Why does my Fronius Battery Charger turn off while charging?
If your Fronius Battery Charger switches off during charging, it's possible the ambient temperature is too high, activating the overtemperature protection. Allow the device to cool down. Charging should recommence automatically once it has cooled sufficiently; if not, have it checked by a workshop.
How to fix Fronius Selectiva 1020E when ready and error lights are flashing?
If both the ready and error indicators are flashing on your Fronius Battery Charger, there is a mains fault, and the mains voltage is outside the tolerance range. Check the mains conditions.
What to do if the Fronius Selectiva 1020E Battery Charger switches off during charging?
If your Fronius Battery Charger switches off during charging, it could be due to the ambient temperature being too high, which activates the overtemperature protection. Allow the device to cool down. Charging will recommence automatically once the device has cooled sufficiently. If it does not restart, have it checked by a workshop.
Why is the ready indicator lit and the error indicator flashing on my Fronius Battery Charger?
If the ready indicator is lit and the error indicator is flashing on your Fronius Battery Charger, it could be due to a short circuit on the charging plug or charger lead. Check the charger leads, contacts, and battery poles. Another cause might be battery overvoltage or undervoltage. In this case, select the correct charging characteristic/function or set the correct battery voltage.
What to do if the ready indicator is lit, error indicator is flashing, and SOC indicator 1/2/3/4 is flashing on Fronius Selectiva 1020E?
If the ready indicator is lit, the error indicator is flashing, and the SOC indicator 1/2/3/4 is flashing on your Fronius Battery Charger, it could be due to a timeout in the corresponding charging phase or the battery capacity being too high. Select the correct characteristic type according to the enclosed characteristic data sheet and charge again. It could also be caused by a faulty battery (cell short circuit, heavy sulphation), so check the battery and replace it if necessary. Another possible cause is that the optional external temperature sensor has tripped due to over- or undertemperature. Allow the battery to cool, or charge the battery in a more suitable area.
What to do if the ready indicator is flashing and the error indicator is lit on my Fronius Selectiva 1020E Battery Charger?
If the ready indicator is flashing and the error indicator is lit on your Fronius Battery Charger, it indicates a polarity reversal of the charger leads. The reverse polarity protection has tripped. Connect the battery poles correctly.
