4.APsystems Microinverter System Installation
4.3.7 Step 7 - Connect APsystems Microinverters to the PV Modules
Figure 8
If the DC connector is not connected with the PV module,you need to remove the dust
cap,and cover the protection cap.
When plugging in the DC cables, the microinverter should immediately blink green
three times. This will happen as soon as the cables are plugged in and will show that
the microinverter is functioning correctly. This entire check function will start and end
within 5 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.
4.3.8 Step 8 - Complete the APsystems installation map
Fill in the APsystems Registration Cards, which provide system information and the
installation map. Feel free to provide your own layout if a larger or more intricate installation
map is required. The layout map provided is designed to accomodate labels in vertical or
horizontal orientation to meet all the field PV connections.
a. Each APsystems Microinverter has removable serial number labels.
b. Peel labels off, affix one to the respective location on the APsystems installation
map,and fill in 1,2 in the label below,according to the layout on the roof.
c. After the completion of installation drawings sent to APsystems website
