¶ Introduction
The Micropower charger that can be used to charge MG battery systems is CAN bus controlled and air-cooled. There are different models available with multiple voltage and current ratings.
¶ Compatibility
The Micropower chargers can only be controlled by CAN bus. It can be controlled by MG Master LV, HV and SmartLink MX.
¶ MG Master LV / HV
- External CAN bus protocol:
MG NMEA2000 - Maximum supported chargers:
15
¶ MG SmartLink MX
- Minimum firmware version:
All versions(CAN-A),V1.14 (CAN-A and CAN-B) - Maximum supported chargers:
6
¶ Supported chargers
The table below shows the available versions that are supported by MG equipment. All these chargers can be CAN bus controlled. For these chargers, a CAN bus adapter cable is needed:

¶ Schematic example
The schematic below shows a system example with a Micropower charger connected to the MG battery system.
¶ Installation
Always make sure to carefully read and follow the charger manuals first.
¶ AC and DC connections
This type of charger comes with pre-assembled cables.
DC cables:
| Color | Description |
|---|---|
| Blue or Black | DC negative (-) |
| Red | DC positive (+) |
¶ CAN bus connections
Micropower CAN bus connector details
An additional Micropower-M12 adapter cable is needed to connect the Micropower charger to the MG system.
| Type | Length | MG article number |
|---|---|---|
| HD26 - M12 male straight | 2 meter | MGROB0000106 |
MG CAN bus connector details
The M12 connector of the adapter cable is compatible with the standard MG M12 pinout.
For MG CAN bus connector pinout, check the application note: MG CAN bus pinning
- MG Master LV/HV:
The charger must be connected to the Aux. CAN of the MG Master LV/HV. - MG SmartLink MX:
The charger can be controlled on both CAN-A or CAN-B connections of the SmartLink MX.
A MG Energy Monitor or Diagnostic tool will no longer be supported during normal usage if the charger is connected to CAN-B. Settings can then be changed using the MG Connect App (Available for Apple or Android)
Before the connections of the Micropower charger can be accessed, the cover must be removed as followed:

¶ Configuration
The charger can be connected to a Master LV/HV as well as the SmartLink MX. However, the configuration between those is a bit different.
¶ MG Master LV/HV
- Make sure the External CAN bus protocol is set on
MG NMEA2000 - Set the
Charge current limitto the maximum of the chargers in total. - Select the number of installed chargers in the
Number of Micropower chargersfield. - Restart the MG Master LV/HV to activate the settings.
¶ MG SmartLink MX
The SmartLink MX is controlling the connected chargers by CAN bus. The configuration consists of a normal configuration to add the connected Master LV/HV's to the SmartLink MX and a few settings to enable the charger control.
¶ Master LV/HV
Adding a Master LV/HV to the SmartLink MX configuration:
¶ SmartLink MX
- If the charger is connected to CAN-B of the SmartLink MX, the setting CAN-B CAN bus protocol must be set to
Additional charger protocol. Read below info before changing this setting!
This setting must be changed with the MG Connect App (Available for Apple or Android)
Once this setting is changed, a MG Energy Monitor or Diagnostic tool will no longer be supported on this port.
- Set the
Charge current limitto the maximum of the chargers in total.
- Change the setting
