Hello, I see the similar problem with my Infini 3kW+. I do not possess any advanced sofware yet, just stick with solarpower and observation. I use grid tie with backup (II) mode, charge battery from PV only, no grid backfeed (PV first load, then charge bat.) I found that when I turn the grid swith OFF during battery charging (max 25A) the level of PV input rises about 200W +-, so that shoud be its own power consumption during max charging which it should get from PV, but uses grid instead. Also during night when on battery, if grid is ON, the overall power drained from battery is considerably less then when I switch the input grid OFF (I guess about 1-1,5kWh). I would appreciate if there is some setting to reduce the self-consuption or kill it entirely so the inverter will drain power only from battery or PV and use grid power only if the battery is very low. If I use the grid swith OFF, it functions all well (in the time with sufficient PV input + - from spring to autumn), but there is no immediate backup if the battery drains too much. Thaks for any advices.
