Meanwhile ---- Are grid tied inverters common/uncommon in the UK? Mine lasting 8+ years not terribly bad, considered normal MTBF 10-15 years. The are particularly suited to the "net billing" situation where the grid acts as a giant, essentially unlimited capacity battery. But like I said,the accounting is in money, not KWh.

In 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.

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.
