[RE-wrenches] Tesla Powerwall 2.0 - AC Coupling

[Dave Angelini Offgrid Solar]

Schneider uses 1.25 max on an XW for Ac coupling. That would be 1.25 x 6
kw or 7.5kw max from the grid inverter when ac coupling. 

I doubt your
numbers would work well with a 5kw internal powerwall. Maybe if you had 2
poweralls? Better get info from Tesla or the installer on Wrenches. Good
Luck!

Considering the lack of public info
available for the Powerwall, does anyone have any insight into the AC
coupling limits for a single Powerwall? 

For example, can we AC couple
10kw Solar Edge to a single Powerwall? 

Thanks

That's going to be long

Jay,


The Tesla Gateway has a 12v input terminal for boot up. To startup my off
grid Powerwall we wired in a 12V power supply to the input terminals and
plugged the other side into a grid-connected outlet.
