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.

I've had no difficulty with E-On, although they were a rubbish supplier.
