Diversion Charge Controller. Equipment that regulates <br />the charging process of a battery by diverting power from <br />energy storage to direct-current or alternating-current loads <br />or to an interconnected utility service. <br /> <br />Electrical Production and Distribution Network. A <br />power production, distribution, and utilization system, such <br />as a utility system and connected loads, that is external to <br />and not controlled by the photovoltaic power system. <br /> <br />Hybrid System. A system comprised of multiple power <br />sources. These power sources may include photovoltaic, <br />wind, micro-hydro generators, engine-driven generators, <br />and others, but do not include electrical production and <br />distribution network systems. Energy storage systems, such <br />as batteries, do not constitute a power source for the pur- <br />pose of this definition. <br /> <br />Interactive System. A solar photovoltaic system that oper- <br />ates in parallel with and may deliver power to an electrical <br />production and distribution network. For the purpose of this <br />definition, an energy storage subsystem of a solar Photovol- <br />talc system, such as a battery, is not another electrical pro- <br />duction source. <br /> <br />Inverter. Equipment that is used to change voltage level or <br />waveform, or both, of electrical energy. Commonly, an in- <br />verter [also known as a power conditioning unit (PCU) or <br />power conversion system (PCS)] is a device that changes <br />do input to an ac output. Inverters may also function as <br />battery chargers that use alternating current from another <br />source and convert it into direct current for charging batter- <br />ies. <br /> <br />Inverter Input Circuit. Conductors between the inverter <br />and the battery in stand-alone systems or the conductors <br />between the inverter and the photovoltaic output circuits for <br />electrical production and distribution network. <br /> <br />Inverter Output Circuit. Conductors between the inverter <br />and an ac load center for stand-alone systems or the con- <br />ductors between the inverter and the service equipment or <br />another electric power production source, such as a utility, <br />for electrical production and distribution network. <br /> 64 <br /> <br /> <br />
