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.

Black-colored panels on the Enphase app indicate that no power is being produced. This typically suggests that the microinverters are not communicating with the gateway. Communication outages may be caused by poor power line communications, or they may be caused by DC voltage that has slipped below the level required to turn on the inverter. Inverters that are not powered on will not communicate with the Envoy. Check Enlighten or use the Envoy interface to see if the affected inverter shows an event.
