Lightning Surge Suppression
Lightning does not actually need to strike the equipment or building where PV system is installed to cause damage.
Often, a strike nearby will induce voltage spikes in the electrical grid that can damage equipment. BDM-600 has
integrated surge protection, greater than most string inverters. However, if the surge has sufficient energy, the
protection built into the BDM-600 can be exceeded, and the equipment can be damaged.
Since the NEP Limited Warranty does not cover “acts of God” such as lightning strikes, and since lightning strikes can
occur anywhere, it is best practice to install surge protection as part of any solar installation. Installation of surge
protection devices should follow vendor instructions.
Parts required
In addition to the micro inverters, PV modules, racking, and associated hardware, you’ll need the BDM-600 installation kit.
This kit includes the following items:
Protective end cap Male
Mounting Bracket (adapter plate)
Other Parts and Tools Required
In addition to your PV array and its associated hardware, you will need the following parts:
Junction box
Sockets, wrenches for mounting hardware
Procedure of Mounting
1. Measuring service and installing the AC branch circuit junction box.
ONLY USE ELECTRICAL SYSTEM COMPONENTS APPROVED FOR WET LOCATIONS.
2. Attaching the BDM-600 Micro inverter to the racking.
3. Connecting the BDM-600 Micro inverter wiring harnesses.
4. Grounding the system (optional).
DC circuits of BDM-600 are isolated and insulated from ground. An integrated ground protection circuit is included
in the micro inverter.
5. Completing the BDM-600 Micro inverter installation map and connecting the PV modules.
The finished system should be similar as in the diagram.
