What Is a Home Generator? Do You Even Need One?

Home generators supply power to a home in a variety of ways. The best home standby generators will give you some flexibility in how that power is generated, but still give you enough power to meet the unique demands that you have. You provide the generator with a fuel source, turn it on, and it begins producing electrical currents that you use through one of its receptacles.

Models are typically measured in the amount of watts they produced. A 600 watt unit, for example, won’t be able to run any of your major appliances when the power goes out, but could provide some lighting and run a small appliance, like a rice cooker, if necessary. On the other end of the spectrum, a 20,000 watt unit can run every major appliance your home has and still have room left over for an air conditioner or two!

The question that must be answered is this: what does your home need if the power goes out for more than 24 hours? You could pack your refrigerator with ice and bucket flush your toilets, but what if that power outage goes to 48 hours? Or lasts even longer? Having a top rated generator supplying power to a sump pump, refrigerator, or a furnace can seem like a luxury when everyone else is struggling without any power at all.

If you live in a single family home, then a home generator might not seem necessary, but it should be included with your emergency plans for added comfort and safety. Apartment or flat residents can also benefit from these reviews, however, thanks to the invention of solar power generation.

Is It Possible to Find the Best Model for Me?

For many home owners, a full 20,000 watt home generator is a little excessive. Although it would be nice to have all of the appliances working during an emergency, there’s one little cost that can’t be overlooked: fueling. High powered models, especially standby generators, can use a lot of fuel when they are working at full capacity. It’s nice to have the extra power, but depending on local rates, you could be spending $30-$40 per day to run the generator – and that’s the low estimate! That’s why many home owners choose a mid-range option that is between 4000-9000 watts.

In this range, you have a wide variety of selection to find the best model that works for you. Some generators are portable or come with wheel kits so you can transport the generator around your property to where it is needed. You get enough power to run 1-3 major appliances, have lighting, and be able to maintain a reasonable lifestyle while the utilities are working to restore power.

One commonly overlooked item in the home generator conversation, however, is the electronic equipment that you have. Generators can produce a high amount of harmonics and although that doesn’t usually bother an older style television set or refrigerator, it can bother your computer, router, and other sensitive electronics. If having power for these electronics is important for your household, then you’ll need to look for the best home inverter generators to have those needs effectively met.

How Do Wholes House Models Work?

To answer this question, the different styles of home generators must be looked at individually through our reviews so that you can see their full functionality. In basic terms, however, you can expect something similar to what is described below.

  • Portable generators. These generators come in a power range of 600-9000 watts in most instances and run on gasoline, propane, or natural gas. When you provide the generator with fuel and turn it on, you will receive power at the receptacles that are on the machine. You’ll need to run extension cords of a commercial grade from the receptacle to your appliances directly in order to get power.
  • Standby generators. These generators sit outside of the home and will hook into the actual electrical grid that the home has. This might happen inside or outside depending on the design and ratings of the generator. They hook into an existing fuel source that is typically propane or natural gas and once started, will monitor the electrical supply to a home. If it is interrupted, the standby generator kicks in and supplies power.
  • Solar generators. For those living in rental homes, an apartment, or a flat, solar generators are often the best to use. They don’t violate a lease in most instances and in return can provide generally up to 2000 watts of power. They charge a battery in the generator in most instances that is then used when the power is out. Look for daylight panels instead of direct sun panels to receive the best results in this category.

What Are the Prices of the Best Units Today?

As you will see in our home generator reviews, the prices of different designs can vary a lot based on the features of the unit. That is why it is critically important to evaluate your needs first! When you can find a generator that meets your specific needs, then you’ll be able to save money by not paying for features you don’t need!

The average price for a home generator is about $600 on Amazon right now. Lower watt generators can be about 50% of this cost in some instances. High watt standby generators typically cost more than $2,000, however, and some models are priced above $5,000.

    Need to know if my home needs a whole home generator and what are the advantages of having one versus a portable 5500 generator.

      For a solar generator to power a refrigerator/freezer, the primary consideration is the starting wattage which is required. Running wattage is also a consideration, but starting the motor of any appliance requires more energy than running it after it is started. This particular appliance has some unique challenges which must be met.

      For a standard sized refrigerator/freezer combination that you could find in the $500-$700 range on Amazon or your local retailer, the running wattage required for it would be 700 watts. To make sure the refrigerator would remain powered, however, you would need to have a solar generator that could handle a surge wattage of 2,200 watts at minimum.

      Larger refrigerators may have a running wattage of up to 1,200 watts. As a general rule of thumb, the surge wattage is a factor multiplied by 3, so the surge wattage on the largest models on the market today could be up to 3,600 watts.

      If the appliance is Energy Star rated with 5 stars, then it may require as few as 1,200 starting watts and 200 running watts.

      Why is the surge wattage so much higher? It is because this is the amount of power that is required to actually start the motor of the refrigerator/freezer after the power goes out. The nature of this appliance’s motor makes it one of the most power-hungry appliances that are in your home.

      You also have the collection of solar energy to consider as well. Many solar powered generators today come with a 40w charging panel. You would need to combine several charging panels to connect with your generator to have an ongoing solution that could remain off-the-grid. Otherwise you would get about 1 hour of run-time from a week’s worth of solar energy.

      Our recommendation would be to purchase a solar panel starter kit such as this one.

      Those panels would allow for up to 400 watts of additional of charging energy to be funneled into a high capacity solar generator such as this one.

      The good news is that a solar generator of this size would also be able to run most other appliances in a home if they were used individually. Only a clothes dryer (7000 starting watts) and a hot water heater (5000 starting watts) require more starting wattage than the average refrigerator/freezer.

    Just finished having a 22kw generac whole house generator connected. 2 days later, the rest of the neighborhood lost power. We were without power for 15 seconds. The rest of the neighborhood was without power for 30 hours. My only complaint was our neighbor complaining that it was loud. I beg to differ. I couldn’t hear anything except our TV. :)..We are very happy.

      I bet you found it well and truly worth the investment after that 30 hour blackout! No power for that long would have caused a lot of issues for your neighbours in terms of lost food from refrigerators, hassles with cell phone charging, etc.
