Victron MG Energy: Master BMS Setup Guide

Key Takeaways

• High-end lithium specialization: MG Energy Systems (MG) specializes in high-end lithium-ion battery system solutions, featuring innovative technologies for the best performance.
• Target application scope: These lithium-ion battery systems are ideal for full-electric and hybrid marine propulsion systems, off-grid/Solar, machinery and vehicle applications.
• Historical development partnership: The cooperation with Victron Energy goes back all the way to 2010. Back then we started developing our first Lithium-Ion battery systems. These battery systems were added to the Victron product range.
• System voltage scalability: Modularity and scalability lay the basis of the MG system philosophy. As a result MG offers system solutions from 12 Vdc up to 900 Vdc.
• Standard low-voltage platform: Easily create different setups at different voltages and capacities. When creating an MG Victron system set up, the most common is a 12 Vdc to 48 Vdc system. This includes the Master LV in combination with one of the battery series.
• Exclusive native VE.Can protocol: MG is the only battery system provider that has VE.CAN implemented in the Master BMS.
• Direct bus equipment regulation: This has the advantage to directly control VE.CAN equipment on this communication Bus like VE.CAN MPPT’s and skylla-I’s.
• Marine NMEA2000 compatibility: Another advantage is that the VE.CAN can be connected to the existing NMEA2000 CAN-Bus networks.
• Standard GX controller profile: The default selected mode for the VE.CAN on the GX products (Cerbo GX, Octo GX, Venus GX and CANvu GX) is used.
• Joint safety and performance goals: To achieve maximum compatibility, performance, functionality and safety between our battery systems and Victron’s inverter/chargers, we decided together that it would be beneficial for both to set up a development cooperation.

System Architecture & Master BMS Philosophy

MG Energy Systems delivers advanced lithium energy storage solutions built on an exclusive native VE.Can architecture developed in close partnership with Victron Energy.

The Victron and MG Energy Systems integration combines Master LV and Master HV controllers with native VE.Can implementation across a 12Vdc to 900Vdc range, featuring direct Skylla-i / MPPT control and NMEA2000 bus bridging:

• Master BMS Architecture: Native VE.CAN in BMS, Master LV 12V-48V, Default VE.Can Mode, Integrated Contactor.
• Direct Bus Control: Direct VE.Can MPPT, Direct Skylla-i, No Extra Bridges, Cerbo/Venus GX Compatibility.
• Marine & Scalability: 12V to 900Vdc, Marine NMEA2000, Joint Development Partnership, Maximum Safety.
