EcoFlow STREAM Ultra + STREAM AC Pro

The EcoFlow kit is a complete plug-and-play energy solution that enables the storage and use of energy from photovoltaic panels - both day and night. It includes the EcoFlow STREAM Ultra 2-in-1 smart energy storage system with microinverter and an additional EcoFlow STREAM AC Pro energy storage unit. The systems form a cohesive balcony system that supports the home’s electrical system, reduces electricity bills, and provides backup power - without complicated installations or unnecessary wiring.

EcoFlow STREAM Ultra – energy storage and inverter in one

The EcoFlow STREAM Ultra is an advanced energy storage system with a microinverter that allows maximum use of energy from photovoltaic panels (not included). With a capacity of 2 kWh and support for up to four independent MPPT inputs (up to 500 watts each), the system excels at managing solar power even with an input power of up to 2,000 watts. It can transfer energy to a home installation with an output of up to 800 W (AC Grid Terminal) and power devices from the AC output (up to 1,200 W). With parallel operation (up to 2,300 W), the system can be expanded into larger solutions. The IP65-rated housing, quiet fanless operation, and weather resistance (-20°C to 55°C) ensure reliability both indoors and outdoors.

EcoFlow STREAM AC Pro – extra capacity and flexibility

The EcoFlow STREAM AC Pro energy storage unit is a plug-and-play device with a capacity of 1.92 kWh that can operate independently or as part of a larger energy system. It can be charged directly from a wall outlet and then power household appliances up to 1,200 watts or feed energy back into the grid with a maximum output of 800 watts. During discharge, it automatically switches to bypass mode, supplying grid power up to 2,300 watts. The EcoFlow STREAM AC Pro features a self-heating function that enables charging even at low temperatures, and the robust, compact IP65-rated housing allows safe use both indoors and outdoors.

Smart energy management – remotely and on the go

The two devices - EcoFlow STREAM Ultra and EcoFlow STREAM AC Pro - offer Bluetooth and Wi-Fi connectivity and can be operated via the EcoFlow app. Through the app, energy flow can be monitored in real time, battery charge levels can be checked, charging and discharging schedules can be set, and various functions can be activated at will. The app also allows remote switching of the devices on and off and integration into smart AI scenarios - some of which are available as part of the premium version.

A lifespan you can rely on

The EcoFlow STREAM Ultra and EcoFlow STREAM AC Pro are equipped with batteries that provide over 6,000 high-performance charging cycles. This means the set is ready for years of intensive use.
