Active Cooling: 3 x Sunon 60mm fans, Vapo (MagLev), rated lifespan of 70,000 hours, noise level 31dBa, total airflow of 138m³/h
Power Consumption: Stand-by 0.5W, operating 7W
Material: Construction made using 3D printing

Function Description:
Active cooling brings air from the bottom direction. By using the cooling system, you can reduce the inverter temperature under load by 15-30 degrees (depending on installation conditions). This will prevent production limitations on hot days and simultaneously extend the lifespan of the photovoltaic inverter. The thermostat is set by default to turn on the cooling at 40°C and turn it off at 35°C, measured at the inverter fin where the sensor is installed.

Installation:
The installation is done by sliding the cooler under the inverter and then snapping it onto the bottom ends of the fins. The sensor is threaded behind the inverter and placed on the fins in the left third, towards the middle. Insert the sensor at the rear and slide it forward until it fits securely. Do not place the sensor in the center of the inverter, as the temperature would be affected by the airflow. To remove, turn the side locking screws to the stop and slide the cooler off. Do not tighten the locking screws before installation.

Setting the Turn-On and Turn-Off Temperature:
