SELL YOUR GENERATORS & TRANSFER SWITCHES
Sell surplus diesel and natural-gas generators, automatic transfer switches, switchboards and generator controls nationwide. Free evaluation and pickup.
We purchase standby generators, prime-power generator sets, automatic transfer switches, paralleling switchgear, generator controls, and related emergency-power equipment. Our nationwide buyers work with hospitals, data centers, commercial buildings, industrial plants, utilities, contractors, and property owners replacing or decommissioning backup-power systems.
Generator value depends on more than nameplate kilowatts. Engine manufacturer, generator end, fuel type, voltage, hours, model year, service records, enclosure, emissions configuration, and load-test history all matter. Transfer switches are evaluated by manufacturer, amperage, poles, voltage, transition type, withstand rating, enclosure, controller, and compatibility with current or installed systems.
We can evaluate a single ATS, a packaged generator set, or an entire emergency-power plant that includes fuel equipment, controls, breakers, switchboards, and paralleling gear. Removal planning is based on safe access, isolation status, rigging requirements, crane needs, and transportation dimensions. Share photos and specifications before dismantling so related components remain identifiable.
Types of Generators & Transfer Switches We Buy
We evaluate the following equipment categories and related surplus. Items outside this list may also qualify when manufacturer, model, ratings, quantity, and condition are identifiable.
- Diesel Generator Sets — Standby and prime-power units from commercial buildings, industrial plants, hospitals, and data centers.
- Natural-Gas and Bi-Fuel Generators — Packaged gaseous-fuel systems, controls, enclosures, radiators, and associated switchgear.
- Automatic Transfer Switches — Open-transition, delayed-transition, closed-transition, bypass-isolation, and service-entrance-rated ATS equipment.
- Paralleling Switchgear — Generator synchronization, load-sharing, master control, distribution, and breaker sections.
- Generator Control Panels — OEM controllers, annunciators, protective relays, battery chargers, and remote monitoring equipment.
- Complete Emergency-Power Packages — Generator, ATS, distribution, fuel, cooling, exhaust, and control equipment evaluated as one project.
Manufacturers We Evaluate
Common manufacturers include Caterpillar, Cummins, Kohler, Generac, MTU / Rolls-Royce, Detroit Diesel, Onan, ASCO, Russelectric, Eaton, Siemens, Schneider Electric. Manufacturer names identify equipment we evaluate; no affiliation or endorsement is implied.
Where Generators & Transfer Switches Becomes Surplus
Data center upgrades
Capacity changes and campus redevelopment can release generator sets, ATS units, paralleling gear, and electrical distribution together.
Healthcare modernization
Hospitals replace emergency-power equipment during code, capacity, and reliability projects.
Commercial redevelopment
Office, retail, hotel, and institutional renovations often retire functional standby systems before end of life.
Industrial closures
Plants and warehouses may have packaged generation, transfer equipment, fuel systems, and switchgear available in one liquidation.
What Affects Market Value
Capacity and configuration
Kilowatt rating, voltage, phase, frequency, power factor, and standby versus prime rating determine the buyer pool.
Engine hours and maintenance
Documented service, exercising, load-bank testing, fluid analysis, and operating hours support condition assessment.
Emissions and age
Engine tier, model year, permitted use, and geographic restrictions can affect where equipment can be reused.
ATS specifications
Amperage, poles, transition type, withstand rating, enclosure, bypass isolation, and controller family are central to ATS value.
Removal conditions
Indoor access, rooftop placement, weather enclosure, crane reach, fuel isolation, and transportation dimensions affect logistics.
How to Prepare a Quote Request
Clear specifications and condition details reduce uncertainty and help our purchasing team provide a more useful review. You do not need a formal spreadsheet, but identification matters.
- Photograph generator and ATS nameplates, engine data plate, controller display, breaker, enclosure, and overall installation.
- Record kilowatts, voltage, phase, frequency, fuel type, engine hours, year, and operating condition.
- Collect maintenance records, load-bank results, service reports, and information about batteries, coolant, and fluids.
- Describe removal access, floor level, door openings, rooftop or basement location, crane access, and whether equipment is disconnected.
How the Selling Process Works
- Send specifications and photos. Call (951) 403-5738, text us, or use the online quote form with nameplates, quantities, condition, and location.
- Receive an equipment review. We check compatibility, reuse demand, lot quality, and practical logistics.
- Review the written offer. Equipment included, pickup assumptions, and payment terms are confirmed before scheduling.
- Coordinate pickup. For accepted qualifying lots, we arrange appropriate transportation around your facility schedule.
Frequently Asked Questions
- Do you buy generators that are still installed?
- Yes. We can evaluate installed equipment and coordinate removal after it is safely isolated. Access, rigging, fluids, permitting, and transportation are reviewed before scheduling.
- Do you buy automatic transfer switches without a generator?
- Yes. We purchase individual ATS units, bypass-isolation switches, service-entrance transfer equipment, controllers, and complete transfer-switch lineups.
- What generator information is needed for a quote?
- Provide generator and engine model numbers, kilowatts, voltage, fuel, hours, year, condition, maintenance history, location, access, and clear nameplate photos.
- Can you buy a complete emergency-power system?
- Yes. We can evaluate generators, ATS units, paralleling gear, switchboards, breakers, controls, and related equipment as one coordinated package.
