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.
What to do if the Fronius IG-TL 3.6 Inverter display fails completely?
If the Fronius Inverter display is completely blank, there might be an issue with the photovoltaic system if the open circuit voltage is less than 350 V. If the open circuit voltage is greater than 350 V, this may indicate a basic fault in the inverter, so notify a Fronius-trained service technician. Also, ensure the AC voltage at the inverter's connections is 230 V (+ 10 % / - 15 %).
What to do if Fronius IG-TL 3.6 Inverter DC input voltage is too high?
If your Fronius Inverter shows that the DC input voltage is too high, the fault should rectify automatically. If this status code keeps recurring, contact your system installer.
What to do if Fronius IG-TL 3.6 interior temperature is too high?
If your Fronius Inverter indicates that the interior temperature is too high, you can clean the cool air vents and cooling elements with compressed air, if required. The fault should rectify automatically. If this status code keeps recurring, contact your system installer.
What to do for over-temperature cooling element on Fronius IG-TL 3.6 Inverter?
If your Fronius Inverter displays an over-temperature warning for the cooling element, the fault should rectify automatically. If this status code keeps recurring, contact your system installer.
What to do if Fronius IG-TL 3.6 RCMU detects a fault current?
If the RCMU in your Fronius Inverter detects a fault current, check the grid connections or fuses. If this status code continues to appear, contact your system installer.
What to do if Fronius Inverter shows no AC grid detected?
If your Fronius Inverter isn't detecting an AC grid, begin by checking the grid connections. If the status code continues to appear, it's best to contact your system installer for assistance.
What to do if Fronius IG-TL 3.6 Inverter AC frequency is too low?
If the AC frequency of your Fronius Inverter is too low, check the grid connections. If the issue continues, contact your system installer.
What to do if Fronius IG-TL 3.6 Inverter AC frequency is too high?
If your Fronius Inverter shows that the AC frequency is too high, you should check the grid connections. If the status code keeps recurring, contact your system installer.
What to do if Fronius IG-TL 3.6 Inverter AC voltage is too low?
If your Fronius Inverter displays a message indicating the AC voltage is too low, start by inspecting the grid connections. If the problem persists, contact your system installer.
