Smart Energy Management — Simply via App

The EcoFlow App integrates all components of your system into a smart ecosystem. With integrated AI, it analyzes consumption patterns, optimizes energy flows, and thus reduces electricity consumption from the grid — automatically and in real-time. This allows for efficient use of stored energy from devices like the DELTA Lite AC or extra batteries in the STREAM AC Pro configuration.

The battery flexibly adapts to various living situations — whether in the living room, utility room, or on the balcony. Installation can be planned decentrally, reducing space requirements by up to 50%. Its compactness and IP65 moisture protection make the solution convenient for outdoor placement next to solar panels on the balcony.
