Commercial generator fault diagnosis
A commercial failure is usually a standby set that did not take the building, took it and then tripped, or has been unreliable between outages. The visit starts with that result: no automatic start, no transfer, a controller alarm, low voltage, or a shutdown under the shop or office load.
Most of these sets are diesel, with an ATS and a controller, in a plant room, a yard or a basement. Access, a site contact, and whether the mains is currently off all change how the visit is planned. Petrol sets at a small shop are still booked, on the petrol pages, when that is the fuel.
Servicing and maintenance are separate from the breakdown. A planned service changes what is due. Maintenance is the readiness between those visits: batteries, start tests and faults caught before the next outage. Load testing is used when the site needs to know the set can carry a defined load.
The commercial visit
Diesel standby, automatic start and looking after the set
Commercial diesel generator repairs
Fuel, starting, cooling and output on the diesel sets that carry offices and retail. The diesel hub lists engine brands.
Standby generator repairs
Sets that wait. A fault after weeks of sitting is often the battery, fuel or a controller that was already in alarm.
ATS and automatic start problems
The building stayed on a dead mains supply. The start signal and the transfer are the commercial version of that complaint.
Generator controller repairs
Alarms that stop a start overnight, when nobody is at the panel to press a button.
Commercial generator servicing
Oil, filters and the checks due for that engine, booked so the visit is not only after a failure.
Preventative maintenance
Hours, batteries and a start test on a contract or a planned visit. It is wider than one oil change.
Load testing
A controlled load when a start in the plant room does not prove the tenants or the tills.
Generator sizes
Commercial sets often sit from the smaller business range upward. The plate, not the canopy, is the size.
Commercial generator callouts
The suburb, a site contact, the fuel and the fault. Same-day is offered only when a slot is open.

Common Questions
Questions about commercial generator repairs
What is a commercial generator repair?
A repair on a generator serving a business premises, such as an office, shop, complex, warehouse or workshop.
Do you work on body corporate and complex generators?
Yes. Access and a person who can be on site are arranged with the booking.
Is commercial the same as industrial?
No. Commercial here means business premises and standby for that building. Industrial is the larger diesel plant and heavy standby work.
The generator did not start during load shedding. Can you look at that?
Yes. Automatic start, the battery and the ATS are the first split on a standby set that stayed silent.
Do you service commercial generators as well as repair them?
Yes. A planned service is booked separately from a breakdown so the scope is clear.
Can you test whether it will carry the building?
A run proves it starts. A load bank test is the booking when you need a defined load.
