Well I am measuring at the tails from the panels, using a meter designed to measure the house consumption at the incomers, so it may be inaccurate. I'm not sure how I could get a better reading; my Smart-meter In-house Display only shows metered energy consumption figures and not outgoing figures and I don't know of a convenient way to do it. The Inverter is a Platinum 3800 or 4200 (I think) made by Diehl. There is no mention of a standby or sleep mode. Since it was installed in 2011, I assume that the design pre-dates that by some years and perhaps they didn't have that feature back then. > And yeah solar has paid back the investment over the years even if SSE > has defaulted on the FITS payments this year.

I've had no difficulty with E-On, although they were a rubbish supplier. -- Terry Coles -- Next meeting: Online, Jitsi, Tuesday, 2022-08-02 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:firstname.lastname@example.org
