The Enphase Microinverter LEDs are blinking red
A red blinking light indicates that the microinverter is not producing power. To identify the issue, follow these steps, Inspect polarity, Check DC voltages: Use a voltmeter to measure the PV module’s Open Circuit Voltage (VOC).
The Enphase Microinverter LEDs are blinking orange
Orange blinking lights indicate that the microinverters are producing power, but not communicating with the Envoy. Is there an Envoy plugged in and operating at the site? If so, what does the Communication Check show? This is likely a communications issue.
The Enphase Microinverter LEDs are not lit
If no lights are visible, it indicates that the microinverter is not receiving power from the PV module. Here are some troubleshooting steps: Consult the manual, Check connections, Inspect adaptors or jumpers, Tyco connectors If Tyco connectors are in use, be cautious, as some models can mate while reversing polarity.
