The EcoFlow STREAM Max is a hybrid plug-in home battery that packs 1920 Wh of storage into a 22 kg cabinet measuring 28.4 x 25.5 x 45.8 cm. It combines direct PV input, grid charging and an on-board socket, and it can grow up to 11 520 Wh when stacked with additional STREAM batteries. The Max always sits as the final unit in a chain, because it has no downstream pass-through connector. All configuration runs through Wi-Fi and Bluetooth in the EcoFlow app, and the LFP-style chemistry is rated for 6000 cycles down to 70% of the original capacity.

• 1920 Wh usable per unit, stackable to 11 520 Wh across six batteries.
• Direct solar input up to 2000 W (2 x 500 W modules with headroom for larger arrays).
• Grid charging up to 1050 W and grid feed-in of 800 W on a shared circuit or 1200 W on a dedicated one.
• Integrated socket supplies up to 1200 W from the battery plus 1100 W pass-through for 2300 W total.
• IP65 housing, <30 dB acoustic signature and self-heating below 5 °C support outdoor placement.
• Works with the EcoFlow Smart Meter 120A, Shelly Pro 3EM, Homey P1, Shelly 3EM and Tibber Pulse for self-regulating operation.
