Modbus not working after KH9 firmware update to 1.39 1.01 .35

Hi!

Just got my KH9 inverter updated by Fox to Master 1.39, Slave 1.01, ARM 1.35

After the update Modbus is no longer working, I'm getting from connection:

Error reading registers. Type: RegisterType.HOLDING; start: 31000; count: 55; slave: 247 from tcp://XXX.XXX.XX.116:502: Exception Response(131, 3, IllegalAddress)

Maybe an already known issue?

Thanks!

The latest KH firmware changes the register mapping from previous firmware releases which breaks the integration - if you follow this thread #678 (comment) , someone has setup a fork of the repository and tested it on their KH - that will get you up and running in the meantime.
