The minimum voltage required for DC inverter air conditioners can vary depending on the specific model and manufacturer. However, most DC inverter air conditioners are designed to operate within a voltage range of 180V to 240V.
It's important to note that while DC inverter air conditioners can handle a wide voltage range, they may have limitations at the lower end. If the voltage drops below a certain threshold, the air conditioner may not function properly or may shut off altogether to protect the compressor and other components.
To ensure the reliable operation of a DC inverter air conditioner, it's recommended to have a stable power supply that meets the manufacturer's specified voltage requirements. Additionally, if you experience frequent voltage fluctuations or power outages in your area, it may be beneficial to invest in voltage stabilizers or surge protectors to protect your air conditioner and other electrical appliances.
