Abstract

The invention provides a household photovoltaic intelligent control system. The household photovoltaic intelligent control system comprises a confluence lightning arrester, an energy storage battery, a photovoltaic controller, an energy manager and a controller, wherein the photovoltaic controller is connected with the stretching end of the confluence lightning arrester a direct-current bus and the energy storage battery and used for controlling charging and discharging processes of the energy storage battery and controlling the energy storage battery to supply electricity to direct-current electricity loads; the energy manager is connected with the direct-current bus and an one-way electric energy meter and used for transmitting electricity energy in different directions according to different states of the electricity energy; the controller is connected with the photovoltaic controller, the one-way electric energy meter and the energy manager, used for collecting, processing and outputting electricity generating information of a photovoltaic array, and charging and discharging information and electric quantity information of the energy storage battery, and used for parameter setting and operation control of the system. The household photovoltaic intelligent control system can avoid large-scale system design and a construction process of a photovoltaic application system, and no electricity is wasted.

Description

technical field [0001] The present invention relates to the technical field of solar energy utilization and electric energy conversion. Specifically, the present invention particularly relates to a household photovoltaic intelligent control system suitable for small organizations such as families and businesses. Background technique [0002] In modern society, non-renewable energy is consumed in large quantities, energy problems are becoming increasingly prominent, and the consumption of households, which are one of the main energy users, continues to increase. How to solve this increasingly serious problem, people continue to try to use photovoltaic technology to meet part of the energy consumption of the family. But have not finished a comparatively reasonable technical scheme at present. The general off-grid system is simple in design and low in cost, but its photovoltaic utilization rate is low, and a large number of batteries need to be configured for electric energy s...
