You won’t hear them kick in if they’ve been installed properly, but generators can be found in many office buildings across South Africa. Some offices simply cannot afford to have the power go down at all, while others choose to have backup power for their occupants’ convenience. Either way, with Eskom yet to announce a much-anticipated finishing-off of load shedding, every office building could do with backup power generators in place.

Why backup power for the office?
Ensuring an office building remains connected to electricity means it can remain connected to everything else it needs to operate. With backup power, an office can remain open to the public, keep the lights, power network infrastructure, power computers and other devices, and – most importantly – ensuring the kettle can boil water for coffee! Seriously though, so many issues arise in offices when the power goes out, so an office setting is definitely one of the most important places to have a backup generator.
Questions to ask about office generators
Before setting your mind on the brand, type, or capacity of generator you’d prefer, here are a few questions to ask about your office space:
- Will the generator remain stationary or need to be portable?
- How many appliances, devices and lights need to be run?
- What available space is there to install the generator?
- Which type of fuel should the generator consume? (diesel, gas, petrol)

3 types of generators for offices
Commercial generators are predominantly used as standby, nice-to-haves in office settings. Some industries, however, are required by law to have backup power generation on call at all times.
- Emergency Standby Generators
Emergency standby generator systems automatically kick in when the office experiences power loss due to a power outage. These office generators are required by NFPA code and must provide power to all the building’s safety systems within 10 seconds. These include exit lighting, smoke alarms, fire alarm systems, escalators, elevators, and anything that is absolutely necessary for people inside the building to remain safe or get to safety during life-threatening scenarios. Emergency standby generators must be completely separate and have their own electrical panels, switches, and conduits.
- Legally-Required Generators
These backup generator systems are similar to emergency generator systems, except that they have up to 60 seconds to automatically provide power. Legally-required generators are installed in spaces where backup power is required by law. However, they don’t need to be completely separate systems (like emergency generators). The difference with these systems is that they are not critically needed for office building occupant safety.
- Additional Standby Generators
This is any additional standby generator added to an office building is not required by code. These standby generators can be used to provide power to key equipment and systems that the business may find necessary to continue regular operations when the power cuts. Essentially, these generators can help mitigate profit losses and losses due to downtime. These generators can also help keep air conditioning systems running to provide continued comfort.

A Diesel Generator will produce power by burning diesel fuel, a diesel generator uses a combination of a diesel engine and an electric alternator. This generator converts a portion of chemical energy within the diesel fuel, resulting in a combustion that turns into mechanical energy. These generators are affordable and the recommended choice for residential properties and smaller commercial buildings. If you’re looking for a way to get backup power in the event of blackouts, loadshedding, outages and other power issues, this type of generator can be highly useful. Although solar generators are more eco-friendly at a glance, there are ways that you can make your diesel generator more sustainable. You can choose a modified generator, such as a bio-diesel generator or speak to a generator specialist such as S&A Generators to choose the best option for your needs. So, how does a diesel generator work? You’re about to find out:
Diesel Generator Parts & Process
What should you know if you are considering a diesel generator for your home? For starters, it helps to have an idea of the generator parts and how they work to power your home. Here are some of the most important parts of a generator.
The engine runs on diesel. Similar to very large vehicles such as trucks, the larger the energy source, the more power the engine will produce.
This part converts a mechanical engine into electrical power, using induction. Large magnets are placed around a rotating shaft, windings produce a magnetic field that causes the alternator to turn. Alternators also contain a stator – several coiled bundles of wire packed around the rotor. When the alternator moves the shaft, the rotor moves the magnetic fields across these wires, resulting in an alternating current (AC) power.
The fuel supply includes a tank that holds enough diesel for around 8 to 12hours of power. It can be housed inside or on top of smaller and portable generators or in separate structures for larger units. The fuel also includes pipes that deliver fuel to the engine, a fuel pump, a filter and a valve to prevent overpressure. It also has a return line to redirect the leftover diesel back into the diesel tank to avoid wastage.
Diesel generator engines create a lot of waste heat. This needs to be cooled using coolant fluid. The cooling system helps to avoid overheating by releasing heat into the air or a secondary coolant.
Exhaust gases are produced by all engines. As these gases are toxic, they need to be redirected away from the engine and channelled safely into the air outside.
The engine is lubricated with the help of an oil pump, oil filter and a reservoir. These are attached to the generator engine.
These parts allow the diesel generator to start running. A small electric starter motor, usually powered by a battery(12v-24v), is charged by the generator output or a separate charger.
The generator’s battery is kept constantly charged by an on board smart battery charger. This battery charger is constantly charging the battery at between 13.6v to 27.3v. When the generator is running the DC alternator will take over the charging of the batteries.
Now that you have a better idea of the parts making up this type of generator, the next step is to get the generator installed. S&A Generators offers a range of services designed to help you get your generator set up and running, along with maintenance and other solutions.

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.
What size generator is needed to power a house?
