Off grid solar powered mega 168 Tesla V4 Superchargers opened in Lost Hills, CA

[4sallypat]

This is certainly exciting for those that travel the I5 corridor from Nor Cal and So Cal.

Opened July 4th - half (84) are open and operational!

This Supercharger location is off grid / solar powered which means it's not tied to the power grid - making it perfect for grid down (power outage) situations.

Since I drive that way, I will be stopping by to try it out.....

But currently it says it is temporarily off line ?

Has anyone installed a home, off-grid solar charging system for an EV?

Wouldn't that just be an EVSE connected to a normal off-grid solar setup?

That is very cool.

But currently it says it is temporarily off line ?

I had read that only some units were online at this point; maybe that status is conflating the whole site with the as yet unimplemented units? Plug share shows a check in on the 5th.

I think @markboris fits that description. His house is mostly off-grid. ??

FWIW my Emporia EVSE can throttle to only use my excess solar production (which is about 6-8kW on a sunny day: I have 20x400w panels). That’s “off-grid.”

It's been 4+ years since I've had to pay PG&E. When I only had solar, which is a 15.5KW system that peaks for about 3 hours per day at 11.4KW, I could easily run the house which has 3 A/C units, hot tub, 2 EV chargers, etc. However I wasn't happy having to use PG&E in the evenings or in bad weather so I installed Tesla Powerwalls to run the house when there is no solar production. Since then, I've had a $400-$1200 credit each year at true-up.

I have two Emporia chargers (one on each side of the garage) and I also have them setup to charge on excess solar. Unfortunately, sometimes I need to charge when there is no solar production (in the evenings or winter with cloudy weather) so then I use the stored solar power from the Powerwalls. That is what I call "off-grid". ?

The temporary closure may mean the whole site is down for everyone, or that only Tesla's can charge because of the total number of stalls available is below a certain threshold. Ran into this problem in Northridge, CA last month. Non-teslas couldn't charge, but Teslas could. Previously the site was open to everybody (which is why I picked it).

I have my doubts that the site is 100% off-grid.

Could someone hop over and check?

This new station sounds great. I am driving San Diego to Oakland in three days. I hope to scope it out and report back.

I'm on the grid, but my system can run the whole house "off grid" during late spring/summer/early autumn.

Got my Rally at the end of March, and thus far have been able to keep it charged exclusively from solar energy.

If this had been 3-weeks ago, I would've checked it out. But no more SF to LA kamikaze runs for us until January.

This article explains things a bit better:

There's a 1.5 MW feed from the grid, but the majority of charging is supported by the 11 MW of solar, plus the battery backup (size unspecified).

So no, not totally off-grid. I'll be interested to see how well things work during the winter holidays after 3-days of rain and little solar production.

I'd like to see if there was a grid down statewide event if I can still charge since most of the power comes from solar and batteries.....

That would make the ICE drivers incredibly jealous while they could not fill up at gas pumps
