Keep Your Home Powered Through Any Outage

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: The DELTA Pro Ultra delivers 7.2kWh (expandable to 25kWh) with 7,200W AC output — enough to hardwire into your home and run everything from HVAC to medical devices through an outage. For most homes, the DELTA Pro 3 (4.1kWh, expandable past 12kWh) covers essentials like fridges, lights, Wi-Fi, and CPAP machines for days.
• 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. A DELTA Pro Ultra or DELTA Pro 3 keeps your fridge, Wi-Fi, lights, and medical devices running for days — not hours. Pair it with a 400W bifacial panel and you're refilling from sunlight while the grid is still down. For whole-home integration, the DELTA Pro Ultra connects directly to your breaker panel via Smart Home Panel 2 for seamless, automatic backup the moment the power cuts.
