1. What is a Generator Size for Camper Calculator?

Definition: This calculator estimates the required generator size (in kW) for a camper based on the total electrical load and a safety factor.

Purpose: It helps RV owners and campers determine the appropriate generator capacity to power all their electrical appliances.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Generator size (kilowatts)
• \( \sum P_{load} \) — Total electrical load (watts)
• \( SF \) — Safety factor (typically 1.25 for campers)

Explanation: The total wattage is converted to kilowatts (divided by 1000) then multiplied by a safety factor to account for startup surges and future needs.

3. Importance of Proper Generator Sizing

Details: Correct generator sizing ensures reliable power supply, prevents overload damage, and improves fuel efficiency.

4. Using the Calculator

Tips: Sum all electrical loads in watts (including lights, appliances, AC units), enter the total, and use the default 1.25 safety factor unless you have specific requirements.

5. Frequently Asked Questions (FAQ)

Q1: What's included in total load calculation?
A: Include all electrical devices - lights, refrigerator, AC, microwave, water pump, electronics, etc.

Q2: Why use a safety factor?
A: It accounts for startup surges (especially for motors) and potential future power needs.

Q3: What's a typical safety factor?
A: 1.25 is common for campers, but you might use 1.5 if you have many motorized devices.

Q4: How do I find my appliances' wattage?
A: Check manufacturer labels or use our Appliance Wattage Calculator tool.

Q5: Should I round up the generator size?
A: Yes, generators come in standard sizes (2kW, 3.5kW, 5kW, etc.) - choose the next available size above your calculation.
