Power Your Home Without Compromise.

Most residential installations are completed in a single day — typically 4 to 8 hours depending on your home's electrical panel configuration and whether you're adding solar at the same time. Our certified installation partners will conduct a pre-installation assessment to confirm your home is ready and provide a precise timeline.

No. HomeVault™ works as a standalone battery system and can charge directly from the grid. However, pairing it with solar panels dramatically increases your savings by storing free solar energy for use at night or during peak pricing hours. The HomeVault™ 3 includes a fully integrated solar inverter, making the solar + storage combination especially seamless.

HomeVault™ 2 is designed to work with virtually any existing solar inverter brand. HomeVault™ 3 and HomeVault™ Plus include their own integrated inverters and are optimized for new solar installations. Our installation partners will assess your current system during the pre-installation visit and recommend the best configuration.

Yes. HomeVault™ is designed for whole-home backup. A single HomeVault™ 3 unit delivers 11.5 kW of continuous backup power — enough to run your HVAC, refrigerator, lights, EV charger, and other major appliances simultaneously. For larger homes or extended outages, multiple units can be stacked to increase both capacity and power output.

The U.S. federal Residential Clean Energy Credit (ITC) provides a 30% tax credit on the full cost of a qualifying home battery + solar system. Many states and utilities offer additional rebates, net metering programs, and demand response incentives. Our team will help you identify all available incentives in your area as part of your free energy assessment.

Payback periods vary based on your electricity rates, solar system size, and local incentives — but most homeowners see full payback in 6 to 9 years. After payback, the system continues generating savings for the remaining life of the warranty and beyond. Homes in high-rate states like California, Hawaii, and New York typically see the fastest returns.

The HomeVault™ limited warranty covers defects in materials and workmanship for 10 years from the installation date. It also guarantees a minimum energy retention of 70% of original capacity over the warranty period. Warranty service is handled by our certified partner network, with most claims resolved within 5 business days.

HomeVault™ systems are engineered to last well beyond the 10-year warranty period — most units are expected to retain over 80% capacity at year 10 and continue operating for 15+ years with normal use. After the warranty period, extended service plans and battery module replacement options will be available through our partner network.
