EcoFlow DELTA Pro Ultra

The most powerful whole-home backup solution.

Month-long power security.

6-90kWh Capacity

Take home power dependability to another level with up to 90kWh battery capacity. For a standard household, that's over 30 days of essential backup power to keep appliances like lights and refrigerators running strong (time may vary). Stackable and space-saving, it packs comfortably into a garage or utility closet.


One unit covers every appliance.

7.2kW-21.6kW, 120V & 240V Output

With a 7.2kW output, EcoFlow DELTA Pro Ultra effortlessly runs even energy-hungry household items, like a 3-ton central air conditioner*. For more power, pair 3 inverters with the EcoFlow Smart Home Panel 2 to unlock a 21.6kW AC output. Plus, with X-Fusion you'll get a constant 7200W output no matter what.*

Powers through the most challenging situations.

EcoFlow DELTA Pro Ultra tackles even the most grueling conditions. Whether it's extreme weather or freezing winters, this giant safeguards your power security, just like usual.
