The EcoFlow Smart Meter 120A is a DIN-rail energy meter designed to sit inside the fuse box and measure whole-house current on either a single-phase or three-phase feed. The 90 x 66 x 36 mm housing occupies two DIN positions and includes three 30 x 30 x 50 mm split-core clamps that close around the live conductors after the main breaker. Its own draw is only 48 mA, and readings reach the EcoFlow app over 2.4 GHz Wi-Fi with Bluetooth for the initial handshake. Once online, it feeds real-time import and export values to any paired STREAM battery.

• Suits single-phase or three-phase installations; only the first clamp is used in mono-phase.
• Split-core clamps fit conductors between 0.5 and 2.5 mm², keeping installation non-invasive.
• Reports live import and feed-in figures per phase to the EcoFlow app.
• Enables self-consumption logic in STREAM home batteries.
• Works from -25 °C to 70 °C, tolerating cold garages and warm meter cabinets alike.
• Own consumption of 48 mA keeps the meter almost invisible on the bill.
