iBMS: JK BMS CAN bus comms now possible for inverters that support Goodwe and Pylontech batteries

This might be a silly question, but can I connect two JK-BMSs via BLE to a single ESP32? Or, does the Deye-6K support two batteries? I will have two 16S batteries with different capacities, each with a JK-BMS on it, in parallel. I mean, even if the ESP32 sends a single capacity value (the average or something), I am fine with that, though I'm sure there are better ways to handle this. Though an important value for me would be the sum of battery currents.
I’m using two JKs over BLE along with a Victron shunt to a single Atom S3 ESPwith CAN connector. Using the updated version of code from the YAMBMS thread. It takes capacity and other information from each BMS.

 
Hi,
My boards don't use BLE, they use Serial via the GPS port as it is more reliable.
I have a Multi-BMS solution (one board per BMS) that combines all the data and sends it to the inverter, most inverters will only accept one CAN data stream, so it has to be combined.
Regards
Combined data looks like:

Yes it's possible with YamBMS.

Max 2x BMS BLE on an ESP32 and 3x BMS BLE on an AtomS3.
 
Writing your own software in ESP-IDF and designing and manufacturing hardware in small volume does not come cheap.
Let alone supporting the software, hardware and the customer.
I'm not getting rich anytime soon, it barely covers the costs.
 
Im trying to connect two 16s batteries each with a JK BMS B2A20S20P, and get them to talk to my PowMr POW-SunSmart 12KL3 inverter


Does the product promoted in this thread help me achieve this?

Hi,

Yes it will allows the connection of up to 10 BMS to one inverter.

You would need 1 x iBMS Isolated Multi board, and 4 pin cable per JK-BMS.

Awesome. I was just watching a video from the "off grid garage" talking about one of your products. Coincidentally it turns out im also in Brisbane haha.

Do you want to DM purchase instructions? not sure what we can an cant say in these threads.
