Figure 9
When connecting the 1st module, the LED of the microinverter must flash three times in
green. This happens as soon as the cables are plugged in, to show that the microinverter
is working properly. This control function starts and ends within 5 seconds after the
device is connected, so pay particular attention to these LEDs when connecting the DC
cables.
Double check to make sure all of the AC and DC wiring has been correctly installed.
Ensure that none of the AC and/or DC wires are pinched or damaged. Make sure that all
of the junction boxes are properly closed.
