SDM01 G2X

Compact Energy Meter with Clamp CTs

The SDM01 G2X is an ultra-slim 18mm energy meter for precise three-phase or multiple single-phase monitoring. It delivers high-speed reporting for dynamic load balancing and export limiting, alongside an external antenna for reliable connectivity.

- Bi-directional Measurement: Measures power and energy flow for both consumption and generation.
- Easy Installation: Compact 1-module width (18mm) DIN rail design, paired with easy-to-install split-core CTs.
- Fast Measurement: Captures precise RMS power data within 150ms, enabling rapid response for PV, EVSE, and ESS systems.
- Flexible CT Compatibility: Freely match with any official 120A/Φ16 CT to maintain Class 1 accuracy—no factory recalibration required, simplifying field maintenance.
- External Antenna: Equipped with an external antenna to ensure robust WiFi connectivity, easily overcoming signal shielding from metal distribution boxes.
- Local API: Rich local APIs (HTTP, MQTT, UDP, Modbus TCP, WebSocket etc) to meet diverse integration needs.
