5.2 Grounding
5.2.1 Solahart modules use an anodic oxidized aluminum frame to resist corrosion. So the frame of
modules should be grounded to prevent thunder and electrical shock. The grounding device should fully
contact with the inside of the aluminum alloy, and penetrate the surface of the frame oxidation film.
5.2.2 Solahart recommends using the following methods to ground modules for rooftop PV installations
only:
Universal clamp with Earthing plate for frame
height 30 to 46 mm (C-U/30/46-G)
To earth modules and rails, use Clenergy Universal
Clamps with earthing plates (C-U/30/46-G) when
mounting modules. Install the clamps in accordance
with the following instructions. When installed
correctly, earthing plates will provide earth bond
continuity between rails and modules whilst allowing
removal of a module without affecting the earthing
integrity of other components in the system.
Universal Clamps with built-in earthing plates suit PV
modules of thickness between 30
mm to 46
mm and
can be used as either mid clamps or end clamps.
Twisting the head of the clamp changes the
functionality from end clamp to mid clamp.
When using as end clamp, slide the universal clamp to
the position to be fastened. Ensure there is at least 25
mm from the rail end. Then slightly slide the PV Module
frame onto the earthing plate of universal clamp. Make
sure the frame of PV Module is fully in contact with the
universal clamp. Ensure that the end clamps are tight
against the module. Then tighten the universal clamp
bolt to minimum 17 Nm.
