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 StarInverter itself to ensure only safe operating conditions exist within the 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 StarInverter will illuminate the “STAND BY” (Red) LED.
The “STAND BY” (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 120 volts for the PVP1800 or 180 volts for the
If the “STAND BY” (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 StarInverter Command Center is communicating with the inverter, the exact operating conditions can be determined in
