Generator Makes & Models We Repair, Service & Maintain
Your generator’s data plate tells us its make, model, kVA and voltage, and the engine and alternator carry plates of their own. Send us photos of them and we arrive with the right filters, parts and diagnostic tools. If you only need to find your make, use our A–Z generator brands directory.
Callout fee waived when you accept our written quote. 1-year workmanship guarantee. See prices
- Diesel, petrol and gas
- Older and current sets
- A plate photo is enough to start

Identify your generator
How do I identify my generator?
Start with the data plate. On a standby set it is usually fixed to the alternator end or the canopy frame; on a portable it is usually on the frame beside the control panel. It lists the make, the model and serial number, the kVA and kW rating, the voltage, the phase and the frequency, which is 50 Hz in South Africa.
Read the kVA, not the size of the canopy. At the typical 0.8 power factor, a 20 kVA set supplies about 16 kW. Many plates also show separate standby and prime ratings, and we size any repair or load test to the right one.
Then look for the other plates. The engine has its own plate on the block, and the alternator has one on its housing. On a set badged FG Wilson you may find a Perkins engine and a Leroy-Somer alternator, and each plate decides different parts.
If a plate is missing or faded, photograph the whole set, the engine and the controller screen. We can usually identify the set from those, and we confirm the model on site.
Before the visit
What information should I send?
Send what you have; a missing model number never stops a booking.
Make
The brand on the canopy, and on the engine if it differs.
Model
From the plate or the manual, if you have it.
kVA
The rating printed on the data plate.
Fuel type
Diesel, petrol, gas or dual-fuel.
Controller
The panel name, or a photo of the display and any alarm.
Fault
What it does: no start, no power, a shutdown or a noise.
Data-plate photo
The quickest way for us to identify the set.
Generator photo
The canopy, the engine side and the installation, so we can plan access.
Why it matters
How the make and model change our visit
Identifying your set before we arrive saves you time and a second trip.
The right parts on the van
Filters, belts and fuel parts follow the engine model, so we bring the ones that fit.
The right controller tools
Deep Sea, SmartGen and other panels each show alarms their own way, and we read yours correctly.
The right tests
An inverter, an AVR set and a three-phase standby set each need different electrical tests.
A firm quote
With the model confirmed, we can price parts accurately and tell you about availability before work starts.
One generator, up to four makes
Most standby generators are assembled from parts by different manufacturers. The badge on the canopy is often the set builder, while the engine, the alternator and the controller each carry their own make and plate. We record all of them, because each one decides different parts and tests.
| Part | What it decides | Common makes |
|---|---|---|
| Engine | Filters, oil, fuel parts and the service schedule.Perkins, Cummins, Deutz, or a Honda GX engine on a petrol set | Perkins, Cummins, Deutz, or a Honda GX engine on a petrol set |
| Alternator | The AVR, windings and any rewind, which follow the alternator plate.Leroy-Somer, Stamford or Mecc Alte | Leroy-Somer, Stamford or Mecc Alte |
| Controller | How we read alarms, auto start and transfer faults.Deep Sea, SmartGen or PowerWizard; see generator controllers | Deep Sea, SmartGen or PowerWizard; see generator controllers |
| Set builder | The canopy, the wiring layout and the badge you see first.FG Wilson, Olympian, SDMO or Gentech | FG Wilson, Olympian, SDMO or Gentech |
Know your make already? Find it in the A–Z generator brands directory, which links every make we work on service and repair to its own repair guide. For a step-by-step walk through each line on the plate, read how to read a generator data plate. A Bundu Power badge names the set rather than the engine inside it; see repairs for Bundu Power generators.
Common Questions
Questions about identifying your generator
Where is the data plate on my generator?
On most standby sets the data plate is fixed to the alternator end or the canopy frame. On portables it is usually on the frame beside the control panel. The engine carries its own plate, and if you cannot find either, photograph the controller and the canopy badges instead.
What does the data plate tell you?
It shows the make, model and serial number, the kVA and kW rating, voltage, current, phase and frequency, and often separate standby and prime ratings. That is enough for us to plan parts and tests.
Why does my generator have more than one brand on it?
Most standby generators are built from an engine, an alternator and a controller made by different companies, then badged by the set builder. A set badged FG Wilson often has a Perkins engine, for example.
What is the difference between kVA and kW on the plate?
kVA is apparent power and kW is real power. Multiply kVA by the power factor, typically 0.8, to get kW: a 100 kVA set gives about 80 kW.
Can you service generators if the exact model is unknown?
Yes. A photo of the set, the fuel type and the fault are enough to start, and we confirm the model on site if the plate is unclear.
Do you repair older generator models?
Yes. We repair older sets that can still be diagnosed and for which parts or a repair path exist, whatever their age.
Do you service the brands you list?
Yes. ProService Generator Repairs services and repairs every generator brand listed in our Generator Brands directory, across Gauteng.
Where do I find the full list of brands you repair?
Our Generator Brands directory lists every make from A to Z, with links to the diesel, petrol and gas repair guides for each one.
