Fortress Power energy storage systems give homeowners and businesses the freedom to take control of their power. From short-term outages to long-term energy independence, our batteries are built for safety, longevity, and seamless integration with solar, generators, and smart inverters.
Explore how our systems are used in a wide range of residential and commercial applications below.
Virtual Power Plant (VPP) Participation
Join a growing network of smart homes that support the grid — and get rewarded for it. Fortress Power systems are approved for select utility VPP programs, allowing your battery to provide energy back to the grid during peak demand. Homeowners can earn various upfront and performance incentives while helping improve grid stability and accelerate the shift to clean energy.
Backup Power for Grid Outages
Keep critical appliances running during storms, blackouts, and utility failures. Fortress Power systems deliver reliable backup for lights, refrigerators, sump pumps, medical devices, and more.
Off-Grid Living
Live independently with scalable energy storage that works seamlessly with solar and generator power. Perfect for remote cabins, homesteads, or homes without reliable grid access.
Time-of-Use & Bill Management
Reduce electricity costs by storing energy during off-peak hours and using it when rates are highest. Ideal for homeowners in areas with time-of-use pricing or high demand charges.
Solar Self-Consumption (Zero Grid Export)
Maximize the value of your solar panels by storing excess energy during the day and using it at night — increasing your energy independence and reducing grid reliance.
Reduce Peak Demand Charges
For businesses and large residential properties, energy storage can significantly lower electricity costs by reducing peak demand charges. Fortress Power systems store energy when usage is low and discharge it when consumption spikes — helping manage load profiles, avoid costly demand fees, and improve energy efficiency.
