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.

Fronius STATE codes beginning with 3xx
Fronius Primo STATE codes beginning with 3 are status codes that may occur while feeding energy into the grid, but generally do not cause the process to be interrupted for any length of time.
The inverter disconnects automatically from the grid, the grid is then monitored as specified and the inverter attempts to resume feeding energy into the grid.

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.

Sharp JH1600 fault codes beginning with E or d are error states that are more serious.
These errors always start as E codes but when the fault continues it will change to a d code.
They are either temporary or lasting faults and are triggered by faulty hardware or a software problem.
Try switching off the inverter following the system shutdown procedure, leave off for a few minutes then attempt to restart.
If the fault continues please contact Swift Solar Repairs for further assistance.

Description |
Remedy |
---|---|---|
Derating |
Over temperature |
Derating refers to overheating and will often require a replacement inverter if outside of warranty, or a repair if within warranty. |
Disturbance |
No grid connection |
Check the AC isolator below the inverter and the switch labelled “AC solar supply” in the switch board. The inverter may need replacing. |
Error |
Internal Fault |
Error codes represent an internal error and will likely need to proceed with a warranty claim or, if out of warranty, a replacement inverter will be reuired. |
Grid Mon |
Grid Monitoring |
This message will appear during start up and shut down. If it occurs when the sun is shining, the inverter may need replacing. |
MPP |
MPP Mode on |
This is not an error and the inverter should still operate with this fault being displayed. |
Off Grid |
System Islanding |
The inverter will need to be replaced. |
Offset |
Measurement |
This code does not indicate a fault. |
Riso |
Insulation Resistance |
A Swift Solar Repairs technician will need to attend to test the solar panels for earth leakage. |
Stop |
Interruption of operation |
Check the solar supply main switch. The inverter may need replacing. |
V-Const |
Constant voltage operation |
This code does not indicate a fault. |
Waiting |
Switch on conditions not met |
This code does not indicate a fault. |
vac-BFR |
GRID ISSUE |
Check the solar supply main switch. The inverter may need to be replaced. |
Varistor Failure |
|
A varistor failure is generally caused by grid surge and is not covered by warranty. The inverter may need to be replaced. |
