Been running my system for a few weeks. Has lead acid batteries that are quite small. So I decided to introduce a scheduled charge in the afternoons to ensure the batteries are charged by the time the sun sets.
I noticed that as the battery reaches a full state, the solar charge taken is quite low - i.e. its 2pm, AC draw is 2100W, while I typically get about 3000W from the panels at this stage (no clouds), but only getting half that and the rest is drawn from grid (setpoint set at 50W!)
I also tested, if I turn off scheduled charge, solar PV charger kicks up to AC load level and grid drops to setpoint of 50W.
What am I missing?
