Single-phase Microinverter HMS-700/800/900/1000-2T-NA
The AC cable contains earth wire, so grounding can be done directly with it. For regions that have special
requirements, we offer optional grounding brackets that can be used to complete the external ground
-
ing.
Route a continuous grounding cable through grounding brackets for each microinverter to the AC
grounding electrode that conforms with local regulations.
Torque each grounding cleat screw to 2 N·m.
Note:
1. Microinverter installation and DC connections must be done under the PV module to avoid direct sunlight,
rain exposure, snow buildup, UV etc.
2. Leave a minimum of 2 cm of space around the microinverter enclosure to ensure ventilation and heat dissi-
pation.
3. Mounting torque of the 8 mm screw is 9 N·m. Do not over torque.
4. Do not pull or hold the AC cable with your hand. Hold the handle instead.
Step 2. Plan and Build the AC Trunk Cable
AC Trunk Cable is used to connect the microinverter to the power distribution box.
A ) Select the appropriate AC Trunk Cable according to the spacing between microinverters. The connec-
tors of the AC Trunk Cable should be spaced based on the spacing between microinverters to ensure
that they can properly matched. (Hoymiles provides AC Trunk Cable with different AC Trunk Connec
-
tor 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.
- Unlock the connector’s upper
cover with AC Trunk Connector
Unlock Tool.
1 ) Disassemble the AC Trunk Connector and remove the cable.
