4.0 TROUBLESHOOTING

If the StarInverter’s “STAND BY” LED remains solid red or blinking red for a prolonged period (more than 24 hours), the AC breaker or AC disconnect should be turned to the OFF position for 1 minute and then returned to the ON position. After reset, if both AC and DC operational specifications are met, the red LED is OFF and the green LED is illuminated. If after AC is reset the red “STAND BY” light remains illuminated or blinking, double-check all connections and voltage levels. If the red “STAND BY” light is still illuminated or blinking, contact your authorized dealer/distributor for product support.

The LEDs will display the following light indicators when a fault has occurred:

RED FLASHINGInverter has a fault, refer to fault codes below for diagnosis

GREEN SOLID, RED FLASHING Inverter has faulted, operational DC range is present.

 

AC/grid-related fault

RED SOLID

DC Limit is too low; inverter is in “STAND BY” mode.

In addition to the above fault indicators, the PVP Command Center software will indicate system status. If a fault has occurred, a fault message as well as the corresponding code will be displayed.

The vacuum fluorescent display will provide the following codes when a fault has occurred:

First Code:

 

 

PDPA FAULT

0x8000

power module generated fault

VOLTAGE FAULT

0x1000

Code 3 will contain further information

GROUND FAULT

0x0400

 

LOW POWER FAULT

0x0200

array power too low for max power

 

 

tracking

CPU LOAD FAULT

0x0100

software overload

OVERCURRENT FAULT

0x0040

 

PRECHARGE FAULT

0x0020

 

HEATSINK TEMP FAULT

0x0004

 

AMBIENT TEMP FAULT

0x0001

 

Second Code:

0x0000

will always remain zero

Third Code: (Voltage Faults)

 

 

AC SENSE

0x0800

AC voltage sensing missing per UL or

 

 

Ground Fault

AC OVER VOLTAGE FAULT

0x0400

 

AC UNDER VOLTAGE FAULT

0x0200

 

AC UNDER FREQENCY FAULT

0x0100

 

AC OVER FREQUENCY FAULT

0x0080

 

DC UNDER VOLTAGE FAULT

0x0020

array voltage too low

DC OVER VOLTAGE FAULT

0x0010

 

P15 FAULT

0x0002

+15V supply out of specifications

PS FAULT

0x0001

+5V supply out of specifications

As indicated above, there are three 16-bit codes assigned to describe faults, one of which will always remain zero. More than one fault can be represented at a time. This will be indicated by a fault with a code equal to the sum of the individual faults.
