ET G2 cooling kit with thermostat , designed for the newer inverter generation.
Before ordering, check the exact model designation on your inverter and make sure there is sufficient space for installation. If you are unsure about compatibility, please contact us.
GoodWe Cooling With or Without a Thermostat?
Cooling with a thermostat automatically switches the fans according to the temperature measured by a sensor positioned on the inverter's cooling fins. The standard settings are 40°C for switching on and 35°C for switching off. This provides automatic operation without everyday manual switching.
Cooling without a thermostat has no built-in temperature control. It is suitable for customers who prefer to control the fans externally, for example using a compatible smart plug, automation system or timer. Appropriate external switching must be provided.
Sunon Fans and 24V DC Power Supply
Our GoodWe cooling systems use three Sunon fans with Vapo (MagLev) technology. Fan dimensions, airflow and power consumption vary depending on the selected cooling kit.
The cooling systems operate on 24V DC and include a compatible power supply. Their mounting designs allow installation without modifying the inverter's internal electronics.
Installation procedures and required clearances vary between inverter models. Please follow the instructions supplied with your cooling kit and the inverter manufacturer's guidelines.

Frequently Asked Questions About GoodWe Cooling
Can I use the same cooling kit for GoodWe ET Plus+ and GoodWe ET G2?
No. The ET Plus+ and ET G2 inverter generations have different designs. We offer separate cooling kits adapted to each series.
Do I need a thermostat?
Not necessarily. You can choose a version without a thermostat if you provide suitable external fan control. A thermostat version is more convenient if you prefer automatic temperature-based operation.
How much can active cooling reduce inverter temperature?
Depending on installation and operating conditions, the reduction can be approximately 15–30°C. This is an indicative range, not a guaranteed result for every inverter.
Do I need to modify my GoodWe inverter to install the cooling kit?
The cooling kits are designed as external accessories that do not require modifications to the inverter's internal electronics. Always follow the cooling kit installation instructions and the inverter manufacturer's requirements.
