EVs + Home Backup Batteries: Power and Peace of Mind for Every Household

For many families, rooftop solar isn’t yet an option — whether because of cost, renting, shaded roofs, or HOA restrictions. But that doesn’t mean you can’t enjoy the resilience and cost-saving benefits of clean energy at home. Pairing an electric vehicle (EV) with a home backup battery gives you the ability to store energy, lower your bills, and keep the lights on — with or without solar panels.

Energy Security Without Solar

Even if you don’t generate your own power, a home backup battery can charge from the grid when electricity is cheapest (overnight or during off-peak hours). That stored energy can then be used during the day when rates are higher or in the event of a power outage. Pair it with an EV, and you have a ready supply of electricity that keeps your household essentials running.

 

Even Better With Solar

For those who do have rooftop solar, adding a battery and an EV makes the system far more powerful. Instead of sending excess solar energy back to the grid at low rates, you can store it for nighttime use or to charge your car directly. That means more of your clean energy is used by you — reducing bills, increasing self-sufficiency, and maximizing your solar investment.

 

Lower Bills, More Control

  • With no solar: Charge your battery and EV during off-peak hours when electricity is cheapest, then use that stored energy later.

  • With solar: Store your free solar energy during the day and use it at night to avoid buying expensive grid electricity.

Either way, you gain control over energy costs and protection against rising utility rates.

 

Cleaner, More Resilient Living

EVs paired with batteries reduce reliance on fossil fuels while making households more resilient against power outages, natural disasters, or grid stress events. And remember — when the power goes out, gas pumps can’t pump gas. But with an EV and home backup battery, you can keep your car and your home powered, no matter what.

 

Bottom Line

Whether or not you can install rooftop solar today, pairing an EV with a home backup battery gives you a clean, affordable, and resilient energy solution. And if you add solar later, that system becomes even stronger — helping you save money, stay powered, and drive on clean energy for years to come.
