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
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.
