Generators we work on in Ga-Rankuwa and Mabopane
Homes in all three towns: Portable and inverter generators
Petrol and inverter portables, or a small diesel on wheels, kept for lights, phones, the fridge and the TV.
Shops and small businesses: Voltage problems
Fridges, tills and lights on one set, where a compressor starting can pull the output down.
Malls and larger stores: ATS and changeover problems
Fixed standby sets with an automatic changeover, which must take the load the moment the mains fails.
Schools and clinics: Battery not charging
Diesel sets that stand idle for weeks, so a flat battery or stale fuel shows up only in the outage.
Industrial Park factories: Industrial generator services
Three-phase sets behind machines, compressors and workshops in the refurbished units, often loaded unevenly across phases.
The hospital and university precinct
Their main plant is usually under state contracts; we quote for breakdown work when a facilities team asks.
Repairs
Generator faults we fix in Ga-Rankuwa and Mabopane
Generator won’t start: Generator not starting
Flat batteries, failed chargers, stale fuel and starter faults, fixed on site.
Fuel and injector faults: Fuel system repairs
Contaminated diesel, blocked filters, air in the lines, lift pumps and injectors.
AVR and voltage faults: Voltage problems
Low, high or swinging voltage from the AVR, exciter or rotating diodes.
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.
Overheating
Shutdowns from blocked radiators, failed fans, thermostats and coolant leaks.
The Industrial Park
Factory units in the Ga-Rankuwa Industrial Park
The Ga-Rankuwa Industrial Park lies inside Tshwane but is owned by the North West Development Corporation, and its factory units have been refurbished since 2019 under the national industrial parks revitalisation programme. A tenant’s set may be newer than the building, or older and carried over.
So a repair starts with the basics: who owns the set, how the changeover is wired, and whether the load still matches the kVA. We measure each phase under load before blaming the AVR.
- Phase loads measured with the machines running
- Changeover wiring checked after any refurbishment
- The landlord or tenant told who owns what we find
Response
On site in Ga-Rankuwa and Mabopane in 1–2 hours
Technicians on site in 1–2 hours, 24/7. The area sits on the north-western edge of the metro, with Rosslyn between it and Akasia and the R566 leading to Brits across the North West border. Tell us the town and street, a landmark such as a school or church, and whether the set is portable or fixed.
While you wait, switch the appliances off and pull the extension leads, let a hot engine cool and check only the oil, fuel and breaker. Keep the set outside: its exhaust carries carbon monoxide. WhatsApp a photo of the label; emergency generator repair covers night calls.
Every make
Makes we repair in Ga-Rankuwa, Mabopane and Winterveld
We Service & Repair All Generator Brands. At homes and shops that means petrol portables, inverters and open-frame diesels from Kipor, Mac Afric and Bundu Power. Factory and school sets usually run Perkins, Cummins or Deutz engines with Deep Sea Electronics or SmartGen controllers. See our brand pages.
Prevention
Why the same generator fails twice here
A set that comes back with the same fault usually kept its cause: petrol bought for last month’s outages, a factory line added without resizing the set, or a battery left on a dead charger at a school. We fix the fault and name the cause in the report.
Servicing is how the cause goes. The Ga-Rankuwa and Mabopane generator service and maintenance page covers what a service includes and when it is due. Generator repairs explains how we trace faults; we also attend breakdowns in Soshanguve, the Rosslyn factories and Akasia, across Tshwane’s northern areas and the Pretoria hub.

FAQ
Frequently asked questions
Do you repair portable generators at homes in Winterveld?
Yes, in Winterveld, Mabopane and Ga-Rankuwa alike: petrol, inverter and small diesel portables, fixed where they stand. Free callouts and quotations, and you get a quotation before work starts.
Our factory unit in the Industrial Park was refurbished. Why does the generator now trip?
Often the load changed: new machines, rewired boards or one phase now carrying most of it. We measure each phase and the starting loads; see single- and three-phase power.
Can I plug the generator into a wall socket to run the whole house?
No. That makes the plug’s pins live and back-feeds the network, which can kill someone working on the lines. A changeover switch fitted by a technician is the safe way; see generator installation.
The school generator only cranks slowly after the holidays. What should we do?
Stop after two attempts so the battery keeps some charge. A slow crank after weeks idle points to the battery or its charger; tell us the make and kVA from the nameplate when you call.
