QS1-LK Microinverter Quick Installation Guide

The sketch of QS1 support system.

All the PV modules are placed into two lines. Then put a QS1 in the middle of the two lines and make

sure it is easy to connect with four PV modules which are next to it, as well all the cables.

Step 1. Verify the grid voltage to match with microinverter rating

Step 2. The AC bus distribution

a. The AC bus is arranged at the proper position of the microinverter.

b. One end of the AC bus access junction box into power grid.

c. Wire the conductors of the AC bus: L - BROWN; N - BLUE.

NOTE: Wiring colour code can be different according local regulation, check all the wires of the

installation before connecting to the AC bus to be sure they match.Wrong cabling can damage

irreparably the microinverters, such an issue is not covered by the warranty.

Step 3. Attach the APsystems Microinverters to the racking

NOTE: Do not place the microinverters (including DC and AC connectors) where exposed to the

sun, rain or snow, even gap between modules. Allow a minimum of 3/4’’(1.5cm.) between the roof

and the bottom of the microinverter to allow proper air flow.The racking of install microinverter

must be reliably grounding.

d. Mark the location of the microinverter on the rack, with respect to the PV module

junction box or any other obstructions.

e. Mount one microinverter at each of these locations using hardware recommended

by your module racking vendor.when install microinverter, grounding washer

Must be facing the racking.

Step 4. Ground the system.

Step 6. Install a Bus Cable End Cap at the end of AC bus cable.

a. Strip cable jacket. c. Insert the wires into the cable clamps.

b. Insert the cable end into the seal. d. Rotate the nut with 3.3N·m until the

latching mechanism meets the base.

Step 7. Place the PV modules and connect each QS1 to the PV modules

Step 8. Complete the APsystems installation map

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. The other one serial number label, posted on the solar module frame is easy to view the

position.

d. After the completion of installation drawings sent to APsystems website.

www.APsystems.com.

NOTE: Sequence of steps 1~8 can change for convenience of installation.

NOTE: Using APsystems' mobile app ArrayApp can make the installation and registration much

more simple.

Step 9. Start the operation

1. Turn on the AC circuit breaker on each microinverter AC branch circuit.

2. Turn on the main utility-grid AC circuit breaker. Your system will start producing.

power after a two-minute waiting time.
