When the grid goes down, the costs add up fast — spoiled food, lost work, dead phones, and a house that goes dark for days. A home backup power station turns an outage from a crisis into an inconvenience.

• Flagship whole-home power:Choose DELTA Pro Ultra or DELTA Pro Ultra X for whole-home backup and high-demand appliances. For a lower-cost, proven setup, DELTA Pro can cover essential loads such as refrigerators, lights, Wi-Fi, and CPAP machines and supports expandable storage.
• Fastest recharge:0–80% from a wall outlet in about 50 minutes; refill from solar while the sun is out. The DELTA Pro Ultra supports up to 3,000W solar input — recharge faster than any other home battery.
• Built to last:Long-life LFP (LiFePO4) batteries keep 80% capacity after 3,500+ cycles — roughly 10 years of weekly use. All units come with a 5-year warranty through Livvolt.

Real homes, real outages. DELTA Pro Ultra, DELTA Pro Ultra X, and DELTA Pro can keep refrigerators, Wi-Fi, lights, and medical devices running when the grid is down. Pair the right system with solar to refill from sunlight. For whole-home integration, DELTA Pro Ultra works with Smart Home Panel 2 for seamless automatic backup.
