After a first day of using ESS I managed to charge my 42kw battery to 33%, but this evening I was using over 4000w during cooking and noticed it was drawing over 500w from the grid, surely this shouldn't happen. My multiplus ii is 10kva and I did not apply an inverter limit during ess setup, But im wondering if it has anything to do with me setting my ac coupled pv to 4000w? In ve config?
Is there anything I can do to stop such high grid draws?
Does peak shaving have anything to do with it as its set to above maximum soc only, and this is an area I don't understand, can anyone explain what peak shaving means?
Also when I started the setup configurations I first updated the firmware for the cerbo and multiplus
