Tesla Powershare in Florida: Can Your Tesla Power Your Home After a Hurricane?

The storm moved through overnight, and by morning the wind has finally dropped. The power is still out across most of Lee County, though, and the utility is talking about days, not hours. The house is already getting warm and sticky. Out in the garage, your Tesla sits on a full charge.

That car can do more than get you to the gas station that isn't open yet. With Tesla Powershare, the battery in your vehicle can send electricity back into your home during an outage. Here's how Tesla Powershare in Florida can serve as hurricane backup power, what you need to set it up, and how it fits alongside solar and a Tesla Powerwall.

Normally, power flows from your house into your car. Powershare reverses that flow, turning an eligible Tesla into a large rolling battery. Tesla describes it as a bidirectional charging system that can power your home, along with tools, appliances, or another EV.

For home backup, the system watches the grid for you. When an outage hits, Powershare detects it and lets the vehicle start supplying your home automatically, as long as the car is plugged into a Tesla Wall Connector or Universal Wall Connector.

Florida outages after a major hurricane don't always clear up by dinnertime. When lines and poles come down across a region, restoration can stretch across several days, which is when a big battery on wheels matters most.

On its own, a fully charged Cybertruck can keep a home running for over three days, by Tesla's estimate. That figure assumes a home using about 30 kWh per day, so your result will depend on how much power you draw.

Air conditioning is the biggest variable here. Cooling an entire Florida home in September heat can drain a battery much faster than lights, a refrigerator, and a few fans. Many homeowners stretch their backup by cooling just one or two rooms, closing off the rest of the house, and saving the oven and dryer for after the grid returns.

Coastal Energy is Tesla Certified across that full lineup, from solar panels and Tesla Powerwall to EV charging, so one team can design the whole system to work as a unit. Tesla's figures come from its Powershare page.

Every Cybertruck supports Powershare today. Tesla has since expanded eligibility: any new Model 3 or Model Y with an order date of October 1, 2026 or later qualifies, along with a number of earlier builds.

The equipment depends on what's already at your home. Homes with a Powerwall 3 and a Tesla Wall Connector don't need anything extra, and Tesla lists Powerwall 2 and Powerwall+ compatibility as coming soon. Cybertruck owners without a Powerwall need a Powershare Gateway and a Universal Wall Connector. Tesla puts the hardware at around $1,950. Installation is quoted per project, since your final price depends on your electrical panel and setup.
