An "invertör" is a device that converts direct current (DC) into alternating current (AC). This process is essential for using solar energy systems, where solar panels generate DC electricity. The invertör allows this electricity to be used in homes and businesses, as most appliances operate on AC power. Invertörs are commonly used in various applications, including solar energy systems, uninterruptible power supplies (UPS), and electric vehicles. They come in different sizes and capacities, depending on the energy needs of the system they support. Proper selection and installation of an invertör are crucial for efficient energy conversion and usage.
