Abstract: Systems and methods of electrically connecting electrical energy storage or photovoltaic equipment with electrical destination equipment without performing any hard-wiring or installing any terminations in the field. A utility-scale electrical energy storage system and/or photovoltaic inverter is provided with a receptacle at its electrical output with a frame shaped and sized to secure to a first plug on a first cable to form an electrical connection between the first source equipment, first cable and the destination equipment.

Abstract: Assemblies for supporting energy storage equipment, and more particularly, pre-fabricated, above-ground, affixed, ventilated or non-ventilated, power feeder chassis assemblies for large-scale electrical energy storage equipment, comprising a frame unit with certain features that make it capable of supporting energy storage equipment and a cable feeder with certain features that connect destination equipment to the electrical energy storage equipment. Various features of the assembly are described. Also described are methods of manufacturing the same, some of which are directed to methods of pre-fabrication, mass manufacture and transportability. Also described are methods of installing the same, some of which are directed to methods of laying out in grid patterns for large-scale projects.
