It measures a wide range of electrical parameters and communicates via RS485 Modbus RTU, making it compatible with most major solar inverter brands for export control and self-consumption monitoring.\u003c\/p\u003e\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSingle phase DIN rail meter with 100mA CT included\u003c\/li\u003e\n\u003cli\u003eMeasures kWh, kVArh, kW, kVAr, kVA, PF, Hz, V, A and more\u003c\/li\u003e\n\u003cli\u003eBi-directional measurement: import and export\u003c\/li\u003e\n\u003cli\u003eRS485 Modbus RTU communication\u003c\/li\u003e\n\u003cli\u003eTwo configurable pulse outputs\u003c\/li\u003e\n\u003cli\u003eWhite backlit LCD display\u003c\/li\u003e\n\u003cli\u003eBetter than Class 1 accuracy\u003c\/li\u003e\n\u003cli\u003eCompact DIN 43880 format, 35mm rail mounting\u003c\/li\u003e\n\u003cli\u003eIP51 ingress protection (indoor use)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\u003cp\u003eThis meter is designed for use in residential, utility, and industrial single phase applications. Its bi-directional energy measurement capability makes it well suited to solar PV monitoring, allowing the inverter or energy management system to track both consumption from the grid and any surplus export.\u003c\/p\u003e\u003cp\u003eThe RS485 port supports Modbus RTU at baud rates of 1200 to 9600 bps, with configurable parity, stop bits, and Modbus address (1 to 247). Pulse output 1 is user-configurable for total, import, or export kWh or kVArh. Pulse output 2 is fixed at total kWh at 1000 imp\/kWh.\u003c\/p\u003e\u003ch3 style=\"color: #f87c24;\"\u003eInverter Compatibility\u003c\/h3\u003e\u003cp\u003eThe SDM120CTM 100mA is used as the export\/import meter for a wide range of solar inverter brands including Solis, Growatt, Deye, SolaX, Sungrow, FOXESS, Hypontech, Kstar, and others. Always confirm the correct CT output rating (100mA) and Modbus version required by your inverter before ordering.\u003c\/p\u003e\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSolar PV export and self-consumption monitoring\u003c\/li\u003e\n\u003cli\u003eZero export control with compatible hybrid inverters\u003c\/li\u003e\n\u003cli\u003eResidential and small commercial energy metering\u003c\/li\u003e\n\u003cli\u003eDIN rail panel installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3 style=\"color: #f87c24;\"\u003eInstallation and Safety Notes\u003c\/h3\u003e\u003cp\u003eThis meter operates at mains voltage and must be installed by a qualified electrician in accordance with IET Wiring Regulations.
