DC system Earth connection

  1. May 22, 2010 #1
    On a low-voltage DC Solar system(up to 48V nominal), should I leave the lines floating or one should be grounded?

    I don't see any real advantage on any option...that's why I ask to confirm

    I think it would only matter if two people developed their own standard and tried to connect two systems together without agreeing which side was earthed.
