Installing your Hoymiles HM-800T solar microinverter correctly is key to maximizing its performance. Here's a straightforward guide to ensure a smooth setup:
-
Pre-Installation:
- Plan your AC trunk cable length to match the distance to each PV module.
- Install the AC Trunk End Cap: Unlock the port cover, loosen the screws, trim any excess cable, re-secure the cap, and insert the end cap.
-
Installation Steps:
-
Step 1: Mounting the Microinverter
- Mark the center point of each solar panel frame.
- Attach the Hoymiles HM-800T to the mounting rail, ensuring the silver cover faces the solar panel.
-
Step 2: AC Connection
- Secure the AC Trunk Cable to the mounting rail using ties.
- Connect the microinverter's AC connector to the trunk cable connector until you hear a click.
- Seal any unused bus ports with an AC Trunk Port Cap for weatherproofing.
-
Step 3: AC End Cable Installation
- Prepare an AC end cable of the appropriate length.
- Connect the L, N, and Ground wires into their designated slots, tightening the screws.
- Firmly reattach the cap.
- Connect the AC end cable's other end to your distribution box, integrating it with your local grid.
-
Step 4: Create an Installation Map
- Take the serial number labels from each microinverter and place them on the corresponding locations on your installation map.
-
Step 5: PV Module Connection
- Mount your PV modules above the microinverter.
- Connect the DC cables from the solar panels to the DC input side of the Hoymiles HM-800T.
-
Step 6: Energizing the System
- Turn on the AC breaker for the branch circuit, then the main AC breaker in your home to begin generating power.
-
Step 7: Setting Up Monitoring
- Consult the DTU User Manual and Quick Installation Guide to install the DTU and set up your monitoring system.
