no. 2 Embodiment approach

[0087] Next, according to Figure 4 A second embodiment in which the power management system according to the present invention is embodied will be described. Figure 4 It is a figure which schematically shows the form in which the communication between the electricity meter 29 and the power conditioner 50, and the communication between the power conditioner 50 and the display device 43 are all performed by wireless communication.

[0088] Among them, the second embodiment is different from the previous first embodiment in that the communication between the electricity meter 29 and the power conditioner 50 and the communication between the power conditioner 50 and the display device 43 are both different. It is performed by wireless communication, and otherwise it is the same as the previous first embodiment. Therefore, in this embodiment, differences from the first embodiment will be mainly described, and the same reference numerals will be assigned to the same configuration...

Abstract

Disclosed is an electric power management system equipped with an electric power meter connected to the electric power system of a commercial electric power supply; and a power conditioner connected to said electric power meter, to electricity generation devices, and to electrical devices. The system is characterised in that the electric power meter and the power conditioner exchange electric power information via a communication means.

Description

technical field [0001] The present invention relates to a power management system having a power conditioner for connecting power generated by a power generating device such as a solar power generating device with power of a commercial power supply system. Background technique [0002] In recent years, houses, offices, etc. equipped with photovoltaic power generation devices (solar cells) have been increasing. A solar cell has power generation characteristics such that the amount of power generated increases when the illuminance of sunlight is high, and on the contrary, the amount of power generated decreases when the illuminance of sunlight such as on a rainy day is low, and no power is generated at night when there is no sunlight. Therefore, this power generation pattern does not match the power consumption pattern in houses and the like, and the amount of generated electric power is often excessive or insufficient relative to the amount of consumed electric power. Theref...
