Connecting the Sucret Sun SLSIFP48100A battery to the Victron Multiplus-II GX via CAN bus

Good afternoon, dear friends, greetings from Ukraine, I purchased a Victron Multiplus-II GX and a Sucret Sun SLSIFP48100A LiFePO4 battery, please help me connect it via the CAN bus, the battery has two RS485 ports, the Victron Multiplus-II GX has two BMS Can and two VE.Can and two 120Ω resistors (terminators) Victron included. In which connectors, what to connect? Battery to one BMS Can and plug to the second BMS Can. In this case, VE.Can remain free. And the pinout of the cable according to type A? Thank you for your understanding, Merry Christmas to everyone.

The battery is not on the victron compatibility list, however that doesnt mean it wont work

But you can not connect rs485 to a can port, doesnt the battery have other ports? (no can?)

Maybe its possible to use a victron rs485 to usb converter, but im not sure it will work…

seasons greetings!


This won’t work over CAN, and Dbus serial battery interface won’t work with a modbus protocol.
depends if you have any further information from the battery manufacturer…
If there are relay outputs for over charge and under voltage those can be interfaced with the inverter using the 2 signal BMS extension.

Thank you, have a nice day, sorry for the trouble

Sincerely, Victor

No problem Victor, sorry that I can’t help you with making that work.
