Inverter H1-5.0-E
Battery ECS2900-H2
Hi, I presume this is the normal operation of Foxx-ESS battery storage? When I set minimum SOC to say 30%, the batteries stop discharging power once the SOC is reached, but then slowly, over several hours, the battery reduces to 25% & then charges at approx 0.5kWh until 30%. The cycle then repeats until PV charges the batteries above 30%. Could anyone please confirm if this is normal?

the bms needs power to know when to charge/ discharge it will take this from the battereies rather than grid, it is trying to be clever and not take from grid. if the array does not kick in in time it will top back up from grid until array kicks in
