How reliable is a photovoltaic inverter?
High reliability and long life of photovoltaic (PV) inverters are critical for the successful operation of PV power plants. As inverter products mature and new inverter models are introduced to the market, consumers, project developers, and project financiers are looking for methods to better predict reliability and product useful life.
How long do PV inverters last?
But the PV inverter lifespan ranges from 10 to 25 years, depending on the type. Most average inverter lifespan, and the lifespan of energy storage inverters and hybrid inverters is 10 years. However, microinverters, such as 500w inverter, last even longer. Even within one type of PV inverter, the lifespan of individual models may vary.

How long do solar panels last?
While solar panels can last 25 to 30 years or more, inverters generally have a shorter life, due to more rapidly aging components. A common source of failure in inverters is wear and weathering on the capacitors in the inverter. The electrolyte capacitors have a shorter lifetime and age faster than dry components, said Solar Harmonics.
What factors affect the inverter lifespan?
It is generally believed that the main culprits that affect electronic components are high temperature, dust, oxidation, moisture, etc. Therefore, the inverter lifespan is also affected by these factors, which requires operators to perform necessary maintenance to extend their inverter lifespan.
