MG SmartLink MX CANbus Interface

MG SmartLink MX CANbus Interface

MG SmartLink MX CANbus Interface

The MG SmartLink MX combines data from multiple MG Masters (HV/LV) into a single virtual battery bank. It connects via CAN bus (NMEA2000) or Modbus TCP to Victron GX, SCADA, PLCs, and chargers—essential for professional energy systems. This offers installers and system integrators significant benefits in terms of scalability, overview, and compatibility. The SmartLink MX supports both low (LV) and high (HV) voltage setups and works completely plug-and-play via CAN bus, requiring no additional configuration. This module: * Combines BMS data via CAN‑bus or Modbus TCP into one virtual battery bank * Supports MG Master control: start, stop, reset of battery system with integrated regulation * Contains 3 programmable relay outputs (0.8 A @ 60 VDC) plus 1 digital output for charge/discharge status * Operates via NMEA2000 CAN‑bus, with Modbus TCP connection capability, and control without external EMS/PMS, compatible with Victron Cerbo GX and other GX devices from Victron Energy With support for up to 15 MG Masters, power range 8–60 VDC and consumption around 1 W, the SmartLink MX offers robust performance and high system latitude. Installation is easy: DIN‑rail mounting system, RJ45 terminators on CAN bus, power via Aux‑power outputs from MG Masters (single or multi-master setup). Firmware updates possible via MG Connect app or Diagnostic Tool. The Bluetooth connection enables fast and secure configuration, monitoring, and updating — wirelessly and without a laptop, ideal for installers and system integrators in the field. Benefits for installers & integrators: * Combines MG Masters into one clear system * Makes scalable energy solutions easy * No configuration required — plug and play * DIN-rail mounting, lightweight and robust * Reliable CANbus interface with high compatibility * Seamless integration into the Victron eco-system Type approval: Besides the SmartLink MX, there is also the SmartLink PLC. The SmartLink PLC has the same features and qualities, and in addition is type approved for class registers. Q&A overview: * Compatibility: MG Master HV & LV, Victron GX, SCADA, PLC, chargers via NMEA2000 or Modbus TCP. * Number of Masters: Supports up to 15 Masters in combined or standalone mode. * Data output: CAN‑bus (NMEA2000), Modbus TCP. * Relay outputs: 3 relays (0.8 A) and 1 digital output – flexibly programmable for status and fault signalling. * Power: 8–60 VDC, max 1 A, power source via Aux pins of Master(s). * Configuration: Plug and play or advanced with MG Diagnostic Tool/MG Connect app. * System control: Start, stop, reset via control or app. In combined mode: chooses start/stop sequence of Masters. * Installation: DIN rail, CAN bus terminators required, power via Masters (not direct from battery). * Firmware: Updateable via app or tool — firmware v1.14+ supports extended settings. * Usage: Redundancy, scalability, clarity, and professional integration with external systems.
