Yes, we repair generators in Rant-en-Dal, wherever the set stands on the property. We are open 24/7 and arrive within 1 hour for breakdowns; the fault is diagnosed on site and quoted in writing before any work.
Rant-en-Dal means “ridge and valley” in Afrikaans. On a sloping stand the generator often ends up at the bottom of the garden or beside a garage, well away from the distribution board.
Distance matters. A long cable loses voltage, most of all when heavy loads such as a pool pump or geyser start, so the set can read fine at its own panel while the house sees low voltage. We measure at both ends and tell you whether the fix is the cable, the load or the set.
Placement matters too. A canopy tucked into a corner or against a wall can draw in its own hot air and overheat on a long run. We check airflow, the radiator and the coolant on every visit.
Breakdowns attended 24/7. We diagnose first, then quote the repair in writing.

What happens next
Charlie, lead technician: Degree in Mechanical Engineering, Degree in Electrical Engineering, Diesel Plant Fitter. Generator specialists since 2000.
On larger Rant-en-Dal properties, distance and placement cause faults that a quick test at the canopy will miss.
The set reads normal but the house dims. We measure at both ends of the cable.
Hot air recirculates around the canopy. We check airflow, the radiator and the coolant.
Pool pumps and geysers start hard. We measure the surge against the set’s capacity.
We test the ATS timing and contacts with the house connected.
We test the mains sensing and the controller’s start signal.
When we install, move or service a set on a sloping stand, we check that the cable between the generator and the board suits the distance and the load, that the canopy has room to breathe, and that it stands on a firm, level base. If any of these needs work, you get a written quote first.
Note whether the set tries to start on its own when the power fails, and whether it starts on the button. Call or WhatsApp 082 057 4605 with both answers.
Rant-en-Dal’s name describes the ground: ridges and dips that leave many stands sloping, with Noordheuwel, Kenmare and Monument close by. On a callout here we allow time to follow the cable from the set to the board, because the fault is not always at the generator. A set at the low end of a garden can also stand in run-off after a Highveld thunderstorm, so we check the plinth, the battery terminals and any wiring or connectors that sit close to the ground before we sign the repair off.
We service the automatic diesel and gas standby sets that suit larger Rant-en-Dal homes, as well as portable petrol sets.

On a Rant-en-Dal property the set often stands far from the house, and a long or undersized cable loses voltage under load. We measure at both ends and quote for the cable, the load or the set, whichever is the cause.
Yes. A canopy without enough clear space around it can draw in its own hot exhaust air. We check the airflow, clean the radiator, test the coolant and fan, and tell you if the set needs more room.
Yes. We quote for relocating the set, the cable and the base, keeping it outdoors and away from windows for carbon monoxide safety.
Yes. On every service and repair we let the set start, take the house load and hand back to mains, and we check the timing.
