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 EcoFlow DELTA PRO, so you and your family will have uninterrupted power throughout your home during blackouts and natural disasters!
The DELTA PRO is the most powerful solar generator EcoFlow has ever released. This high quality, lithium based solar power station was designed to give you quick, easy portable power wherever and whenever you need it.
Not only does it contain an enormous 3,600 watt hour lithium battery, it is expandable, meaning it can seamlessly connect to multiple 3,600Wh expansion battery packs for a whopping total battery capacity of 25kWh (that's more than 3 x powerwalls)!
The EcoFlow DELTA PRO can store an incredible amount of power so that you can actually run your devices for long periods of time. It also offers some of the most advanced features of any power station on the market today.

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!
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.

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!

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!

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.
From tailgate power to extreme blackouts that last for days on end, EcoFlow DELTA Pro delivers up to 25kWh of capacity. With that, you're covered for any situation. That's the industry gold standard.
A single DELTA Pro unit offers an AC output up to 3600W, which can be expanded up to 4500W with X-Boost. This allows you to power window air conditioners, washing machines, and other devices.
If you’re looking for more power during an outage, you can connect two DELTA Pro units to the Smart Home Panel. This method gives you up to 7200W through your home circuits and provides power for 240V devices.
For US, preset wiring required to reach 240V
Or, for another option, connect two DELTA Pro units together with the Double Voltage Hub* to get 7200W, 240V to power heavy-duty devices. That’s enough power for your electric heaters, dryers, and other heavy-duty devices.
Only applicable for the US and Japan.
EcoFlow DELTA Pro is the world’s fastest charging portable power station. Multiple charging delivers record-breaking speeds at 6000W. To reach 6000W, you can opt for one of these multiple charging methods. Fully charge in 1.8 hours.
EcoFlow’s X-Stream charging technology isn't just fast, it's safe too. The battery management system ensures safety and longevity while you fully charge DELTA Pro from a standard AC wall outlet in 1.8 hours. Your EcoFlow DELTA Pro also has an adjustable AC charging speed from 200-3000W that gives you a flexible charging option.
