Can you connect a Seplos BMS 48V 100A 16s directly to a Cerbo GX?

Hello!

I am trying to connect my new 48V battery to the Cerbo GX to see the state of charge in my Victron touch. I did the can connections following both manuals, and I have tested the terminals.

CAN-L

CAN-H

CERBO GX

SEPLOS BMS

I see 2.5V in both can H and can L terminals, any idea of why I am not receiving any datas in my Cerbo GX?

First of all, Seplos is not officially supported, see the battery compatibility list for currently supported brands:
https://www.victronenergy.com/live/battery_compatibility:start

However, this thread has some information which might be useful to you:

@GinesVadillo

I use a original Victron VE.Can to CAN-bus BMS type B Cable

Works perfectly, make sure that the BMS which is connected to the Cerbo has ALL DIP switches on OFF

Hi @Gregor, i'm curious about the model for your seplos BMS and the selected Canbus protocol?

as mine (selecting Vic / sma protocol) didn't report cell voltage neither temperature

Hi @Gregor and thank you for your feedback

we do have obviously different product as yours is recognized as "LBSA SmartBMS" and tagged as BMS100310B, when mine is signaled by Cerbo as "SHEnergy" and as part model 1101-SP16 from Battery Monitor 2.1.8

I will anyhow ask Seplos if there is a firmware update for my hardware

@jeanmarie I do not know how many different BMS Seplos has but the BMS records to the Cerbo has changed every time when I updated the firmware from "LG Resu" to "!" to "SHEnergy" and now it shows "LBSA SmartBMS"

the nHW i have is:

@Gregor , Yes it's almost the same than mine (I have 200A models).


I also had "LG REsu" in the Cerbo interface, but it was with the default CAN protocol selected from Seplos BatteryMonitor software which was pylontech.

After selecting the right protocol (Victron) and uploading it to all my batteries they change their recognized name to SHEnergy and I got the confirmation by my Seplos contact that this was the right procedure.

Have you ever selected and downloaded any protocol from BatteryMonitor to your battery ?

@jeanmarie I have already updated the CAN firmware 3 times. Using the Seplos SW to upload the xx.ehex file to the BMS and then of course select the right CAN protocol in the top right corner. The latest Vicron Version that works for me (finally) fine is the 2.8

The CAN firmware file:

CAN1101[FW28-DFSET_VC03_210916](定制victron&SMA).ehex

The best is to contact your dealer who should able to provide this kind of file to you.

Worst case : try to contact Seplos on their homepage

I don't think Victron, by making this community forum, ever intend to become a new shared files host.
