The EcoFlow STREAM Ultra is a high-capacity home battery storage system designed to store solar energy and grid electricity for reliable everyday use. Ideal for residential energy management, it helps reduce electricity bills, increase energy independence, and provide backup power during outages. A plug-and-play home energy solution, it captures, stores, and delivers power from both solar panels and the grid. Designed for seamless integration into your home, it helps optimise energy usage throughout the day while reducing reliance on grid electricity.
Delivering up to ~2,300W of AC output, the STREAM Ultra can power a wide range of household appliances and essential circuits. Unlike portable power stations, it integrates into your home energy setup to support daily usage and improve overall energy efficiency.
The system supports multiple charging options, including mains power and solar input via multiple MPPT channels, allowing you to maximise solar generation and store excess energy for use when you need it most.
With the EcoFlow app, you can monitor solar generation, battery levels, and home energy usage in real time, as well as adjust settings such as charge schedules and operating modes. Built-in Wi-Fi enables remote control, while Bluetooth provides reliable local access when internet connectivity is unavailable.
