Installing a PE Cable
4.2
•
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.
