Once the power goes off, it takes 10 seconds for the Generac 7043 to take over the electricity supply and it manages to remain as quiet as possible, at 66 dB.

It’s an all-purpose model that can power anything from lights, even halogen work lights, to all-size appliances, power tools, sump pumps, and well pumps. It can be fueled with natural gas or liquid propane and you also have the option to buy a battery that can be used in case you run out of fuel.

It’s also a bigger size whole-house model that can be used to power anything from lights, excluding halogen, to power tools, small and large appliances, and water pumps. The 999cc engine designed by OEM Branded takes its power from natural gas or liquid propane, making it suitable for any home.

The start is electric so it doesn’t take long for it to turn on when needed, requiring approximately 10 seconds to respond to a blackout. Among the features included, we remind the Low Oil Shutdown that prevents a malfunction in case the oil level drops too low and the Overload Protection that also ensures a smooth operation in safe conditions.

It is also equipped with a Quiet-Test mode that turns the engine to a lower RPM in order to reduce the noise and the fuel consumption. It complies with all safety standards like CARB and EPA and it comes with a 5-year warranty so that you can enjoy a worry-free performance.

It responds in seconds and it’s strong enough to sustain the entire house and all the appliances in it. Whether you choose to power it with natural gas or propane, it’s more economical than other competitors.

3. Kohler 14RESAL-200SELS

This non-portable generator is also a very powerful unit that can handle whole-house electricity supplying. It features a smaller 725cc engine and is an air-cooled model so it’s not as reliable as the first two one in sustaining high-voltage devices. Still, it can be used to power the lights, mobile devices, and household appliances. It isn’t suitable for powerful water pumps or power tools.

Made of composite, it is resistant to bad weather and it will work without issues even if it’s raining or snowing. With the majority of portable models, you have to wait until the rain stops to get it started without risking a fire hazard. You can choose between a 100 and a 200-Amp version, both with a 14000 wattage and the option of either natural gas or propane fueling.

For safety reasons, it is equipped with two essential features, namely the Low Oil Shutdown and the Overload Protection. It also features an Hour Meter that counts the hours since the last oil change, thus, making maintenance easier. The standard 5-year warranty is also available for it.

  • Weather resistant housing
  • Safety features to prevent damage
  • High wattage for maximum efficiency
  • Long warranty
  • Small engine

It is great for whole-house use and it offers great results regardless the weather sue to the solid construction makes it resistant to moisture. You won’t even know it’s on because it’s not noisier than other models we have reviewed. Although the engine is smaller in capacity, it has a generous wattage that ensures it will successfully handle the entire house. All in all, it’s a very reliable and durable choice, especially since it’s covered by a long warranty.

4. Briggs & Stratton 40449

You’ve probably heard about Briggs & Stratton so you are familiar with how popular they are and how qualitative their products are. The generators they offer are varied and we have chosen the 40449 because it’s one of the customers’ favorite. It’s a more compact version that weighs only 272 pounds, which is not much considering it’s made of steel and comparing it to other similar models. It’s a lower wattage model that only boasts 10000 watts but it manages to handle high-demand appliances that require plenty of energy.

Its compact size makes it more advantageous for people with limited space and it doesn’t sacrifice performance in any way. The automatic transfer switch is a patented 100-Amp Symphony II that offers more power so that it will be able to sustain large appliances while also ensuring enough power for the small ones. The 570cc engine can be powered by natural gas if you have a local supply line or propane liquid that you need to supply yourself. Take note that the response time is a little longer than in previous models, taking it 20 seconds to detect the power outage and start providing electricity.

Although it isn’t equipped with a Low Oil Shutdown feature, it has an hour meter that lets you know when it’s time to change the oil and also an Overload Protection for safe functioning. It also offers the option of remote monitoring thanks to the built-in mechanism. The warranty is the standard 5-year found in most models.

  • Powerful enough for the entire house
  • Compact size for small spaces
  • Safe operating
  • Comprehensive warranty
  • Longer response time

Coming from such a reputable manufacturer, we couldn’t expect less from this product. It relies on a powerful engine that ensures power for the entire house and it offers two fuel options. It’s equipped with safety features that help you handle its maintenance and avoid damage that could void the warranty. However, keep in mind that it’s a little noisy and it takes almost the double for it to respond to a power outage.

5. Champion 100177

We continue the list with this model from Champion that can deliver great power thanks to the OEM Branded engine. It is suitable for indoor and outdoor electric equipment and it adapts to both 120 and 240V current. Whether you have a natural gas line or you decide to power it with propane, it will be very easy to install and connect to your home’s electric grid. According to the manufacturer’s specifications, it takes only 1 second for it to respond to a power outage, so the result will be practically instant.

It also boasts an electric start that is able to turn the unit on even in below 0 temperature conditions so you can use it all year round, even in the harshest winters. Another advantage of this product is the low operating sound that barely reaches 60 dB, which is the lowest in its class. To end the list of qualities, we mention that the warranty is a generous 10-year period that will ensure extended problem-free use.

  • Powerful enough for the entire house

  • Is very silent

  • Not powerful enough for large tools

This one we picked seemed like a very good choice at a very reasonable price. However, it’s not as powerful and reliable as the previous ones and it can’t handle items like tools but it works for lights and home appliances. The small engine is responsible for the lack of power, as well as the low wattage. A good thing about it is the instant response to a power failure, followed by a silent operating.

What To Know Before You Purchase

Having one of these in your home can be extremely helpful in certain situations. Especially if you live in the states where winter isn’t so pleasing. In other words, this is one of the best protection to have against power lines getting cut off. This is why the majority of them are on the more expensive spectrum due to the companies taking advantage of its usefulness. Thus, there are certain things that you should know before you decide on whatever model you find the most suitable for your home and your needs.

  • Directly connected to the electric box – The reason we strongly recommend this type of generator is that you will never be left without power. If it’s directly connected to a power source, you can rely on it for many days. Kiss goodbye to the days where you had to survive in the dark because if you purchase whatever model, you will never be left without power. This is because, as soon as the power from the power line cuts off, it will start automatically without too much effort on your part. Nonetheless, please remember to connect it to a fuel source. It doesn’t matter if it’s gas, propane or diesel.
  • It varies between the wattage powers – It’s general knowledge that an average unit of 25 kilowatts is more than enough for a small house or an apartment. Don’t worry as you won’t have to turn off other appliances to ensure its functionality. You can use the microwave simultaneously. Whatever the size of your house is, you should know that a generator is enough. You do not have to worry that you have to conserve energy because this isn’t the case. Decide which model is suitable for your home and go ahead purchasing. Your home will have electricity whatever happens to the power lines or grid.
  • It’s noisy – This is the main disadvantage of them. This is because it doesn’t matter how small the unit is, it will still make noise whilst it’s running. The people that have already bought it describe it to be something like a lawn mower in use. Nonetheless, if you choose a more powerful machine you will notice that the sound is isolated and it will sound just the same as a smaller model. This is why you need to take into consideration if you can manage with the sound for numerous days. However, you can solve this problem by placing it somehow far from the areas where you are lounging.
  • Extra costs – If you are not a plumber, it’s inevitable that you will spend additional money for the electrician’s work or other technicians. As well as, you may also need a contractor because the units are all bulky so it will take up a lot of space. In addition to this, you may also be required to have a building permit as well as tax. As well as, you will have some people checking it out because it requires safety inspections. They all cost.

Installation Inconveniences

Although they offer the huge benefit of supplying your home with electricity in case of a power shortage, standby generators also hide some drawbacks when it comes to installation. In order to overcome them, you must first learn more about which are the inconveniences you could experience when trying to set up one at home.

  • High noise level

    In some areas, it could be forbidden to install one because of the noise regulations that specify no household device should be louder than 60 dB. Measuring the noise level of each product is made at a 25-feet distance so the actual noise could be louder right next to it.

  • Space limitations

    Another regulation is related to the distance required between a generator and a building or flammable materials. Therefore, keep in mind to place it at least 5 feet away from the house and 5 feet away from items that could catch on fire. Also, the fuel tank should be carefully placed to avoid a fire hazard.

  • Difficult to install

    When it comes to dealing with a natural gas line, it’s best to hire a professional that is familiar with all the components and installation processes of an electricity generator. The gas pressure is also vital in installing it properly so make sure the person you hire knows which are the specifications of the local gas supply.

  • Costly

    If you consider getting one at home, be prepared for high costs that imply not only the purchase cost but also the additional electrical and plumbing work as well as future maintenance. The highest quality units can cost between $5,000 and $20,000 only for purchase so the investment is not to overlook.

  • Hard to maintain

    Speaking of maintenance, not only the costs are a headache but also the task itself. You will have to change the oil periodically, replace damaged motor components, and be very careful how you use it to prevent irreparable damage.
