EcoFlow STREAM AC Solar Battery 1.92 kWh – Storage Expansion for STREAM Systems

Anyone who wants to use self-produced solar energy in the evening needs storage. Anyone already running an EcoFlow STREAM system needs the STREAM AC. This add-on battery expands the storage capacity of an existing STREAM system by 1.92 kWh – and up to six times if needed, for a total capacity of 12 kWh. No restart, no new configuration, no compromise.

Who is the STREAM AC designed for?

The STREAM AC is aimed at anyone who wants to expand their existing EcoFlow STREAM system – whether to increase self-consumption, as a retrofit after the first year of operation, or as a backup power reserve for extended outages. The battery has no solar input of its own; it charges exclusively via the 800 W AC charging input, making it a pure, uncompromising storage solution.

Modular up to 12 kWh – grows with your needs

EcoFlow's modular principle is consistently applied here: up to six STREAM AC units can be combined with an existing STREAM system, enabling a total capacity of up to 12 kWh. Start with one unit today and add more tomorrow – without replacing or reconfiguring the system. The STREAM AC integrates automatically into the existing configuration.

800 W AC input and output – enough for everyday life

With 800 W of AC charging power, the STREAM AC charges quickly – and with 800 W of AC output, it reliably powers all typical household appliances. Whether it's a fridge, washing machine, or work device: in grid-connected operation, power flows exactly when it's needed.

IP65 – robust enough for outdoors

With IP65 protection, the STREAM AC is shielded against dust and water jets, making it suitable for installation both indoors and outdoors – on a balcony, terrace, or in the garden. The integrated self-heating function activates automatically at temperatures below 5 °C to maintain charging efficiency even in winter.

App control and intelligent energy management

All connected STREAM components are managed together via the free EcoFlow app. Charge level, power flow, consumption, and system status are visible in real time – from your smartphone, from anywhere. The app detects the STREAM AC automatically and integrates it into the existing system without any manual configuration.
