Massive 18.4kWh whole-home backup with a free EcoFlow FlowMaster Generator Rectifier. You receive one DELTA Pro Ultra X inverter and three 6,144Wh Ultra-series batteries for 18,432Wh of storage. The included FlowMaster gives you another way to recharge during a long outage by connecting a compatible portable generator.
Sale price: $10,197 with free shipping in the contiguous United States.
Built for the Outages That Last Longer Than a Few Hours
This is not a small camping power station. It is a serious 120V/240V home-backup system with enough output for heavy household loads and enough battery capacity to keep essential circuits running much longer. The generator rectifier is what makes this package stand out: when solar conditions are poor, a compatible generator can help recharge the battery system without making gasoline your only source of power.

- Whole-home and hurricane backup
- Central air, well pumps and other 240V loads
- Extended outages with generator-assisted recharging
