Household solar power generation storage management system

Abstract

The invention discloses a household solar power generation storage management system, which is characterized in that a clean energy module can charge an energy storage module, the energy storage module comprises a main energy storage module and a standby energy storage module, is used for storing solar energy or charging and storing energy from a mains supply power grid, and can supply power to household equipment, and when the clean energy module works and the output power is greater than a threshold value, the clean energy module preferentially charges the main energy storage module, the main energy storage module does not supply power to the outside at the moment, and charging is stopped until the electric energy stored by the main energy storage module reaches a specified value. According to the energy storage management system, the combination of the main energy storage module and the standby energy storage module is adopted, the stability of the system can be greatly improved, and the scene of secondary recycling of the power lithium battery can be well met; and the algorithm is adopted to predict the next-day total generating capacity, the battery is maintained in a reasonable energy interval as far as possible, aging can be effectively delayed, the service life of the battery is prolonged, and the use cost is reduced.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a household solar power generation storage management system. Background technique [0002] The global climate and environment are deteriorating day by day, and people's awareness and demand for clean energy are becoming stronger and stronger. As a kind of clean energy, solar energy resources can effectively reduce carbon emissions and speed up the progress of carbon neutrality through rational use. At the same time, solar power generation technology is becoming more and more mature, and the power generation efficiency is getting higher and higher, and the government has also issued relevant policies to encourage the installation and use of solar energy equipment. [0003] The solar panel in the existing photovoltaic power generation system has a long service life, which can reach more than 20 years, while the energy storage battery part has a short service life, generally ...

AI Technical Summary

Problems solved by technology

[0004] At present, the products closest to the present invention on the market have solar self-charging, solar maximum power tracking, home off-grid power supply, manual control of the product's working mode through human-computer interaction equipment, and the use of a single threshold control is likely to greatly reduce the service life of the energy storage battery

Existing solar energy systems cannot intelligently allocate solar energy to charge energy storage batteries according to daily weather changes, daily power peaks, sudden natural disasters, etc., cannot effectively prolong the service life of energy storage batteries, and are not suitable for power batteries secondary use
