The EcoFlow DELTA Pro Ultra is EcoFlow’s most powerful and advanced home backup solution yet—engineered for homeowners who need true whole-home resilience, grid independence, and long-duration emergency power. With an industry-leading 7.2–21.6 kW output and expandable 6–90 kWh capacity, it can power everything from essential circuits to your entire home, including central air conditioning, well pumps, electric dryers, induction cooktops, and more.

Offering unmatched reliability, DELTA Pro Ultra is the only portable power station certified to both UL1973 and UL9540, meeting the highest standards for residential energy storage. Whether you’re preparing for extended blackouts, integrating solar, or building a hybrid home-energy system, DELTA Pro Ultra delivers continuous, stable, and scalable power when it matters most.

Pair DELTA Pro Ultra with the EcoFlow Smart Home Panel 2 for fully automated backup—featuring <20 ms switchover, intelligent circuit prioritization, peak-shaving, and energy bill optimization. With up to 5 charging methods, including solar (up to 5600W), 240V AC, generators, and multi-source combinations, even your backup has a backup plan.

Built with ultra-durable LFP batteries, DELTA Pro Ultra delivers 3500+ cycles to 80% capacity, meaning over a decade of daily use. And thanks to built-in self-heating, the system continues to charge and operate normally even in freezing conditions.

From home backup to off-grid cabins, small businesses, RVs, and workshop power, DELTA Pro Ultra is the most versatile, future-ready whole-home power solution EcoFlow has ever built.
