NEP BDM-800 - 5. Commissioning; 5.1 Commissioning Steps; 5.2 Inverter;RSD Serial Input

5. Commissioning
WARNING: CONNECT BDM-800 TO THE ELECTRICAL UTILITY GRID ONLY AFTER RECEIVING PRIOR APPROVAL FROM THE UTILITY
COMPANY.
WARNING: BE AWARE THAT ONLY QUALIFIED PERSONNEL CAN CONNECT BDM-800 TO THE ELECTRICAL UTILITY GRID.
WARNING: ENSURE THAT ALL AC AND DC WIRING IS CORRECT. ENSURE THAT NONE OF THE AC AND DC WIRES IS PINCHED OR
DAMAGED. ENSURE THAT ALL JUNCTION BOXES ARE PROPERLY CLOSED.
5.1 Commissioning Steps
● Switch on the AC disconnects or circuit breakers of each BDM-800 AC branch circuit.
● Activate the main utility-grid AC circuit breaker to initiate power production. Please allow for a few minutes of
wait time.
● The BDM-800 will begin transmitting performance data through power line communication (PLC) to the
BDG-256. The duration for each BDM-800 in the system to communicate with the BDG-256 will vary depending
on the number of BDM-800s installed.
5.2 Inverter/RSD Serial Input
To ensure a successful serial input process, it is essential to have a comprehensive site map that outlines the
sequence of serial number input. It is crucial to keep in mind that the module that is connected to the longer
DC connection on the inverter will end with the number 1, while the module connected to the shorter DC
connection will end with the number 0.
5.2.A Manually on Device
● One method of inputting serial numbers is manually with the provided stylus directly into the gateway.
Although this method may be difficult for larger PV arrays, it can be a simple solution for small arrays. To input
serial numbers, navigate to Setting → COM ID on the gateway, where a list of empty cells and inverter numbers
will be displayed on the left side.
● To input serial numbers, locate the values between the dashes from the list of serials on your site map. For
example: 21508-0005F130-U. It's important to note which serial corresponds to each inverter/module number
on your site map for easier input later into the web portal. Once the serial number is inputted and saved, the
gateway will prompt a reboot.
