2. Installation Steps
1. Accessories
Step 1. Plan and install the Microinverter
All accessories above 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 AC Trunk Connector Unlock Tool to
unlock the connector upper cover.
1 ) Disassemble the AC Trunk Connector and remove the cable.
2 ) Install the AC Trunk End Cap at one side of AC Trunk Cable (The end of AC Trunk Cable).
- Loosen the three screws with screwdriver.
Untighten the cap and remove the cable.
*Note:

A ) Mark the position of each microinverter on the rail, according to the PV module layout.
Step 2. Plan and build the AC Trunk Cable
AC Trunk Cable is used to connect the microinverter to distribution box.
A ) Select the appropriate AC Trunk Cable according to the spacing between microinverters. The connector spacing of
the AC Trunk Cable should be close to spacing between microinverters to ensure that they are well-matched. (Hoymiles
provides AC Trunk Cable with different AC Trunk Connector spacing.)
B ) Determine how many microinverters you plan to install on each AC branch and prepare AC Trunk Connectors
accordingly.
C ) Take out segments of AC Trunk Cable as you need to make AC branch.
B ) Fix the screw on the rail.
C ) Hang the microinverter (label side up)
on the screws and beneath the PV module.
Then tighten the screws.
- Insert the AC Trunk End cap and screw the
cap back to port, then tighten the cap.
- Plug the upper cover back to the Trunk
connector.

3. Leave at least 2 cm of space around the microinverter enclosure to ensure ventilation and heat dissipation.
4. Mounting torque of the 8 mm screws should be 9 N·m.Please do not over-torque.
5. Do not pull or hold the AC cable with your hand. Hold the handle instead.
Note:
1. There is an earth wire inside the wire cable and the grounding can be done directly by this wire.
If external grounding is needed, the grounding accessories, as shown on the right, can be used to bond
the mounting bracket to the racking. Torque each grounding cleat screw to 2 N•m.
2. Install the microinverter and all DC connections beneath the PV module to avoid direct sunlight, rain
exposure, snow buildup, UV, etc.

Step 5. Connect PV Modules
Step 6. Energize the System
A ) Mount the PV modules 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. Please do not over-torque.
2. Torque of locking screw: 0.4±0.1 N·m.
3. Do not damage the sealing ring in the AC Trunk Connector during disassembly and assembly.
Step 4. Create an Installation Map
A ) Peel the removable Wi-Fi Module Serial
Number Label from each microinverter.
B ) Affix the serial number label to the respective
location on the installation map (please refer
to the User Manual).
3 ) Install AC end cable on the other side of AC Trunk Cable (connected to the distribution box).
Note:
1. Make sure that the AC Trunk Connectors are kept away from any water-channeling surface.
2. In case you need to remove the inverter AC cable from AC Trunk Connector, please use the
AC Trunk Port Disconnect Tool and insert the tool into the side of AC Sub Connector to
complete the removal.
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.
(Skip this step if there is no cable at this side.)
- Prepare a segment of AC cable 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 PE lines are in corresponding slots.
- Tighten the screws and tighten the cap back
to the port.
- Plug the upper cover back to the Trunk
connector.

B) Turn on the main AC breaker for the house. Your system will start to generate power in about two minutes.
E ) Attach the AC Trunk Cable to the mounting
rail and fix the cable with tie wraps.
A ) Push the AC Sub Connector from microin-
verter to the AC Trunk Connector until it clicks.
C ) Please plug the AC Trunk Port Cap in any
vacant AC Trunk Port to make it water and
dust-proof.
