The outdoor cabinet is a closed iron box. When the cabinet is exposed to the summer sunshine, the solar radiation heat will be transmitted into the cabinet through the sun drying surface. The temperature inside the cabinet will rise, which will cause the rectifier module or inverter module of the product and UPS will be shutdown due to over temperature protection. At the same time, the temperature inside the cabinet is too high, which is very unfavorable to the battery. No matter the adsorption type or the colloid sealed lead acid battery will cause the loss of water in the battery medium due to the high temperature. When the battery medium is lack of water, the conversion efficiency of the battery will decrease, and the failure of the battery is not output.
