Hi there. Apologies if this has been asked before. In the US (and perhaps other parts of the world) it is possible to limit the amount that a charging car will drain Powerwalls by adjusting the 'EV charging' options within the Powerwall settings menu. I don't have that option, and am interested whether anyone in the UK has it? It is discussed in these threads in the energy forum:
How to prevent charging cars from battery
how to disable vehicle charging during grid outage?
I have our Zappi car charger on the 'Backed up' side of the Gateway so it could charge from solar during a power cut, but would love the option to limit the battery drain if (for instance) there were a power cut over night while the car is charging. The system appears to work by tweaking the supply frequency so is apparently independant of which charger you have.
Thanks
