home battery

Base Power has just unveiled Core, a supersized 39.2-kWh home battery that it says can keep a house running for up to 36 hours and be installed in under an hour.

Lithium-ion has long dominated home battery storage, but sodium-ion is starting to make its move. Sodium-ion battery startup UNIGRID has shipped the first units of its Na+Casa residential battery, with the first systems now installed in homes across Europe.

Ava Community Energy’s SmartHome Battery program is offering income-qualified North California residents up to $6,000 in up front incentive cash to install a FranklinWH smart battery and connect it to the utility’s virtual power plant (VPP).

Home batteries are getting a lot of attention lately, but are people really looking for a full “whole home” setup, or are they just interested in keeping their phones alive for some post-hurricane doom scrolling? We asked you, our brilliant Electrek readers, what you were looking for in your home battery. Here’s what you said.

On today’s totally true episode of Quick Charge, Fred returns from the Beijing Auto Show with a fresh look at the future of the car business, and a test drive in a 2nd generation Xiaomi SU7 does nothing to convince him that China hasn’t just set the bar even higher.

California senate bill 913 would allow utilities and grid operators to treat home backup batteries like real power plants, opening the door for programs that can pay homeowners to share excess energy capacity during peak demand.

On today’s charged up episode of Quick Charge, we’ve got FranklinWH co-founder and CEO Gary Lam here to talk us through some of the benefits of a home battery system, and what it takes to make the most of one – with, or even without a home solar panel system.

Almost everyone positions home solar panel systems with home batteries as backup grid power insurance – and while that can be vitally important in a whole host of “what if” scenarios, keeping the lights on is the LEAST interesting thing your home battery can do.

18APR2026: I forgot the best one!

You’ve finally got the full trifecta – a rooftop solar panel system feeding a home backup battery that charges your EV. Heck, you’ve even got a bidirectional EV that can send power back to the house when you need it. Now the real question: are you actually saving any money?

Vermont utility Green Mountain Power is expanding one of the country’s most exciting virtual power plant programs, adding a new battery lease program to its menu of home energy offerings that lets customers add backup power at little to no upfront cost.

The new PWRcell 2 Energy Storage System from Generac has earned the prestigious 2025 GOOD DESIGN Award, recognizing the brand’s home battery products for their stand out design, functionality, and sustainability.

Net metering — the ability to sell excess electricity back to the grid for fun and profit — has helped make rooftop solar panels the centerpiece of the home energy transition for more than a decade. But, as net metering rules change and electricity prices keep climbing, the value proposition isn’t as clear as it once was. Instead of sending extra power back to the grid, homeowners are increasingly deciding that it makes more sense to hold on to that excess power for themselves.

NOTE: since most of the US is currently getting hit with a huge winter storm, I’m republishing this list of home batteries as a reminder to be prepared for the next one – particularly for folks who are looking at hours or days without power.

For years, Tesla Powerwall has been the go-to recommendation for homeowners looking for a painless, low-effort experience from their first home solar and battery backup solutions. But with a recent recall on more than 10,000 home batteries over fire safety concerns following a year (or more) of CEO Elon Musk’s political antics, more and more people are beginning to look for alternatives to the trailblazing Tesla tech. The good news: there are plenty of other great home solar battery solutions are there!

Rather than straining the grid, the batteries in EVs can actually help to stabilize the energy grid under heavy loads. PG&E gets that, and to encourage participation in its growing V2G programs, the utility is offering GM Energy customers in its territory up to $4,500 toward qualifying home battery systems.

The US battery storage market just had its biggest quarter ever. In Q2 2025, a record 5.6 gigawatts (GW) of new capacity came online, according to the latest US Energy Storage Monitor report from the American Clean Power Association (ACP) and Wood Mackenzie.

The storm hit. The power’s out. With all the damage around you, it looks like you might be without power for a few days (at least). But you planned for this. You have a home backup battery. What happens now?

Sunrun is putting tens of thousands of home batteries to work in Puerto Rico as the island’s electric grid faces a summer of high temperatures and energy shortfalls.
