Generating sets and power equipment
Generating sets from China, specified for your site
Sinospect supplies diesel generating sets, transfer switching and power equipment to EPC contractors, integrators and industrial buyers. Sets are specified against the site's duty, load-bank tested in the factory against agreed acceptance criteria, and documented for the country they are going to.
Send a load schedule, single-line diagram or specification to start. These controls can also be applied separately when the buyer purchases direct.
Project context
A genset is bought on the datasheet and judged on the site
Generating sets for project sites worldwide are routinely sourced from qualified Chinese manufacturers. The attraction is a mix of manufacturing depth, rating availability and delivery capacity. The risk is that a set is ordered against a catalogue rating and arrives against a real duty, on a site with an ambient temperature, altitude, fuel quality or noise limit the order never mentioned.
The failures that follow are rarely mechanical. They are a missed commissioning date, an enclosure that breaches a site limit, a document pack that will not clear customs, or a warranty nobody can execute across a border. Sinospect controls that work: specification and duty review, manufacturer screening, witnessed load-bank testing, document coordination and shipment follow-up.
Sinospect scope
Between the load schedule and factory-side execution
Sinospect does not replace the EPC, owner's engineer or local design office. The role is to control the manufacturer-side work that creates delay, technical drift and documentation gaps.
- 01
Input
Load schedule or specification
Load profile, prime or standby duty, site conditions and derating, single-line diagram and destination standards become the controlled buying basis.
- 02
Award gate
Supplier qualified
Factories are screened against the required engine, alternator, controller and integration capability; offers and exclusions are compared in writing.
- 03
Factory gate
FAT and load test
Load-bank and functional acceptance are witnessed against the agreed duty, with deviations corrected or carried as explicit release conditions.
- 04
File gate
Documents closed
Test records, compliance evidence, marking, manuals and customs documents are checked before the set is packed and dispatched.
- 05
Delivery gate
Delivery controlled
Packing and shipment are followed through to the agreed point, with commissioning interfaces, spares and warranty responsibilities already in writing.
Start with the electrical file you already have.
A load schedule, specification or single-line diagram is enough for an initial route. We will identify what must be clarified before supplier comparison and what evidence should control factory release.
- Minimum input
- Load schedule, specification or single-line diagram
- First response
- Duty gaps, supplier route and proposed FAT/load-test basis
- No call required
- The initial review can be completed in writing
Equipment families
Generating sets, and what has to work with them
Ratings from small standby sets to multi-megawatt prime power, plus the switching, conditioning and distribution equipment required for a complete installation. Assemblers buying engines rather than complete sets are covered on the engine power packs page.
Diesel generating sets
Prime and standby sets for construction power, plant commissioning, industrial backup and standalone installations — specified against the duty the site actually runs rather than a catalogue rating.
- Engine, alternator and controller combination qualified against declared duty and site derating
- Open-skid, canopied and containerised configurations, with sound attenuation set as a specification
- Witnessed load-bank testing against the agreed acceptance and release criteria
Transfer switching and LV distribution
Automatic transfer switches, changeover panels and low-voltage boards, reviewed for the interface with the set's controller and with distribution equipment already on site.
- ATS rating, transition type and control interface confirmed against the set
- Board schedules and protection coordination reviewed before manufacture
- Functional tests witnessed with the set rather than in isolation
Voltage stabilisers and power conditioning
Three-phase stabilisers and conditioning equipment for sites where the incoming supply, not the load, is the problem — common on grids with wide voltage excursions.
- Correction range and response specified against measured site conditions
- Compatibility with generating-set operation and transfer sequencing
- Routine tests documented before shipment
Transformers and MV switchgear
Distribution transformers, MV switchgear and cable for interconnection and delivery points, qualified against applicable standards with documented factory tests.
- Qualification against project specification and applicable standards
- Documented routine and type tests, witnessed in the factory when needed
- Coordination with local engineering on interfaces and dimensions
Solar, inverters and battery storage
Photovoltaic modules, string and central inverters and LFP storage for hybrid and self-consumption projects, where a generating set is one half of the installation.
- Manufacturer qualification against specification and applicable certifications
- Grid compatibility, safety documents and operating limits reviewed
- Factory inspection and pre-shipment test coordination
Before you order
The six questions buyers actually ask
These six questions recur in international power-equipment orders: delivery, configuration, destination standards, customs documentation, warranty and documentation language. Each needs a written answer before the deposit rather than after delivery.
Will it arrive in time for commissioning?
Production and shipping dates are fixed against your commissioning date before the order is placed, then reported against that date while the set is built — rather than confirmed once at order and revisited at the port.
Canopy, containerised or open skid?
Enclosure type, sound attenuation target and transfer-switch integration go into the specification and are confirmed with the manufacturer before production. Retrofitting an enclosure after build is the expensive way to discover the site had a noise limit.
Which standards apply where it is going?
The standards the destination market enforces are named in the technical specification before manufacturer selection, so compliance is a purchase condition instead of a customs discovery.
What documentation clears customs?
Certificates, test reports, marking evidence and customs paperwork are compiled as part of the order and checked against the destination's import requirements before the container leaves.
Who covers warranty and spare parts once it is on site?
Warranty holder, spare-parts route and response path are settled in the order documents before the deposit. Cross-border projects need this named rather than assumed from a factory's standard terms.
Can the documentation be in French?
Documentation language is an order requirement like any other — French where the site and the operator need it, instead of whatever the factory ships by default.
Documentation discipline
Documents that clear customs and satisfy the owner
A set that is built, tested and shipped can still stop at a border. The document pack is assembled against the destination's import requirements before manufacturing, not compiled from whatever the factory happens to issue at dispatch.
Technical file and test records
Datasheets, load-bank and routine test reports and witnessed acceptance records, checked against the specification the order was placed on.
Compliance and marking evidence
Applicable certificates, declarations and marking evidence assembled against the destination market's requirements, not a factory's default export set.
Customs and shipping pack
Invoice, packing list, origin and transport documents prepared so the consignment clears rather than sits.
Warranty and after-sales responsibilities
Warranty terms, spare-parts conditions and after-sales responsibilities are settled separately and in writing, because they govern what happens on site months after the document pack has been accepted.
Client profile
Who buys power equipment this way
Contractors, integrators and industrial buyers who need manufacturer-side control in China rather than a catalogue and a shipping date.
EPC and industrial contractors
Contractors needing temporary site power, commissioning power or plant backup on international projects, where a slipped delivery stalls a milestone rather than an invoice.
Integrators and resellers
Electrical equipment distributors and panel builders who integrate sets into their own scope and need a consistent supply basis, technical documentation and terms they can quote against.
Direct buyers and manufacturers
Industrial operators buying for their own installations, and equipment manufacturers integrating sets into distribution equipment they supply onward.
Operating position
Sinospect's role in a power equipment order
- Operating offices in Hong Kong and Ningbo for manufacturer follow-up and document coordination.
- Factory-side work covering manufacturer screening, inspections, witnessed testing and production reporting.
- International delivery coordination, with Morocco-based project support available when the agreed scope requires it.
- Documentation issued in the language the site operates in, and structured for customs and owner examination.
- Supply against the buyer's specification, not a single factory catalogue. Where Sinospect is the contracting supplier, any payment-linked factory release follows the acceptance criteria agreed in the order; buyer-direct engagements leave commercial release with the buyer.
- China-based supplier control built over 20+ years and applied to power equipment procurement.
The same execution discipline runs across other Sinospect sectors, including healthcare procurement, where documentation and supplier qualification are equally load-bearing.
