An Inverter/UPS (Uninterruptible Power Supply) is a device that provides backup power to electrical systems during power outages or disturbances. It works by converting DC (direct current) power from batteries into AC (alternating current) to supply electricity to connected devices. Inverters are typically used in renewable energy systems and off-grid applications, while UPS systems are used to ensure continuous power for critical loads like computers, servers, and medical equipment. The primary difference between the two is that a UPS provides instantaneous power without any interruption, protecting sensitive equipment from power surges, voltage drops, and outages. Inverter/UPS systems come in various sizes and capacities, offering features such as surge protection, overload protection, and energy efficiency, making them essential for both residential and commercial use to maintain smooth operation and safeguard against electrical disruptions.
