I don't understand a few things.
This is a test setup and only a switch is connected as a load.
1. I see that I supply back to the grid, but why does it say 0.0 kWh to grid?
2. I have a BYD premium lvs 12.0, which is charged to 100% daily.
Every morning the battery is at 96% with a constant load of 5W + the self-consumption of the Victron Multiplus.
Every day 2.0 kWh is charged to get the battery back to 100%.
How is it possible that the battery loses 2 kWh per day with a constant 5 watt load ?
