Description
Never run out of backup power again — the EcoFlow DELTA Pro 3 + Smart Generator 4000 (Dual Fuel) bundle creates a self-managing, unlimited-runtime backup power system that automatically keeps itself charged without any manual oversight. The DELTA Pro 3 handles your home’s energy demands while the Smart Generator 4000 monitors battery levels and fires up automatically when a recharge is needed — then shuts off again when charging is complete. The result is true set-and-forget home backup power that can last indefinitely.
The DELTA Pro 3 is EcoFlow’s flagship portable power station — delivering 4,000W of AC output with native 120V and 240V capability, 4kWh of expandable LFP storage (up to 48kWh), and UL9540 certification. The bundled Smart Generator 4000 runs on either gasoline or LPG (dual fuel) and produces 4,000W of output, fully compatible with the DELTA Pro 3’s smart charging system. Users set a battery threshold in the EcoFlow app — when the DELTA Pro 3’s state of charge drops below that level during an outage, the Smart Generator automatically starts. Once the battery reaches the target level, it shuts off. This intelligent cycling burns fuel only when needed, extending fuel runtime dramatically compared to a generator running continuously.
Together, this bundle handles multi-day power outages, natural disasters, and extended off-grid living scenarios where solar alone isn’t reliable enough. The DELTA Pro 3 also accepts up to 2,600W of solar input for renewable charging when sunlight is available, further reducing generator runtime. Storm Guard auto pre-charging and full EcoFlow app integration round out the package.
Backed by a free 5-year warranty on the DELTA Pro 3.
