I had a slight technical hitch, got home from work, checked my phone and the system was pulling house load from the grid, luckily the batteries were fully charged.
Seems I forgot to make the grid setpoint negative I had noticed that error last night, then forgot to fix it.
Consider that a complaint against the low rates. Pulled 1.2kWh, now discharging to grid at 5kWh as the oven etc is on.
I exported 3.7, I ended it 15 mins early as I didn't want to run out later tonight. In hindsight, I probably could have exported for the full session as I am still at 30% battery and the heat pump will drop off in 15 mins.
