Home battery backup is the silent, seamless way to keep your Texas home running when the grid fails. No fuel, no noise, no engine rumbling outside your bedroom window at 2 AM. Your house just... stays on. The AC keeps running. The fridge stays cold. The WiFi never blinks.
It's genuinely this simple. No PhD in electrical engineering required.
A storm, a blown transformer, ERCOT being ERCOT—whatever the cause, the power drops.
In milliseconds—faster than you can blink—your battery system detects the outage and disconnects from the grid.
The battery powers your home. Lights, AC, fridge, WiFi—whatever circuits you've configured. No interruption.
Seriously. Most battery owners find out the power went out from their neighbors, not from their own experience.
We're brand-agnostic, but after connecting hundreds of Texas homeowners with installers, these three consistently rise to the top.
Most popular. Great all-around choice for Texas homes.

The honest answer: it depends on two things. What you want to keep running (backup scope) and how long you need it to last (backup duration). Multiply those together and you've got your battery count.
Running AC (3-ton system), fridge, lights, WiFi, garage door, and a few outlets during a summer outage:
Add solar and your batteries recharge daily—potentially giving you indefinite backup during summer outages.
Don't guess. Our free assessment calculates your exact battery needs based on your home's square footage, AC system, appliances, and how long you want backup to last. Take the 3-minute assessment →
We're not going to pretend batteries are perfect for everyone. Here's the real comparison.
The real answer? It depends on your home. A 2,000 sq ft house in Southlake with solar panels? Battery makes a ton of sense. A 4,500 sq ft ranch in Weatherford with natural gas? Generator is probably the move. Not sure? Hybrid systems give you both.
1 battery (essentials backup)
$9,000–$15,000
Lights, fridge, WiFi, a few outlets. 4-12 hours.
2-3 batteries (whole-home backup)
$18,000–$35,000
Everything including AC. 12-24+ hours.
With solar integration
$25,000–$50,000+
Battery + solar panels. Indefinite backup in summer.
If your battery charges from solar (even partially), the entire system qualifies for a 30% tax credit through 2032. On a $30,000 battery system, that's $9,000 back on your taxes.
Always consult a tax professional. But this credit is real, substantial, and available right now.
A note about Base Power's "$695 batteries": You may have seen ads for batteries at $695. That's a VPP (virtual power plant) subscription model—you're essentially leasing a battery and becoming their electricity customer. It's a different product entirely. The prices above are for batteries you own outright with no ongoing commitments.
It depends on what you're running. A single Powerwall (13.5 kWh) can power essential circuits—lights, fridge, WiFi, phone chargers—for 10-24 hours. If you're running the AC, that drops to 4-8 hours depending on your system size and outdoor temperature. Most Texas homeowners who want whole-home backup go with 2-3 units.
