Get More from Your Solar
Already have solar panels? Fortress Power stores your excess solar energy so you can use it at night, during outages, or when electricity rates spike. Stop sending your energy back to the grid for pennies — keep it and use it on your terms.
Be Ready for the Next Outage
From wildfires and hurricanes to ice storms and aging grid infrastructure, power outages are on the rise. Fortress Power systems provide instant, automatic backup power that keeps your home running safely and quietly.
Live Off the Grid
If you want to live fully off-the-grid, Fortress Power systems give you freedom, flexibility, and control. With scalable battery storage, you can design a system that fits your energy goals — and grows with your home.
Qualify for Rebates and Incentives
Many homeowners can offset the cost of a battery system through local rebates, utility programs, and the 30% federal tax credit. We also participate in Virtual Power Plant (VPP) programs in select areas, offering ongoing cash payments for allowing your battery to support the grid during peak events.
Installed by Certified Experts. Backed by U.S.-Based Support.
Our nationwide network of Certified Installers makes it easy to get started. We’ll connect you with a qualified local professional who can design your system, install it safely, and help you claim any available incentives.

If you’re a hands-on homeowner, electrician, or contractor planning to install your own battery storage system, Fortress Power has your back. Our products are designed with DIY-friendly features, and we provide the resources and support you need to get it done right.

How Fortress Power Compares to Other Backup Solutions
Not all backup power is created equal. While traditional generators and older battery technologies offer some protection during outages, they come with limitations — from noise and maintenance to short lifespans and safety concerns. Fortress Power’s lithium iron phosphate (LFP) systems deliver clean, reliable, and long-lasting energy you can count on — with fewer compromises and more control.
