Study confirms rule of thumb that PV inverters should run without faults for around 15 years

A new study by Bern University of Applied Sciences shows that the performance of most PV inverters and power optimizers remains optimal for up to 15 years. The inverters considered came mainly from the manufacturers Fronius, Sputnik, and SMA and most of the power optimizers examined came from Solaredge.From pv magazine Germany Researchers at Bern University of Applied Sciences (BFH) are currently investigating the durability and performance of PV inverters and power optimizers from a total of 1,280 PV systems located in Switzerland. In their survey, the researchers considered the type of power ...
