I have a requirement for the system to not charge the battery from grid for a set period of time, say 30 minutes, after grid has returned following a power outage/loss of mains.
Ignoring AC in for same set period after grid return would also be a solution but secondary to having only battery charging delayed as loads on inverter output would also be affected. Would be ideal if this can be achieved using some combination of Assistants and programmable relays.
