How do you go about choosing the right generator? With load shedding still a very real risk in South Africa, finding the right power generators has become more important than ever. Generators used in a residential building are very different to those used in commercial buildings. The simplest way to determine the best generator size and capacity is to first consider your requirements and power usage on a day to day basis. Just taking size into account, generators typically come in three sizes – small (2kW to 7kW), medium (8kW to 20kW), and large (20kW to 40kW). The size of the generator will come down to the type of building and the average power needs.
There are a few other things that you will need to consider, too. In this short guide, we share some advice on how to select the right power generators for your specific type of building so that you can avoid loss of power in the event of scheduled or unscheduled power cuts.
How to Go About Choosing the Right Generators
Wondering which generator is the best choice for your building? Here are some of the things to consider when choosing power generators.
Smaller kVH generators are best suited for residential buildings. Backup or standby generators for houses are usually smaller and often portable. They are designed to provide power for light-to-moderate usage of various appliances that residential property would require. To determine the exact size, you would need to think about the items in your home that require the most amount of electricity. It’s best to consider the startup current as well as running power to make sure that larger items such as pool pumps do not overload the system when starting up.
Loads you will need to consider powering with your generator could including anything from lighting in kitchens, bathrooms, living rooms, bedrooms, and other rooms to plug points for appliances and devices, larger kitchen appliances such as fridges and freezers, smaller appliances such as kettles and microwaves, televisions and any related appliances, garage door openers, computers, and security systems such as alarms, electric fencing, and outdoor lighting.
Industrial & Commercial Buildings
For most commercial and industrial buildings, whether factories or retail outlets or businesses, larger generators are often a better solution. You will need to be able to fully power your business premises, store or commercial site in the event of a power cut. You will also need to run continuously until power returns. These generators are larger, with features such as automatic operation. This means that generators kick in as soon as the power goes out; shutting down once the power comes back on again. For any type of business, this is crucial to avoid downtime. If there are any gaps between power going out and generators going on, computers, security, lighting, and industrial machines run the risk of not running, which can cause major problems.
Although generators can be used to power the entire building, they can also be used for a single purpose. For example, standby generators could be used specifically for elevators, fire safety systems, emergency lighting, sump pumps or other essential services that cannot risk being offline at any point. For these systems, a large generator of at least 100kW is recommended. Smaller buildings may have different requirements depending on requirements and daily power usage. Smaller retail buildings may only need to power appliances and machines such as computers, security systems, and lighting, and may not require the same level of power as a large-scale factory, for example.
