EcoFlow DELTA Pro 3 – Powerful Power Station for Mobile and Stationary Applications
The EcoFlow DELTA Pro 3 is the consistent further development of the DELTA series and is designed for users with high energy requirements. With a 4,096 Wh capacity, 4,000 W continuous output, and an expandable battery system, it is suitable for both mobile applications and as a powerful household backup power solution.
Thanks to the integrated trolley design with wheels and pull handle, the power station remains mobile despite its weight – ideal for camping, motorhomes, construction sites, or temporary power supply.
High Performance and Fast Switching Time
The DELTA Pro 3 provides pure sine wave power and reliably supplies even high-performance devices such as air conditioners, pumps, or power tools.
The integrated UPS function with a switching time of <10 ms protects sensitive electronics during power outages.
Flexible Charging Options and Solar Integration
The power station supports AC charging, dual PV solar charging, and EV charging. Via two solar inputs, up to 2,600 W of solar input power is possible. In combination with EcoFlow PowerStream, the DELTA Pro 3 can also be integrated into a DIY solar home energy system.
Expandable, Quiet, and Safe
With up to two Smart Extra Batteries, the total capacity can be expanded to 8 kWh or 12 kWh.
The LiFePOâ‚„ battery provides high cycle stability, while the X-Cooling system enables quiet operation. An integrated safety and battery management system monitors all relevant system parameters in real time.
Central Control via App
Using the EcoFlow App (WiFi & Bluetooth), charging status, energy consumption, and power sources can be conveniently monitored and controlled – both during mobile use and stationary operation.
