Breaking change
The unit of 'pv_system_trannergy_inverter Hours Total' (sensor.pv_system_trannergy_inverter_hours_total) changed to 'h' which can't be converted to the previously stored unit, 'Hours'.
If the historic statistic values have a wrong unit, you can update the units of the old values.
Otherwise you can choose to delete all historic statistic values, and start over.
