Before upgrading from 0.4.x I strongly suggest you remove the current Integration from the Integration page before upgrading!
When you re add the Integration following the code upgrade, if you name the Integration the same you shouldn't affect any sensor names or automations other than the mentioned name changes.
If the Integration fails to load with the following error in your log "unrecognized inverter type - serial number : {your_serial_number_here}" Please see #26 providing the details asked for.
Added the following Inverters:
Gen3 X1 3.7kW serial starting XRE3 (Should also work for 3.0kW)
Gen3 X3 serial starting H3DE or H3PE
Gen4 X1 7.5kW serial starting with H475
Untested:
Gen4 X1 6kW serial starting with H460 (I am assuming this based on the naming of the Gen4 X1 5kW & Gen4 X1 7.5kW)
X3 MIC 10kW based on serial starting MC10 this might still fail with "unrecognized inverter type - serial number : {your_serial_number_here}" as I believe the MIC Pro has the registers at a different location compared to the GenX Inverters.
