Re: System down!
My SMA Sunny Boy 2500 was installed in March 2010, so now in its 16th year and going strong. Probably helps that my panels are 2.1kW, which means that the inverter is oversized. 15 years ago installers were reluctant to undersize inverters.Fintray wrote: ↑Sat Apr 26, 2025 3:34 pmIn the UK grid tied inverters would be the most common, my SMA Sunny Boy is now 15 years old and hoping it goes on for a while yet.MikeNovack wrote: ↑Sat Apr 26, 2025 2:30 pm Meanwhile ---- Are grid tied inverters common/uncommon in the UK? Mine lasting 8+ years not terribly bad, considered normal MTBF 10-15 years.
