I’m not sure how typical a user I am, but I usually want to charge my battery using the cheapest slots overnight, and then occasionally set 1 or 2 slots manually in the afternoon when there’s been no solar or I’m concerned the battery won’t get us past 19:00 / to the next cheap overnight slot. So overnight, I would generally like to hold the charge (so EV can complete charge etc) and then, when the prices start going up / household demand increases, I want to run off the battery.
Maybe setting one or more ‘Hold windows’, same as the Charge windows, to pre-allocate periods each day, is the best fit for most people’s needs? I’m not sure how easy this would be to implement, as I guess at the end of each charge period, you would need to check if the user was in a hold period & then alter the Charge Stopped Soc if necessary. (I assume the Charge Stopped Soc is automatically reset to 100, in the Growatt implementation, at the start of each charge period?)
Sorry, I’ve just re-read your post above, and realised this is, in effect what you’re suggesting at the end!
