To Next PageTo Next PageWhy does my Fronius Inverter show Class 1 Status Codes (102, 103, 105, 106, 107, 108, 112)?
Class 1 status codes on your Fronius Inverter typically indicate an issue with the grid. The inverter will automatically disconnect from the grid and monitor it for a set period. If the grid returns to normal within that period, the inverter will resume operation and begin feeding energy back into the grid.
What to do if Fronius Primo 10.0-1 208-240 Inverter displays Class 2 Status Codes (212, 213, 222, 223)?
If your Fronius Inverter is showing Class 2 status codes, check the grid connections. If the status code continues to appear, it is recommended to contact your system installer for assistance.
What should I do if my Fronius Primo 10.0-1 208-240 Inverter is showing Class 3 Status Codes (301, 302, 303, 304, 306, 307, 308, 309)?
If your Fronius Inverter displays Class 3 status codes, and the issue persists, it's recommended to contact a Fronius-trained service technician. If the status code keeps recurring, contact your system installer.
What to do if Fronius Primo 10.0-1 208-240 Inverter displays Class 5 Status Codes (502, 509, 515, 516)?
If your Fronius Inverter is showing Class 5 status codes and the issue persists, it's recommended to contact a Fronius-trained service technician. If this status code keeps recurring, you may also need to contact your system installer.
How to troubleshoot Class 7 Status Codes (705, 721, 731, 732, 733, 734, 735, 736, 738, 743, 745, 751, 752, 757, 758, 766) on Fronius Inverter?
If your Fronius Inverter displays Class 7 status codes, and the issue persists, it's recommended to contact a Fronius-trained service technician.
How to fix a total failure of the display on Fronius Inverter?
To address a total display failure on your Fronius Inverter, check the AC voltage at the inverter's connections. The AC voltage should be between 208–240 V (+10% / -12%) according to the grid requirements.
