4.APsystems Microinverter System Installation
4.3.7 Step 7 - Connect APsystems Microinverters to the PV Modules
Figure 9
When plugging in the DC cables, the microinverter should immediately blink red one
time and 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.
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.
Each channel connects 2 PV
modules in series (For PV
modules with Voc<60V).
The input channel will not
work if connects to a single
module(Voc<60V).
That means the quantity of PV
modules in the sysem is even
number.
