The Premium Home Backup System with 3600W Output

The EcoFlow DELTA 3 Ultra Plus sits at the pinnacle of EcoFlow's DELTA 3 lineup — delivering 3072Wh of EV-grade LFP capacity and 3600W of continuous output (7200W surge) in a system reviewers describe as able to "power heavy appliances like a mains feed." Its Smart Output Priority feature lets you independently manage different circuit groups from the EcoFlow OASIS 3.0 app. With 48-minute dual charging and 10ms UPS auto-switching, it's purpose-built for seamless, automatic home backup.

Smart Output Priority — A Game Changer

Unlike conventional power stations that treat every outlet identically, the DELTA 3 Ultra Plus lets you control different AC output groups independently. Assign your refrigerator and medical devices to Priority 1, entertainment and lighting to Priority 2, and configure automatic load shedding when battery reserves drop below your set threshold. This is energy management, not just battery backup.

Scales to 11kWh

Connect multiple compatible DELTA 3 series batteries to scale the system up to 11kWh — enough for 3–5 days of whole-home essential coverage. EV-grade LFP cells deliver 3,000+ cycles rated for 10+ years, making this a long-term investment in home resilience rather than a disposable product.

  • 3072Wh EV-grade LFP — expandable to 11kWh with compatible DELTA 3 batteries
  • 3600W continuous / 7200W surge — powers whole-home essential circuits simultaneously
  • Smart Output Priority: independently manage circuit groups via app or touchscreen
  • 48-min dual charging: AC + up to 1600W solar simultaneously
  • 10ms UPS auto-transfer — seamless transition for computers & sensitive devices
  • X-Boost 3.0 extends effective device support up to ~4500W for high-draw loads
  • LFP: 3,000+ cycles, 10+ years — EV-grade reliability for home backup
  • OASIS 3.0 app: AI energy management, scheduling, remote control & monitoring
✦ Perfect for:

Whole-home backup, serious off-grid living, high-demand RV systems & homeowners wanting premium smart energy management.
