The EcoFlow Stream Ultra X is a plug-in home battery designed specifically for outdoor use. With this compact, waterproof system, you can make direct use of solar energy on your balcony or terrace. Connect your panels, plug it into a wall socket, and the system automatically distributes the generated power between use, storage, and feed-in.
The Stream Ultra X delivers 2300 W of continuous power and features a battery capacity of 3.84 kWh. This allows you to easily power high-consumption devices such as washing machines, refrigerators, or power tools. The capacity can also be expanded up to 23 kWh, ensuring ample energy availability even on days with limited sunlight.
Through its four MPPT inputs, you can connect solar panels with a total power of up to 2000 W. Thanks to its Low-Light Cells, efficiency remains high even during cloudy weather or early morning hours. The high-quality LFP battery lasts up to 6000 charge cycles and retains about 70 % of its capacity after ten years, offering a lifespan of around 15 years.
The design of the Stream Ultra X is fully optimized for outdoor operation. Its IP65 rating provides protection against rain and dust, while the integrated self-heating function ensures reliable performance even at low temperatures.
Control is handled through the EcoFlow ecosystem with AI support. The system learns from your energy usage and automatically adjusts charging, discharging, and feed-in. The EcoFlow app provides real-time insight into your power generation, consumption, and savings. The Stream Ultra X is also compatible with smart protocols such as Tiber, Matter, and Shelly, allowing seamless integration with other smart devices.
