In this day and age, as you’ll know, our homes are very much energy-dependant to allow them and their components to function as they should. Those components being all of your appliances including your fridge, freezer, washing machine, etc. Whilst this is all fairly obvious, you may not have considered that a loss of power to your home for an extended period of time really could be quite a big deal, and quite a bad one at that.

In particular, if you have an electric car or mode of transport, the last thing you would want is to be left in your powerless home! Whole house generators are also known as standby generators, or a full house generator. This post considers some of the best whole house generators, including what to look for when it comes to the cost of a whole house generator as well as whole house generator sizing. There are quite a few great options available for use as standby/full house generators. Hopefully after this read, you’ll know what will work best for you.

Generac 7043 Home Standby Generator

The Generac 7043 is 22 kW generator. Due it’s massive power potential and long runtime capabilities, it makes the perfect whole house generator.

The 7043 from Generac can run well on both propane and natural gas. At peak power, it will return 22,000 watts of power if it’s running on propane, and a very respectable 19,500 watts if it’s burning natural gas.

This Generac has a full remote monitoring system built in, ideal if it truly is bad weather that’s keeping you indoors and your power off! The system allows you to check the status of the 7043 from any device that is internet-enabled. This gives you near enough all of the information that you’d need to know about your Generac 22kW, including fuel levels, runtime remaining, and current power output.

Generac have installed their G-Force engine into this unit.  The G-Force engines are pressure lubricated, and are more than capable of handling the large power demands that an entire house would place on it.

There’s also a NEMA 3 smart transfer switch built into this Generac that’s suitable for both indoor and outdoor use. In case you’re unsure, these switches are designed to manage multiple loads on the generator with ease. This is great value too, considering the switches are sold individually.

As well as the monitoring system, the Generac 22kW whole house generator comes with a display that can be configurated to many languages that displays various points of information such as the power level, and how long you should leave your generator until its next service – all of this helps to make sure you keep your Generac in as good condition as you can!

Even though this generator puts out a huge amount of power, it’s not a massive unstable current like you might think! Due to inverter-like technology that it has installed as well as the switch, it’s more than capable of dividing up its power between any appliances that are requesting it. Any power that it gives out will be suitable for any appliance.

Key Features

  • Minimal maintenance since it has a “self-testing mode” installed, making sure that al components are operating as they should
  • Uses True Power technology, which means that like smaller inverter generators, this Generac 7043 is able to deliver power that’s safe for smaller more sensitive electronics as well as larger ones.
  • Screen display that makes it easy to see when there’s anything that might require your attention. It also give you advice on service intervals and caring for your generator.
  • RhinoCoat power-coated aluminium casing – the 7043 is ahead in the fight against the elements and rust.
  • Peak power of 22,000 watts


  • Fairly frequent maintenance required
  • Wiring can be fiddly to reach

Champion Power Equipment 100294 14KW Home Standby Generator

In terms of what you might expect from a whole house generator, the Champion 100294 is likely to have all of these covered and a considerable amount more. It makes itself clear in the market with its well thought out design and amazing looks.
