A wall-mounted battery refers to a type of battery that is specifically designed to be mounted on a wall or other vertical surface. These batteries are commonly used for energy storage purposes, allowing users to store excess energy generated from renewable sources or during off-peak hours for later use. Wall-mounted batteries are often compact and space-saving, making them suitable for residential, commercial, or industrial applications. They can be integrated into existing electrical systems to provide backup power during outages or to supplement the energy needs of a building. With their convenient installation and versatile functionality, wall-mounted batteries are becoming increasingly popular in the field of energy storage.
