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 photovoltaic inverter and then snapping it onto the bottom ends of the fins. Next, secure it to the fin with the side screws. 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. To remove, follow the reverse procedure.

Setting the Turn-On and Turn-Off Temperature:
