1. An apparatus comprising:
an input terminal configured to be connected to an output terminal of a photovoltaic power source;
a first output terminal;
a second output terminal;
a first switch configured to be connected to the input terminal;
a second switch configured to be connected to the first output terminal;
a third switch configured to be connected to the first output terminal;
a communication interface configured to receive one or more power line communication (PLC) signals; and
control circuitry configured to control the first switch, the second switch, and the third switch,
wherein the control circuitry is further configured to, based on the communication interface receiving the one or more PLC signals:
control the first switch and the second switch to be activated to create a first current path between the input terminal and the first output terminal; and
control the third switch to be deactivated, and
wherein the control circuitry is further configured to, based on the communication interface not receiving any PLC signals within a threshold time period:
control the first switch and the second switch to be deactivated to block a current from the input terminal from flowing to the first output terminal; and
control the third switch to be activated to create a second current path between the first output terminal and the second output terminal.
