PV Power needs to be negative for proper energy accounting #29

Closed fred777 closed 6 months ago

fred777 commented 6 months ago

This should be noted in the readme: PV power must have a negative sign for proper accounting.

With positive power the computed consumption / AC-Load will be wrong, also in VRM portal:

And with negative power - as it is done with any other power source like battery discharge - the computed consumption is correct:

PV power cannot be negative. You probably have a configuration error.

Try to change the PV position.

Yes, you're right! I have two inverters, one of them on ACout. But meanwhile found a better way to integrate them: https://github.com/henne49/dbus-opendtu
