Traditional residential energy supply mainly relies on the power grid, so it often faces the problem of unstable energy supply during peak periods or energy shortages. Meanwhile, traditional energy sources such as coal and natural gas have also had serious negative impacts on the environment. As an emerging solution, residential energy storage systems can effectively store renewable energy such as solar and wind energy, and provide them to households when needed, thereby reducing dependence on traditional energy, reducing carbon emissions, and achieving self-sufficiency in residential energy. WHAT IS A RESIDENTIAL ENERGY STORAGE SYSTEM (ESS)? Residential ESS is a device system used for home energy management, designed to store and manage electricity to meet the daily electricity needs of the home. It usually consists of photovoltaic (PV) power generation system, battery energy storage equipment, inverters, and other equipment. Therefore, this residential ESS is also known as residential solar energy storage system. At present, residential energy storage systems are mainly combined with PVs, forming hybrid, coupled, off-grid and other home PV + home energy storage systems. WHAT ARE THE DIFFERENCES BETWEEN THE FOUR TYPES OF RESIDENTIAL ESS? Hybrid home PV + home ESS Coupled home PV + home ESS Off-grid home PV + home ESS PV energy storage energy management system System Composition Generally composed of PV modules, lithium batteries, hybrid inverter, smart meter, CT, power grid, grid-connected loads and off-grid loads. Also known as AC retrofit PV + ESS, generally consists of PV modules, grid-connected inverter, lithium battery, AC coupled energy storage inverter, smart meter, CT, power grid , grid-connected load and off-grid load.

Battery Charging and Discharging Mode Directly charge the battery through DC-DC conversion of PV energy, and can also achieve bidirectional DC-AC conversion for battery charging and discharging. Convert PV power into AC power through a grid-connected inverter, and then convert the excess power into DC power through an AC-coupled energy storage inverter for storage in batteries. Directly charge the battery through DC-DC conversion of PV energy, and can also realize bidirectional DC-AC conversion for charging and discharging of batteries. Working Principle During the day, PV power generation first supplies the load, then charges the battery, and finally the excess power can be connected to the grid; At night, the battery is discharged to supply the load, and the shortfall is supplemented by the grid; When the power grid fails, PV power generation and lithium batteries only supply power to off-grid loads, and the on-grid loads cannot be used. In addition, the system also supports users to set their own charging and discharging times to meet their power needs.

Intelligent energy storage: Residential ESS adopts advanced lithium-ion battery technology to efficiently store large amounts of electricity. The system is equipped with intelligent energy management software that can optimize scheduling based on residential energy consumption patterns and renewable energy production patterns. When the renewable energy supply is sufficient, the system will automatically store excess energy; When the supply of renewable energy is insufficient, the system will automatically release the stored energy to meet the needs of households. This intelligent energy storage mechanism not only improves energy utilization efficiency, but also reduces energy waste. Flexible energy usage: Residential ESS also has flexible energy usage methods. By connecting to the power grid, the system can achieve bidirectional energy flow, that is, it can sell excess energy to the grid to obtain additional income; At the same time, when the power grid is unstable or interrupted, the system can also automatically switch to a backup power source to ensure the continuous supply of household electricity. This enables households to manage and use energy more independently, improving energy reliability and sustainability. Remote monitoring and control: The residential ESS also supports remote monitoring and control functions. Through a smartphone app or cloud platform, households can monitor the system's energy generation and consumption in real-time and make corresponding adjustments. For example, energy storage and usage patterns can be adjusted in advance according to the weather forecast to maximize the use of renewable energy. This remote monitoring and control function provides greater flexibility and convenience, allowing households to manage energy from anywhere and at any time. As an intelligent residential energy solution, residential ESS provides households with efficient, sustainable, and flexible energy storage and management methods. Through intelligent energy storage, flexible energy use, and remote monitoring and control functions, households can better utilize renewable energy, reduce energy costs, reduce dependence on traditional energy, and contribute to environmental protection. With the continuous progress of renewable energy technology, residential energy storage systems are being accepted by more and more households.

For network operators, Aulanbel’s battery energy storage solutions provide grid services such as frequency response, renewable energy integration, capacity reserve and ramp rate control. Utility scale battery storage stores electricity during low power demand periods and releases electricity during peak power demand periods, thereby smoothing the power load curve and ensuring the stability of energy supply. Utility scale battery storage can realize energy time displacement, that is, separating the generation time and usage time of energy. By storing excess renewable energy capacity and releasing it when needed, energy storage systems can provide a continuous supply of electricity that can meet demand even when renewable energy generation equipment is unable to produce enough energy. Utility scale battery storage usually works closely with power markets or energy operators to participate in power trading activities. The energy storage system can buy and sell energy according to market demand to maximize profits and optimize energy supply. Energy storage systems can also participate in existing electricity market mechanisms, such as power purchase agreements (PPA) or capacity markets, to earn revenue by selling stored energy or providing reserve services. In addition, utility scale battery storage can also be integrated and managed through a virtual power plant (VPP). The VPP integrates multiple distributed energy storage systems (DESS), unifies dispatching and operations, and achieves overall response to the power system and energy supply regulation. By implementing utility scale battery storage solutions, power systems can achieve greater reliability, flexibility and sustainability.

When you plan to buy an electric vehicle (EV), charging speed will be at the forefront of your mind, as it will directly affect your daily travel plans. Currently, DC fast charging is the fastest way to charge EVs and plays an important role in public EV charging infrastructure. DC fast charging stations are an ideal choice for electric car drivers who need to quickly charge their cars during long journeys, and are also ideal for drivers who temporarily need to quickly charge their car batteries during daily travel. Electricity in an EV's battery is stored as direct current (DC), while the grid provides alternating current (AC) power. Inside an EV, there is an on-board charger that converts AC to DC and then distributes the power to charge the vehicle's battery. DC fast charging can bypass the on-board charger and charge the battery directly, thus greatly shortening the charging time of EVs. This is because the conversion of power from AC to DC occurs in the DC charging station before being output to the vehicle. Therefore, DC fast charging can provide a faster charging experience for EVs than AC charging. Aulanbel EV charging solutions can be used in a wide range of commercial, public and fleet charging sites. In the time it takes for you to eat a meal on the road, a fast charging station can quickly extend the range of your electric car. Aulanbel EV charging solutions can not only solve the problem of fast charging for you, but also improve charging services, optimize energy costs and cope with power peaks through energy storage systems (ESS), maximizing the efficiency of the solar power supply system in charging stations, allowing you really enjoy the benefits of shaving peaks and filling valleys.
