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 (as shown on
the right) on the screws, and tighten the
screws.
- Insert the AC Trunk End cap and screw the

Grounding Accessory
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.
