Fronius Class 1 State Error Codes
Fronius Class 1 state Error codes generally only arise momentarily and are caused by the public grid.
Example: The grid frequency is too high and the inverter may not feed any energy into the grid owing to a standard. There is nothing wrong with the device. The initial response of the inverter is to disconnect itself from the grid. The grid is subsequently checked during the stipulated monitoring period. If no further problem has been detected by the end of this period, then the inverter will resume feeding energy into the grid. The GPIS SoftStart function is activated according to the country setup: After cutting out due to an AC error, the output power of the inverter is continuously increased in line with the national guidelines.
|STATE 102||AC voltage too high||Following careful testing and when the grid conditions are within the permissible range again, the inverter will resume feeding energy into the grid.||Check grid connections: If this STATE code keeps recurring contact your solar power system installer.|
|STATE 103||AC voltage too low|
|STATE 105||AC frequency too high|
|STATE 106||AC frequency too low|
|STATE 107||AC grid outside the permissible limits|
|STATE 108||Stand-alone operation detected|
|STATE 112||RCMU error|
