Can My EV Back Up My House During a Power Outage?
That battery in your driveway might be more powerful than you think.
The answer is yes — and the technology to make it happen is available right now.
It’s called bidirectional charging, or V2X (Vehicle-to-Everything). Instead of only charging your car from the grid, a V2X system lets energy flow the other direction too — from your EV’s battery back into your home when the power goes out.
Think about how much energy is sitting in your car. Most home batteries store around 13.5 kWh. Many EV batteries hold 60–100+ kWh — enough to run an average home for two to four days.
The Solution: Sigenergy V2X DC Bidirectional Charger
We’re now installing the Sigenergy V2X DC Bidirectional Charger for homeowners across the Philadelphia region. It connects your EV to your home’s electrical system, switches automatically during an outage, and pairs beautifully with rooftop solar to create a truly self-sufficient energy setup.
Will My EV Work?
Not every electric vehicle supports bidirectional charging — compatibility depends on your specific make and model. Reach out to us and we’ll let you know exactly what’s possible with your car.
