Hello. I have 3-Phase instalation with Multi RS inverters. I have disabled grid feed-in and turned on ESS on Optimised w/o battery life. This is same on all three inverters. It was working great for about 3 weeks but now i have noticed that it started charging from grid with 10A per inverter. So together it is 30A which is significant. Is there some way to stop it ? Only way i can stop charging is conditional disconnect (now would be cycling a lot because very little PV production basically discharge/recharge all the time when grid is on or off) or switch ess to External control. But that discharges battery up to the point it turns off the inverters even with grid connected. Minimum SOC is way lower than current SOC measured with smart shunt. And it has no BMS connected.
Edit : it is possible to lower current by adjusting dvcc current limit. It appears to be 10% of max current.
Edit 2: seems like battery life mode even when disabled. Manually toggling equalisation seems to help but oly for a day or two. Then it starts slowly recharging again.
