Servicing and maintenance on all makes of generators

Any generator set used for emergency or primary power supply must have periodic service and maintenance performed on it. Setting up a planned maintenance schedule, and performing all associated testing will insure generator availability on demand. The possibility of generator failures escalate when service and maintenance checks are not done.

Diesel refilling

Generator refuelling services from Generator Boys
Whether you own a small business or a large company, it is vitally important to have a back-up power system in place to take over during the event of a power outage.


24 hour call out service



24/7 Emergency Generator Service in Gauteng
As a complete maintenance solution, generator-boys has technicians on call 24 hours a day, seven days a week, 365 days a year to assist you with emergency generator service throughout Gauteng.



On site load testing of generators



The purpose of a generator is to offer a reliable source of power to your facility or commercial operation throughout an emergency, when power from the grid is unexpectedly lost, or is temporarily unavailable in your environment. In the event of a power failure, you should have peace of mind that your backup power source will immediately start on demand; But what happens when the power goes out and your genset does not function as expected? The result can often be costly and sometimes catastrophic.


Fault finding on generators.

Battery failure
The single most frequent service call for generator failure is related to battery failure. Eighty percent of all battery failure is related to sulphation build-up — the accumulation of lead sulphates on the plates of lead-acid batteries.


Generator Boys offers a large variety of services to both industrial companies and the general public. We install new generators and also offer service and maintenance on all makes of generators. Maintenance contracts are also available depending on how often your generator is used. Our 24 hour call out service will make sure that your generators keep running, even when they are working under pressure. If there is a problem with your generator, we can do a fault finding analysis on all makes of generators. We can also refill diesel generators. For heavy mining applications, we offer special voltage generators to withstand the large and constant power requirements of a mining operation. Our exhaust systems are tailor made to suit your generator and environment, whether for residential or industrial use.



The 40 Kva is ideal for residential use since it is nearly silent when used and will not disturb your neighbours, while producing a sufficient amount of power. For companies with large power requirements, as well as the need for a constant power source, our stand-by generators are ideal to provide the required power source time and time again for these demanding situations. Our high quality control panels will ensure that you are always in charge. We also rig and move generators. We manufacture a wide range of products such as:


  • Load banks
  • Dummy loads
  • Electrical equipment

With competitive prices, friendly and professional service, your old or new generator will have a longer life.

Diesel Engine Generators

What is a Diesel Engine Generator?

A diesel engine generator is known as the combination of a diesel engine with an electric generator (often an alternator) used to generate electrical energy. This is a specific case of diesel engine-generator. A diesel engine generator is usually designed to run on fuel, but some types of generators are adapted for other liquid fuels or natural gas.

Diesel engine generator sets are used to power places without connection to a power grid, or as an emergency power-supply if the power grid fails. A diesel engine generator can also be used for more complex applications like peak-lopping, grid support and export to the power grid.

Diesel engine generator sizes:

Diesel engine generator sets are selected based on their electrical load that they are intended to supply. These electrical load's characteristics such as kWe, kVA, var, harmonic content, surge currents (e.g.motor starting current) and non-linear loads. The diesel engine generator's expected duty (emergency, prime or continuous power) as well as the environmental conditions (altitude, temperature and exhaust emissions regulations) should also be considered.

Genuine Diesel Engine Generators:

Generator Boys uses only genuine brand name Diesel Engines and Alternators with readily available spares in the manufacture of diesel engine generators. With the most current technology we enjoy manufacturing diesel engine generators using the latest Common Rail diesel engines, utilizing all the advanced features for engine control and protection.
