EcoFlow DELTA Pro Ultra Whole-Home Battery Backup | 7.2kW Inverter

Whole-home power security — for days, not hours. The EcoFlow DELTA Pro Ultra is a scalable home battery backup system built for households that refuse to compromise when the grid goes down.

• Massive scalable capacity (6–90kWh): Start with one unit and expand up to 90kWh — enough to power essential home appliances like lights and refrigerators for over 30 days of backup energy (usage times vary).
• High-output inverter (7.2kW–21.6kW): A single inverter delivers 7.2kW of continuous output — enough to run a 3-ton central air conditioner. Pair up to three inverters with the EcoFlow Smart Home Panel 2 to reach 21.6kW of total AC output across 120V and 240V circuits.
• Stable X-Fusion output: X-Fusion technology maintains a consistent 7,200W output regardless of load fluctuations, so your appliances run smoothly and reliably.
• Fast solar charging (5.6kW–16.8kW input): One inverter accepts up to 5.6kW of solar input using both High-PV and Low-PV technologies. Connect three inverters for up to 16.8kW — enough to replenish a full day's home energy in approximately 60 minutes of peak solar.
• Flexible solar compatibility: Works with portable solar panels or permanent rooftop solar systems. The plug-and-play design lets you build the setup that fits your home and energy goals.
• PV locking for safe, secure connections: A built-in PV locking feature ensures a solid, stable connection between your solar input and the inverter at all times.
• Space-efficient design: Stackable and compact enough to fit neatly in a garage or utility closet without taking over your living space.

Whether you're preparing for seasonal outages or working toward long-term energy independence, the EcoFlow DELTA Pro Ultra delivers the capacity, output, and flexibility to keep your household running on your terms.
