Choosing the right wattage is essential. A 1 ton AC stabilizer watt rating typically ranges between 2000W to 3000W, depending on efficiency and voltage range. For 1.5 ton ACs, we recommend a 5kVA stabilizer for AC, especially if you experience voltage drops. If you're using an inverter AC, make sure you get the best stabilizer for 1.5 ton inverter AC with features like time-delay and surge protection. Copper-wound options are best for durability and better power handling.
