DS3D Microinverter Quick Installation Guide
Step 1. Verify that grid voltage is matching with microinverter rating
Step 2. Y3 AC Bus Cable distribution
a. Each connector drop of the AC Bus cable shall be matching the position of the microinverter.
b. One end of the AC bus cable is used to access the junction box into the power grid.
c. Wire the conductors of the AC bus: L - BROWN; PE - YELLOW GREEN; N - BLUE; (European Standard).
NOTE: Wiring color code can be different according to the 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 damage
is not covered by the warranty.
Step 3. Attach the APsystems Microinverters to the Racking
NOTE: Install the microinverters (including DC and AC connectors) under the PV modules to avoid direct exposure to
rain, UV or other harmful weather events. Allow a minimum of 1.5 cm (3/4”) below and above the casing of the
microinverter to allow proper air flow. The racking must be properly grounded as per local electrical code.
ATTENTION: Do NOT carry the microinverter
by the AC cable. This may cause the AC cable to
partially or fully disconnect from the unit,
resulting in no or poor operation.
a. Mark the location of the microinverter on the rack, with respect to the PV module junction box or any other obstructions.
b. Mount one microinverter at each of these locations using hardware recommended by your module racking vendor.

Step 4. Ground the system
Y3 AC Bus cable has an embedded PE wire: this might be sufficient to ensure proper grounding of the whole PV array. However
in areas with special grounding requirements, external grounding work may still be needed, using the grounding lug supplied
with the Microinverter.

Step 5. Connect the APsystems Microinverter to AC bus cable
Insert the microinverter AC connector into the trunk cable connector. Make sure to hear the “click” as a proof of robust
connection.
Step 6. Install a Bus Cable End Cap at the end of AC bus cable
Step 7. Connect APsystems Microinverters to the PV Modules
NOTE: 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.
WARNING: 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.
WARNING: 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.

Best Practice: Use the AC Bus Cable Unlock Tool to disconnect
the connectors.

NOTE: 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 system is an even number.
Step 8. Complete the APsystems installation map
a. Each APsystems Microinverter has 2 removable serial number labels.
b. Complete installation map by sticking ID label of each microinverter at the right location.
c. The second serial number label, could be stuck on the solar module frame, which could help later to confirm the position
of the microinverter without dismantling the PV module.
NOTE:
.
The layout of the microinverters' serial numbers installation map is only suitable for typical
installation.
. Installation Map is available in the last page appendix of this manual.
. Use ECU_APP (available in the EMA Manager) to scan the serial numbers on the map when
setting up the ECU (see ECU instruction manual for more info).
