Reviews of the Best Home Standby Generators of 2018

1. Generac 7043 Guardian Series

Generac is a company that designs the most reliable and resistant standby generators and their 7043 Guardian Series model can sustain the entire house without any effort. It’s a powerful 16000-watts machine that can be used on a 120/240 single phase current. Thanks to the True Power technology and the powerful G-Force engine, it delivers top power quality that ensures the safe operating of your precious appliances. It comes equipped with a 200Amp NEMA 3 automatic transfer switch that is compatible with indoor and outdoor operating.

The exterior is made of a very resistant aluminum coated with a weatherproof paint that guarantees problem-free installation, operating and maintenance. 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. There are many features included like the Low Oil Shutdown that monitors the oil level and the Quiet-Test that makes it run in a more silent and fuel-efficient mode.

It’s an all-purpose generator 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. The manufacturer offers a generous 5-year warranty so you can be sure that maintenance and troubleshooting will not become an issue.

PROS

CONS

Very quiet even at high speeds
Fast response when the power goes out

Battery operating choice
Safety features included

VERDICT

When you run out of power, this is the generator you need to rely on. It’s effective, it restores the power in mere seconds, and it doesn’t make a lot of noise that could disturb your sleep. Also, it’s incredibly sturdy and resistant to bad weather so it will provide worry-free operating throughout the year. Thanks to the safety features it’s packed with, it will prevent self-damage so you can rest assured.


2. Generac 7037 Guardian Series

The second best product is another model from Generac, namely the 7037, that is a more powerful version of 22000 watts. 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.

The generator 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.

PROS

CONS

It doesn’t make too much noise
Turns on on its own
Safety features to prevent overexertion
Can be used for the entire house
Generous warranty period

VERDICT

Similar to the previous model, this one provides power for the entire house whenever there is an outage. This one is actually more powerful and is equipped with the same useful features that not only make it easy to install and use but also very prompt. 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 generators, 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 this high-quality home standby generator.

PROS

CONS

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

VERDICT

This generator 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 for the generator 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.

PROS

CONS

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

VERDICT

Coming from such a reputable manufacturer, we couldn’t expect less from this home generator. 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 of the greatest power generators 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, the generator 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. With features like Automatic Voltage Regulation and Low Oil Shutdown, you can be sure that malfunctions will be a rarity.

PROS

CONS

Powerful enough for the entire house It has a very small engine
It has the shortest response time Not powerful enough for large tools
Is very silent
Comes with a very long warranty

VERDICT

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.
