When I take a look on my historcal data there is a huge difference between consumption and production. I have a 15.4kWh BYD battery installed. Sum of production would be 44+2.2kWh=46,2kWh. Sum of consumption would be 13kWh+16kWh+about 12.5 to Battery=41,5kWh. So difference is about 5kWh. Is the whole difference caused by efficiency of the system and some rounding error of the data? Is this OK?
