What it is

The EcoFlow DELTA Pro stands as a bridge between portable power and permanent home backup. With a massive 3600Wh base capacity and a robust 3600W AC output, it can comfortably run heavy-duty appliances like refrigerators, well pumps, and even electric vehicle charging. Its lithium iron phosphate battery chemistry ensures a long service life, while the unique ability to charge at EV stations makes it one of the most versatile energy hubs for modern off-grid lifestyles. What sets this unit apart is the sophisticated ecosystem for expansion. Users can scale the system up to a staggering 25kWh using extra batteries and smart generators, effectively creating a whole-home energy solution without the fumes of traditional gas generators. The X-Stream technology allows for incredibly fast wall charging, reaching a full battery in under two hours, which is vital when preparing for incoming storms or short power outages.

Ravvy AI insight

While the 99-pound weight limits true portability, the DELTA Pro excels as a semi-permanent installation for disaster readiness. We recommend pairing it with at least 400W of solar panels to maximize its 2.8-hour solar recharge potential and ensure true energy independence during prolonged grid failures.
