With a generator rated at 5,000 to 7,500 watts, you can run even the most critical household equipment, including things such as refrigerator, freezer, well pump, and lighting circuits. A 7500-running watt generator can run all these appliances at once. For RV, a 3000-4000-watt generator will work great.
How do I calculate what size generator I need?
- Full load kW = Total amps x supply voltage / 1,000.
- Reserve capacity = Full load kW x 0.25.
- For 100 percent power, generator size = Full load kW + reserve capacity.
- Retail application: 50 kW + 10 watts per square foot.
- Other commercial application: 50 kW + 5 watts per square foot.
