PROBLEM TO BE SOLVED: To provide industrial photovoltaic power generation equipment, capable of supplying electric power charged in a storage battery to a power conditioner after the sunset by storing surplus power while supplying electric power generated by a solar panel to a system during the daytime.SOLUTION: The photovoltaic power generation equipment is provided with a step-up and step-down constant-current circuit because a current or a voltage remarkably changes depending upon sunshine conditions, and always monitors electric power from a solar panel and electric power of a storage battery through a small microcomputer to always supply constant power and supplies the electric power from the storage battery when insufficient power occurs or no input occurs from the solar panel for a certain period. |
