Generators we work on in Hatfield
High-rise student residences: ATS and changeover problems
Standby sets on parking levels carrying lifts, access control and passage lights for hundreds of rooms.
Walk-up residences and flats: Residential generator services
Smaller diesel sets in yards and side passages keeping gates, lights and Wi-Fi going through an evening slot.
Embassies and diplomatic offices: Standby generators
Standby sets behind security that must start on every outage and hold the load for offices, communications and the guardhouse.
Office buildings: Voltage problems
Landlord sets carrying lifts, tenants’ floors and server cupboards behind a UPS, where steady voltage matters.
Restaurants and shops on Burnett Street: Commercial generator services
Sets behind kitchens and stores around Hatfield Plaza and Burnett Street, carrying cold rooms, extraction and tills through each slot.
University and school facilities: Diesel generators
Sets at teaching, sports and school buildings that stand for weeks, then must carry lights and IT at once.
Repairs
Generator faults we fix in Hatfield
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.
AVR and voltage faults: Voltage problems
Low, high or swinging voltage from the AVR, exciter or rotating diodes.
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.
Control panel errors: Control panel repairs
Alarms, lockouts and wiring faults on DSE, ComAp, SmartGen and other controllers.
Student housing
One set for a whole residence
A high-rise residence hangs hundreds of rooms on one standby set, usually on the parking level below. When the mains fails, every lift, light and access reader moves across together, and a slow changeover or tired battery leaves residents in dark stairwells or a stopped lift.
Load is the other trap. A set sized for passages and lifts can find kettles and heaters in every room switched onto it, and the breaker trips or the voltage sags. We measure what it really carries before blaming the generator.
- Changeover and lift recovery tested with the manager
- Load measured against the set’s rating
- Basement ventilation and exhaust checked
- The set left in automatic

Response
On site in Hatfield in 1–2 hours
Technicians on site in 1–2 hours, 24/7. Hatfield sits at the Pretoria end of the Gautrain line from Johannesburg, with the CBD, Brooklyn and Waterkloof, Menlyn and Pretoria Moot around it, so a technician comes in from whichever side is clear. Tell us the building, who holds the plant-room keys and what security asks of contractors.
While you wait, check the fuel gauge, emergency stop and main breaker, and note the controller screen; leave the changeover panel and fuel lines to the technician. If someone is stuck in a lift, call the lift company too. WhatsApp a photo of the screen and nameplate; see emergency generator repair.
Every make
Every make, from residence standby sets to kitchen portables
We Service & Repair All Generator Brands. In Hatfield’s residences, offices and missions that mostly means diesel sets on Cummins, Perkins or Volvo Penta engines with Stamford or Leroy-Somer alternators and Deep Sea Electronics or ComAp controllers. Walk-ups and restaurants run smaller silent diesels from Kipor, Bundu Power or Pramac on SmartGen modules, and some shops keep a Honda or Yamaha petrol portable. See our brand pages.
Prevention
Repeat callouts in Hatfield, and how servicing ends them
A second callout usually has the first cause still in place: a new residence battery dies if nobody meters the charger that flattened it, fresh filters block if water sits in the base tank, and a kitchen set overheats while its radiator stays packed with grease.
Servicing deals with those causes. Our Hatfield generator service and maintenance page covers the visit at a residence, mission, office or restaurant, and the plans landlords use. Generator repairs explains how we trace a fault; we also cover the Pretoria CBD, Brooklyn and Waterkloof, Menlyn and the rest of Pretoria.

FAQ
Frequently asked questions
The generator at our student residence runs, but the lifts and rooms stay dark. Why?
Usually the changeover: the transfer switch, its mains sensing or the controller signal that tells it to move the load. That is a technician’s job, so please do not force the panel; send a photo of the controller screen.
Can you repair a generator at an embassy or diplomatic office?
Yes, by arrangement. Tell us what the mission’s security asks of contractors, such as names and ID numbers in advance, and we work within the visit times it sets, after hours where needed.
Our restaurant’s set trips when the kitchen and cold rooms are both on it. Is it faulty?
Not always. We measure the load against the rating first: if the set is too small, staggering loads or a larger set is the answer. Our kVA sizing guide explains the sums.
Is it safe to run a petrol portable behind our shop during load shedding?
Outdoors, yes, well away from doors and windows because of carbon monoxide, and through extension leads rated for the load. Never plug it into a wall socket to back-feed the shop; fitting a changeover switch is a technician’s job.
