Hi, I am busy trying to communicate with Huawei ESM-48100B1 batteries through RS485. When polling just one battery I have no issues, but I want to connect more batteries in parallel and read them as a rack. When I procured my batteries they were set to the default slave ID of 214 so they both share the same ID. Looking through the modbus spec it gives no indication of how multiple batteries can be read from or how slave IDs can be changed. I know there is a Smart Logger that Huawei sells that allows one to edit certain parameters on these batteries (haven't been able to confirm if Slave ID is one of them), but I would prefer a method that didnt require me to go out and buy another piece of equipment. Does anyone have any experience working with Huawei batteries?

Can a moderator please remove?

@BritishRacingGreen Thanks for the info! I am using an OG5.48 series Kodak Inverter. Tried to look to see if I could find the model year to compare with the mks3, but cannot find any info about which preceded which.

Hi, I am new to the forum was hoping someone could help me find the pinouts for CAN communication for Kodak's Solar Off Grid Inverter. The manual mentions a custom made RJ45 cable, but has no indication of what the pinouts should be. Investigating on this site I found users that helpfully shared the pinouts for RS485 communication (Being pins 3 and 5 apparently), but I just need the CAN bus pinouts so that I can log data from the Inverter. Can anybody help?
