yes,
but u have some problems
u want an hv setup, the GND of jkbms 1 can not be same with jkbms 2 that why u need to take data thrue rs485 or can, usuly for hv setup use jk balancer with can port and u can cascade them , jk bms can not be cascade.
so, better use one jkbms + 2 jk balancer? As I understand, only 24s will be under switch control of jkbms, rest i need have external switch - maybe related to jkbms. jk balancers will be connected to jkbms by cam, and all information about whole set will be from jkbms.

to cut the pack from the invertor u have external switch.
some invertor dont need to send amp readings from bms and u can use only jk balancers for ur pack, some need amp reading from bms and in this case u need a curent sensor. I use an JKbms only for the current sensor , but in the end i will find a better option for that sensor because i am not 100% satisfy.

Very nice work !!, I am struggeling to get my setup working. I have a DIY 16S 48V Battery with a DALY BMS which does both RS485 & CANBUS; it can emulate different CAN setups. My inverter is a NEDAP / Solar Frontier Power Storage ; which also has a CAN bus (got a few of them, hence my desire to get them to work
) , but will only work with the following batteries / BMS:LG Chem
RESU 5.0
RESU 6.4
Akasol
neeoQube
neeoRack
Sony
Olivine ESS
BMZ
ESS 7.0
Saft
Intensium Home
From your list above, I see that the required batteries / BMS above are not supported ? Or would the LG CHEM RESU 5.0 be same as LG RESU LV ?
From somebody else whom sniffed the CAN port on the inverter, please see the telegrams the inverter requests over and over ;
Also indexes are requested

If u hae some esp32 and can tranciver i can programe some "fake" data protocol to test on ur inverter

Thanks for your reply, I do have a bunch of Rasp Pi's and Uno's but ESP32 is new to me. Will order the parts you listed and build the setup and let you know once I have got in all in place and connected. Thanks for the help.

Hi Constantin,
I can't get the ESP 32 into the WiFi in a stable manner. One time it works, then it doesn't work again. After installing the software, JK-71f23a08 appears on the mobile phone WiFi.
I log in, the JKBMS mask appears, I open Configure WIFI.
I mark the home network, then it appears in SSID. I insert the password of the home network, then Safe. Now the WiFi overview of the Hany appears
and briefly an ESP... WiFi network.
this disappears after 30 seconds.
how do I get into JKBMS after that??
Was everything correct up to this point?

Esp will close ap after connecting on local network
Now the esp have one ip from ur local network signed by ur router.
1 - U can discover the ip by scanning ur local network for example with IpScanner app.
2 - U can serial connect to esp with USB cable Com port speed is 115200. Reset the esp and when connect ip will be displayed.
After u know ur esp ip from local network just connect on it in ur browser.

Hi, parts arrived, put them on my breadboard, uploaded the bin files to the ESP32, connected to Wifi (the key is the digits behind JK-), connected to home network, works, get into the MMI. My chip ID is 9629e748 would be great to receive a code. Using my very much vintage scope
, I found that pin 1,2,3 & 7 have some kind of signal on them coming from RJ45 CAN bus on the inverter. I tried all combinations of the these wires on the CAN_H and CAN_L port, hoping to see some kind of data in the app, but that did not happen. Hope you can help me further in next steps ! Thanks in advance.Attachments

Hi Constantin, not sure you saw my reply below, got the setup working. Would be great if you would be willing to help me with this fake data you described. Thanks in advance!

was bussy this days,
give me ur fake data u want to encode in can protocol
Battery Voltage
Charge Voltage
Charge Amps
Discharge Voltage
Discharge Amps
Temperature
this are main data for all bms

Hi Constantin, thanks for your reply. The data would be given I have a 16S Lifepo4 with 80Ah @ 51.2 nominal volt, the BMS @ 100A and the inverter does 75A @ 48 volt. Like with all things I like to keep, do not want to stress more than 80% / 90% hence:
Battery Voltage: 51.2 volt (3.2 per cell)
Charge Voltage: 57.6 volt (3.6 per cell)
Charge Amps: 60 A (75A x 80%)
Discharge Voltage: 45 volt (2.5 / 0.9) x 16
Discharge Amps: 60 A (75A x 80%)
Temperature: 45 Celsius.
Hope this is correct. As I wrote, I have not been able to verify the correct connection between the inverter and the ESP canbus. I was able to identify the pins with signal coming out of the inverter.
Thanks, Marcel

Very nice work !!, I try to test it on a Sunt inverter

Found a nifty device called “USB Tin” on Amazon, which comes with a win app “USB Tin Viewer” which allows me to view data coming out of the inverter, confirming its pin 2-CanH, pin 3-CanL and 4-GND, so that part is also resolved. Still see nothing in the info part of the app, when connected like that, but could also be because key is missing; chip ID is 9629e748 I do see the ESP sending data on the CAN so confirm that also works. Awaiting further instruction. Thks Marcel
