In the core this was caused by the same problem: the integration receives an answer to another query than the one it made, resulting in wrong values being processed. It is not possible for me to detect that his has happened.

Hopefully this is a bug in the modbus-library that I’m using: I will be upgrading to the latest pyModbus version from the moment https://github.com/riptideio/pymodbus/issues/1146 has been resolved. However, I can’t give any guarantees that this will fix the problem.

In case I receive wrong values, I now do a retry. This can cause timeouts if you’re trying to read too fast from the inverter, as the update-requests come too fast and the modbus-interface gets clogged up.
