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.
