One powers all
A single inverter delivers 7200W at 120V and 240V, even while charging. Triple the inverters for 21.6kW of AC output.
Scalable energy security
Each battery holds 6144Wh, and the system scales up to 15 batteries for 90kWh. That covers over 30 days of essential power for a standard North American household.
Customize your home power
Prioritize specific circuits in the EcoFlow app to extend backup time. The system can analyze usage to offset peak rates and use solar to lower energy bills.
Fast, quiet and uninterrupted
A 6144Wh battery recharges fully in 2 hours from EV chargers, solar, wall outlets or generators. Fans stay off for the first half hour at 2000W output for silent operation.
