Conduits

Electric current runs from the array to the other components of the system through conduits. These run first from the panels to a combiner box, and then to an inverter.

Next, in an off-grid system, the conduit leads from the inverter to a battery storage system. This is where the cables will enter the building, since the battery system is located indoors.

In a grid-tied system, the conduit leads from the inverter to an electric meter, passing through an AC disconnect switch in between. This switch can be used to isolate the PV system from the power grid.
