Description
Sub-second grid monitoring for strict feed-in limitation.
EcoFlow Smart Meter is an industrial-precision single and three-phase smart energy meter engineered to measure household electrical exchange at the main utility point of common coupling, enabling sub-second dynamic zero-export compliance and optimized solar self-consumption for PowerOcean and OCEAN 2 hybrid systems.
Sub-Second Dynamic Zero-Export Control
Delivers instantaneous power telemetry to EcoFlow hybrid inverters to modulate battery charging and prevent unauthorized grid feeding.
High-Precision Class 1.0 Energy Tracking
Accurately measures household active power import, export, voltage, and current in real time.
Universal 1-Phase / 3-Phase Domestic Compatibility
Installs seamlessly across standard 230 V single-phase and 400 V three-phase domestic electrical switchboards.
Compact 35 mm DIN-Rail Breaker Panel Mount
Snaps cleanly onto standard DIN rails inside the main distribution board with negligible standby power draw.
More product details
Utility regulations in many European regions strictly cap or prohibit solar grid feed-in without approval. The EcoFlow Smart Meter measures power exchange at the grid boundary, commanding inverters to throttle output instantaneously.
- High-speed RS485 Modbus telemetry loop updates inverter power dispatch in under 1 second.
- Ensures compliance with local utility zero-export and percentage-based feed-in caps.
- Measures active, reactive, and apparent power across all three lines simultaneously.

Real-time whole-home energy flows in the palm of your hand.
Homeowners need clear visibility into how much energy their solar array generates, what the house consumes, and how much power is drawn from the grid. Displays live 24/7 power flow diagrams, daily consumption curves, and historical self-sufficiency ratios. Directly coordinates with EcoFlow Smart Plugs and EV chargers to automate solar surplus diversion. Standard 35 mm DIN-rail mount (4U width) fits standard domestic electrical panels.
Holds self-consumption at the grid point
The reading is total site import and export. Self-consumption optimisation uses that figure, not the backup-side subset.
Holds the export limit at the grid point
Export limiting needs the full feed-in figure. Loads outside backup would otherwise stay invisible.
Fits first-generation PowerOcean plants
Gen-1 PowerOcean has no built-in meter. This unit is the grid-point meter on those plants.
Technical data
High-speed grid telemetry engineered for dynamic zero-export and automated home energy optimization.
External grid-point smart meter for dynamic solar tracking and whole-home balancing.
Purpose-built to measure total household electrical exchange at the main utility connection point, the EcoFlow Smart Meter provides high-speed power data for PowerOcean and OCEAN 2 hybrid systems. It enables dynamic zero-export regulation, real-time solar tracking, and intelligent multi-appliance load balancing inside the EcoFlow mobile app.

Can the EcoFlow Smart Meter work with both single-phase and three-phase systems?
Yes. Supports both 1-phase 2-wire and 3-phase 4-wire electrical connections. The meter features configurable internal wiring terminals, supporting single-phase 230 V (1P2W) or three-phase 400 V (3P4W) installations with the same physical hardware.
