The EcoFlow STREAM AC Pro is a Plug & Play home battery aimed at homes that already have a solar inverter and only need extra storage. It offers 1920 Wh of usable capacity per unit and can be scaled up to 11.52 kWh by chaining up to six AC Pro or AC batteries in parallel. The 22.8 kg housing measures 25.5 × 25.4 × 45.8 cm, is rated IP65 and self-heats below 5 °C so it can be installed in a garage, garden shed or utility room.

• 1.92 kWh per unit, expandable to 11.52 kWh with up to six STREAM AC Pro or AC in parallel
• Charges from the mains at up to 1050 W – this model does not accept direct solar input (see STREAM Pro or Ultra for that)
• Feeds up to 1200 W back to the home on a dedicated circuit, 800 W on a shared group
• Integrated sockets deliver 1200 W plus 1100 W pass-through for up to 2300 W of appliances
