ReadInputRegisters: Invalid FC 132 with Sungrow inverter

[mlankenau]

Describe the bug
For a week my IOBroker instance is sometimes failing to receive the data from my sungrow inverter and logging "Invalid FC 132 with Sungrow inverter"

To Reproduce
Steps to reproduce the behavior:
1.) Setup Modbus for the sugrow inverter as described above
2.) wait for the errors

Expected behavior
No errors, steady stream of measurements

Screenshots & Logfiles

I receive:

2024-03-14 09:30:48.520	error	Client in error state.

2024-03-14 09:29:44.293	warn	Poll error count: 1 code: "ReadInputRegisters: Invalid FC 132"

My Register setup:

My general setup:

Versions:

• Adapter version: 6.1.0 and 6.0.0
• JS-Controller version: 4.0.23
• Node version: v16.18.1
• Operating system: docker-image: buanet/iobroker on Ubuntu

Additional context

It is not allways happening. If I restart the adapter it works for 30/60minuntes, then the errors start, but I sometime still get updates.

Well, since last update I'm having the same issue. Will try to downgrade the JS-Contr. for verification.
