Solar inverter useful life is 10 15 years for both types string or central inverter although some micro inverters last 20 years. On a Solar PV Electric System, the inverters will usually be the first thing to go. The temperature within the inverter is one of the most important factors that directly affect the performance and life of solar inverter devices. Higher internal temperatures will reduce the performance and life of your solar inverter. Extreme temperatures, humidity, and dust can reduce the Solar inverter lifespan.
