Microinverter Instructions
Installing the BDM‐250 Micro inverter System involves several key steps:
1. Measuring service and installing the AC branch circuit junction box.
WARNING: ONLY USE ELECTRICAL SYSTEM COMPONENTS APPROVED FOR WET LOCATIONS.
2. Attaching the BDM‐250 Micro inverter to the racking.
3. Connecting the BDM‐250 Micro inverter wiring harnesses.
4. Grounding the system.
5. Completing the BDM‐250 Micro inverter installation map and connecting the PV modules.
The finished system should be similar as in the diagram. Detailed installation steps are listed in the following
section.
Step 1 - Install the AC Branch Circuit Junction Box
