Generators we work on in Hermanstad and Danville
Factories and engineering works: Industrial generator services
Three-phase sets in Hermanstad’s industrial area, reached through a yard gate and carrying machines, compressors and lighting.
Logistics and distribution warehouses: Commercial generator services
Sets behind dock doors, scanners and the dispatch office, idle for weeks and then asked to run a whole shift.
Motor and automotive businesses: Voltage problems
Workshops with vehicle lifts, compressors and diagnostic equipment, where a starting motor drags the voltage down.
Small workshops: Single vs three phase
One diesel set carrying a welder, a grinder and the office, often loaded unevenly across its three phases.
Homes in Danville and Elandspoort: Residential generator services
Silent diesels in side passages and on slabs at free-standing homes, plus petrol portables for smaller loads.
Schools: Generator not starting
Sets that carry offices, lights and alarms through term and stand unused over the holidays, then fail to crank.
Repairs
Generator faults we fix in Hermanstad and Danville
AVR and voltage faults: Voltage problems
Low, high or swinging voltage from the AVR, exciter or rotating diodes.
Battery and charging faults: Battery not charging
Chargers, charge alternators and batteries that cannot crank the set when the mains fails.
ATS and changeover problems
The set runs but the building stays dark, or the load never returns to the mains.
Fuel and injector faults: Fuel system repairs
Contaminated diesel, blocked filters, air in the lines, lift pumps and injectors.
Generator won’t start: Generator not starting
Flat batteries, failed chargers, stale fuel and starter faults, fixed on site.
Overheating
Shutdowns from blocked radiators, failed fans, thermostats and coolant leaks.
Local conditions
Older industrial yards beside the power station
The City of Tshwane’s Pretoria West power station, a coal-fired plant built in 1952, was producing no electricity when the council approved plans to lease it out in 2024. Around it, the factories, warehouses and motor businesses of Hermanstad and Pretoria West keep their own generators for outages.
Where premises have changed hands, we meet sets sized for a previous tenant, changeover panels older than the lease and cables across the yard. We measure what the set carries now, phase by phase, before replacing parts.
- Load measured on each phase under real machines
- AVR and governor checked as motors start
- Old changeover panels tested, isolated first
Response
On site in Hermanstad and Danville in 1–2 hours
Technicians on site in 1–2 hours, 24/7. The area lies west of the CBD, linked to it by WF Nkomo Street (formerly Church Street West). Tell us which yard gate to use, who signs contractors in, or, at a house, whether the set sits in a locked side passage.
While you wait, keep to safe checks: fuel, main breaker, emergency stop and controller screen, and stop after two start attempts. Never feed the house by plugging a portable into a wall socket. WhatsApp the nameplate and controller; emergency generator repair covers a night call.
Every make
Generator makes we repair west of the city centre
We Service & Repair All Generator Brands. Hermanstad’s factories and warehouses mostly run three-phase diesels on Perkins, Cummins, Deutz or John Deere engines, with Stamford or Mecc Alte alternators and Deep Sea Electronics or SmartGen controllers. Danville homes and workshops run silent diesels from Kipor, Bundu Power and Mac Afric, and Honda or Ryobi portables. See our brand pages.
Prevention
Why a Hermanstad generator breaks down again
A repeat breakdown means the cause stayed: a new AVR on a set still overloaded on one phase, a fresh battery on a drifting charger, or clean filters fed from a tank with water in it. Our report lists what else we found.
Servicing breaks the cycle. The Hermanstad and Danville generator service and maintenance page covers works, warehouse, school and home plans. Generator repairs explains how we find a fault; we also work in the Pretoria CBD, Atteridgeville and Laudium and Erasmia, across the Pretoria West sub-region and the Pretoria hub.

FAQ
Frequently asked questions
Our Hermanstad works set dips every time the compressor starts. Is it faulty?
Not always. A compressor motor draws a heavy starting current that a slow AVR or a set sized for an earlier tenant cannot hold. We measure the dip on each phase; see voltage problems.
Can you repair the generator at our distribution warehouse without stopping dispatch?
Mostly, yes. Diagnosis and most repairs happen with the warehouse on mains and the set isolated; the loaded test and changeover check are booked for a quiet hour. We work 24/7.
Do you repair home generators in Danville, Elandspoort and Proclamation Hill?
Yes: silent diesel standby sets, changeover switches, chargers and controllers, and petrol portables. A portable must feed appliances through its own sockets or a proper changeover, never a wall plug.
The school generator stood over the holidays and now will not start. What failed?
Usually the battery or charger, sometimes stale fuel or a controller left out of automatic. Leave the start button after two tries; we test battery, charger and fuel first. See generator not starting.
