If you really want to use Solar Power for charging your Car you have with the ABB Charger the option to install a Smart Meter, but that comes with a price and the problem that it's almost impossible to find a Company to install this one for me. Fortunately I have not really a clue about electrical Systems, so I will not touch my installation.
I have an ABB Installation Guide for it, but it's a PDF File which I can't attach here.
