EcoFlow STREAM AC

EcoFlow STREAM AC – Extension battery for modular energy systems

The EcoFlow STREAM AC is a pure extension battery designed to complement existing EcoFlow STREAM systems. Unlike the STREAM AC Pro model, it does not have its own AC output. Instead, it is available as a scalable storage unit and is ideal for expanding the overall capacity of STREAM systems.

Scalable storage capacity for larger requirements

With a capacity of 2 to 12 kWh, the STREAM AC can be individually adapted to different energy needs. Whether for households with high self-consumption, for retrofitting existing systems, or as a backup component – ​​the STREAM AC integrates seamlessly into the EcoFlow ecosystem.

Robust, weatherproof and space-saving

• Pure extension battery – without AC output
• Scalable capacity from 2 to 12 kWh
• IP65 certified – for safe outdoor use
• Compact housing with reduced space requirements
• 800W fuse for additional safety

Integrated into the EcoFlow energy management

The STREAM AC is controlled via the EcoFlow app and integrated into the central energy management system. Consumption patterns, storage status, and charging behavior can be monitored in real time and efficiently managed – thanks to integrated AI support and app integration.

Reliable addition to existing systems

The STREAM AC is suitable for all users who are looking for a powerful storage solution to expand their STREAM systems – without its own AC output, but with full integration into the EcoFlow ecosystem.

Technical highlights
