or 8 AWG
outdoor copper-core cable be used as a ground
cable. Ground cables must be securely
connected.
2. It is recommended that the ground cable be
connected to a nearby ground position. For a
system with multiple inverters connected in
parallel, connect the ground points of all
inverters to ensure equipotential connections.
3. To prevent corrosion, apply silica gel or paint to
the PE terminal after connecting the PGND
cable.
