The EcoFlow STREAM AC is a plug-and-play home battery that stores 1920 Wh in a 21.2 kg cabinet measuring 25.5 x 25.4 x 45.8 cm. It plugs into a standard household socket, charges from the grid at up to 800 W and feeds excess energy back through the same connection at up to 800 W - no PV input, no external inverter. The battery is intended to be the final unit at the end of a STREAM chain, and up to six batteries can be linked to reach a combined 11 520 Wh. The IP65 housing and self-heating chemistry keep it usable in unheated garages or outdoors.

• 1920 Wh usable per unit, stackable to 11 520 Wh across six batteries in one chain.
• Grid charging and grid feed-in of up to 800 W through the same wall socket.
• Always the final unit in a STREAM series; use the STREAM AC Pro if further daisy-chaining is needed.

• 6000 cycles down to 70% capacity, backed by a 10-year warranty.
• Full app control over Wi-Fi and Bluetooth with support for EcoFlow Smart Meter 120A, Shelly Pro 3EM, Homey P1, Shelly 3EM and Tibber Pulse.
