Criteria for Choosing the Best Standby Generators

Power Requirements

Your choice obviously will depend on whether you want a model for powering the entire house or keeping a select few home appliances running. To this end consider the watts of power the machine delivers. If you want a generator to keep your ACs and other high energy demand appliances running simultaneously, then a powerful unit capable of delivering power in the neighbourhoods of 20,000 watts should do the trick.

Performance and Construction Quality

Power requires aside, the quality of the standby generator should supersede all other factors. You don’t want to compromise on quality if you’re a sucker for efficient performance, reliability, clean power, and trouble-free experience.

Similarly, the workmanship should be exceptional. In addition to withstanding chips and abrasions, the model should be resistant to rust and corrosion to provide the user with years of flawless, efficient performance.

Location and Installation

A third essential consideration is the location of the standby generator. The chosen location should allow for hassle-free access for easy and quick maintenance and repair. Additionally, it needs to be adjacent to a source of fuel and the transfer switch.

If that’s not the case, it would be prudent to seek professional assistance to avoid voiding your warranty.

Consider your power requirements before committing your money. It’s pointless investing in a $4000 model you’ll be using once a while for lighting and running the entertainment system.
