During a power outage, a device called an inverter is used to prevent excess consumption. An inverter is a type of electrical device that converts DC direct current into AC alternating current and is used in most electric vehicle systems, power sources, and solar energy. Today, inverters are available in two types, single phase and three phase. Inverters are used in screw compressors to prevent wear and tear caused by shocks after loading and unloading the device, and they also prevent possible damage to the compressors' electric motors due to their strong control capability.
