I have a multiplus 2 5KVA, actually 3 of them connected in parallel (its for 3 families living on the same premises). Currently our stoves and geysers are controlled via a 230VAC (the coil drive) relay, that kicks them out when the grid is down. I am hoping for us to go off grid, but to do that I would first need to change what controls this relay. Instead I would like it to disconnect the geysers/stove when the battery is below say 35%.
Can the multiplus 2 be programmed to do that? Or do I need like a separate arduino with voltage measurement? Any recommended documentation for me to read? I understand circuits and programming. I see what looks like IO connects at the bottom of the multiplus connection block section.
Cheers!
