Installing a PE Cable

It is recommended that the PE
cable of the solar inverter be
connected to a nearby ground
point. Connect the PE points
of all solar inverters in the
same array to ensure
equipotential connections to
PE cables.
•
To enhance the corrosion
resistance of a ground
terminal, you are advised to
apply silica gel or paint on it
after connecting the PE cable.
