Low output voltage |
| You are using a voltmeter that cannot | Use a true RMS reading voltmeter such as the Fluke 87. |
| |
(96 volts |

|
|
|
mode. |
| modified sine wave. |
|
|
|

|
|
|
| |
No output voltage. The status LED is red. |
| AC shore power is not available or out of | operating range and the inverter has shut down with the display |
| |
|
| screen showing one of the following error codes: |
| ||
|
|
|
|
| |
|
| • Low input voltage (fault code ) | • Check the DC connections and the cable. |
| |
|
|
| • | Recharge the battery. |
|
|
|
|
|
| |
|
| • High input voltage (fault code ) | • Verify the unit is connected to a 12V battery. |
| |
|
|
| • Check the voltage regulation of the external charging system |
| |
|
|
|
| (if any). |
|
|
|
|
|
| |
|
| • Unit overload or AC output short | • Reduce the load. Make sure the load does not exceed the |
| |
|
| circuit (fault code ) |
| output rating. |
|
|
|
|
|
| |
|
| • Thermal shutdown (fault code ) | • Allow the unit to cool off. |
| |
|
|
| • Reduce the load if continuous operation is required. |
| |
|
|
| • Improve ventilation. Make sure the inverter’s ventilation |
| |
|
|
|
| openings are not blocked. |
|
|
|
|
|
| |
|
| • AC transfer relay has overheated | • Improve ventilation. Make sure the inverter’s ventilation |

| grille is not blocked. |
|
|
|
| • | Reduce the load. |
