Local generators
Generators we work on in Montana and Sinoville
Family homes: Residential generator services
Silent diesels on a slab beside the house, and petrol portables wheeled out of the garage when the lights go.
Townhouse complexes: Standby generators
One shared set behind the security gate for the boom, the lights and sometimes the units, booked through the body corporate.
Shopping centres: Commercial generator services
The Kolonnade in Montana Park and the smaller centres in Montana and Sinoville, where standby carries tills, lighting and cold rooms.
Dr Swanepoel Road warehouses: Industrial generator services
Light-industrial units in Sinoville whose three-phase sets must start compressors, roller doors and machines, reached through a yard gate.
Medical standby: ATS and changeover problems
Montana Park has a private hospital on Dr Swanepoel Road; wherever a load is critical, changeover timing and steady voltage come first.
Schools, churches and plots: Diesel generators
Sets idle between term days or Sundays, and plot generators on the northern edge, often far from the gate.
Repairs
Generator faults we fix in Montana and Sinoville
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.
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.
Overheating
Shutdowns from blocked radiators, failed fans, thermostats and coolant leaks.
One road, two loads
Dr Swanepoel Road: hospital standby and warehouse motors
Dr Swanepoel Road passes two very different kinds of site. In Montana Park it runs past Netcare Montana Hospital, where standby protects critical loads; in Sinoville it is lined with warehouse and light-industrial units, where a three-phase set must drive motors, compressors and roller doors.
The faults follow the load. A critical-standby set is judged on how quickly the changeover moves the supply and how steady the voltage holds; a warehouse set on whether it can start a large motor without stalling or tripping. We test every set under its real load.
- Changeover timing measured from mains failure to load
- Load spread across the three phases checked
- The set left in automatic, with a written report
Response
On site in Montana and Sinoville in 1–2 hours
Technicians on site in 1–2 hours, 24/7. Sefako Makgatho Drive (the R513, formerly Zambezi Drive) is the area’s main road and leads to the N1, and Dr Swanepoel Road runs through both Montana Park and Sinoville. Tell us the complex or unit number, who opens the gate and where the set stands.
While you wait, check the fuel, the main breaker and the emergency stop, and note the controller message; stop cranking after two failed starts. Keep a portable outdoors and never plug it into a wall socket. Electrical, fuel and changeover work is for the technician; emergency generator repair explains a night call.
Every make
Generator makes we fix in Montana and Sinoville
We Service & Repair All Generator Brands. At homes here that usually means silent diesels from Bundu Power, Kipor or Mac Afric and petrol portables on Honda engines. Complex, shop and warehouse sets tend to be larger diesels on Perkins, Cummins or Deutz engines, with Stamford or Mecc Alte alternators and Deep Sea Electronics, ComAp or SmartGen controllers.
Prevention
Why a repaired set here can fail again
Most repeat callouts trace back to something the first repair left alone: a complex set gets a new battery but keeps the tired charger, a warehouse set a new filter while water sits in its tank, a home changeover a reset but not its burnt contact. Our report lists what else we saw.
Servicing is what stops the second call. The Montana and Sinoville generator service and maintenance page covers visits to homes, complexes, shops and warehouses. Our generator repair service explains how faults are found; we also repair sets in Annlin and Wonderboom, Kameeldrift and Pretoria Moot, and across the Pretoria hub.

FAQ
Frequently asked questions
Our townhouse complex in Montana shares one generator. Who arranges the repair?
Usually the body corporate or managing agent. We agree access at the gate, repair the set and its changeover, and send the report to whoever booked, so the trustees keep a record of the work.
Can you repair the three-phase generator at our Sinoville warehouse?
Yes. We repair three-phase diesel sets and their changeovers, check the load balance across the phases, and test the set while your compressors or machines start, so a stall or trip shows before we leave.
The generator runs but our Montana Park house stays dark. What is wrong?
Usually the changeover: a failed contactor, a mains-sensing fault or a tripped breaker on the generator side. Leave the panel closed; we trace it on site. Running but no power explains more.
Do you come out at night or over a weekend in Sinoville?
Yes. We work 24/7. Send the make, the kVA and a photo of the controller screen on WhatsApp, and the likely parts come with the technician on the first visit.
