The lifetime of electronic devices will be reduced by half with the increase of temperature of environment by 10 C. The internal temperature of photovoltaic inverter will increase dramatically in the hot sun for a long time, which will seriously affect the life of the key components of the inverters. The inverters will operate at a reduced rate in order to protect the internal components, and even the temperature fault of the inverters will be caused by excessive temperature. It is suggested that solar shade should be added to photovoltaic inverters to avoid the sun exposure.

If installed outdoors, photovoltaic inverters should be equipped with rain-proof sunscreen to avoid direct sunlight and rain immersion. Inverters should not be directly exposed to the sun or other heat sources. There should be enough space for its installation and mobile inverters. At least 50 cm space distance should be left around the inverters of the upper and lower air outlets. The inverters with the left and right air outlets are supplied from the side, and the space distance between the two sides should be more than 100 cm
