Detected inverter errors cause the red ERROR LED to illuminate. These menu items help determine the cause of error conditions.
These menu items normally display “NO” for all menu items in which no error is detected. The display changes to “YES” for menu items where errors were detected.
Note: All errors except “05A Overcurrent”, “05F External Err (Stacked)”, and “05G Input Relay Failure” will allow the external AC source (if within acceptable tolerances) to
If “Yes” is displayed, the AC output wiring of the inverter is short- circuited or has had an excessive load connected for too long.
To clear this fault, disconnect the loads and restart the inverter by pressing the red INV ON/OFF MENU button to directly access the 01A Inverter menu item and select OFF, then ON or SRCH. Reconnect the loads (one at a time) to find the load, or combination of loads, causing the problem.
Note: An
0 B Transfo mer Overtemp
If “yes” is visible in this display, the transformers have exceeded their designed operating temperature and the inverter will shut off.
If the unit is operating as a battery charger when this error condition occurs, the inverter stops charging to prevent further overheating.
In the inverter mode, overheating can be caused by:
05BTransformer | • powering an excessive load for too long, |
• blocked air vents or a fan failure, and/or | |
• insufficient circulation that allows the exhaust from the unit to be | |
drawn back into the unit. | |
When the inverter has this error condition, AC current from the source | |
(utility grid or generator) is passed through the inverter to power the | |
loads. Power management features provided by the inverter are not | |
available with this error. | |
The inverter automatically resets when it has cooled. | |
