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 FLASHING

Inverter 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

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.
