DELTA 3 Ultra Portable Power Station

Near-Unlimited Power. Zero Emissions. Zero Fuel.

The EcoFlow DELTA 3 Ultra is not a backup battery — it's a home energy system. With 4096Wh of EV-grade LiFePO4 capacity and 4000W of continuous output (8000W X-Boost), it can power entire home circuits, run central air conditioning, operate well pumps, and sustain a household through multi-day outages without a single drop of fuel or a breath of exhaust. This is the power station for homeowners who take preparedness seriously.

48-Minute Dual Charging

The DELTA 3 Ultra supports simultaneous AC + solar dual charging — combine a 1800W wall input with up to 2400W of solar panels and you can reach 80% charge in as little as 48 minutes. Under solar alone, six 400W panels (2400W) recharge it in approximately 2–3 hours of good sunlight. The 10ms UPS auto-switchover keeps computers, NAS drives, medical equipment and security systems running without interruption when the grid goes down.

What Can It Power?

4096Wh is 3–5 days of home essentials. The DELTA 3 Ultra can run central air conditioning for 3–4 hours, power a full-size refrigerator for 3+ days, operate a well pump through an extended outage, run all the lights, TV, router and device chargers in a medium home simultaneously, or power an entire construction job site for a full workday.

Expandable to 12kWh+

Add DELTA 3 Max Plus Extra Batteries to scale the system up to 12kWh+ for multi-day whole-home coverage. Pair with the EcoFlow Smart Home Panel 2 for automated per-circuit control — program exactly which circuits receive backup power during outages, in which priority order. EcoFlow's AI energy management via the OASIS 3.0 app optimizes charging and discharging automatically.
