Fronius · Perfect Charging
The nominal voltage of the battery, as read from its TagID module, is not supported by the battery charger, or a specific charger setting prevents its use. This means the charger cannot safely or effectively charge the battery due to voltage mismatch.
Click steps to track your progress.
Verify the battery's actual nominal voltage by checking its nameplate or specifications.
Check the charger's settings related to supported battery voltages and adjust the voltage range or charging profile if necessary.
Inspect the TagID data for correct nominal voltage programming and ensure it corresponds to the physical battery.
