Battery config alternative (EV Charger connected before battery power meter)

[blb4github]

Description
Currently evcc assumes the battery default behaviour is “self use mode” (or net zero) where the battery tries to keep net zero based on grid power (including all loads, so also including the Charger). As in my case (11 kWh/2,5kW) it doesn’t make sense to charge the EV from the battery I did connect the charger before the battery power meter which works perfectly for me. evcc (as the optimizer) is now always assuming the battery will discharge when the EV is charged which isn’t the case. Off-course the history graphs are good because all the meters including the P1 port meter reading are showing reality.

what I would like
It would be great if you can configure the location of loads related to the battery. As a result evcc (optimizer) would know as default behaviour the battery will not react on charging the EV. It would be great if the UI will give the option to discharge the battery on request during charging.

Describe alternatives you've considered
I can off-course change the position of the battery net zero power meter but that would make all depending on evcc (or HA) where everything works now as required based on in-build battery charger functionality.

A drawing would help. Seems your EV is entirely outside the grid meter limit?

Thanks, this is how it is connected:

The Battery system (Solax Hybrid inverter) doesn't measure the power to the EV Charger. The SolaX meter is not used in evcc, the grid meter is used.
