Currently, the scale of global demand for energy storage batteries continues to climb, the market growth rate is also increasing, China as the world's largest energy storage battery market, accounting for 33% of the global market share, it is expected that by the end of 2025, the cumulative installed size of electrochemical energy storage will reach 70GW, and lithium-ion batteries, as a major technological route for electrochemical energy storage, also occupies a dominant position in the market. At the same time, policy support also makes the power market commercialization mechanism continue to improve, energy storage business model is clearer, and the demand for energy storage equipment is also increasing.

Grid-Tied Inverter: Grid-tied inverters, also known as grid-connected inverters, are designed to convert the DC power generated by renewable energy sources, such as solar panels or wind turbines, into AC power that can be fed directly into the utility grid. Their key features and advantages include:

At present, the safety standards of lithium ion batteries in the industry mainly include international standards (such as IEC standards), national or regional standards (such as JIS, CB, EN standards, etc.) and industry standards (such as UL, IEEE, SJ, QB standards, etc.).

DC power (battery, storage battery) is converted into AC (generally 220V, 50Hz sine wave). It consists of inverter bridge, control logic and filter circuit. Widely used in air conditioners, home theaters, electric grinding wheels, electric tools, sewing machines, DVD, VCD, computers, TVs, washing machines, range hoods, refrigerators, VCRs, massagers, fans, lighting, etc.

Lithium iron phosphate battery has a series of unique advantages such as high working voltage, high energy density, long cycle life, low self-discharge rate, no memory effect, and green environmental protection, and supports stepless expansion, suitable for large-scale electric energy storage. It has a good application prospect in the fields of safe grid connection of renewable energy power station, peak regulation of power grid, distributed power station, UPS power supply, emergency power system and so on.

Batteries have a safe voltage range to use, the highest and lowest voltage is generally known as the charge and discharge termination voltage or cut-off voltage, when the actual working voltage of the battery for a long time is lower than the discharge termination voltage or a long time is higher than the charging termination voltage, irreversible damage will occur inside the battery, serious damage to the battery, resulting in performance decline, commonly known as battery attenuation, The performance of battery attenuation is that the internal resistance of the battery increases, the capacity decreases and so on. Therefore, there is generally a small PCB board inside the lithium-ion battery, which is packaged together with the battery, as shown in the figure below. The main function is to protect the battery.

Household energy storage system mainly refers to the energy storage system installed on residential buildings. Its operation modes include independent operation, supporting operation with small fans, rooftop photovoltaic and other renewable energy power generation equipment, and household heat storage equipment. The application of home energy storage system includes: electricity management, control of electricity cost (low charge and high discharge); Power supply reliability; Distributed renewable energy access; Electric vehicle energy storage battery application.

Usually, when choosing batteries, the first thing we need to consider is the performance of these types of batteries, because only batteries with good performance in all aspects can play a better role in the use process.
