EcoFlow STREAM Ultra 1920 Wh Speicher

EcoFlow STREAM Ultra 1920 Wh – the all-in-one hybrid system for minimal electricity costs

Make your home solar-powered: The EcoFlow STREAM Ultra combines storage and intelligent energy management in one system. Many household appliances consume over 800 W – with the STREAM Ultra, you can power them with up to 2,300 W entirely from solar energy and become step-by-step more independent from the grid.

Your benefits at a glance

More runtime through scalable storage and solar inputs

The STREAM Ultra grows with your needs: from 1.92 kWh up to 11.92 kWh storage capacity and from 2 kW (4 MPPT) up to 12 kW (24 MPPT) PV input – with up to 6 connected units. Two units can be easily coupled to double the capacity or combined with batteries from the EcoFlow DELTA series.

Time-of-Use (TOU) – making the most of dynamic electricity tariffs

Charge when electricity prices are low – feed in when they are high. The AI-based TOU model analyzes tariff data from platforms like Nord Pool, EPEX SPOT, Rabot Energy, Octopus, and others every 60 minutes, providing you with the optimal savings strategy at all times.

Smart Meter × Smart Plug: no feed-in, purely solar

EcoFlow works with leading smart energy brands like Shelly, Tibber, and others. Using smart meters, smart plugs, and the EcoFlow app, you can automatically run devices like garden irrigation, e-bikes, or ventilation systems using surplus solar energy.

EcoFlow AI Assistant: no calculation, just savings

The AI assistant takes over energy management: It analyzes data, identifies weaknesses, and provides clear, actionable recommendations – smart decisions without the guesswork.
