Generator Service Programs
Thompson Power Systems offers commercial generator service that extends your equipment’s life.
Maintenance and Monitoring Programs
Customer Value Agreements automate your service calendar. We track runtime hours and schedule oil changes, filter replacements, and inspections automatically. Remote asset monitoring keeps an eye on your system and streams performance data to our service center, so we can catch developing problems and contact you if we see a potential issue.
Testing and Compliance Services
Load bank testing validates your generator under full electrical load. We simulate real operating conditions to verify output capacity. Transfer switch testing meets NFPA safety codes, and we document switching speed and exercise cycles for your compliance records. Fuel management programs keep diesel clean through sampling, treatment, and tank cleaning services.
New Commercial Generators
Thompson Power Systems stocks Cat power systems for every application. New commercial generator options include diesel models for reliability, and we also offer natural gas units for clean operation. Our inventory ranges from compact backup systems to high-output industrial generators. You get current technology with efficient emissions controls.
Supporting equipment completes your power infrastructure:
- Battery storage systems provide instant backup capacity.
- Microgrids create independent power networks.
- Automatic transfer switches manage the transition between utility and generator power.
- Switchgear coordinates multiple units for greater capacity.
Our sales team helps you find systems that match your electrical load and budget.
Used Commercial Generators
Budget-conscious buyers benefit from our used commercial generator selection. Every preowned unit passes a full evaluation during which we inspect engines, test electrical output, verify cooling systems, and replace worn parts before certification. You receive dependable Cat equipment at substantially lower investment than new units require.
