Fronius Error Codes

Fronius STATE codes beginning with 1 usually only occur momentarily and are caused by the power from the street (the grid) being outside the inverters operating parameters.

The Fronius inverter reacts by disconnecting from the grid and attempts to switch on again after the specified mains monitoring period, as long as no further errors occur during this period.

The STATE code is displayed whilst the grid is being checked.

Sharp JH1600 Inverter Fault Codes Beginning with F-

Sharp JH1600 inverter fault codes beginning with F are caused by the power from the street (the grid) being outside the inverters operating parameters.

The Sharp JH1600 inverter reacts by disconnecting from the grid and attempts to switch on again after the specified mains monitoring period, as long as no further errors occur during this period.

When the grid conditions are again within the inverters operating parameters the inverter should reconnect to the grid and continue operation unless it has failed.
