Watch your inverter temperature to protect lifespan:

Watch your inverter temperature to protect lifespan:

Another solar instructor and I have a question about grid-tied inverter lifespan. I have read that an average lifespan is 11 to 14 years, and the warranties seem to reinforce this. My colleague believes that 20 to 25 years is more likely for modern inverters. I would tend to believe the latter due to more solid-state electronics in today’s ungrounded inverters, but I can find no data to support this. Jeff Foster • St. Louis, Missouri While the expected lifetime of a grid-tied inverter will vary depending on its design, component quality, and the environment it is operating in, lifetimes beyond 14 years are likely for most of the high-quality inverters now available. For power electronics devices, the environment in which they are installed has a significant impact on their life. I’ve seen inverters fail in less than a year when poorly installed and exposed to insects and m...
