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.
When considering the life expectancy of string solar inverters, the average lifetime is less than 15 years, 10 years less than the average lifecycle of solar panels. However, it is possible, with appropriate maintenance checkups, for inverters to last up to 20 years
To prolong the life of a solar inverter, the first crucial step is its installation. Inverters need to be protected from the weather as much as possible. Its electrical components are heat sensitive. The failure rate will depend on its capacitance, operating voltage and temperature.
Furthermore, inverters help regulate voltage levels and prevent the overloading or underperforming of the electrical system. One of the most significant benefits of using a high-quality solar inverter is its durability. While many inverters come with an expected lifespan of 10-15 years, some manufacturers offer up to 25 years of warranties.
The quality of the power grid also significantly affects the lifespan of PV inverters. Voltage fluctuations, harmonic interference, and other issues impose additional stress on inverters, increasing failure rates.
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.
