Victron & MG Energy Systems battery solutions

Introduction

MG Energy Systems (MG) develops and produces advanced battery systems for Marine, Solar/off-grid, industrial and mobile applications. The roots of the cooperation with Victron Energy goes back to 2011 when we developed our first Lithium-Ion battery systems and these were added to Victron’s product range. A development cooperation was setup to achieve maximum compatibility, performance, functionality and safety between our battery systems and Victron’s inverter/chargers. This close development is still an ongoing process. From Master BMS firmware development with new functions to GX products scripts and GUI to extend functionality and compatibility.

400 kWh ESS system (80x HE200Ah + 1x Master LV 1000A)

Products

MG has developed a complete range of products with all the same philosophy to provide modular and scalable solutions from 12 VDC to 800 VDC. Each battery system consists out of the following:

Different setups can be created at different voltages and capacities. The most common to connect to Victron equipment is a Master LV in combination with one of the battery module series from 12 VDC to 48 VDC. For support information you can contact support@mgenergysystems.eu.

 MG Master LV

Product compatibility

MG is the only battery system provider that has VE.CAN implemented in the Master BMS. This has the advantage to directly control VE.CAN equipment on this communication bus like VE.CAN MPPT’s and skylla-I’s. Another advantage is that the VE.CAN bus can be connected to the existing NMEA2000 CAN-Bus networks. The default selected mode for the VE.CAN on the GX products (CCGX, Octo GX, Venus GX and CANvu GX) is used.

CAN-bus profile

GX products requirement

One of the GX products needs to be connected in between the Master BMS and inverter/chargers with VE.Bus or VE.Direct to provide charge and discharge control by DVCC. The GX products work like an advanced gateway.

  2. Requires VE.Direct remote on-off cable non-inverting

Firmware

To have the best functionality it is recommended to update all firmware of the devices used in a system to the latest release version. The firmware of the MG Master LV (Lynx BMS) can be update by CAN-Bus locally with the “Diagnostic Tool” (Lynx BMS Tool) or by a GX product remotely on the VRM portal. Updating the Master LV (Lynx BMS) will also update the battery module connected to it automatically if necessary. This will have the advantage that the battery modules are always compatible with the connected Master LV.

System setup examples

Basic 1 phase setup

Basic 3 phase setup

Redundant system setup

Below an example of a 600 kWh redundant battery system setup with solar connected to the DC.

The GX products redundant/combined battery support

Different Master LV’s in one system can be combined in the GX products to see it as one battery.

The combiner can be enabled in the System Setup menu. The Master LV’s (Lynx Ion BMS) which need to be combined can be selected. The new combined battery can be given a new device instance. This will make it also available and can be easily identified on the VRM portal.

The new combined battery will be created in the device list and can be selected as the battery monitor to have parameter control by DVCC. If one the Master LV’s (Lynx BMS) fails, the system will stay active and keeps operating.
