Load balancing does not work ok.
I have 3x20A fuses, Max power from the grid set to 20A and I'm on the latest FW v1.4.2.
If my house consumption is low and I start charging it charges full power 11kW. I can also see on the meter 16-18A (charging+house load) on each phase, everything ok.
Now if I start the oven, the charging stops and I can see on the meter L1 1A, L2 0.5A, L3 11.3A which is house load with the oven on. Offered current decrease to 9A (i see over OCPP) and if I monitor my tesla app I see max offered power 8A, still everything ok.
The charger now starts increasing current from 0 to 8A, but when it comes to 4 or 5A charging stops and starts from zero again to 4-5A. This repeats over and over again. I left it for 15 min and it was still doing the same thing, inc. to 4A and stops. If I stop the oven, offered power returns to about 18A, and then normal charging continues.
Something isn't right here.
