Description
The MG SmartLink MX is a battery controller and data combiner for systems built from two or more MG Master LV or Master HV units. It collects and combines all data from the connected masters and transmits it over CAN-Bus, so parallel connected battery strings are presented to the rest of the vessel as a single battery bank. A protocol based on NMEA2000 makes the combined data available to chargers, electric drives and other third party devices without a separate energy or power management system.
Beyond combining data, the SmartLink MX controls the MG masters and provides the controls to start, stop and reset the entire battery system, detecting system warnings and errors as they occur. Three programmable relay outputs with selectable switching modes, such as combined allowed-to-charge and allowed-to-discharge, simplify the wiring to external equipment, and the MG Connect app adds Bluetooth monitoring and configuration.

When do I need an MG SmartLink MX?
Use the SmartLink MX for battery systems built from two or more MG Master LV or Master HV units. It collects and combines the data from all the masters and presents parallel connected systems as a single battery bank, and it can combine up to 15 MG BMSs.
How does the SmartLink MX communicate with third party devices?
It transmits the combined battery data over CAN-Bus using a protocol based on NMEA2000, so chargers, electric drives and other third party devices no longer need to poll each individual BMS. No separate EMS or PMS is required because direct control is possible.
What control and I/O does the SmartLink MX provide?
It provides the controls to start, stop and reset the whole battery system and detects system warnings and errors. Three programmable relay outputs (0.8 A at 60 Vdc, potential free) with selectable switching modes such as combined allowed-to-charge and allowed-to-discharge simplify wiring to external devices.
