EcoFlow STREAM Ultra X

EcoFlow STREAM Ultra X – Intelligent energy storage for maximum independence

With the EcoFlow STREAM Ultra X, you can take your balcony power system to a new level. This powerful, AC-coupled power storage system combines high capacity, flexible expandability, and intelligent control – for a sustainable and reliable energy supply right in your home.

Maximum solar yield of 2000 W via four MPPT inputs

The STREAM Ultra X is equipped with four independently operating MPPT inputs of 500 W each. This allows you to utilize the full potential of your photovoltaic system – even in partial shade or changing light conditions.

3.84 kWh storage capacity for continuous supply

The long-lasting 3840 Wh LFP battery provides reliable power even in the evenings or during power outages. Ideal for households with higher consumption or for covering periods of low sunlight for several days.

Easy integration into existing systems

Thanks to AC coupling, the STREAM Ultra X can be integrated into your existing balcony power system without any structural modifications. It's easy to set up via a wall outlet – plug & play.

Modular expandable – individually adaptable

Flexibly expand your setup with up to six additional STREAM or AC storage units. The integrated energy management system automatically coordinates all units for maximum efficiency and scalability.

Electricity for heavy consumers

In combination with the EcoFlow AC Pro, you can easily operate even high-performance devices with up to 2300 W – from washing machines to power tools.

Intelligent control with EcoFlow OASIS

Keep track of your energy usage and optimize your self-consumption with the EcoFlow OASIS app. Features like TOU mode enable charging at cost-effective times, while smart meter integration allows for precise, real-time consumption control.

Compatible with common smart meters

For precise consumption analysis, the STREAM Ultra X can be connected to the EcoFlow Smart Meter or the Shelly 3EM. This allows you to sustainably reduce your energy costs and increase the transparency of your electricity consumption.

The EcoFlow STREAM Ultra X is more than just a solar storage system – it is the central element for an independent, scalable and future-proof energy supply in the private sector.
