How Do Different Inverter ACs Offer Stabilizer-Free Operations?

Modern inverter air conditioners are designed with built-in voltage regulation systems, allowing them to operate efficiently without external stabilizers in areas with a stable power supply. These systems enable the ACs to handle voltage fluctuations within a specified range, typically between 160V and 290V, by automatically adjusting the compressor's speed and power consumption. While inverter ACs offer stabilizer-free operation under normal conditions, assessing local power stability is crucial to determine the necessity of additional voltage protection.
