Battery Management System
All in One Design
12 Vdc up to 96 Vdc
Safe Operation
Fully Scalable
The Master LV is the BMS for low voltage systems. The main function is protecting the connected batteries. The internal BMS collects the data and monitors all essential battery parameters. This way, the Battery Management System preserves the health of your system. The BMS will always make sure that the parameters will stay within a safe operating window. When exceeding the safe operating window, the internal safety contactor opens automatically. This will disconnect all chargers and loads. As a result, the Master LV guarantees a safe and reliable operation.
In addition, the Battery Management System balances the cells of the entire battery installation. This maximizes the capacity and increases the battery cell lifetime. Each MG battery has a built-in slave BMS. This monitors all individual cells in the battery module. The Master LV collects all this data, and intervenes when needed. This way it protects all batteries.

Easy Installation
The Master LV is easy to install thanks to the all in one design. It requires less cables, equipment and installation components. This results in a quick Plug and Play installation. The integrated CAN-Bus protocol automatically detects your system configuration. Moreover, it updates the firmware of all batteries.
Can-Bus Communication
With the built-in CAN-Bus connectors the Master LV communicates with the MG batteries, chargers/loads and third party devices. The two left side ports are reserved for communication with the batteries. The two right side ports are for auxiliary communication. Different CAN-Bus protocols are available in the BMS software. NMEA2000 is the most common protocol. The Master LV includes both RJ45 and M12 connectors. This makes it suitable for any application.
MG Connect App
Monitor and control the MG Master LV with your smartphone or tablet. Easily enable bluetooth by tapping the green start button three times. Download the MG Connect app in the Play Store or App Store. The Connect App works fast and intuitive and provides direct insight into your system.

System Redundancy
Combined Battery Banks
Another unique feature of the Master LV is the ability to create a redundant battery system. In order to achieve this, use the software and configure two or more Masters LV in “Combined mode”. Use the combined mode to create large and fully scalable storage systems. Moreover this creates redundancy of your battery bank. This ensures that the battery system will be operational at all times. In many cases it is required to design redundant battery banks. This guarantees maximum system reliability.
For battery systems in combined mode, use the SmartLink MX. The SmartLink collects and combines the data from all the connected Battery Management Systems. It transmits the data onto the CAN-Bus and makes this data available for third party devices. Furthermore, the SmartLink MX provides the necessary controls to start, stop and reset the battery system.
Typical examples of combined battery banks are: marine propulsion systems, large solar & off-grid installations and industrial applications.

Safety & Protection
Battery Management System
The Master LV is exclusively designed for low voltage applications. Create a safe installation in the range of 12 Vdc up to 96 Vdc. The BMS measures the voltage and temperatures of the connected battery modules. Moreover, it protects the battery modules against any exceeding parameters. Furthermore the Master LV controls the balancing on both cell and module level.
Protecting, monitoring and controlling a battery system is very important to create a safe and reliable system. The MG system philosophy is to have one or more Masters LV connected to the lithium-ion battery bank. Each MG battery module contains an integrated slave BMS. This slave BMS monitors the battery cell parameters actively. It measures cell voltage, cell temperature and controls the cell balancing. All these parameters are sent to the Master LV over CAN-Bus. The Master BMS collects the data and keeps the entire installation at the highest safety level.

DC Distribution
The design of the Master LV includes an internal DC-busbar. Easily connect the MG batteries on the left side. The right side of the Busbar is reserved for all kinds of chargers and loads. For example, directly connect your battery charger, electric drive and inverter on the right side. The insulation caps separate the positive and negative terminal from each other. Use a MEGA-Fuse for each positive terminal.
Safety Contactor
When starting up your Master LV, the safety contactor links the left side with the right side of the busbar. During the start-up, no sparks and welding occur thanks to the built-in pre-charge circuit. When shutting down your system it disconnects the batteries from the chargers and loads. Moreover, the contactor opens in case a critical parameter exceeds the limit. This is a second layer of protection.
I/O Connectors
The Master LV comes with two integrated I/O ports. To sum up some of the functions:
Allow to charge Allow to discharge 12 Vdc – 1 A Auxiliary output Programmable Relay. To start a generator, or heater. Remote Start-Stop button
