Here is an example of what is happening with our VPP battery:-
- Lights out at 11.30pm.
- Battery state of charge as at midnight: 56%
- Battery state of charge at 7 am (No solar in yet): 35%
- Grid draw during that 7 hours: 1.8 Kw
Why should any power at all be drawn under these circumstances? Max power use during these hours peaked at 320 watts and was mostly around 100.
I was told by email that Sunverge are treating this issue with priority and that software updates would fix it during April and the end of May. So far, I have not noticed any change at all. I monitor it every night & morning.
What have others noticed with their overnight grid draw?
