Tesla Powerwall

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.

Tesla has issued a recall for its Powerwall 2 battery units sold between November 2020 and June 2022 over a potential risk of battery fire.

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?

Whether it’s to keep the lights on after a natural disaster or just to avoid peak energy rates, more people than ever are adding battery energy storage to their home solar systems. With some 45% of home solar customers saying yes to home batteries last year, the big question isn’t whether or not to get one – it’s what kind to get.

Two options stand out: lithium ion, and vanadium flow. Here’s the information you need to make the right choice.

Hurricanes, wildfires, and triple-digit heat domes are stressing America’s energy grid like never before, with millions experiencing rolling blackouts and brownouts as they struggle to keep their collective cool. As rooftop solar and home batteries show up in more and more places, however, we’re building something bigger than a backup: a virtual power plant that can keep things running when the grid can’t.

Tesla has announced that it produced its one millionth Powerwall. An impressive milestone that is, unfortunately, overshadowed by some questionable math.

New data suggests that the Tesla Powerwall 3 is significantly disrupting the US solar inverter market.

The home battery pack’s integrated inverter is changing the game.

The US battery storage market set another record in 2024, installing 12.3 gigawatts (GW) of new capacity across all sectors, according to a new report from the American Clean Power Association (ACP) and Wood Mackenzie.

In total, 12,314 megawatts (MW) and 37,143 megawatt-hours (MWh) of energy storage were added, marking a jump of 33% and 34%, respectively, compared to 2023.

On today’s exciting episode of Quick Charge, we’ve got the Vistiq! It’s all-new, three row SUV from Cadillac that packs 650 hp and can go from 0-60 mph in under 3.5 seconds, a serious word from Rivian, and something fishy at Tesla.

Tesla has launched its new Powerwall 3 expansion units that can slash installation times by roughly half.

After decades of stable electricity demand in the US, a new report from ICF (Nasdaq: ICFI) predicts a significant surge starting this decade.

Octopus Energy and Tesla’s new partnership means Octopus can install Powerwalls and give its customers with Powerwalls better price tariffs.

Tesla Energy and smart electrical panel maker SPAN have launched the SPAN + Tesla Powerwall 3 bundle, a smart home battery backup system.

Tesla has released more details about Powerwall 3, its new generation home energy storage system, and there’s some more good news.

Here are three standout rooftop solar trends that emerged in 2023 – and how they impact consumers who want to switch to clean energy.

Tesla has started to take orders for the new Powerwall 3 in the US and Elon Musk revealed that the new home energy storage system has an insane peak power output of 30 kW.

Connecticut’s home battery storage program, Energy Storage Solutions, just doubled its upfront incentive to help homeowners invest in backup power – here’s how it works.

Ecoflow announced the Delta Ultra today at CES, its monster 6kWh home LFP battery pack on wheels. Its 240V/30A= 7.2kW output can back up a home the way a whole home generator or Tesla Powerwall can. However, this thing has wheels and can be loaded into a vehicle to be transported to a campsite or a remote location. EcoFlow provided us with one last month and we’ve taken it to an off-grid tiny home which it kept powered, even in the cold of winter, for a whole weekend. Let’s have a deeper look…

Is Rivian planning its own home energy system like the Tesla Powerwall? The EV maker’s recent patent for an Energy Storage Device hints one could be coming.

Tesla has released a new comparison report claiming Powerwall with solar is cheaper than a traditional backup generator.

Tesla announces that it achieved the milestone of having deployed 1 GWh of Powerwalls in Europe.

Its energy storage business is becoming a major division.
