Domestic photovoltaic power generation system

Abstract

The invention discloses a domestic photovoltaic power generation system. Compared with the ordinary system, the domestic photovoltaic power generation system has the advantages that the effective light illumination time and the service life of a batter pack are greatly prolonged, and the goal of utilizing the solar energy to the greatest degree is reached. The domestic photovoltaic power generation system is provided with lightning protection measures for protecting the whole system, the east and west self-tracking sun movement is also adopted, in addition, the alternating current and direct current inverse power supply is automatically switched, when the effective light illumination time cannot be reached, alternating current and direct current are automatically and linearly superposed, and the solar energy is fully utilized for charging a storage battery pack. The system adopts the double-input alternating current and direct current superposition technology for solving the problems of higher harmonic elimination and phase position regulation of the ordinary photovoltaic converted direct current and electric network superposition. The domestic photovoltaic power generation system can solve the ordinary power consumption requirement of families, the system structure is simple, the use is more precise, and the domestic photovoltaic power generation system has the advantages that the stability is high, the installation is convenient, the operation is simple, the dismounting and the moving are convenient, and the like. The domestic photovoltaic power generation system is particularly suitable for the daily power supply of regions far away from an electric network, power limitation regions or disperse resident villages.

Description

technical field [0001] The invention relates to the technical field of solar energy applications, in particular to a household photovoltaic power generation system. Background technique [0002] As a new energy source, solar energy is inexhaustible and inexhaustible. At the same time, because solar energy is a clean energy source, it will not produce waste residue, waste water, waste gas, and noise during development and utilization, and will not affect the ecology. Balanced, it will never cause pollution and public nuisance, so it is widely favored by people today when environmental protection is advocated. Solar power generation is a common way of utilizing solar energy. The current solar power generation uses large-scale power stations for solar power generation. Large-scale solar power stations are only suitable for public use due to their large scale, high cost, and large footprint. Electricity generation, not suitable for ordinary household use. For ordinary families...
