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.
The following MG products are fully compatible with (VE.Can) NMEA2000.
Digital control of Victron Energy chargers/inverters is called Distributed Voltage and Current Control
, DVCC. The charge voltage, charge current and discharge voltage and current is controlled by the MG Master BMS. When an MG battery system is almost charged the charge voltage is lowered and that results in a lower charge current. If the MG battery system is fully charged it stops the charging process completely.
When DVCC functionality is used, the
two wire BMS assistants
in the MultiPlus or Quattro devices are not required. If this is configured then it must even be removed to have a proper working system.
Update all Quattro's/Multi's/Solar MPPT's/GX device and MG Master LV to the latest firmware.
Always update all connected devices to the latest firmware available.
Required minimum firmware versions (can be obtained from the Victron professional
website):
All components must be digitally connected to the GX device. Either by VE.CAN, VE.Direct or VE.Bus.
Digitally controlled devices:
In this step the MG Master LV settings are checked.
External CAN-Bus protocol
is set to MG NMEA2000
. When this is properly set the name in the GX's device list will begin with MG ...
.Combined battery mode
must be Enabled
.Battery monitor
: Go to Menu
-> Settings
-> System setup
-> Battery monitor: set to MG Master LV, MG SmartLink MX / PLC or MG Master HV
.Menu
-> Settings
-> DVCC
-> DVCC: Enable
.Controlling BMS
(only for GX firmware version 3.00 or higher): Go to Menu
-> Settings
-> DVCC
-> Controlling BMS
: set to MG Master LV, MG SmartLink MX / PLC or MG Master HV
The
Controlling BMS
can only be selected when it is inRunning
mode. This means a MG SmartLink MX must have a MG Master LVRunning
(main safety contactor closed).
With a Victron Energy GX device that has the latest released software version V2.60 or higher, it is possible to change the device instance of a MG Master LV, MG Master HV or SmartLink MX.
On the Victron Energy GX device, go to: Settings
-> Services
-> VE.CAN port
-> Devices
-> MG BMS
or MG SmartLink MX/PLC
-> Device Instance
.
The number shown on the VRM website is not the same as the
Device instance
! This is the VRM instance and can be found at the device information (Example: MG BMS 400A -> Device -> VRM instance).
Some of the MG products have support to update firmware using Victron's VRM portal.
The Victron Energy GX device must be powered from the MG Master LV auxiliary power output at connector
A
.
The MG Master LV will open its main safety contactor during updating. This means the power on the system will be down. The Victron GX device will also reboot.
MG Master LV - All versions
Victron Lynx Ion BMS - All versions
Use the following steps to update to a custom firmware version using Victron's VRM portal.
You need a .vup firmware file from MG in order to perform the update.
For A MG Master LV select the MG_MasterLv_Vx.xx.vup.
For a Victron Lynx Ion BMS select Lynx_ion_bms.app.Vx.xx.vup.
Device list
and check for the battery monitor type. Send an email to support@mgenergysystems.eu with the device type and ask for the .vup file.Select file
and select the new firmware .vup file.
