3.2  LED Indicator Lights/Vacuum Fluorescent Display 
3.2.a LED Indicator Lights (Model PVP1100) 
The StarInverter PVP1100 displays 7 LED indicator lights visible through the upper left 
corner of the front panel. Refer to Figure 20. 
These lights will indicate the PVP1100’s status and real-time output power into the AC 
Grid. 
If the PVP1100’s operating environment is safe to produce power into the AC grid, the 
“OK” (Green) LED is illuminated. 
If at any moment the operating environment moves outside the safe operating limits, 
governed by UL 1741, IEEE 519, and NEC 690, the “FAULT” (Red) LED indicator will be 
illuminated. 
The StarInverter is continuously monitoring
: 
1.  The AC grid connection to ensure the AC voltage and frequency levels are within 
safe operating limits (per UL and NEC specifications). 
2.  The DC PV panel input(s) to ensure safe operating conditions (per UL and NEC 
specifications). 
3.  The PVP1100 itself to ensure only safe operating conditions exist within the 
PVP1100’s operating environment. 
If all 3 conditions are met the inverter will illuminate the “OK” (Green) LED. 
If any one of the operating conditions is not met there is a fault and the PVP1100 will 
illuminate the “FAULT” (Red) LED. 
The “FAULT” (Red) LED will illuminate when the PV panel voltage is not within safe 
operating limits. This will occur at sunset, when the inverter will turn off for the night. It 
may also occur when clouds reduce the amount of sunlight, or when the panels are 
covered with snow. Anytime the level of sunlight is too low to produce 90 volts of DC 
input (the low end of the PVP1100’s operating range) the inverter will turn off. This 
ensures only safe and clean (low distortion) power is being generated. When the panels 
are once again exposed to enough sunlight, the PVP1100’s auto-start feature will begin, 
and after 5 minutes, the “OK “ (Green) LED should illuminate. 
If the “FAULT” (Red) LED continues to illuminate when there is sufficient sunlight for 
operation, verify all wiring connections are solid. See Section 4.0 Troubleshooting. If the 
PVP1100 Command Center is communicating with the inverter, the exact operating 
conditions can be determined in real-time.
