All accessoriesabove are not included in the package and should be purchased
separately.
The order of Step 1 and Step 2 can be reversed according to your planned needs.
- Use the ACTrunk Connector Unlock Tool to
unlock the connector upper cover.

A ) Mark the position of each microinverter on the rail, according to the PVmodule layout.
Step 2. Plan and build the ACBus Cable
ACTrunk Cableis used to connect the microinverter to distribution box.
A ) Selectthe appropriate ACTrunk Cable according to the spacing between microinverters. The connector spacing of
the ACTrunk Cable should be close to spacing between microinverters to ensure that they are well-matched. (Hoymiles
provides ACTrunk Cablewith dierent ACTrunk Connector spacing.)
B ) Determine how many microinverters you plan to install on each ACbranch and prepare ACTrunk Connectors
accordingly.
C ) Take out segments of ACTrunk Cable as you need to make AC branch.
B ) Fix the screw on the rail.
C ) Hang the microinverter on the
screws, and tighten the screws. The silver
cover side of the microinverter should be
facing the panel.
- Insert the ACTrunk End cap and screw the
cap back to port, then tighten the cap.
- Plug the upper cover back to the Trunk
connector.

3. Leaveat least 2 cm of spacearound the microinverter enclosureto ensure ventilation and heat
dissipation.
4. Mounting torque of the 8 mm screwsshould be 9 N·m.Pleasedo not over-torque.
5. Do not pull or hold the ACcable with your hand. Hold the handle instead.
Note:
1. Thereis an earth wire inside the wire cable and the grounding can be done directly bythis wire.
If external grounding is needed,the grounding electrode,as shownon the right, can be used to
bond the
mounting bracket to the racking. Torqueeach grounding cleat screwto 2 N•m.
2. Install the microinverter and all DCconnections under the PVmodule to avoid direct sunlight, rain
exposure, snow buildup, UV,etc.

Step 5. Connect PV Modules
Step 6. Energize the System
A ) Mount the PVmodules above the
microinverter.
B ) Connect the PV modules’ DC cables to the
DC input side of the microinverter.
Note:
1. Tightening torque of the cap: 4.0±0.5 N·m.Pleasedo not over-torque.
2. Torque of locking screw:0.4±0.1 N·m.
3. Do not damage the sealing ring in the ACTrunk Connector during disassemblyand
assembly.
Step 4. Create an Installation Map
A ) Peel the removable serial number label from
each microinverter.
B ) Ax the serial number label to the respective
location on the installation map (pleaserefer
to the User Manual).
3 ) Install ACend cable on the other side of AC Trunk Cable (connected to the distribution box)
Note:
1. Makesure that the ACTrunk Connectors are kept away from any water-channeling
surface.
2. In case you need to remove the inverter ACcable from ACTrunk Connector, please
usethe

D ) Repeat the above steps, lay out the cable on the rail as appropriate so that the microinverters can be connected to
the Trunk connectors.
Step 3. Complete the AC Connection
- Unlock the port upper cover,loosen the screws
with screwdriver and remove the extra cable.
(Skipthis step if there is no cable at this side.)
- Prepare a segment of ACcable with suitable
length to connect to the distribution box, with
stripping requirements fulfilled.
- Insert the cable into the cap in a way that the
L, N and PElines are in corresponding slots.
- Tighten the screwsand tighten the cap back
to the port.
- Plug the upper cover back to the Trunk
connector.

B ) Connect the ACend cable to the distribution box, and wire it to the local grid network.
A) Turn on the ACbreaker for the branch circuit.
B) Turn on the main ACbreaker for the house. Your system
will start to generate power in about two minutes.
Step 7. Set up Monitoring System
Pleaserefer to the DTU User Manual or DTU Quick Installation
Guide, and Quick Installation Guide for S-MilesCloud to install
the DTUand set up monitoring system.
E ) Attach the ACTrunk Cable to the mounting
rail and x the cable with tie wraps.
A ) Push the ACSub Connector from microin-
verter to the ACTrunk Connector until it clicks.
C ) Please plug the ACTrunk Port Cap in any
vacant ACTrunk Port to make it water and
dust-proof.
