Tons of Power When You Need it the Most

While the EcoFlow DELTA PRO’s built-in 3,600Wh battery is impressive, it is the ability to expand the capacity up to 25kWh that really makes this unit turn heads!

Compatibility with the EcoFlow Smart Home Panel also means you can wire your home circuit panel directly to the DETLA PRO, so you and your family will have uninterrupted power throughout your home during blackouts and natural disasters!

Industry-Leading Charge Capabilities

The DELTA PRO can be charged 6 different ways, including directly through an electric vehicle (EV) charge station! Even more impressive is the fact that it is MultiCharge and X-Stream enabled, which means you can achieve a rapid 6,000W charge rate by charging with AC power and solar power simultaneously!

In other words, you can plug the PRO into a wall outlet and solar panels at the same time to fully charge the internal battery in just 1.8 hours!

Lasting Power

The EcoFlow DELTA PRO’s state-of-the-art LFP battery is rated to 6,500 complete cycles. This means it will last for years on end before losing a significant amount of its original storage capacity!

The integrated battery management system provides real-time status updates and regulates the voltage, current, and internal temperature, so the PRO always operates safely and efficiently.

User-Friendly Design and Remarkable Output Versatility


While all of EcoFlow's generators are known for offering a versatile range of output ports, the DELTA PRO takes things even further. Users can plug their electronic devices and appliances directly into any of the PRO’s 12 ports:


# of Plug(s) Type of Plug(s)
 2 USB-A Fast-Charge Output Ports
2 USB-A Standard Output Ports
2 USB-C 100W Output Ports
4 Wall-Style 20A AC Output Sockets
1 30A Anderson AC RV Port
1 Car-Style 12V Charging Port


The EcoFlow Delta PRO is also Wi-Fi enabled and easily connects with EcoFlow’s user-friendly mobile app. This means you can monitor and adjust the PRO using your smartphone or tablet!

Rugged Portability


While you would expect such a powerful battery backup system to be extremely bulky and cumbersome, the EcoFlow DELTA PRO features built-in wheels and an extendable suitcase-style handle.

This means it is also ideal for RV trips and just about any off-grid outdoor adventure! The PRO allows you to take backup power and solar capabilities wherever your next adventure takes you!

What Can the EcoFlow DELTA PRO Power?

The DELTA PRO’s powerful inverter and efficient MPPT charge controller give it the ability to offer 3,600W of AC power, which can be expanded to 4,500W with the unit’s all-new X-Boost capabilities.

This means you can power just about any electronic device or appliance without running into short-circuits and power failures. For even more power, you can pair two DELTA PROs to achieve 7,200W of power!

The EcoFlow DELTA PRO’s outstanding power inverter and high-capacity battery can be used to supply power in the following ways:

Appliance Run Time
CPAP Machine 40W (AC) 50 hours
Refrigerator 120W (AC) 24 hours
Light 10W (DC) 337 hours
50” TV 110W (AC) 27 hours
Laptop 60Wh 57 times
Phone 11Wh 313 times


Whether you are looking for a backup power supply for emergency situations and prolonged blackouts, or you need portable power for your RV or off-grid cabin, the EcoFlow DELTA PRO has everything you need!


This is the first solar generator to include a remote monitor and control screen! Designed specifically for the EcoFlow DELTA Pro. Ideal for storing your DELTA Pro in a cabinet, the garage, or your basement, you can easily connect to it over Bluetooth or an ethernet cable and get a second display screen right where you need it most. 

Easily monitor your system: The display shows how much energy you’re using, the remaining battery time, and everything else DELTA Pro’s screen shows. It’s also a convenient place to turn on/off the AC outlets, DC outlets, or entire unit.

Two simple ways to connect: Move the screen around when connected with Bluetooth; set it and forget it with a wired connection that works over longer distances.

Control at a distance: Once you have it all set up, you can monitor & control your portable power station from afar. Ideal when your DELTA Pro is set up with solar panels, or at a charger.

Note: This accessory is only compatible with the EcoFlow DELTA Pro.
