4. APsystems Microinverter System Installation
4.3.7 Step 7 - Connect APsystems Microinverters to the PV Modules
Figure 8
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 show that the microinverter is functioning
correctly. This entire check 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.
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.
Figure 9
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 and warranty will not apply.
