2. Installation Steps
The order of Step 1 and Step 2 can be reversed according to your planned needs.
Step 1. Plan and install the Microinverter
A ) Mark the position of each microinverter on the rail, according to the PV module layout.
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.
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 electrode, 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 under the PV module to avoid direct sunlight, rain
exposure, snow buildup, UV, etc.
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.
Step 2. Plan and build the AC Bus 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.
1 ) Disassemble the AC Trunk Connector and remove the cable.
- Use the AC Trunk Connector Unlock Tool to
unlock the connector upper cover.
- Loosen the three screws with screwdriver.
Untighten the cap and remove the cable.
2 ) Install the AC Trunk End Cap at one side of AC Trunk Cable (The end of AC Trunk Cable)
- 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.
