Embodiment Construction

[0030] The embodiments described below are preferred detailed examples of the present disclosure, and various types of technically reasonable limitations thereof are given. However, the scope of the present disclosure is not limited to the embodiments described below unless the described points specifically limit the present disclosure.

[0031] Example of a power supply system

[0032] will refer to figure 1 An example of a power supply system according to the present disclosure is described. This system includes a solar cell 1 and a power storage device 2 . The solar cell 1 converts the energy of sunlight into electrical energy. The solar cell 1 is configured in such a way that a plurality of strings are configured by connecting a plurality of modules in series, each string is obtained by connecting a plurality of solar battery cells in series, and the plurality of strings connected in parallel are used for the array. in the unit.

[0033] The power storage device 2 use...

Abstract

A power supply system that comprises an electrical storage device; a power conversion circuit configured to convert a power from the electrical storage device into converted DC power; and a power control unit configured to receive the converted DC power and output AC power. The converted DC power is controlled such that the output AC power is a predetermined AC power.

Description

technical field [0001] The present disclosure relates to power supply systems and power supply devices. Background technique [0002] Recently, research and development on the utilization of renewable energy has become popular in order to get rid of dependence on fossil fuels. As power generation using renewable energy, photovoltaic power generation, wind power generation, fuel cells, biomass power generation, wave power generation, and the like have been developed. When renewable energy is used, there are problems in that the amount of power generation varies according to natural conditions, and excessive and insufficient power consumption occurs. For example, although household power consumption is high during a certain time period of the day, it is not limited to a time period that coincides with a time period when power generation is large. [0003] In order to solve this problem, it is conceivable to introduce a storage battery system into each home, and the output of...
