A 57.2 kWh stack in a Bay Area garage.
Two FlexBoss 21 inverters and four EG4 batteries: double our standard package, for a homeowner who wanted more runtime.
Anyone can wire a battery to the whole panel. The difference is how long it runs.
Outages here run for days now. A December 2025 fire at PG&E’s Mission substation left about 130,000 San Francisco homes dark for up to 48 hours, and PSPS shutoffs hit the hills every fall. Whether a battery carries the house for a few hours or a few days comes down to size. SF Standard’s reporting on the outage.

- Refrigerator and freezer
- Internet and Wi-Fi
- The EV charger

Proof from a real outage. Just ask Andres.

“Production is right where they said it would be, and we've already had a PG&E power outage where the whole-home battery backup worked flawlessly.”
Cost depends on runtime. See yours.
Enter your address and we size the battery to the runtime you want, then price it against your real usage. No contact info needed to see your number.
No PPAs, no monthly payments. Battery-only or solar plus battery, we model both and show the cost and runtime of each. If the numbers do not pencil, we tell you.

Cleaner than a generator. Useful more often.
No fuel to store, no annual service, no noise, no carbon monoxide. And unlike a generator that sits idle 364 days a year, a battery paired with solar works every day, storing your daytime production and running the house in the evening instead of buying power back from PG&E at peak rates.
The hardware is open and yours, so you can add a generator, a fuel cell, or more capacity later, on your terms.
The outage is the moment you notice it. The daily use is what helps pay for it.
