EcoFlow STREAM Ultra: 2-in-1 intelligent energy storage system with microinverter

EcoFlow STREAM Ultra 2-in-1 Smart Energy Storage System with Microinverter

The EcoFlow STREAM Ultra is an advanced energy storage system integrated with an inverter, designed to maximize the potential of your photovoltaic installation. This device combines robust battery capacity (2 kWh), high efficiency and intelligent energy management to ensure home energy independence. Thanks to its quiet operation, wide operating temperature range and IP65 protection class, it is ideal for both indoor and outdoor use.

Robust and High Strength Design

With dimensions of 255 × 284 × 458 mm and a weight of 23.1 kg, the STREAM Ultra offers excellent mobility despite its powerful features. The IP65 rated enclosure ensures complete resistance to dust and water, allowing safe use both indoors and outdoors. The DC II and AC III overvoltage category ensures safe operation even in difficult conditions.

Long Battery Life

The EcoFlow Stream Ultra uses a 2 kWh lithium-iron-phosphate (LFP - LiFePO₄) battery with a nominal voltage of 19.2 V. Designed to last a long time, it offers more than 6,000 life cycles, ensuring years of reliable use. Natural fanless cooling ensures quiet and trouble-free operation.

Efficient Charging System with 4 MPPT

Stream Ultra supports four independent MPPT (Maximum Power Point Tracking) inputs to optimize energy use from photovoltaic panels. Each channel manages up to 500 watts, for a maximum total input power of 2,000 watts (60V/14A). The MPPT voltage range is 15-60V, with a maximum short-circuit current of 20A, ensuring compatibility with a wide range of solar panels.

Energy Independence and Different Output Modes

With an AC input of 230 V/50 Hz, the Stream Ultra delivers a nominal power of up to 800 W, with a maximum output current of 3.48 A. The maximum input power is 2,300 W and the power factor is adjustable from 1 to 0.8. The AC output provides power to devices with a continuous power of 1,200 W (1,200 VA), with a maximum current of 5.22 A and an input power of 800 W. In Bypass mode, the maximum output current is 10 A, ensuring reliability even with high loads. For applications that require more power, the system offers a parallel connection mode of up to 2,300 W, ensuring flexibility and scalability for larger installations.

Performance under All Conditions

The EcoFlow Stream Ultra operates without problems in a temperature range from -20°C to 55°C, with a relative humidity of 5% to 95%. It can be safely stored at temperatures from -20°C to 55°C and its design allows it to operate at elevations of up to 4,000 meters above sea level, making it the ideal choice for applications in difficult environments, from high mountains to hot deserts.

Smart Management and Connectivity

The device offers Bluetooth and WLAN connectivity, with complete control and management through the dedicated EcoFlow app. This provides the user with access to real-time data and the ability to monitor and optimize system performance remotely.
