Voltage fluctuations can harm electrical equipment in inverter air conditioners. Sometimes, they can cause permanent damage as well. So, it is important to connect AC to a voltage stabilizer. They protect the air conditioner by stabilizing the utility voltage. When there is a voltage fluctuation, the stabilizer regulates it and deliver consistent output voltage. For example, if the voltage is high, then it will reduce the intensity and send it out to the equipment. And vice-versa. To know how to select right stabilizer for your inverter AC, read this article
