Can I Run My Whole House on a 12000 Watt Generator?

A 12,000-watt generator is a powerful option for homeowners seeking reliable backup power. But can it truly run your entire house? The answer depends on your home’s energy demand and the number of appliances you plan to operate during an outage.

At Belmont Generator, we design and manufacture high-quality diesel, gasoline, and natural gas generators that range from portable home units to industrial systems. Let’s break down what a 12,000-watt generator can do — and whether it’s enough for your whole house.

• Refrigerator and freezer

• Lights and fans

• Sump pump and water heater

• Washing machine and dryer (one at a time)
