Product Description

Power your home, RV, off-grid cabin, or emergency backup setup with the incredibly powerful EcoFlow DELTA 3 Ultra + 400W Solar Panel bundle. Designed for users who need serious portable energy, this advanced solar generator combines a massive 3072Wh LiFePO4 battery with a high-efficiency 400W portable solar panel for reliable, renewable power anywhere.

With a powerful 3600W AC output and 7200W surge capacity, the DELTA 3 Ultra can handle nearly all essential appliances — from refrigerators and microwaves to power tools, medical devices, and RV systems. EcoFlow’s advanced X-Boost™ 3.0 technology even supports devices up to 4600W, making it one of the most versatile portable power solutions available today.

The included 400W foldable solar panel delivers efficient off-grid charging with up to 23% conversion efficiency using premium monocrystalline cells. Its lightweight, foldable design makes it ideal for camping, overlanding, RV living, outdoor events, and emergency preparedness.

Built with EV-grade LiFePO4 battery technology, the DELTA 3 Ultra is engineered for long-term durability with over 3,000 battery cycles and up to 10 years of daily use. The advanced battery management system continuously protects against overheating, overloads, and extreme temperatures for dependable performance in demanding environments.

One of the standout features is its ultra-fast UPS functionality with automatic switchover in under 10 milliseconds. During outages, critical devices like routers, computers, security systems, and medical equipment remain powered without interruption.

The DELTA 3 Ultra also supports multiple charging methods including AC wall charging, solar charging, car charging, generator input, and EV station charging, giving you unmatched flexibility wherever power is needed. Using EcoFlow’s X-Stream technology, the unit can recharge from 0–80% in as little as 48 minutes under optimal conditions.

Despite its massive output, the DELTA 3 Ultra operates quietly at just 25dB under low loads, making it ideal for indoor use, apartments, RVs, and overnight operation.
