Generators we work on in Sandton
Office towers in the CBD: Control panel repairs
Large standby systems, often paralleled on a common busbar and tied into the building management system.
Hotels and the Convention Centre precinct: ATS and changeover problems
Sites that trade through the night, where guests notice a failed changeover at once.
Banks, head offices and server rooms: Standby generators
Around the JSE in Sandown a UPS bridges the gap until the set starts, settles and takes the load.
Shopping centres and restaurants: Commercial generator services
Sandton City, Nelson Mandela Square and the Hyde Park and Morningside centres, where cold rooms and tills ride on the standby supply.
Medical rooms: Voltage problems
Consulting rooms and day clinics in Morningside and Illovo that need stable voltage and refrigeration.
Large homes and cluster complexes: Residential generator services
Silent diesel and gas standby sets in Sandhurst, Hyde Park and Inanda, and shared sets at complex gates.
Repairs
Generator faults we fix in Sandton
ATS and changeover problems
The set runs but the building stays dark, or the load never returns to the mains.
Battery and charging faults: Battery not charging
Chargers, charge alternators and batteries that cannot crank the set when the mains fails.
Control panel errors: Control panel repairs
Alarms, lockouts and wiring faults on DSE, ComAp, SmartGen and other controllers.
Fuel and injector faults: Fuel system repairs
Contaminated diesel, blocked filters, air in the lines, lift pumps and injectors.
Overheating
Shutdowns from blocked radiators, failed fans, thermostats and coolant leaks.
AVR and voltage faults: Voltage problems
Low, high or swinging voltage from the AVR, exciter or rotating diodes.
Commercial buildings
Working in Sandton buildings
In Sandton’s towers and hotels the generators sit in basement plant rooms, on parking levels or on rooftops, behind layers of security. Building management needs notice before any test that moves the building onto generator power, so we book the hours the building allows and leave the set in automatic.
Paralleled systems are repaired as a whole as well as set by set: synchronising, load sharing and the breaker sequence, because a fault there stops the system taking the load when every engine is healthy. We diagnose and set up the DSE and ComAp modules on these systems.
- Access, permits and inductions arranged through building management
- Load-transfer tests timed with the building
- Synchronising, load sharing and breaker control checked
- The set returned to automatic before we leave
Response
On site in Sandton in 1–2 hours
Technicians on site in 1–2 hours, 24/7. Sandton sits between the M1 on its eastern side, Rivonia Road and Grayston Drive through the middle and William Nicol Drive to the west, so a technician reaches the CBD, Morningside or Hyde Park from any direction. Tell us the building, the parking height limit and who clears contractors.
While you wait, note what the controller shows and stop pressing start on a set that cranks and dies: a battery with something left beats a flat one. WhatsApp a photo of the controller and the nameplate and the likely parts come with the first visit; emergency generator repair explains an after-hours call.
Every make
The generator makes we repair in Sandton
We Service & Repair All Generator Brands. In Sandton’s towers that mostly means large diesel sets on Cummins, Perkins, Volvo Penta or MTU engines with Stamford or Leroy-Somer alternators and Deep Sea Electronics or ComAp controllers; in the homes, silent diesel sets of every make and gas standby units on LPG. Work on a gas unit’s supply is for a registered gas installer. See gas generators and our brand pages.
Prevention
Why Sandton sets fail twice
The same buildings call us back for the same faults when nothing changes after the repair: a new battery goes flat if the charger that killed it stays, and a day tank runs dry again if the transfer pump is not checked. A repair fixes the fault in front of us; the report says what else we found.
Regular servicing stops the repeat. Our Sandton generator service and maintenance page covers what a service in a tower, a hotel or a Sandhurst home includes, how often a set that runs through every load-shedding slot needs one, and the plans we run for building managers. Generator repairs explains how we find a fault; we also work in neighbouring Bryanston, Rivonia and Rosebank, and across Sandton.

FAQ
Frequently asked questions
Can you repair the generator in our Sandton office building after hours?
Yes. We work 24/7, so repairs and load-transfer tests can be done before or after business hours or at weekends, by arrangement with building management.
Our building has two generators that run together. Can you work on them?
Yes. Paralleled sets are checked as a system, synchronising, load sharing and breaker control included, as well as each engine and alternator. Tell us the controller make when you book.
Do you repair home standby generators in Sandhurst, Hyde Park and Morningside?
Yes: silent diesel and gas sets, automatic changeovers, battery chargers and controllers, including shared sets at cluster-complex gates. See home generator services.
