How do I find the Service/Admin Password for my Fronius Inverter?
If you are attempting to update any settings in your Fronius inverter and are required to enter a Service or Admin Password, please reach out to us at
Please quote your inverter model and serial number when you reach out.
If you haven't yet created your account in the Voltello App, or connected your LinkZB or LinkPro, please quote your order number (this will be in your order confirmation email when you bought the Link device) so we can verify your details.
