5.2 Connecting a PE Cable

Context
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. Low-voltage solar inverters need to be grounded in type C mode.
