The EcoFlow STREAM Ultra X is a high-capacity home battery storage system designed to store solar energy and grid electricity for maximum performance and scalability. Ideal for larger households or growing energy demands, this powerful yet flexible plug-and-play energy storage system captures and stores excess solar power for use day and night, helping reduce electricity bills and reliance on the grid.
With up to 2300W of output, it can power a wide range of household appliances, making it well suited for flats, homes, and balcony solar systems. Its higher capacity and performance make it particularly suitable for properties with greater energy demands.
Designed to grow with your needs, the system supports expansion by connecting additional STREAM Series units in parallel or adding compatible STREAM Extra Batteries. This allows you to increase storage capacity and support higher energy usage over time.
Using the EcoFlow app, you can monitor real-time energy usage, track solar generation, and check battery levels from your smartphone. You can also customise charging and discharging schedules to maximise savings by using stored energy during peak tariff periods.
