1. A system for controlling a plurality of electrical loads, the system comprising:an electrical control panel comprising:
a control circuit;
an alternating current (AC) line feed;
a direct current (DC) line feed configured to provide DC power from at least one DC power source;
a plurality of power supplies, where each power supply is configured to receive AC power or DC power and output DC power; and
a plurality of control modules, wherein more than one control module is associated with each of the plurality of power supplies, and each control module is configured to receive DC power from an associated power supply and provide a DC voltage to at least one electrical load; and
a grid-tie inverter electrically connected between the DC line feed and the AC line feed, the grid-tie inverter configured to receive DC power via the DC line feed, convert the DC power to AC power, and provide the AC power to the AC line feed;
wherein, based on one or more factors, the control circuit is configured to determine an amount of DC power received via the DC line feed to provide to one or more of the power supplies, and to determine an amount of DC power received via the DC line feed to convert to AC power and direct to the AC line feed.
