I have a 6.8 kW solar pv system with 2 x 5 kW batteries (and I'm going to add another 5 kW battery at the beginning of April). I do get paid for exporting to the grid.
The installer set it up so that I charge the batteries at night from 12 to 4 a.m. I'm happy with that. The issue is that my heating kicks in at 6.30 and the battery starts to discharge. I don't want that as my cheap rate runs until 8 a.m. Ideally, I dont want the batteries to discharge until 8 a.m.
The other wrinkle I have is that I have an EV. Currently I have it set up to charge from 4 a.m. to 8 a.m.
What are the most efficient settings for my inverter so that I maximise the cheap rate (which runs from 11 p.m. to 8 a.m.?
