After Uri in ’21 and the May ’24 derecho, Texans know the grid isn’t a backup plan. A home battery is. We match you with one TDLR-licensed installer who specializes in your utility territory.
Submit the form. A representative reviews your home and utility (Oncor / CenterPoint / AEP / municipal) and checks your retail electric plan. They call you within two business days with one vetted home battery installer match. We don't sell your information to anyone else.
Rather talk it through first? Call (949) 516-4214.
Address, contact, and why you want a home battery. Two minutes, on this page.
A real person checks your service area, your home's electrical profile, and which home battery fits best.
You get one home battery installer. The one we’d call if it were our own house.
No obligation. Compare to any quote you already have. We don’t profit on the install.
Most Texas “solar lead” sites sell your number to a half-dozen home battery installers, then to a half-dozen more if you wait a week.
We’ve toured the warehouses. We’ve audited the city-permit records in Dallas, Houston, Austin, San Antonio, and Fort Worth. We make one call to one Texas home battery installer who knows your AHJ. The relationship stays with us until your battery is on the wall.
We only match homeowners with home batteries we’d put in our own walls. The market changes every quarter. These are the brands earning their place in 2026.
Best integrated inverter on the market. Heavy but bulletproof.
Modular and microinverter-native. The right call for retrofit on Enphase solar.
Largest single unit. Great for whole-home backup without stacking.
German engineering, 15,000-cycle warranty. The premium pick.
Domestic assembly, US warranty support. Newer brand, watching closely.
New chemistry every quarter. Ask us what we’re testing right now.
We launch Texas home battery service in a county only when we’ve found installers we’d trust with our parents’ house. As of May 2026, 162 of Texas’s 254 counties have a vetted match. That covers every major metro plus most of the Hill Country and East Texas.
Not in Texas? Visit our California site or our national page. We’ll notify you the week we open home battery service in your state.
Texas has the highest per-capita home battery adoption in the country. The grid history below explains why. A home battery doesn’t fix ERCOT, but it keeps your home running when ERCOT can’t.
Roughly 5 million Texans lost power for up to nine days. Estimated 246 deaths attributed to the outage. Gas-fired generation froze; ERCOT came within minutes of catastrophic grid collapse.
About 900,000 CenterPoint customers lost power when straight-line winds tore through Houston metro. Some areas were dark for 14+ days in 95°F+ heat.
Multiple Energy Emergency Alerts as summer demand approached available supply. Voluntary conservation requests went statewide.
Lighter than Uri. Hardened-grid investments held in most regions, but rolling blackouts still hit Hill Country and parts of East Texas for several hours.
East Texas and the Coastal Bend saw widespread outages. CenterPoint and Entergy took up to a week to fully restore service in worst-hit communities.
We have vetted TDLR-licensed home battery installers serving every major Texas metro plus most of the Hill Country, East Texas, and Rio Grande Valley. The list below is grouped by region. If you live in any of these counties, we have a match for you today.
Nothing. The installer pays us a flat referral fee. That fee is the same whether you buy a $9,000 home battery or a $24,000 stack, so we have no incentive to upsell you.
No. Your information goes to one home battery installer (the one we match you with) and nowhere else. No marketing partners, no resellers, no follow-up “you’ve been pre-approved” calls.
Great. Send it over. We’ll either confirm it’s a fair deal or tell you where it’s off. No charge either way.
Your home’s electrical service, your reason for backup, your existing solar (if any), and your roof or wall layout. The right answer is rarely the biggest box.
No. We are a private company, WattKeeper LLC doing business as Solar Battery USA. We are not a government program, a utility, or a state agency.
A human reads your application within two business days, calls you to confirm the details, and emails one home battery installer match with an introduction. You take it from there or you don’t.
A single-unit home battery typically runs $9,000 to $17,000 installed for a 10-15 kWh system, before incentives. A whole-home stack of two or three units runs $20,000 to $35,000. The 30% federal tax credit through 2032 takes thousands off the real cost, and state rebates (SGIP in California) can drop it further. We match you with an installer who’ll give you a written quote. There are no fees on our end.
Most modern home batteries use LFP (lithium iron phosphate) chemistry and come with 10- to 15-year warranties. They’re rated for 4,000 to 15,000 charge cycles. Real-world expectancy is 10-15 years of useful life before significant capacity loss. Sonnen’s evo carries a 15,000-cycle warranty, the longest in the category. Tesla’s Powerwall 3 and FranklinWH’s aPower 2 both come with 10-year warranties.
Yes, if it’s installed correctly. A “grid-tied” battery without backup configuration shuts off during an outage for utility-worker safety. A properly-installed battery with a critical-loads panel or whole-home transfer switch will island your home from the grid and keep your circuits running. Every installer we match you with has done islanding-mode commissioning on the chemistry they’re recommending.
Yes, if it’s installed correctly with a properly-sized critical-loads panel. We only match you with installers who’ve done islanding-mode commissioning on the chemistry they’re recommending, and we confirm your home has the right transfer-switch configuration before the introduction. A battery that can’t island during an outage is just an expensive UPS.
No. Texas doesn’t have a statewide battery incentive program comparable to SGIP. Federal tax credits (Inflation Reduction Act, 30% of system cost) still apply, and a few utilities including Oncor and CPS Energy have time-limited rebate programs. Your installer will know which rebates apply to your specific utility and home. We vet them on that knowledge before sending you their way.
For overnight plus a critical-loads panel (fridge, lights, internet, plugs, a few rooms with mini-splits), a single 13.5 kWh battery is usually enough. For whole-home backup including a 4-ton central AC during a multi-day Texas summer outage, you need a stack of 2 or 3 batteries (27 to 45 kWh total) and a whole-home transfer switch. Your installer sizes this based on your specific home and load profile.
Oncor (DFW and Central TX) and AEP Texas (West TX and the Coastal Bend) both move quickly on home battery interconnect, typically 2 to 4 weeks from application to permission-to-operate. CenterPoint (Houston) and CPS Energy (San Antonio) take a bit longer, generally 4 to 8 weeks. Municipal utilities like Austin Energy and Garland Power & Light vary. Your installer handles all paperwork.
Yes, with proper sizing. A single home battery can run a 1-ton mini-split AC for 8 to 12 hours. Running a 4-ton central AC requires a 2- or 3-battery stack (27 to 45 kWh) AND a soft-start kit on the AC compressor to handle the inrush current. We confirm AC compatibility during application review. Every installer we match you with has done summer-outage commissioning in Texas.
You won't get spammed with calls from multiple installers, and we don't sell your number to anyone else. A home-battery expert reviews your application and introduces you to one vetted licensed installer in your state.
