Deye Single Phase Smart Meter & CT 

SKU: SDM120CTM-40mA

The Deye - Single Phase Smart Meter & CT (SKU: SDM120CTM-40mA) is a compact, single-module DIN-rail bidirectional energy meter supplied with a 120A/40mA split-core current transformer (ESCT-TA16) for accurate solar PV metering and export control in Deye inverter systems. Designed for single-phase two-wire applications, this multifunction meter measures and displays import and export active energy (kWh), reactive energy (kVArh), voltage, current, active/reactive/apparent power, power factor, and frequency on a white backlit LCD screen. Featuring RS485 Modbus RTU communication, Class 1 active energy accuracy, and an ultra-slim 18 mm width, the SDM120CTM-40mA fits effortlessly into crowded residential and small commercial switchboards.

Key Features: Deye - Single Phase Smart Meter & CT

• 40mA Micro-CT Input & Included Split-Core CT: Engineered specifically for 40mA secondary output CTs and supplied with a 120A/40mA split-core CT (ESCT-TA16) for non-invasive clip-on switchboard installation.

• Bidirectional Solar PV Metering: Tracks both import and export active energy independently with Class 1 accuracy (IEC 62053-21), making it ideal for solar net metering and zero-export control.

• RS485 Modbus RTU & Dual Pulse Outputs: Equipped with an isolated RS485 Modbus RTU port (1200 to 9600 bps, addresses 1 to 247) for seamless inverter communication, plus two passive pulse outputs.

• Ultra-Compact 1-Module DIN-Rail Design: Measures just 18 x 119 x 62 mm (DIN 43880) to save valuable switchboard space on standard 35 mm DIN rails while consuming less than 2 W / 10 VA.

• White Backlit LCD Display: Provides clear local readout of total kWh, import/export kWh, voltage, current, active power, frequency, power factor, and Modbus parameters via a front scroll button.

• Durable & Flame-Retardant Housing: Built with self-extinguishing UL94V-0 material, IP51 indoor sealing, and 4 kV AC / 6 kV impulse voltage withstand across operating temperatures from -25 to 55 degrees C.
