4.3.7 Step 7 - Connecting APsystems microinverters to the PV modules
When plugging in the DC cables, the microinverter should immediately blink green ten times. This will
happen as soon as the DC cables are plugged in and will indicate that the microinverter is functioning
correctly. This entire check function will start and end within 10 seconds of plugging in the unit.
Therefore, pay close attention to these lights while connecting the DC cables.
Double-check to ensure that all AC and DC wiring has been correctly installed. Verify that none of the
AC and/or DC wires are pinched or damaged. Confirm that all junction boxes are properly closed.
Each PV panel must be meticulously connected to the same channel. Do not split positive and negative
DC cables into two different input channels, as this will damage the microinverter and void the
warranty.
