Thinking ahead to higher solar production .. for (say) Apr to Oct if my batteries are filled overnight at 7p I will not need to charge them further in the daytime (24kwh batteries are more than enough outside heating season) so would prefer to maximise exports at 15p... not filling batteries from solar.
my ideal scenario would be as follows:
- Always charge batteries (ideally) using both overnight IOG slots and dynamic additional slots.
- Using batteries to supply home demand in the day whenever there is insufficient solar.
- Solar will be used for home demand when available
- Exporting ALL solar not needed for home demand. I.e. NOT filling batteries
I guess I'm looking for:
- "hold" on charging batteries from solar during the day
- ideally the "hold" would be overriden by dynamic cheap charging slots. Maybe impossible?
- but discharge continues to work normally
Can WW recognise charging from grid dynamic slots ... without also charging from solar? If necessary I'd be happy to lose summer dynamic slots as I doubt they'll be very important to me.
I suppose it might be viewed as splitting "hold" into 2 elements
- Hold charge
- Hold discharge
Hold charge would be the main piece I need so that the batteries do not charge (from solar) for a period that I can set. My main solar production is say 09:00 to 15:00 so outside those times I would benefit from IOG dynamic & overnight slots.
Have I explained what I mean?!
Last year I produced circa 6500kwh solar
I exported approx 2000kwh
I used approx 3300kwh directly
I filled batteries with approx 1200kwh
I'm thinking I may be able to significantly increase my exports at 15p and replace with imports at 7p. On above figures perhaps only 1200kwh would save £96. But in reality I suspect actual exports might be increased even further.
Any thoughts?
