Powerwall and EV charging

[bart513]

Is it possible to charge my MS directly from the PW without having solar panels?

There are a number of threads around this, but basically why would you? The Powerwall is tiny by comparison, and you lose 10% by putting it into the Powerwall before charging...

Yes.

Can you please share how I can do that?
Thx so much

I have 3 PWs that act as back up generator if the power goes out. Most of the time they’re storing energy so I thought it might be more cost effective

a wall connector wired into your backup panel

What I do is plug the car into the dryer outlet.

I usually charge the car from the grid. My wall connector is not backed up by the PW, nor is it measured by the PW. Charging the car from the PW for me would only be in the unlikely event of needed to charge the car during grid outage. But the plan in that case is to back the car into the garage so the cord will reach to the dryer outlet. With only 1 PW, I might need to decrease the car charging amps to avoid drawing more than PW can handle.

I do have solar, and the PW has allowed us to keep the lights on during a couple of multi-day outages. It hasn't happened since we got the Model Y, though, so this is mostly a contingency plan. Still, a full charge of the car would take 4 days of summertime solar...

I plug into the dryer plug as well
