Grounding of the module frame can be achieved through use of clamps that penetrate the
anodization in conjunction with grounding of the mounting system or through direct
grounding of the frames by attaching a copper wire to a grounding hole of each module (bolt
size, M6 × 1.0 × 50).

For optimal performance, BenQ Solar modules should only be used in conjunction with
galvanically insulated inverters
where the negative (-) polarity of the PV array is connected to
ground protected by a fuse.
