Enter the wattage of the appliances you plan to connect below. Our calculator will compute the total wattage, factor in a standard safety margin, and recommend the optimal KVA rating.
Every electrical appliance has a specifications sticker displaying its input wattage consumption (in Watts). If only Amperes and Voltage are listed, multiply them to get Watts: **Watts = Amps × Volts**.
Stabilizers are rated in KVA (Kilo-Volt-Amperes). To convert Watts to VA, divide the total wattage by the power factor (typically 0.8 for induction motors found in ACs and fridges): **VA = Watts / 0.8**.
During startup, inductive loads (compressors, motors) draw a brief surge current that is 2 to 3 times their running current. To prevent the stabilizer from tripping due to overloading, we add a 25% buffer: **Required VA = VA × 1.25**.
