1. An electrical supply system, comprising:
a carport appliance, comprising:
a rectangular framework having a length L, a width W, and a height H, comprising four corner posts of d″×d″ square metal tubing with cross beams at the upper ends of the posts forming a rectangular top;
a rectangular base plate of width W, length L and thickness T equal or less than 1″ lying flat on a support surface with the corner posts of the rectangular framework joined securely to the baseplate at corners of the baseplate;
a plurality of PV panels mounted to the top of the rectangular framework in a horizontal aspect in a pattern covering substantially all area of the top of the framework;
a plurality of PV panels hinged along a long edge of each PV panel to a top edge of a first side of the framework, and a plurality of PV panels hinged along a long edge of each PV panel to a top edge of a second side of the framework;
one PV panel of a length equal to width W of the rectangular framework, hinged along the length of the PV panel to a top edge of a first end of the framework, and one PV panel of a length equal to width W of the rectangular framework, hinged along the length of the PV panel to a top edge of a second end of the framework;
support apparatus hinged to posts on each side of the framework, adapted in a raised position to support the plurality of PV panels hinged on each side of the framework with the PV panels rotated upward to a horizontal aspect;
support apparatus hinged to posts on each end of the framework, adapted in a raised position to support the one PV panel hinged on each end of the framework with the PV panels rotated upward to a horizontal aspect; and
circuitry and wiring connecting the PV panels to a cable ending in a connector compatible with a PV inverter; and
a system controller, comprising:
a framework enclosing elements of the system controller, the framework mounted on a wheeled base;
a PV inverter connected to the cable from the PV panels as input to the system controller;
a regulated bus;
apparatus coupled to the regulated bus adapted to provide surge protection; and
circuitry and conductors adapted to connect an AC output of the system controller to an electrical grid.
