Zo.ao.o2~ Electrical Production and Distribu- tion Network. A power production, distribution, and utilization system, such as a utility system and connect- ed loads, that is external to and not controlled by the photovoltaic power system. Inverter Input Circuit. Conductors between the inverter and the battery in stand-alone systems or the con- ductors between the inverter and the photovoltaic output circuits for elec- trical production and distribution network. Hybrid System. A system comprised Inverter Output Circuit. Conduc- of multiple power sources. These tors between the inverter and an ac power sources may include photovol- load center for stand-alone systems taic, wind, micro-hydro generators, or the conductors between the in- engine-driven generators, and others, verter and the service equipment or but do not include electrical produc- another electric power production tion and distribution network sys- source, such as a utility, for electri- tems.

Inverter. Equipment that is used to change voltage level or waveform, or both, of electrical energy. Common- ly, an inverter [also known as a power conditioning unit (PCU) or power conversion system (PCS)] is a device that changes do input to an ac output. Inverters may also function as battery chargers that use alter- nating current from another source and convert it into direct current for charging batteries. Photovoltaic Output Circuit. Cir- cuit conductors between the photo- voltaic source circuit(s) and the inverter or do utilization equipment. Photovoltaic Power Source. An array or aggregate of arrays that generates do power at system voltage and current. Photovoltaic Source Circuit. Cir- cuits between modules and from modules to the common connection point(s) of the do system. 710-15 (Pleasanton April 2003)
