What to do if Fronius IG-TL 3.6 has no internal communication with power stage set?
If your Fronius Inverter shows no internal communication with power stage set, and the status code persists, contact a Fronius-trained service technician.
What to do if Fronius IG-TL 3.6 Inverter shows fixed voltage setting error?
If the 'fixed voltage' setting has been selected instead of MPP voltage operation and the voltage is set to a value that is too low or too high on your Fronius Inverter, remove excess solar modules so DC voltage fits within inverter limits. If the status code persists, contact a Fronius-trained service technician.
How to update Fronius IG-TL 3.6 Inverter power stage set software?
If your Fronius Inverter indicates that the power stage set software is being updated, update the firmware using Fronius Solar.update or a USB stick.
How to fix invalid power stage set configuration on Fronius IG-TL 3.6?
If your Fronius Inverter displays an invalid power stage set configuration, update the inverter firmware. If the status code persists, contact a Fronius-trained service technician.
What to do if Fronius IG-TL 3.6 Guard Control memory is defective?
If your Fronius Inverter indicates that the Guard Control memory is defective, and the status code persists, contact a Fronius-trained service technician.
What does solar module ground insulation error mean on Fronius Inverter?
If your Fronius Inverter indicates a solar module ground, insulation error (connection between solar module and ground), and the status code persists, contact a Fronius-trained service technician.
