what is home storage battery?

A home storage battery is a device that stores electrical energy for later use. It is typically used in conjunction with a renewable energy source, such as solar panels, to store excess energy that is generated during the day for use at night or during periods of high energy demand. A home storage battery system consists of a battery pack, an inverter, and a charging system. The battery pack stores the energy, the inverter converts the stored energy from direct current (DC) to alternating current (AC), and the charging system manages the flow of energy into and out of the battery pack.

Home storage batteries typically consist of a battery pack, an inverter, and a control system. The battery pack stores the excess electricity, while the inverter converts the stored electricity from direct current (DC) to alternating current (AC), which is the type of electricity used in homes and other buildings. The control system manages the flow of electricity between the battery pack, the inverter, and the home's electrical system.

There are several different types of batteries that can be used in home storage systems, including lead-acid, lithium-ion, and nickel-metal hydride. Each type of battery has its own advantages and disadvantages, and the choice of which to use may depend on the specific needs and requirements of the homeowner.

Home storage batteries can be used to provide backup power for homes and businesses during power outages or other emergencies. They can also be used to smooth out the flow of electricity from intermittent renewable energy sources, such as solar panels, by storing excess electricity for later use.

In addition to their use in residential settings, home storage batteries are also becoming increasingly popular in commercial and industrial applications. They can be used to store excess electricity generated by renewable energy sources, such as wind turbines or hydroelectric dams, for later use.

Overall, home storage batteries are an important technology that allows homeowners and businesses to more effectively use and manage their renewable energy resources. As the demand for renewable energy continues to grow, the development and deployment of advanced home storage batteries will become increasingly important in the effort to create a more sustainable and efficient energy system.

At this stage, 5,000 square meters have been put into use, with a monthly production capacity of 5 million US dollars. The second phase of the factory building is planned to add 5,000 square meters in the second quarter of 2023, and the monthly production capacity will reach 10 million US dollars by then. The third phase of the plant plans to add another 5,000 square meters in the fourth quarter of 2023, and the monthly production capacity will exceed 15 million US dollars.

Household energy storage batteries typically use lithium ion, lithium iron, or LiFePO4 (LFP) energy storage technology. Both technologies use electrolytes made of lithium salts and anodes made of high-quality graphite, but the cathode is the main difference. The cathode of lithium ion batteries is usually a metal oxide such as cobalt, nickel, or manganese, while the cathode of lithium iron batteries is iron phosphide. Lithium iron batteries have a longer lifespan, higher safety, and lower environmental impact than lithium ion batteries.

Household energy storage batteries typically need to be installed and debugged by professionals to ensure safety and efficiency. The installation process may take several hours to several days, depending on the complexity of the system and site conditions. After installation, you can monitor and control your system through mobile apps or web pages, and set your optimization goals. Household energy storage batteries generally do not require much maintenance, as long as they are regularly checked for damage or malfunction, and operated and maintained in accordance with the manufacturer's instructions.
