Diesel generator set
10 kW-2 MW gensets, open or silent-canopied, prime or standby rating. We verify the alternator, governor, and the actual load-test report, not just the brochure.
InquireGenerators & UPS
The Generators & UPS we reverse-engineer, verify, and negotiate on your behalf. Pick a model or send us the spec.
UPS system
Online double-conversion UPS from 10 kVA to 1 MVA with battery management. Efficiency curve, transfer time, and battery-bank spec are confirmed against factory test data.
InquireStatic transfer switch
Automatic source changeover for critical loads, 100-4000 A, closed or open transition. Break-before-make timing and switching electronics are verified in the factory.
InquireThe key fields for generator-set equivalence
A diesel generating set is an assembly of four components — baseframe, engine, alternator, controller — and the same brand badge can carry entirely different engine families depending on the build lot. Equivalence therefore has to drop to component level first: engine make and model, alternator make and excitation system, controller family, and the evidence chain of the complete-unit tests.
The verification checklist: nameplate-versus-datasheet consistency; a load bank report with real partial and full-load steps — not the four characters "factory acceptable"; baseframe fuel-tank capacity matched to your site layout; and, where paralleling is required, the completeness of the control interface story.
One guide in this column (Perkins equivalent) already walks the detail. The free 48-hour initial screen remains free: send us the brand and application, get a first verdict, then decide how deep to go.
Generating sets: four assemblies from one industrial belt
A genset is an assembly of four parts — baseframe, engine, alternator, controller. All four can be sourced within the same belt, which is why lead time and the spares position look different here.
01
The wind side shows the scale of it
In 2025 Chinese turbine manufacturers installed 18,291 units, about 67% of the world total. Chinese wind-turbine assembly holds over 60% of global manufacturing, core components such as blades, gearboxes and main shafts account for over 70% of world output, and the global top five turbine OEMs were Chinese for the first time.
02
Alternators and controls share that chain
The alternators, excitation systems and controllers on this chain overlap heavily with industrial motors and drives, so spares and substitute parts are far more available than they would be on a fully imported solution.
03
But the unit-level evidence chain is yours to read
One brand badge can carry different engine families inside a single serial-number range. The configuration covered by the type test — radiator class, baseframe tank, control-panel version — has to be matched line by line against the quotation, and a load-bank report reading only "factory acceptable" is not a test result.
04
And if you intend to parallel
Controller protocol, governor interfaces and genuine load-sharing history should be shown as they operate rather than as a brochure claim. The free screen settles one supplier first and names the questions before engineering hours are spent.
Send the rating and the application
Prime or standby, the site conditions and whether paralleling is required are enough to start. One verdict on the supplier and one core reason within 48 hours; the paid tiers then read load-bank results, type-test scope and component-origin records at the works.

Equipment sourcing FAQ
How do you tell a real factory from a trading office?
We cross-check the business-licence scope, social-insurance headcount, and customs filing. A "manufacturer" with two insured staff and no production-equipment records is almost always a trader reselling someone else's unit. We also look at whether the address is an industrial park or a serviced office.
Can you match a specific brand or model to the right manufacturer?
Yes. Send us the brand and model, or just a nameplate photo, and we reverse-engineer the key parameters: rated voltage, impedance, cooling class, protection grade. Then we shortlist Chinese manufacturers whose product line genuinely covers those parameters. This is the Spec Match tier.
Can you negotiate on my behalf?
Yes. The Procurement Execution and Remote Audit tiers include independent negotiation support, and On-Site Verification covers the physical checks; either way, we sit on your side of the table, not the factory's.
Do you take commissions from factories?
Never. We're paid only by you, on a flat fee. When we name an alternative supplier, we state in writing that we have no financial relationship with it. No referral fees, no kickbacks, no revenue share. Our only incentive is that your deal closes.
