About this product

The EcoFlow DELTA 3 Ultra packs 3,072Wh of LiFePO4 storage and 3,600W of continuous 120V output into a wheeled, home-ready power station. With a sub-10 ms auto-switch, a TT-30 RV outlet and four ways to charge, it can back up a home office, satellite internet terminal and refrigerator during an outage, or power a cabin or RV far from the grid.

3,600W Output, 7,200W Surge

Run heavy appliances with 3,600W rated output, 7,200W surge and X-Boost up to 4,600W for compatible resistive loads. Four 20A outlets plus a 30A TT-30 port cover household and RV needs.

Four Ways to Charge

Wall: 0-80% in about 89 minutes (1,800W input)
Solar: up to 800W, 0-80% in about 3.37 hours
Generator: up to 1,600W input
Alternator: via the 800W Alternator Charger (sold separately)

10 ms Auto-Switch

When grid power drops, the DELTA 3 Ultra takes over in under 10 ms, keeping routers, NAS units, servers and communications equipment online.

Quiet and Durable

Runs at 25dB or less at 600W. Automotive-grade full-tab LFP cells, 24/7 BMS monitoring and a CTC structure are built for an estimated 10 years of use. Warranty is up to 5 years: 3 years standard plus a 2-year extension with app registration.

Home Connection and App Control

Connect to your home through a manual transfer switch or inlet box (sold separately). Wi-Fi and Bluetooth bring the unit into the EcoFlow app with OASIS 3.0, Storm Guard Mode and scheduled tasks. The DELTA 3 Ultra is not expandable; choose the DELTA 3 Ultra Plus if you need added capacity later.
