DELTA Pro 3

Powerful Portable Energy for Home and Beyond
The EcoFlow DELTA Pro 3 is a high-capacity portable power station designed to provide dependable electrical power wherever it is needed. Combining a substantial 4,096Wh battery with up to 4,000W of AC output, it is capable of powering demanding household appliances as well as providing reliable energy for caravans, motorhomes, workshops, off-grid cabins and outdoor applications. Its X-Boost technology can increase supported output to 6,000W, giving the DELTA Pro 3 the capability to handle a wide range of high-power equipment.

Designed as more than simply an emergency battery, the DELTA Pro 3 can form part of a wider home energy system. Its expandable architecture allows storage capacity to increase from 4kWh to as much as 12kWh by connecting compatible Smart Extra Batteries, providing additional flexibility as energy requirements grow.

4,096Wh High-Capacity Battery
At the centre of the DELTA Pro 3 is a 4,096Wh lithium iron phosphate battery. The LFP chemistry is designed to provide a combination of high capacity, durability and long-term reliability, making the power station suitable for regular use as well as occasional emergency backup.

The battery is rated for up to 4,000 cycles before reaching 80% of its original capacity. This allows the DELTA Pro 3 to be used repeatedly over an extended period, whether it is charged from the mains, solar panels or another compatible power source.

Up to 4,000W of AC Output
The DELTA Pro 3 provides up to 4,000W of AC output through five outlets, giving it sufficient power for a broad range of appliances and electrical equipment. This makes it suitable for demanding devices that would be beyond the capabilities of smaller portable power stations.

EcoFlow's X-Boost technology can support compatible devices drawing up to 6,000W, providing additional flexibility when appliances require higher starting or operating power. The system is designed to provide power for equipment ranging from everyday household appliances through to more demanding equipment such as washing machines and EV chargers.

Expandable Energy Storage
The DELTA Pro 3 can be expanded as energy requirements increase. A single unit provides 4,096Wh of capacity, while compatible Smart Extra Batteries can increase the overall storage capacity to as much as 12kWh.

This expandable design makes the system suitable for a variety of applications. A single DELTA Pro 3 can provide portable power for shorter trips and essential home backup, while additional batteries can transform it into a much larger energy storage solution capable of supporting longer periods away from the mains.

Rapid Mains Charging
When connected to a suitable AC supply, the DELTA Pro 3 can accept up to 2,900W of charging power. EcoFlow states that the unit can charge from 0 to 80% in approximately one hour, significantly reducing the amount of time it needs to remain connected to the mains before it is ready for use again.

This rapid charging capability makes the DELTA Pro 3 particularly practical for situations where power needs to be restored quickly, while also allowing users to recharge between trips or outdoor activities without lengthy waiting periods.

Solar Charging Capability
The DELTA Pro 3 is designed to integrate directly with solar power systems, providing up to 2,600W of solar input. Its two solar charging inputs support different voltage ranges, with the high-voltage photovoltaic input accepting up to 1,600W and the low-voltage photovoltaic input supporting up to 1,000W.

EcoFlow states that solar charging can take the DELTA Pro 3 from 0 to 80% in approximately 1.5 hours under suitable conditions. This allows excess solar energy generated during the day to be stored and subsequently used when required, making the system suitable for more independent and renewable energy setups.

Multiple Charging Options
In addition to AC and solar charging, the DELTA Pro 3 supports vehicle-based charging. Its car charging inputs support both 12V and 48V charging configurations, providing additional flexibility when the power station is being used away from a conventional mains supply.

This combination of mains, solar and vehicle charging means the DELTA Pro 3 can be replenished in a wide variety of environments, whether it is being used at home, on a campsite or while travelling.

Whole-Home Backup Capability
The DELTA Pro 3 can be integrated into a home's electrical system using a compatible Manual Transfer Switch, allowing users to switch between grid electricity and stored battery power. This makes it possible to use the power station as part of a more comprehensive backup solution during power cuts.

EcoFlow specifies a 10ms switchover capability for its blackout backup functionality, helping keep essential equipment such as refrigerators, lighting and networking equipment operating when the mains supply is interrupted.

Installation of the Manual Transfer Switch requires a qualified electrician or certified professional, ensuring that the system is integrated safely into the home's electrical installation.

Quiet Operation
Despite its substantial power output, the DELTA Pro 3 has been engineered to operate quietly. EcoFlow specifies a noise level of just 30dB when operating at 2,000W, making it quieter than a typical running refrigerator.

This makes the power station more suitable for use in environments where excessive fan noise would be distracting, including living spaces, bedrooms, caravans and outdoor leisure areas.

Comprehensive Connectivity
The DELTA Pro 3 provides a wide range of outputs for connecting both mains-powered appliances and USB devices. Its five AC outlets provide up to 4,000W of output, while two USB-A ports provide up to 18W of fast charging.

Two USB-C ports support up to 100W each, making them suitable for charging compatible laptops, tablets, smartphones and other USB-C devices. A 12V DC output system provides up to 378W in total, incorporating a 12.6V/30A output, DC5521 connection and Anderson port.

This combination allows a wide variety of equipment to be powered simultaneously without relying on additional adapters or chargers.

Smart App Connectivity
Wi-Fi and Bluetooth connectivity allow the DELTA Pro 3 to be monitored and managed through compatible EcoFlow control functionality. The unit also supports CAN connectivity, providing integration possibilities for compatible energy systems and accessories.

Remote monitoring makes it possible to keep track of the power station's operating status and energy usage without needing to remain beside the unit, adding convenience for both home and mobile applications.

Designed for Portable Use
Although the DELTA Pro 3 is a substantial power station with a net weight of 51.5kg, its portable design is intended to make transportation and positioning as straightforward as possible. Its dimensions measure 693mm x 341mm x 410mm, providing a large energy capacity within a relatively compact footprint for a system of its output and storage capabilities.

The design makes it suitable for use in homes, recreational vehicles, off-grid cabins and other locations where access to reliable mains electricity may be limited or unavailable. Its plug-and-play approach also reduces the complexity associated with establishing a portable energy system.

Energy Storage for Everyday and Emergency Use
The DELTA Pro 3 is equally suited to planned and unexpected power requirements. At home, it can provide backup energy during outages, help store excess solar generation and potentially reduce reliance on grid electricity at certain times.

Away from home, the same combination of high capacity and high output makes it suitable for powering equipment in caravans, motorhomes, workshops and outdoor environments. Its ability to accept solar, AC and vehicle charging means it can remain useful even when conventional mains electricity is unavailable.

A Scalable Portable Power Solution
The EcoFlow DELTA Pro 3 combines high-capacity LFP energy storage, powerful AC output, rapid charging and extensive connectivity within a scalable portable power system. Its 4,096Wh capacity provides a substantial energy reserve, while 4,000W of continuous AC output and up to 6,000W through X-Boost allow it to support demanding equipment.

With support for up to two compatible Smart Extra Batteries, solar charging of up to 2,600W, rapid mains charging and whole-home backup integration, the DELTA Pro 3 can adapt to significantly different energy requirements. Its quiet operation, smart connectivity and multiple charging options further enhance its everyday practicality.

Whether providing emergency household backup, storing solar energy, powering a mobile lifestyle or supplying electricity in an off-grid environment, the EcoFlow DELTA Pro 3 offers a comprehensive and expandable approach to portable energy storage.
