Reference these anchoring details when mounting Powerwall 3 to the provided mounting bracket.
Wood Studs (spaced at 12 to 17 inches) If anchoring directly into wood studs, use at least four (one in each corner) #14 (approx. ¼ inch dia.) wood screws with washers, of sufficient length for at least 2-½ inch embedment into the studs. Note See Channel Strut (Unistrut) for stud spacing
greater than 17 inches, up to 24 inches. Warning See
