It combines advanced battery technology, smart control, and maximum flexibility – ideal for decentralized power supply in the home, garden, or off-grid setups.

Set contents:

• 1× EcoFlow STREAM Ultra – hybrid battery with integrated inverter, four MPPT inputs & AI-based consumption optimization
• 1× EcoFlow STREAM AC – pure extension battery without its own AC output, for flexible capacity expansion
• 1× EcoFlow STREAM parallel connection cable – for safe parallel connection and system expansion

Powerful technology for efficient energy management

The STREAM Ultra offers maximum flexibility in solar connection thanks to four independent MPPT inputs (500 W each). With up to 2,300 W output power, IP65 protection, and an integrated AI system, the energy flow is precisely controlled and optimized. Combined with the STREAM AC, this creates an expandable storage system with a total capacity of 3.84 kWh—perfectly tailored to your individual energy needs.

Scalability & future-proofing

Thanks to the included parallel connection cable, the system can be easily expanded. The STREAM AC functions purely as a storage extension, without its own Schuko outlet, but is fully integrated into the EcoFlow ecosystem. With up to 6,000 charging cycles and a 10-year warranty, you're investing in a long-lasting, future-proof energy system – ideal for growing households or the transition to an energy-independent future.
