ABSTRACT:
Systems and methods provide a redundant electrical power supply solution, where an AC power source is called upon when a photovoltaic subsystem is unavailable to meet the power consumption needs of telecommunications site equipment. In one aspect, a system for supplying electrical power includes a DC bus with which telecommunications site equipment is coupled, as well as a photovoltaic subsystem and a second power delivery circuit. The photovoltaic subsystem includes a solar photovoltaic array, a disconnect for controlling electrical connection between the solar photovoltaic array and the DC bus, as well as a DC/DC voltage converter. The second power delivery circuit includes a rectifier for converting incoming AC voltage from an AC power source to output DC voltage delivered at the DC bus upon sensing a condition where the photovoltaic subsystem delivers insufficient DC voltage to the DC bus.
