"I cannot say enough great things about Jamie and the team at Wisconsin Generators LLC. From the very first conversation, Jamie was professional, knowledgeable, and incredibly responsive. He took the time to walk me through all my options, answered every question thoroughly, and made sure I felt confident in the decision we were making. The installation process was seamless. The crew showed up on time, worked efficiently, and treated our property with respect. Their attention to detail and commitment to doing the job right was obvious from start to finish. Everything was clean, organized, and completed exactly as promised. What really sets Jamie apart is his integrity and customer-first approach. There was no pressure just honest recommendations and clear communication. If you’re considering a standby generator, I highly recommend Jamie and Wisconsin Generators LLC. Reliable service, expert installation, and true peace of mind. Five stars all The way!!"

"First, they were recommended to us for the whole house generator by home depot.  We were so happy with the generator that we had him do a bathroom fan at my house and a bathroom fan at my son's house.  I did some checking and that was a reasonable price.  With the work he did, it was more than reasonable.  The job was a little more involved than he thought it would be and he didn't have any problem with any of it.  Without anything to judge the pricing from, other than online and a couple of guys I had come over who weren't on the same page as me, I'd say excellent.  The quality was top of the line.  As soon as he got the generator, he got over here to put it in. As a matter of fact, I am thinking about calling him again for something."

Generator Install questions, answered by experts

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.
