Built tough for indoor and outdoor use
The EcoFlow STREAM Ultra combines strong performance with a practical, compact design. Measuring 255 × 284 × 458 mm and weighing 23.1 kg, it offers an impressive balance of capacity and portability. Its IP65 protection rating means excellent resistance to dust and water, making it suitable for both indoor and outdoor environments. Added safety is ensured by DC II and AC III overvoltage categories, helping the system operate reliably even in more demanding conditions.

Long-lasting LFP battery for everyday reliability
At the heart of the system is a LiFePO₄ (LFP) battery with a 2 kWh rated capacity and 19.2 V nominal voltage. Designed for long-term use, it delivers over 6000 charge cycles, making it a dependable solution for years of operation. The fanless natural convection cooling system keeps the unit running quietly, which is especially useful in home environments where low noise matters.

Efficient solar charging with 4 MPPT channels
The STREAM Ultra supports four independent MPPT inputs (Maximum Power Point Tracking), allowing you to make better use of solar energy from multiple panel sections. Each MPPT supports up to 500 W, for a combined maximum PV input of 2000 W. With an MPPT voltage range of 15–60 V, maximum input voltage of 60 V, maximum input current of 14 A, and short-circuit current up to 20 A, the unit offers broad compatibility with many solar panel configurations.

Flexible AC output and greater energy independence
Designed for practical home energy use, the EcoFlow STREAM Ultra offers multiple operating modes for different needs. On the AC grid terminal, it supports 230 V / 50 Hz operation with a rated power of 800 W, rated current of 3.48 A, and maximum input power of 2300 W. For direct AC output, it delivers up to 1200 W continuous power with a rated output current of 5.22 A. In bypass mode, the maximum output current reaches 10 A, helping ensure stable performance under heavier loads. If you need more power, the parallel output mode supports up to 2300 W, giving you more flexibility for expanded setups.

Ready for demanding environments
Whether you plan to use it in a garage, workshop, garden setup, or off-grid hobby project, the STREAM Ultra is built to perform in a wide range of conditions. It operates at temperatures from -20°C to 55°C, supports 5%–95% relative humidity, and can be used at altitudes of up to 4000 m. It can also be safely stored within the same temperature range, making it a reliable option for year-round use.

Smart control via app, Wi-Fi, and Bluetooth
With Wi-Fi (WLAN) and Bluetooth connectivity, the EcoFlow STREAM Ultra makes day-to-day energy management simple and convenient. Using the EcoFlow app, you can monitor performance in real time, check energy data, and remotely optimize the system to match your usage and solar production.
