After-sales support
Generator servicing, fault finding and spare parts.
We help generator owners with planned maintenance, breakdown support, diagnosis and parts identification so the equipment is ready when it is needed.
Service options
Choose the level of support your equipment needs
One-time breakdown
Inspection, fault finding and a defined repair recommendation for an unexpected generator problem.
Planned maintenance
Scheduled engine, cooling, fuel, battery, alternator and control checks based on hours, time and operating conditions.
Service agreement
A tailored inspection and maintenance plan with agreed visit frequency, response terms and reporting.
Load testing
Controlled generator loading to observe output, temperatures, pressures, controls and operating stability.
Controls diagnosis
Alarm review, controller checks, start and stop logic, sensors, charging and interface troubleshooting.
Site commissioning
Pre-start inspection, start-up, operational checks and coordination with the installed system.
Spare parts
Start with the serial numbers
The spare-parts division supports generator engines, alternators, controls and associated equipment, including established brands such as Perkins, Volvo Penta and Cummins. Correct identification begins with the engine, alternator and generator serial plates.
For critical sites, Patsons can help develop a recommended spares list around the installed fleet, operating hours and lead-time risk rather than relying on an unverified generic kit.
- Routine service filters and consumables
- Engine sensors, belts, hoses and selected components
- Alternator service and electrical parts
- Generator controllers, relays and interface items
- Starting and battery-charging components
- Project-specific recommended spares packages

Frequently asked questions
Common questions
Can’t find what you need? Send us your requirement and our team will help.
Does Patsons assess generator breakdown requests?
Patsons assesses breakdown requests under agreed service terms. Mobilization is confirmed for the equipment, location, access, site conditions and technician availability.
Can Patsons maintain generators supplied by other companies?
The service team can assess many common generator, engine, alternator and control platforms. Share the serial details and fault or service requirement so compatibility can be confirmed.
How are generator parts identified?
Patsons reviews the engine, alternator, generator and controller serial details before identifying part requirements. Any proposed item is confirmed against the equipment data for that request.
How often should a standby generator be serviced?
The interval depends on the manufacturer schedule, running hours, fuel condition, environment and test regime. Standby equipment also needs periodic exercise and inspection even when operating hours are low.
