Power interruptions are no longer an inconvenience — they are a variable you can control. Our large batteries for home backup are engineered to deliver dependable backup power for home use, ensuring that critical appliances, lighting systems, HVAC components, and sensitive electronics remain operational when the grid fails. Designed with the realities of American households in mind, these whole house batteries unify resilience, efficiency, and advanced safety into a single, future-ready energy solution.
At the core of each system lies a long-lasting lithium battery built on industrial-grade LiFePO4 lithium battery chemistry. This technology is chosen not for trend value, but for performance — exceptional thermal stability, high cycle life, and predictable output over years of daily use. An intelligent BMS, multi-layer overcharge protection, and robust cell architecture work together to provide consistent, safe energy storage you can rely on. With capacities starting at 10 kWh and above, these units are purpose-built for true whole house backup, from essential circuits to full-home energy continuity.
Energy independence should not require compromise. Many of our house backup batteries are fully off-grid ready, enabling seamless integration with solar panels and hybrid photovoltaic systems. Whether you are planning a standalone off-grid installation or enhancing grid-tied resilience, the modular design allows you to scale storage capacity as household demand grows — without system replacement, without friction.
