Abstract:
1. An integrated photovoltaic (PV) system, comprising: a plurality of identical DC output PV solar panels; a plurality of identical power rated and programmed PV inverters operating in parallel and being connected in parallel on their respective outputs, and connected one each exclusively on its input to a respective one of said plurality of said PV solar panels; a bio-friendly DC power unit; a control circuit connected to said bio-friendly DC power unit; and a further inverter of identical power rating to said plurality of said PV inverters and programmed as said plurality of said PV inverters, connected on its input to the output of said DC power unit and connected on its output in parallel to said plurality of inverters parallel output connection; wherein said control circuit is programmed to control said bio-friendly DC power unit to supply the same power to said further inverter as each of said plurality of said PV solar panels supplies to said plurality of said PV inverters, when said plurality of said PV solar panels are outputting power; wherein said control circuit is programmed to selectively connect said DC power unit in parallel to the input of each of said plurality of said PV inverters and to said further inverter when said plurality of parallel operating PV solar panels are not operative, wherein said DC power unit is controlled to supply substitute power to said plurality of said PV inverters; and wherein said parallel output connection of said plurality of said PV inverters and said further inverter is connected to an electric system.
