Storm outside. Lights on inside.
Every home battery we install is on sale now. When the next storm takes out the grid, your battery switches on by itself and keeps your family warm, fed and connected.
Western Washington knows what a dark winter looks like.
In November 2024 a bomb cyclone tore through the Puget Sound. Hundreds of thousands of homes lost power overnight, and some waited days to get it back.
It's not the power you miss. It's everything it runs.
Ask people what they miss most in an outage and the answers are the same: heat, internet and the fridge. Here's what a battery keeps running when the grid can't.
A warm house, all night
Even a gas furnace needs electricity to light and run its fan. When the power goes, the heat goes with it, and the house gets colder every hour. A battery keeps your furnace fan, thermostat and a warm room running so nobody's sleeping in their coat.
Food in the fridge
About 4 hours in the fridge and two days in a full freezer. After that, the groceries go in the trash. A battery keeps them cold.
Movie night goes on
Lights, TV and Wi-Fi stay on. The kids barely notice the storm, and you get to be the house on the street with the lights on.
Wi-Fi and phones
Keep working from home, keep the kids' school laptops charged, and stay reachable when family is checking in.
Water and a dry basement
On a well, no power means no water. In a downpour, a dead sump pump means a flooded basement. A battery keeps both pumps going.
Medical devices
CPAP machines, oxygen concentrators and medicine that has to stay cold. Some things can't wait for the utility crew.
No fumes, no fuel runs
Every big Northwest windstorm brings carbon monoxide poisonings from generators and grills used near the house. A battery is silent and has no exhaust.
Your own power plant, on your own wall.
You can't stop the storm or speed up the repair crews. You can decide your house won't go dark.
A storm is forecast
Storm mode tops your battery off ahead of severe weather, so it's full when you need it most.
The grid goes down
Your battery senses the outage and takes over by itself. No cords, no pull-start, no trip outside in the rain.
The sun comes back
Have solar? Grid-tied panels shut off in an outage, but with a battery they keep recharging it, day after day.
Your generator can refill your battery.
Keep the generator you own. Pair it with a FranklinWH battery and it becomes your backup's backup. The battery runs your home quietly, and the generator only fires up when a long outage really calls for it.
The grid goes down
Your FranklinWH battery takes over by itself. The generator stays off and quiet. Most outages end before it's ever needed.
All night, in silence
The battery runs your home through the night. No roar at 2 a.m., no exhaust by the window, and your neighbors stay happy.
Your generator tops it back up
When a storm knocks the power out for days, the generator starts only when the battery runs low, refills it, then shuts off again. Fewer hours, less fuel.
- Burn far less fuel
- Fewer gas runs in a storm
- Less wear on your generator
- Quiet nights, even mid-outage
Your car can refill your home battery.
Drive a Tesla? Powerwall 3 runs your home the moment the grid goes down. If the outage drags on, a Powershare-compatible vehicle plugged into your Wall Connector can share its battery and keep your home going for days.
The grid goes down
Powerwall 3 senses the outage and takes over automatically, so your lights, fridge and Wi-Fi stay on.
Your car is the backup
No generator, no fuel and no noise. The car in your garage holds more energy than most home batteries.
Your car tops it back up
Plug a compatible car into a Universal or Gen 3 Wall Connector and it shares its battery with your home through Powershare, refilling Powerwall 3 when it runs low.

Winter Battery Sale applies to home battery systems contracted with Blossom Solar by December 31, 2026; sale pricing is shown in your quote. Backup time depends on battery size, state of charge, what you choose to back up and how much energy you use. Electric heating uses a lot of energy, so most battery systems back up selected circuits rather than whole-home electric heat. Food-safety times are USDA guidance for a closed refrigerator and freezer. Outage figures from regional utility and news reports on the November 19, 2024 bomb cyclone. PSE Flex Batteries incentives are set by Puget Sound Energy, are subject to program terms and availability, and require enrollment. Storm mode availability varies by battery. Generator pairing requires a compatible generator; auto-start needs a two-wire start connection, which we confirm at the site visit. Powershare home backup requires Powerwall 3, a Universal or Gen 3 Wall Connector and a compatible vehicle; check Powershare Support on your vehicle's touchscreen.
