APsystems YC1000-3-220 Microinverter Quick Installation Guide

The sketch of YC1000-3-220 support system.

All the solar panels are placed into two lines. Then put a YC1000-3-220 in the middle of the two lines and

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

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

Step 2. Lay the AC bus according to the arrangement of APsystems Microinverter.

Step 3. Attach the APsystems Microinverters to the racking.

Step 4. Attach the antenna to the microinverter, and keep the antenna vertical to the

earth.

Step 5. Connect the APsystems Microinverter cables to the AC bus cable.

NOTE: AC connector interface as follows, NOTE: Cover all unused T connectors with

from left to right PE, N, L3, L2, L1. sealing caps to protect the T connectors.

Step 6. Place the PV modules and connect each YC1000 to four PV modules close-by.

CH4 CH3 CH2 CH1

Step 7. Install a protective end cap at the end of AC bus cable.

a．Wire stripping

b．Insert the cable end into the gasket clamp.

c．Insert five wires into five cable clamps.

d．Rotate the nut with 2.5N·m until the latching

mechanism meets the base.

Step 8. Install the AC branch circuit junction box.

Step 9. Connect the cables to the branch junction box.

a. Put the unused end of the AC interconnector cable into the branch junction box.

b. Place cable connecting to the point of load interconnection into the branch junction box.

c. Wire the conductors of the AC bus: BROWN-L1; BLACK -L2; GRAY-L3; LIGHT BLUE-N;

YELLOW GREEN-PE.

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 10. Complete the APsystems installation map.

Each APsystems microinverter has two removable serial number labels. Peel labels off, affix one to the

respective location on the APsystems installation map, and affix another to the PV module frame which is

easy to see. Use the Scanning Gun to scan the serial numbers on the map into the computer or scan by

mobile phone, then complete the setting (see ECU manual).

NOTE: Step 1~10 can change sequence for convenience of installation.

Step 11. 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

five-minute waiting time.
