EcoFlow DELTA Pro 3

EcoFlow DELTA Pro 3

Powerful and quiet battery station

It is ready to reliably power almost all of your basic home appliances and will be conveniently accessible for your entire family. Its operation is simple. You just plug in the cable, press the button and the power flows. In addition, it works very quietly, so it will not disturb even your sleep in the same room. Compared to DELTA Pro, it brings higher capacity (4,096 Wh), higher operating power (4,000 W) and higher peak power (6,000 W).

It is characterized by high quality and durability. Featuring a LiFePO4 battery, it has a variety of outputs, including standard AC power outlets, USB-A, USB-C, 12V DC5521 and Anderson ports to support a variety of appliances and devices. Multiple charging options make it easy to switch between different methods based on current needs.

Maximizing performance

Thanks to advanced X-Fusion technology, all AC output sockets of the station always provide optimal performance even in bypass mode. This mode turns on automatically when the station is charging and at the same time it is being used for power. It can provide power up to its maximum rated power, regardless of the amount of current input.

Powering appliances with high power consumption

X-Boost is an innovative technology that is used exclusively in EcoFlow battery stations. It allows you to drive appliances with a higher power consumption than the nominal power of the station, in the case of DELTA Pro 3 devices up to a power consumption of 6,000 W.

Recharge options

Within range of the network, it is possible to charge the station with a mains socket or from a charger for electric cars. Outside the reach of the mains, the DELTA Pro 3 can be recharged with solar panels, a smart generator, a car socket or a DC-DC charger. The station offers a service life of up to 4,000 cycles until the capacity drops to 80% of its original value.

Solar charging

To recharge the DELTA Pro 3, it is possible to use EcoFlow solar panels by connecting to a low-voltage or high-voltage solar input. Overvoltage protection allows the station to handle voltages up to 150 V in the case of the high-voltage port, and up to 60 V in the case of the low-voltage port.

Home backup power supply

You can use this battery station for a backup power system in case of power outages. In the event of an outage, the station with a switching time of 10 ms will automatically power the connected basic household appliances, so you will not even notice a supply interruption. Expandable battery capacity and different types of sockets make DELTA Pro 3 a very suitable and reliable backup power source.

Expandable capacity

If you are often in a situation where you need a lot of electricity outside the range of the network, or you have to replace longer power outages, you can expand the capacity of the station in advance with additional batteries. DELTA Pro 3 supports the connection of up to 2 additional batteries, so the total capacity of the station after connecting them can be up to 12,288 Wh.

Control by phone

Using the EcoFlow mobile application, you can control the operation of the station and the power supply of all connected devices via your phone, from any location. The station supports both Wi-Fi and Bluetooth connections and can thus adapt to current conditions. At the same time, you can conveniently monitor energy consumption details and software updates in real time in the application.

Helper for work and fun

The station not only provides electricity for the home and for travel, but is also a safe source of energy for any type of work or hobby. Whether you work at home or outdoors, DIY or professional, DELTA Pro 3 can always provide you with enough power.
