[QUOTE="the-chauffeur, post: 551419, member: 37642"] Thanks folks. It's clear the MPPT thing - and the specific/related capability of the inverter - is something I'd have to do a bunch more research on before I would be in any way confident that I wouldn't melt/blow/damage something. Making the switch during the hours of darkness would be simple/safe enough, but the midday switch is a whole different ballgame - and as you've warned, could end very badly depending on the inverter capability. In order to get the right panels working at the right times, I think I'd need at least four switches so various circuits could be energised or disengaged. As a bare minimum, I'd need to split out/rearrange the existing string splits so they comprised half the panels on one side of the roof and half on the other. (as opposed to their current set-up of being split by roof halves). From there, it would be a case of creating sub-groups to energise/disengage when necessary. I'm guessing Home Assistant could be used to control something that in turn would trigger relays to handle the switching. I've already put a load of time into sorting out the active cooling for the inverter and heating for the batteries and will almost certainly end up running all of that via HA. Either way, that's another rabbit hole I'm currently staring down and I can already feel that I've got some coding learning in my future. Ultimately the maths plus the research plus the cost of rewiring will more than likely mean that for now at least this remains little more than a thought experiment . . . an interesting one but a thought experiment nonetheless.
