Offer ESS,Residential Energy Storage Systems,Residential Energy Solution to You

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.	Generally composed of PV modules, lithium batteries, off-grid energy storage inverters, loads and diesel generators.	Generally composed of PV modules, grid-connected inverter, lithium batteries, AC coupling energy storage inverter, smart meter, CT, power grid and control system.
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.	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 grid is out of power, the lithium battery only supplies power to the off-grid load, and the grid-connected load cannot use. In addition, the system also supports users to set their own charging and discharging times to meet their power needs.	During the day, PV power generation first supplies the load and then charges the battery; At night, the battery discharges to supply the load. When the battery is insufficient, diesel generators supply the load.

Can participate in the optimized operation of the power grid to make electric energy use more efficient and economical.

WHAT ARE THE ADVANTAGES OF RESIDENTIAL ESS?

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.
