Household energy storage is an important component of Distributed Energy Resources(DER).
Core components
Photovoltaic modules (solar panels): absorb solar radiation and convert it into direct current energy.
Energy storage equipment (battery system): such as lithium-ion batteries, used to store excess energy from photovoltaic power generation, in order to provide power support during periods of no sunlight or peak electricity consumption.
Photovoltaic storage inverter: including single-phase or three-phase inverters, its function is to convert the direct current generated by photovoltaic modules into alternating current for household use, and it also has a charging controller function to manage the charging and discharging process of the battery, and can operate in both directions. It can convert solar energy into alternating current, as well as convert the electricity in the grid or battery into alternating current suitable for household appliances.
Intelligent management system: monitors the operation status of the entire system, optimizes energy scheduling, ensures maximum utilization of solar energy resources, and can also interact with the power grid to participate in demand response, peak and valley electricity price arbitrage and other electricity market activities.
Working principle
During the day, solar panels convert sunlight into electricity, with a portion directly supplied to household loads, and excess electricity stored in the battery; When the sun sets or it is cloudy or rainy and unable to generate electricity effectively, the energy stored in the battery can be released to meet the household electricity demand, ensuring power supply stability and continuity.
Application scope
1.Reduce reliance on traditional power grids, especially in unstable or remote areas.
2.Provide backup power in the event of a power outage to improve quality of life and safety.
3.Utilize peak and flat valley electricity pricing policies to save electricity expenses, and achieve economic benefits by charging during low electricity price periods and discharging during high electricity price periods.
