EcoFlow DELTA Pro Ultra Inverter — 7.2kW AC Output, 0ms Online UPS, Scalable to 21.6kW
The DELTA Pro Ultra Inverter is the power core of EcoFlow's whole-home backup system, delivering 7200W of pure sine wave AC output across 120V and 240V simultaneously. This listing is for the inverter unit only — batteries are sold separately and must be purchased to enable energy storage and backup functionality.
⚠ Inverter Only — Battery Not Included. This listing does not include a DELTA Pro Ultra Battery. Energy storage and home backup functionality require at least one DPU Battery, sold separately. If you need a complete ready-to-use system, see the DELTA Pro Ultra Complete System listing.
⚠ Connection Cable Not Included. To connect a second inverter to Smart Home Panel 2, the Power Input/Output Cable must be purchased separately.
⚠ Smart Home Panel 2 Installation. Smart Home Panel 2 (sold separately) requires professional installation before use. Installation fees are assessed on-site and are separate from the product price.
⚠ Shipping Restriction. Cannot be shipped to Alaska, Hawaii, Puerto Rico, or other US outlying territories.
