Step 1: Plan and install the Microinverter
- Mark the position of each microinverter on the rail according to the PV module layout.
- Fix the xxxx on the rail.
- Hang the microinverter on the screws and tighten them. The silver cover side of the microinverter should be facing the panel.
- Ensure proper grounding by using the earth wire inside the cable or by using the grounding electrode.
- Install the microinverter and all DC connections under the PV module to protect them from direct sunlight, rain, snow, and UV exposure.
- Leave at least 2 cm of space around the microinverter enclosure for ventilation and heat dissipation.
- Use a torque of 9 N·m to tighten the 8 mm screws. Do not over-torque.
- Avoid pulling or holding the AC cable with your hand. Hold the handle instead.
Step 2: Plan and build the AC Bus Cable
- Select the appropriate AC Trunk Cable based on the spacing between microinverters.
- Determine the number of microinverters on each AC branch and prepare AC Trunk Connectors accordingly.
- Disassemble the AC Trunk Connector and remove the cable.
- Install the AC Trunk End Cap at one side of the AC Trunk Cable.
- Install the AC end cable on the other side of the AC Trunk Cable, connected to the distribution box.
- Tighten the screws and cap of the AC Trunk Connector.
- Lay out the cable on the rail and fix it with tie wraps.
Step 3: Complete the AC Connection
- Push the AC Sub Connector from the microinverter to the AC Trunk Connector until it clicks.
- Connect the AC end cable to the distribution box and wire it to the local grid network.
- Plug the AC Trunk Port Cap in any vacant AC Trunk Port to make it water and dust-proof.
Step 4: Create an Installation Map
- Peel the removable serial number label from each microinverter.
- Affix the serial number label to the respective location on the installation map.
Step 5: Connect PV Modules
- Mount the PV modules above the microinverter.
- Connect the PV modules' DC cables to the DC input side of the microinverter.
Step 6: Energize the System
- Turn on the AC breaker for the branch circuit.
- Turn on the main AC breaker for the house. Your system will start to generate power in about two minutes.
Step 7: Set up Monitoring System
- Refer to the DTU User Manual or DTU Quick Installation Guide, and Quick Installation Guide for S-Miles Cloud to install the DTU and set up the monitoring system.
Please note that the provided information is a summary of the installation steps. For detailed instructions and illustrations, it is recommended to refer to the hoymiles HM-2000T-S Series Micro-Inverter Installation Guide available on the manufacturer's website.
