Climate controlled products such as air conditioners,heat exchanger, or TEC coolers are installed on outdoor battery cabinet for keeping a stable temperature inside cabinet so as to increase service life and stability of battery. . A battery storage cabinet provides a controlled, protective environment for storing lithium-ion batteries when they are not in use. While lithium batteries offer high energy density and excellent performance, their chemistry also makes them sensitive to temperature fluctuations, physical damage. . Laboratory-tested capacity ratings often assume operation in a narrow range—typically 20°C to 25°C. But real-world projects in hot deserts or freezing winters push far beyond these limits. This helps your solar system work better and stay safe longer.
