EcoFlow STREAM Ultra X – Intelligent Energy Storage for Maximum Independence
With the EcoFlow STREAM Ultra X, you take your balcony power plant to a new level. This powerful, AC-coupled energy storage system combines high capacity, flexible expandability, and intelligent control – for a sustainable and reliable energy supply right in your home.
Maximum Solar Yield with 2000 W via Four MPPT Inputs
The STREAM Ultra X is equipped with four independently operating 500 W MPPT inputs. This allows you to utilize the full potential of your photovoltaic system – even with partial shading or changing light conditions.
3.84 kWh Storage Capacity for Continuous Supply
The durable LFP battery with 3840 Wh provides reliable energy even in the evening hours or during power outages. Ideal for households with higher consumption or to cover multi-day periods with low sun exposure.
Easy Integration into Existing Systems
Thanks to AC coupling, the STREAM Ultra X can be integrated into your existing balcony power plant without structural modifications. Commissioning is straightforward via the power outlet – Plug & Play.
Modularly Expandable – Individually Adaptable
Flexibly complement 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.
Power for High-Consumption Appliances
In conjunction with the EcoFlow AC Pro, you can easily operate powerful 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 self-consumption with the EcoFlow OASIS app. Features like the TOU mode allow charging during cost-effective times, while smart meter integration enables precise consumption control in real time.
Compatible with Common Smart Meters
For accurate 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 private households.
