Fronius IG

Highest performance in the smallest space: Fronius IG - The allrounder with special talents.

How long is the warranty for the Fronius IG inverter?
All the inverters from the Fronius IG series with production dates from 01.01.05 onwards have a 5-year warranty.

My inverter is displaying status message “STATE 516”
This code indicates that more than 50 errors occurred on this day. This code appears more often in the winter when the modules are covered in snow and the “POWER LOW” or “DC LOW” error occurs. In this case, detailed information can be found under the “State PS” menu option in Setup. This displays the last error that triggered the “STATE 516” code.
To check the last error to have occurred, simply press “Enter” to acknowledge error 516.
The unit will automatically switch to the “STATE PS” menu, where you can read the last message.

How is the inverter connected?
The terminal area on our units can take the form of screwed connections or plug-in contacts.
Inverters from the Fronius IG series can be ordered with screw terminals and with AC or DC plug-in connectors (MC3, MC4 or Tyco connectors).

Where will I find the serial number on my unit?
There is a sticker with “Ser. No. xxxxxxxxx/xx” on the metal part of the plug-in card on the bottom of the unit. This ten-digit number is the serial number of your inverter.

Can I reset the “TOTAL” value of the unit?
This is not possible and would be equivalent to fraud, just like resetting a car’s odometer.

How can I minimize the length of time the inverter is out of use in the event of a fault?
In such circumstances, you should ideally contact the electrical engineer who installed your system. who can arrange all the necessary further steps in order to eliminate the fault as quickly as possible with the aid of the Fronius Service Hotline.
The Fronius IG 60 and Fronius IG 40 inverters both use the “MIX”-Concept. This means that they are powerful inverters with two power modules that share the work. As well as being more efficient under partial load, this technology also offers greater protection against failure. If one power module fails, the other one continues to work. There is no loss of energy until the irradiance level is high.

What does the “DC LOW” message mean?
This error means that the module's DC voltage is too low. It generally occurs when modules are covered with snow or very dirty. Of course, this message also appears every morning and evening.

What does the “POWER LOW” message mean?
This error means that the module's DC power is currently too low. It generally occurs when modules are covered with snow or very dirty. Of course, this message also appears every morning and evening.

My inverter is displaying the error “State 412”. What does this mean?
This probably indicates a DC voltage in excess of 500V at the unit. Please ask your installation engineer to measure the no-load voltage of the solar modules and check the system design. For safety reasons, always disconnect the inverters from the modules until the situation has been clarified since voltages in excess of 500V DC can damage the Fronius IG.
