When PG&E goes dark,
your home doesn't.
We size your battery to run the whole house for one to three days, not a few hours.

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.
Whole-home backup is not a wiring claim. It is a runtime claim.
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. Anyone can wire a battery to your whole panel. Whether it carries the house for a few hours or a few days comes down to size. SF Standard’s reporting on the outage.
- Heat or AC
- Refrigerator and freezer
- Internet and Wi-Fi
- The EV charger
- Well pump
- Medical equipment
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. We show the range.
Battery-only or solar plus battery, we model both against your real bills and show the cost and runtime of each. You own the equipment, no lease or PPA. 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.
Questions homeowners ask about backup.
Start with your address.
Tell us where you live and roughly what you pay PG&E. We will model battery-only and solar-plus-battery backup for your house, then walk through runtime, cost, and tradeoffs on a 30-minute video call with the designer who would run your project.
