Description

The EcoFlow DELTA Pro Ultra power station offers the highest capacity and output power among current EcoFlow battery energy storage systems (BESS).

With a powerful 12kWh AC output, the DELTA Pro Ultra with two batteries can run multiple devices simultaneously, including refrigerators, microwaves, TVs, lights, air conditioners (up to 5,000 BTU), and more. Whether you’re operating high-drain tools or powering an entire room, it delivers dependable energy when you need it most.

This flexible design allows you to keep your home running smoothly for days during outages or maintain a comfortable off-grid setup for extended periods.

Grow as you go

This model includes one inverter unit and two 6kWh base batteries. Additional DELTA Pro Ultra Extra Batteries add 6kWh each – connect up to five for a total of 30kWh of usable energy. This flexible design allows you to keep your home running smoothly for days during outages or maintain a comfortable off-grid setup for extended periods.

Long-lasting technology

Powered by Lithium Iron Phosphate (LiFePO₄) battery chemistry, the DELTA Pro Ultra offers enhanced safety and durability. These cells are rated for over 3,500 full charge cycles while maintaining over 80% of their original capacity, ensuring a service life of more than ten years – even with daily use.

Power for every situation

For work: Suitable for remote work and backup scenarios, the DELTA Pro Ultra can power desktop computers, lighting, printers, freezers, and essential tools. It delivers reliable energy wherever it’s needed – whether off-grid or during grid interruptions.

For home: The DELTA Pro Ultra operates as a standalone unit or integrates with a full-home backup system. It supports various charging methods, including solar panels, generators, and EV chargers. Its built-in UPS technology provides uninterrupted power during outages and protects sensitive electronics. For loads under 2000W, the system runs silently at 0 dB – ideal for night-time operation without disruption.

For out and about: Though powerful enough for whole-home backup, the DELTA Pro Ultra’s modular design makes it highly portable. Users can take only the components needed, and the optional DELTA Pro Ultra Trolley offers added convenience for transport.
