Problems solved by technology

[0004] However, the technique described in Japanese Patent Application Laid-Open No. 2010-284060 has a disadvantage in that the electric power that can be supplied to the load during a power outage is only the electric power charged into the power storage device, and the power charged into the power storage device is disadvantageous. When the power is exhausted, the power supply to the load is cut off

Embodiment Construction

[0018] Next, use figure 1 , the configuration of the power supply system 1 according to one embodiment of the present invention will be described.

[0019] The power supply system 1 is installed in a house or the like, and supplies power from a commercial power supply 100 and power generated by natural energy to a specific load. The power supply system 1 mainly includes a power generation unit 10 , a power conditioner 20 , a switchboard 30 , a power storage device 40 , a load 50 (a specific load), other loads 80 , a home server 60 , a mobile terminal 70 , and the like.

[0020] The power generation unit 10 is a device that generates power using sunlight, and is composed of a solar cell panel or the like. Power generation unit 10 is installed, for example, on a roof of a house.

[0021] The power conditioner 20 has a function of converting the direct current generated by the power generation unit 10 into alternating current and matching the voltage, frequency, and phase of th...

Abstract

Provided is a power supply system which can supply more power to a load in the case of power failure. A power supply system (1) is provided with a power generating unit (10) that can generate power using natural energy, and an electric storage apparatus (40), which is connected to a commercial power supply (100) and the power generating unit (10), and can be charged with power supplied from the commercial power supply (100) and the power generating unit (10), and the power supply system supplies power supplied from the power generating unit (10), the electric storage apparatus (40) and the commercial power supply (100) to a specified load (50). In the cases where the commercial power supply (100) can be used, the electric storage apparatus (40) is capable of being charged with power supplied from the commercial power supply (100) and the power generating unit (10), and when the commercial power supply (100) fails, the electric storage apparatus is capable of being charged with power supplied from the power generating unit (10), while discharging the charged power to the specified load (50).

Description

technical field [0001] The present invention relates to a technology of an electric power supply system including an electric storage device capable of supplying electric power from the electric storage device to a specific load in the event of a commercial power failure. Background technique [0002] Conventionally, there is known a technology of an electric power supply system including an electric storage device capable of supplying electric power from the electric storage device to a specific load in the event of a commercial power failure. For example, it is described in Japanese Unexamined Patent Application Publication No. 2010-284060. [0003] In the power supply system described in Japanese Patent Laid-Open No. 2010-284060, when the commercial power supply fails and the power supply from the commercial power supply to the load is cut off, the power supply system can supply the power charged in the power storage device to this load, thereby replacing the commercial ...
