Calculation Formula

Inverter Capacity (VA) = Total Wattage + Surge Wattage

Where:
Total Wattage: Total power consumption of all connected appliances.
Surge Wattage: The initial power surge when an appliance starts.

How to Use the Calculator

  1. Enter the total wattage of all appliances you plan to connect to the inverter.
  2. Enter the surge wattage of the heaviest starting appliance (e.g., refrigerator, air conditioner).
  3. Click the "Calculate" button to determine the required inverter capacity.
  4. The result will be displayed in VA (Volt-Ampere).

Understanding the Results

The required inverter capacity should be at least equal to the calculated value to ensure smooth operation without damage to the inverter.

Example

If you have appliances with a total wattage of 1500W and a heavy starting appliance (like an air conditioner) with a surge wattage of 3000W, the required inverter capacity would be 4500 VA.
