What to do if my NEP BDM-300X2 Inverter BDM-600 is inoperable?
- MMichael MartinezAug 9, 2025
If your NEP BDM-600 inverter isn't working, start by checking the connection to the utility grid, ensuring the voltage and frequency are within acceptable ranges. Also, remove AC and DC power to verify utility power is present at the inverter. Then, reconnect the DC module connectors and watch for LED blinks. Check the AC branch circuit interconnection harness between all BDM-600s to ensure each inverter is energized by the utility grid. Confirm any AC disconnects are functioning correctly and are closed. Verify the PV module DC voltage is within the allowable range, and inspect the DC connections between the BDM-600 and the PV module.
