function will start and end within 10 seconds of plugging in the unit, so pay careful attention to these lights when
connecting the DC cables.
WARNING: 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.
WARNING: Each PV panel must be carefully connected to the same channel.
Make sure to not split positive and negative DC cables into two different input channels: microinverter will be damaged
