EnergySage said that a typical centralized residential chain inverter will last 10 to 15 years and will therefore need to be replaced at some point during the life of the panels. Chain inverters usually have standard warranties that range from 5 to 10 years, and many of them have the option of extending to 20 years. Solar inverters have a variable lifespan. This is because most chain inverters have an estimated lifespan of 10 to 15 years, while some DC microinverters and optimizers have an expected lifespan of 20 to 25 years.
Photovoltaic inverters based on cells isolated from the grid, on the other hand, have a much shorter lifespan, ranging from 2 to 10 years, according to the manufacturer. Residential solar systems can last up to 30 years in total. As a result, you'll almost certainly run into a worn-out inverter at some point in the setup and will have to replace it. Solar energy systems are said to have a lifespan of about 25 years.
However, most solar inverters may not last that long. Most of them have a life expectancy of ten years. Microinverters work better than string inverters when a cloud or screen partially covers the board, but they are much more expensive. Off-grid solar inverters vary in model, shape and brand, and solar inverters have a shorter lifespan than solar panels.
Although the estimated lifespan of solar inverters is ten years, in fact there are cases where inverters have lasted twenty years or more. The temperature inside the inverter is the most important factor affecting the lifespan of the solar inverter. While inexpensive and popular, String inverters are incompatible with solar cells, a new type of battery inverter. However, solar inverters last up to 25 years, depending on many factors, such as the type, brand or model of the inverter.
