Lovol diesel
We repair and service Lovol diesel generators on standby and commercial sites across Gauteng. We treat each Lovol as a complete genset, checking the engine, the canopy and the controller together, and we quote before any work.
Independent service and repair: Lovol is a trademark of its owner, and ProService Generator Repairs is not a Lovol dealer or agent.
Callout fee waived when you accept our written quote. 1-year workmanship guarantee. See prices

Lovol sets usually arrive as complete canopy gensets, so a fault in airflow, the controller or the engine can look much the same from outside. We record the canopy label and the engine plate, then test each part in turn.
Many Lovol sets are fully enclosed, which makes access and cooling part of every diagnosis.
We change Lovol engine oil and filters to the data plate schedule, and test the battery and charger on standby sets between outages.
Every service includes a controller alarm review and a check of canopy access and airflow.
We work on Lovol standby and commercial sets where access allows. The set plates give us the kVA and controller.
When a Lovol will not crank, we check the battery, the starter and any inhibit on the installed controller.
When it cranks without firing, we trace the fuel filter, air in the lines and the solenoid.
We confirm the filter housing and lift pump on the Lovol engine before ordering parts.
Smoke under load usually links to fuel delivery or canopy airflow, so we check louvre clearance on enclosed Lovol canopies too.
Lovol installations use different controllers depending on the supplier. We read the alarm text from the panel on your set.
When the set runs but the building does not transfer, we test the ATS and the panel’s start output.
For overheating, we check coolant, the radiator and enclosure ventilation.
We measure voltage at the breaker and AVR once engine speed is stable.
We check your Lovol as one genset and follow each fault path separately.
Book a repair when the set fails to start, trips on load or loses output.
Book a service when fluids are due and the set still runs on test.
A Lovol canopy can idle evenly and hunt under building load. We compare fuel delivery and alternator capacity with the load applied.
A fuel or battery repair on a moderate-hour Lovol is usually worthwhile. Major engine work on a high-hour set needs a comparison with replacement.
When the engine, alternator and controller all need major work, we price a complete replacement set alongside the repair.
Your cost depends on whether the fault is in the engine, the canopy controller or the alternator. A belt replacement typically costs R450 to R1,400; a cooling system repair R1,800 to R5,000.
The Lovol faults we see most often, and our first checks.
The battery, the starter or a panel inhibit.
The fuel filter, air in the line or the solenoid.
Coolant, the radiator or restricted airflow.
The ATS or the panel’s start output.
The AVR or alternator, once engine speed is stable.
We cover the Lovol engine, canopy and controller together.
Lovol sets on commercial sites are familiar ground for us.
We check louvres and radiators on enclosed sets as standard.
