lbs. Install a minimum 10 AWG solid copper or stranded
grounding wire. Torque terminal screw to 20 in-lbs.
➢ Ground Lugs are only needed on one rail per continuous row of
modules, regardless of row length (unless frameless modules are
being used, see Page 20).
➢ If using Enphase microinverters or Sunpower AC modules,
Grounding Lugs may not be needed. See Page 9 for more info.
