Step-by-Step Generator Sizing Guide
- List all appliances and devices: Create a comprehensive list of every item you intend to run simultaneously. This includes lights, refrigerators, computers, water pumps, and any other essential equipment.
- Determine wattage for each item: Find the wattage rating (in watts) for each appliance. For appliances listing amperage (amps) instead, use the formula: Watts = Amps x Volts (usually 120V for household appliances). If only kilowatts (kW) are listed, multiply by 1000 to get watts.
- Calculate starting and running wattage: For each appliance, identify both the starting (surge) and running wattage. The starting wattage is often two to three times higher than the running wattage. Note these separately.
- Determine simultaneous usage: Consider which appliances will operate concurrently. It’s unlikely you’ll run everything at once. Identify peak usage scenarios—the times when the most appliances are active simultaneously.
- Calculate total wattage: For each peak usage scenario, sum the running wattage of all simultaneously operating appliances. Then, determine the maximum starting wattage needed by adding the starting wattage of all appliances that will be turned on at the same time.
- Add a safety margin: To account for unforeseen demands or future additions, add at least 20% to your total wattage. This ensures sufficient capacity.
- Select a generator: Choose a generator with a running wattage rating at least equal to your calculated total wattage (including the safety margin) and a starting wattage rating capable of handling the maximum starting wattage of your peak load.
Sample Calculation
Let’s consider a hypothetical off-grid household:
| Appliance | Running Wattage (W) | Starting Wattage (W) |
|---|---|---|
