A home battery in the USA costs $11,500–$18,500 installed in 2026 for one 13.5 kWh unit such as a Tesla Powerwall 3, and most homeowners pay about $14,750. Whole-home backup adds a gateway ($1,000–$3,500), and bigger homes often need two batteries ($16,500–$34,000). There is no federal tax credit left for batteries installed in 2026.
$11,500–$18,500 installed for one 13.5 kWh home battery such as a Tesla Powerwall 3, $14,750 typical. Budget $16,500–$34,000 for two batteries and whole-home backup. Pick your city ↓
- One 13.5 kWh battery (Tesla Powerwall 3 class), installed: $11,500–$18,500, $14,750 typical
- Whole-home backup gateway adds $1,000–$3,500; two batteries run $16,500–$34,000
- The federal 30% battery credit ended for expenditures after December 31, 2025
- Panel upgrade if needed: $1,500–$4,500; 20–24 kW standby generator for comparison: $8,500–$16,000
- Pick a city below for local prices across 195 US metros
Prices below come from marketplace quote data, installer and manufacturer pricing, utility program pages and city permit schedules across 195 US metros, re-verified in November 2026. They are before any utility or state incentive. Pick your city for local pricing.
One battery runs $11,500–$18,500 installed across the US, and the battery itself (about $8,200–$10,000 for a Powerwall 3) is the same price everywhere. The rest is labor, backup equipment, panel work and permits, which is why a battery in Boston or Atlanta costs more than the same battery in Phoenix or Las Vegas. All prices are before incentives and sales tax where it applies.

| Two batteries — 27–30 kWh | $16,500–$34,000 installed | Larger homes, central AC, well pumps, longer outages |
| Portable power station + transfer panel — about 4 kWh | $4,000–$7,500 installed | A few circuits for a few hours; check the warranty term |
| Standby generator, 20–24 kW (comparison) | $8,500–$16,000 installed | Outages that last days; runs on natural gas or propane |
Per kWh, Tesla is the cheapest of the big brands in EnergySage's 2026 quote data at about $967 per kWh, against $1,232 for FranklinWH, $1,429 for Enphase and $1,532 for SolarEdge. Warranty length is the other big difference: 10 years on Powerwall 3 and SolarEdge, 15 years on Enphase and FranklinWH.
Common Home Battery Jobs and What They Cost (2026)
Most battery jobs take one day on site; whole-home systems and panel upgrades take two. A single battery with partial backup runs $11,500–$18,500.
| Block or rate | Low | Typical | High |
|---|---|---|---|
| One battery, partial backup (about 1 day) | $11,500 | $14,750 | $18,500 |
| One battery with a whole-home gateway (1–2 days) | $12,500 | $16,550 | $22,000 |
| Add an expansion unit during the install (an hour or two extra) | $5,000 | $6,500 | $8,000 |
| Two batteries, whole-home backup (1–2 days) | $16,500 | $23,000 | $34,000 |
| Add a battery to existing solar (about 1 day) | $12,000 | $15,250 | $19,500 |
| Add a critical-loads subpanel (4–8 hrs) | $400 | $1,000 | $1,750 |
| Upgrade a 100A panel to 200A (1 day, plus a utility visit) | $1,500 | $2,500 | $4,500 |
| Install a generator interlock and inlet (2–4 hrs) | $400 | $620 | $850 |
| Install a 20–24 kW standby generator (1–2 days) | $8,500 | $11,500 | $16,000 |
| Battery service or re-commissioning visit (1–3 hrs) | $150 | $350 | $800 |
Time on site is short; the wait is the paperwork. Permits, inspection and the utility's permission to operate (if the battery ties into solar) usually take longer than the install itself.
Home Battery vs Standby Generator vs Portable Generator
Three ways to keep the lights on. The right one depends on how long your outages last and whether you want the backup to pay you back.
| Factor | Home battery | Standby generator | Portable generator |
|---|---|---|---|
| Upfront cost, installed | $11,500–$18,500 for one 13.5 kWh battery | $8,500–$16,000 for 20–24 kW | $400–$850 for the interlock or transfer switch, plus the generator |
| Fuel and running cost | No fuel. Refills from solar or the grid | About $30–$120 a day in fuel at typical loads, up to $220 a day for a 16–22 kW unit running hard (natural gas or propane) | Gasoline you buy, store and pour in by hand |
| Noise | Silent | Engine noise whenever it runs, plus regular self-tests | Loud. Must run outdoors, away from doors and windows (carbon monoxide) |
| Maintenance | Little: app monitoring, no scheduled service | $150–$300 a year for routine service (oil, filters, battery check) | Oil changes and fresh fuel, done by you |
| How long it covers you | Hours to a day or so per 13.5 kWh; longer if solar recharges it | Days to weeks, as long as gas or propane keeps flowing | As long as you keep refueling it |
| Permits | Electrical permit, often a building or fire review; utility approval if tied to solar | Electrical and gas permits; some towns check setbacks | Electrical permit for the interlock in most places |
| Pays you back? | Can: time-of-use savings and utility battery programs | No | No |
A battery if you have solar, time-of-use rates or a utility program that pays for batteries, and outages are short. A standby generator if you lose power for days at a time and have natural gas. A portable generator and an interlock if you want cheap insurance and do not mind running it yourself.
Upkeep, Payback and What a Generator Costs to Run
Batteries cost little to keep, and in some places the utility pays you to own one. These are the yearly numbers next to a generator's.
| Item | Low | Typical | High |
|---|---|---|---|
| Battery running cost, per hour of backup (no fuel) | $0 | $0 | $0 |
| Battery scheduled maintenance, per year | $0 | $0 | $0 |
| Battery service visit after the warranty | $150 | $350 | $800 |
| Time-of-use bill savings from one battery, per year (example) | $0 | $821 | $1,300 |
| ConnectedSolutions payment, per kW of summer events (MA, RI) | $225 | $234 | $275 |
| Standby generator fuel, per hour of running (the per-day figure ÷ 24) | $1 | $5 | $9 |
| Standby generator fuel, per day of a full outage | $30 | $120 | $220 |
| Standby generator routine maintenance, per year | $150 | $250 | $300 |
Program payments vary the most: ConnectedSolutions paid $225–$275 per kW in Massachusetts and Rhode Island (rates as of February 2025). Time-of-use savings depend on your rate plan; one national cost analysis's example works out to about $821 a year. Ask your installer to show the savings with your own bills.
What affects home battery costs
How much of the house you back up
Partial backup on a backup switch is the cheapest job. Whole-home backup adds a gateway ($1,000–$3,500) and often a second battery ($9,000–$12,500).
Your electrical panel
A crowded or 100-amp panel is the most common add-on: $1,500–$4,500 to go to 200 amps, or $400–$1,750 for a critical-loads subpanel.
Brand and capacity
Tesla prices lowest per kWh among the big brands; Enphase and SolarEdge highest. FranklinWH's 15 kWh aPower 2 costs more but stores more.
Where it goes and the code
Model codes (IRC R328, NFPA 855) keep batteries out of bedrooms and living space, limit each unit to 20 kWh, cap garages at 80 kWh and utility closets at 40 kWh, and call for impact protection where a car could hit it.
Your city
EnergySage's November 2026 local quotes ran from about $807 per kWh in Phoenix to $1,480 in Boston across the 17 metros we checked. The hardware is priced nationally; labor and competition are local.
Incentives where you live
No federal credit is left for 2026 installs. California (SGIP), Massachusetts and Rhode Island (ConnectedSolutions), Connecticut (Energy Storage Solutions) and New York (NYSERDA) still pay toward batteries, and many utilities run their own programs.
How to save on home battery
- Get two or three bids.The same Powerwall 3 is quoted thousands apart. The battery costs the installer the same; the labor and add-ons are where bids differ.
- Back up the essentials.A critical-loads subpanel ($400–$1,750) keeps one battery on the fridge, furnace and Wi-Fi. A second battery costs $9,000–$12,500 more.
- Add storage at install time.An expansion unit added with the first battery is $5,000–$8,000, far less than a second battery installed later.
- Join a utility battery program.ConnectedSolutions in Massachusetts and Rhode Island paid $225–$275 per kW for summer peak events (as of February 2025). Ask your utility whether it pays for batteries.
- Bundle the panel work.A panel upgrade done in the same job shares the permit, the inspection and the utility visit.
- Pick the warranty, not just the price.Ten years at 70% (Powerwall 3, SolarEdge) vs fifteen years (Enphase, FranklinWH) is a real difference for a $15,000 purchase.

Home Battery Cost in the USA by Backup Level
Essentials backup on one battery is $11,500–$18,500, whole-home backup with a gateway is $12,500–$22,000, and two batteries for a larger home are $16,500–$34,000.
Worked example: one Powerwall 3 at $14,750 plus a whole-home gateway at $1,800 is $16,550. If the house has a 100-amp panel, add $2,500 for the upgrade: $19,050.
A larger home that wants central AC on backup usually needs two batteries ($23,000 typical) plus the gateway, about $24,800. EnergySage puts full whole-home backup at about $34,000 in its 2026 quotes.
What a home battery quote should include
A real battery quote answers all of these. If it answers fewer than six, ask before you pay a deposit.
- Battery brand, model and usable kWh
- Backup type: partial (backup switch or subpanel) or whole-home (gateway)
- Any panel upgrade or subpanel, priced as its own line
- Where the battery mounts, and any bollards or heat alarm the code needs
- Permit, inspection and utility interconnection fees
- Warranty: years, capacity guaranteed at the end, and who services it locally
- Monitoring setup and utility program enrollment
- Payment schedule and what happens if utility approval is delayed
- Sales tax where it applies, and the license number of the electrician doing the work
Home battery cost: FAQ
How much does a home battery cost in 2026?
$11,500–$18,500 installed for one 13.5 kWh battery such as a Tesla Powerwall 3, with $14,750 typical. Whole-home backup with two batteries runs $16,500–$34,000.
Is there still a federal tax credit for home batteries?
No. The 30% Residential Clean Energy Credit (which covered batteries of 3 kWh or more) ended for expenditures made after December 31, 2025, under the July 4, 2025 tax law. The IRS treats the expense as made when installation is complete, so a battery finished in 2026 does not qualify even if you paid in 2025.
How much is a Tesla Powerwall 3 installed?
About $14,750, within $11,500–$18,500. The battery itself is about $8,200–$10,000; the rest is labor, backup equipment and permits. An expansion unit adds 13.5 kWh for $5,000–$8,000.
How many batteries do I need to run my whole house?
One 13.5 kWh battery covers the essentials for hours to about a day. Running central AC or an electric range usually takes two ($16,500–$34,000), plus a whole-home gateway ($1,000–$3,500).
Is a home battery cheaper than a standby generator?
Upfront they overlap: a 20–24 kW standby generator is $8,500–$16,000 installed against $11,500–$18,500 for one battery. A generator runs for days on gas; a battery is silent, needs no fuel and can earn money in utility programs.
Can I add a battery to my existing solar?
Yes. An AC-coupled battery works next to your existing inverter for about $12,000–$19,500 installed. Check whether your utility needs a new interconnection application.
Do I need solar to have a home battery?
No. A battery can charge from the grid and still give you backup, for about $11,500–$18,500 installed, the same as a battery installed with solar. EnergySage puts the average 13.5 kWh install at about $15,650 with or without solar.
Can a home battery go in my garage?
Usually, yes. Model codes allow up to 80 kWh in a garage, keep batteries out of bedrooms and living space, and call for a heat alarm and impact protection (such as bollards) where a car could hit the unit. Your city's code decides.
Which states still pay for home batteries?
California (SGIP, with a $1,100 per kWh equity budget open since June 2, 2025), Massachusetts and Rhode Island (ConnectedSolutions, $225–$275 per kW as of February 2025), Connecticut (Energy Storage Solutions: since April 1, 2026 a $30–$130 per kWh enrollment payment plus $300–$550 per kW a year for peak performance) and New York (NYSERDA, $200–$250 per kWh, $450 for lower-income homes, as of September 2026). Rules change often, so check before you sign.
What's the average home battery price in 2026?
About $14,750 installed for one 13.5 kWh battery, the middle of the Powerwall 3 prices in the national price guides and installer data we checked. EnergySage's own first-half-2026 average for 13.5 kWh, across all brands, is $15,647.
