Meet Powerwall 3.
A smarter way to store energy and keep your home running. Solar inverter and home battery in one integrated unit — engineered by Tesla, sized and installed for your home by Volt Home.
Automatic backup
Detects an outage and switches over on its own — no generator to start, no fuel to store.
Whole-home protection
11.5 kW of continuous power and 185 LRA motor start — enough to run the systems most homes depend on.
Solar integration
Accepts up to 20 kW of solar with the inverter built in, so the energy your panels make by day powers your evening.
Smart energy management
See production, storage and use in the Tesla app, and set how your system behaves day to day.
When the grid goes down, your home stays on.
Powerwall 3 detects an outage and can power your home automatically — the lights stay on, the fridge keeps running, and the storm outside stays outside.
No switch to flip and nothing to start. Backup begins on its own.
Built for hurricane season in Florida and grid events in California.
Paired with solar, Powerwall refills during the day — outage after outage.
Which circuits stay on — and for how long — depends on your home's energy use and how many Powerwalls you install. Your Volt Home designer maps it out with you.
Store energy.
Use it when you need it.
Your system produces energy, keeps what you don't use, and gives it back when the sun is down or the grid is out.
Daytime — your solar produces more than the house needs. The extra energy charges Powerwall instead of leaving your property.

Powerwall 3, answered.
Powerwall 3 is Tesla's home battery — a wall-mounted unit that stores electricity so your home can use it later. It stores 13.5 kWh of energy and includes a solar inverter built in, so a single unit can both convert solar energy and store it. It can be installed with new solar, added to an existing system, or installed on its own for backup power.
Often, yes. Each unit stores 13.5 kWh and delivers 11.5 kW of continuous power, and can start motor loads rated up to 185 LRA — enough for the air conditioning in most homes. Larger or all-electric homes may need two or more; systems scale to four units. Volt Home sizes it with you during the consultation, based on your utility bill and the circuits you want backed up.
Powerwall detects the outage and switches your home over to stored energy automatically — there's nothing to start or switch by hand. When the grid comes back, it switches back on its own. Paired with solar, Powerwall recharges during the day, so it can keep going through multi-day outages.
Yes — and it's designed for it. Powerwall 3 accepts up to 20 kW of solar input with the inverter integrated into the unit, which simplifies the system. Energy your panels produce and your home doesn't use charges the battery instead of being exported, so you can use it after sunset.
The unit is wall-mounted by a certified crew and wired into your electrical service, typically with a Tesla Backup Switch or Gateway. On-site work is usually one day for a battery installation, or one to two days paired with new solar. The overall timeline depends on permitting and utility approval in your city — Volt Home handles all of it and keeps you updated.
Yes. We work with several financing partners and offer flexible options, including $0-down plans with approved credit. Your specialist will walk through what's available for your home and market, including any state or utility programs you may qualify for.
Power your home with confidence.
