Jakiper 48v (SOK?) battery BMS is Pace brand and not Seplos type

[Lardino]

I have been playing around with communications for the Jakiper 48v battery I received recently .
The Jakiper supplied software that runs via RS232 port works fine.
But I could never get it to work or any other Seplos type bms software to work on RS485 ports .
I just discovered that it is not a Seplos type bms but one that is made by PACE similar to this one .

Household Energy Storage BMS(100A) - Household Energy - PACE

PACE is specialized in custom lithium battery with smart BMS. The main products are 24v, 36v, 48v, 60v, 72v lithium battery pack with BMS. The application can be AGV, Robot, Motorcycle and so on.

Maybe someone else has info or this will save them barking down the wrong path like I had just done.
I wanted to see if I could get the data out of bms and onto esp8266 so I can send it MQTT to my grafana solar monitoring graphs.
This is a project that I tried - but it is for Seplos.

Yeah good luck getting that RS485 to work... lol

Well Jakiper showed video of data from RS485 going to Growatt inverter so maybe there is hope

you playing with the inverter Protocol but you need the pace protocol

@Lardino want s a monitoring "software" like Seplos Controller

..Lardino says:

The Rs232 is your Port for monitoring , The Seplos has Protocol version 2.0 and your pace has Version 1.0
But its not the same Protocol! the one is seplos ,the other has pace protocol and in different versions!

I spoke only over Monitoring Communication!

The Inverter Commnuication you can set in the bms software!

wow, very good video

what kind of protocol runs on rs485_b and C ?
the bms2bms Protocol (PaCE Protocol) ?

nu clue , ask @LithiumSolar

 

[BavarianSuperGuy]

i found out and for what i need which protocol
then is the rs485b and c for my external wifi monitoring and bms2bms communication!
Now i must shutdown the internet to become the protocol

>shutdown -h now "indaNett"
>cp pdf from pace to bsg
>quit

.iam out

Basically all i want to do is get the cell voltages and other info that the inverter could get. So with setting up the rs485A port then can poll it with modbus like the inverter would do and get the battery data. I don't care to access the full bms and change any settings - just for monitoring. Though I think some of the inverters may have some limited control of the bms ? I don't have a Growatt or MPP type inverter so don't know how they function in regards to bms .

what inverter do you have, and does it have canbus/rs485 ports and does it support pylontech batteries?

 

[Lardino]

I have an Outback 48v so it has no communications to bms .

 

[houseofancients]

wouldnt it be simpler to just add a shunt ?
since your inverter cant communicate anyway, i dont see a point here

 

[Lardino]

I like to monitor my solar system. I have all my solar data going by mqtt to raspberry pi . On the Pi I run Grafana program which allows me to make whatever kind of graphs I want . No reason not to have the battery data in the mix too . I do have shunts on my system - on the Midnite controllers and also a shunt for Peacefair PZEM-017 on a direct DC solar part of the system. Example in photo

 

[sergea]

wow, very good video

the bms2bms Protocol (PaCE Protocol) ?

it is pylontech RS485 protocol, so you akready have a lot of scrip/app available to do it

 

[Lardino]

There is project now to monitor the Jakiper and maybe also SOK - look at this post https://diysolarforum.com/threads/m...k-batteries-via-modbus-to-esp8266-mqtt.45540/

@Lardino, when you mentioned the name PACE I remembered reading about it and found this in my archive. Not sure whether it will be of help.

Thanks deonbez - I will pass that on to Graham .
There has been a lot of progress and we now are able to monitor all interconnected batteries ( and each cell too) in the stack using pylon protocol via the console port. Either an esp32 or raspberry pi can be used . It is all documented here https://github.com/ClassicDIY/PylonToMQTT
Also here is discussion

Monitoring Jakiper ( maybe SOK too?) server rack batteries via modbus to Esp8266 mqtt

I have been trying to monitor Jakiper server rack battery model JK48V100 via RS-485. The RS-485A port is programmable using Jakiper software. You can set it up to work with certain inverters using the Pbms Tools software that Jakiper provides . You need to connect to the RS-232 jack to use the...
