Home Battery Guide
Home Batteries, Explained Without The Sales Pitch
A home battery can keep your lights on in an outage and shift when you use power. It is not right for every house. Start with the basics, then compare quotes from local installers.
What A Home Battery Can Do
Backup Power
Runs the circuits you choose when the grid goes down. How long it lasts depends on battery size and what you plug in.
Time Of Use Savings
If your utility charges more in the evening, a battery can charge when power is cheap and supply the house when it is not.
Store Your Own Solar
With panels, a battery keeps extra daytime power for the evening instead of sending it all to the grid.
Questions To Settle Before You Get Quotes
- Do you want backup for the whole house or only a few key circuits?
- Does your utility offer time of use rates or pay less for exported solar?
- Do you already have solar, and who installed it?
- Do you own the home, and is your electrical panel in good shape?
Your answers change both the size you need and the price. Our guides walk through each one.

How To Compare QuotesCommon Questions
Do I need solar panels to get a home battery?
No. A battery can charge from the grid. Solar makes the battery more useful, and programs set their own eligibility rules, so read the terms. See Battery Without Solar.
How long will a battery run my house?
It depends on the battery capacity in kilowatt hours and your load. A battery sized for a few essential circuits can last many hours. Running central air conditioning or an electric dryer drains one quickly. See Battery Sizing.
Is there a federal tax credit for home batteries?
The IRS says the Residential Clean Energy Credit, which covered battery storage of at least 3 kilowatt hours, is not available for property placed in service after December 31, 2025 (IRS page checked October 2026). A battery installed in 2026 does not qualify for it. Confirm your situation with a tax professional. State, utility, and local programs may still exist. See Incentives.
