EcoFlow DELTA Pro Ultra
The Ultimate Movable Home Battery Solution
When the power goes out, most families scramble to keep the lights on, food cold, and devices charged. Traditional solar battery systems are expensive, complicated, and often fixed in place. But what if there was a smarter, more affordable way to secure whole-home backup power?
Meet the EcoFlow DELTA Pro Ultra — the most advanced, flexible, and cost-effective home battery solution on the market today.
Why DELTA Pro Ultra is a Game-Changer
Unlike traditional solar + battery setups, which can cost tens of thousands upfront, the DELTA Pro Ultra comes in at around 75% lower upfront cost, with a payback period of just 2.5 years¹. That means more families can enjoy reliable power without waiting a decade to see a return on investment.
And because it’s movable, you’re not locked into a fixed system — you can adapt your setup to your lifestyle, whether that’s whole-home backup, RV living, or off-grid adventures.
Key Features of the DELTA Pro Ultra
- Massive Output Power
Each unit delivers 7.2kW of output, enough to run heavy loads like a 4-ton air conditioner. Need more? You can scale up to 21.6kW, rivaling traditional solar battery systems. - Expandable Storage
Start small with 6kWh and expand up to 90kWh. That’s enough energy to power your entire home for days at a time. - Seamless Backup with 20ms Auto-Switchover
With the EcoFlow Smart Home Panel 2, the DELTA Pro Ultra automatically kicks in during an outage — so fast you won’t even notice the lights flicker. It also allows 12 customizable circuits for smarter energy management. - Unmatched Solar Input
The system supports 5.6kW–16.8kW of solar input. Just one hour of sunlight can provide a full day of power, making it a serious option for sustainable living. - Generator Compatibility
Pair with a 3–12kW portable gas generator for extended outages — ensuring you’re never without power, even during long storm seasons. - EV Charging Capabilities
With the PowerPulse EV Charger (9.6kW), you can turn solar into mileage, adding up to 35 miles of driving range per hour of charge.
Ultra-Smart, Ultra-Flexible, Ultra-Reliable
The DELTA Pro Ultra + Smart Home Panel 2 form an intelligent whole-house energy ecosystem. Together, they offer:
- Uninterrupted Power — lightning-fast auto switchover keeps your home running smoothly.
- Unlimited Scalability — whether you need a little or a lot, the system grows with your household.
- Ultra-Smart Controls — manage circuits, monitor performance, and optimize energy usage right from the EcoFlow app.
Who Is It For?
- Homeowners in outage-prone areas (hurricanes, wildfires, or grid instability).
- Families who want a clean, quiet alternative to noisy gas generators.
- Solar users who want energy independence without sky-high installation costs.
- EV owners looking for a dual solution: home backup + vehicle charging.
