Question: I’m running an ESS setup with ACcoupled PV with feed-in allowed. First I was using only a mppt but for some reasons I temporarily disconnected it and only using ACcoupled PV on ac-out.
Battery setting is optimized with batterylife(because of passive balanced lithium). Al worked well, but now there is only ACcoupled PV available the systems thinks there is no incoming power and it raises the active state of charge limit so it won’t discharge anymore while there is sufficient charge current available each day.
For now I set it to optimized without batterylife but that’s not the way to go. What is going wrong here?
ACcoupled PV 440Wp on AC-out
RPI with Venus
8kWh LiFePo4, passive balanced
MPPT150/35(not used, but connected)
