Value for money is important when choosing a standby generator. And while there is actually no such thing as a cheap standby generator per se, it is very much the case that some of the best standby generator units are more or less expensive than others, and that even the best value units are attractive investments.

Innovations in power backup technology and unit construction of the past few years means that when you shop among the most renowned brands, you are not sacrificing an awful lot of features as against the most expensive in those lines. Across the board, the main factor is the ‘built to last’ factor—choosing a cheap standby generator from brands such as Generace, Kohler and Briggs & Stratton means that you will be buying a product that will endure.

At $2064, the Briggs & Stratton 40445 is the least expensive and best value standby generator unit that we reviewed. The Briggs & Stratton 40445 is an 8kw unit that is renowned for its versatility and adaptability, and is perfectly suitable if you only want to provide a backup power source for your home’s basic circuits, covering lights & appliances including refrigerators and televisions and more.

It’s also suitable for owners of smaller properties, as it can be placed as close to your house as 18″, and best of all, it has a 50-amp transfer switch enabling it to automatically supply power to limited circuits in the event of a disruption. This is exactly the kind of machine that has made the Briggs & Stratton name—quality construction, powerful operation, reliability, user-friendliness and adaptability to a range of circumstances.

Leaping up to the $2,999 price bracket is the 40450 generator from the same Briggs & Stratton brand. It’s essentially a more powerful and robust version of the 40445, producing 10kw of power, and also equipped with a 200-amp automatic transfer switch that will detect a power outage and automatically start supplying the power to your home.

It’s a little bit louder than the 40445, but given its transfer switch functionality—which will also automatically deactivate the generator when the mains power is reconnected—and its five-year limited warranty to cover parts and labour, the Briggs & Stratton 40450 offers decent return on investment.
