About What is the normal temperature of photovoltaic inverter

It’s well understood that heat affects PV modules – they are tested and rated at 25 degrees Celsius and every degree above that causes power output to drop by up to .5% per degree, depending on the type of semiconductor used. The temperature of the module is directly affecting voltage.

What is not as well understood is that heat also affects solar inverters. The reasons are not the same – although the solar inverter has semiconductor parts in it which loose.

As the inverter works to convert DC power to AC power, it generates heat. This heat is added to the ambient temperature of the inverter enclosure, and the inverter dissipates the heat through fans and / or heat sinks. The heat needs to stay below a certain level at which.The optimal operating temperature for a solar inverter is typically within the range of 20°C to 25°C (68°F to 77°F).
