A large exhibition rewards preparation. Without a defined application and specification, buyers often collect quotations for products that look similar but differ in construction, certification scope, accessories, packaging or delivery terms.

Pre-fair checklist

• □   Define the product and application.
• □   Identify the target country or region.
• □   List the technical standards and required certification or listing basis.
• □   Estimate the trial quantity, initial order and annual demand.
• □   Set the required delivery window and destination port.
• □   Define labeling, reel, carton and private-label requirements.
• □   Prepare one RFQ and one supplier comparison sheet.
• □   Book meetings with priority suppliers and leave time for follow-up discussions.

Build the product list around the project

For PV projects, start with the required solar DC cable families, relevant solar PV connectors, cable assemblies and balance-of-system items. For storage projects, separate residential energy storage systems from commercial and industrial energy storage systems because their design inputs, integration work and purchasing evidence differ.

Do not rely on a product name alone. Two products with similar names may use different constructions, approved ranges, interfaces or documentation. A useful RFQ identifies the parameters that determine technical fit and quote comparability.

Solar cable specification checklist

For example, "Need H1Z2Z2-K cable" is incomplete. State the conductor size, project standard, system voltage, route and installation conditions, required evidence, quantity, packing and destination market. The final cable size still requires the project calculation and interface check.

Canton Fair is too large for unstructured booth visits. Build a preliminary list and identify what each meeting must confirm.

Research questions should be specific: Does the supplier manufacture the quoted product? Does the document holder match the manufacturing entity? Does the approved scope cover the quoted model, construction and size? Can samples and current technical documents be provided?

A brochure is only an introduction. A defensible evaluation separates company identity, manufacturing, technical evidence, commercial terms and export execution.

If manufacturing evidence is important to the decision, review SINELINK's capabilities and factory information before requesting product-specific documents or arranging an audit.

A logo on a catalogue or product image is not enough. For a product sold on the basis of certification or listing, verify the certificate or listing number, issuing body, holder, manufacturer, factory location, product family, construction, size range, standard and current status. The quoted product must fall within the approved scope.

Questions for document verification

• Is the document issued to the same entity that will manufacture the quoted product?
• Does it cover the exact model or product family?
• Are the conductor size, construction, marking and voltage context within scope?
• Can the record be checked through the certification body or listing database?
• Do the latest datasheet, sample marking and quotation describe the same product?

Treat a missing or mismatched field as an open verification item, not as automatic proof of non-compliance. Ask the supplier to reconcile the document, product marking and quotation before approval.

Use one completed specification for every supplier. This makes technical and commercial differences visible before price comparison.

• □   Cable designation and applicable project standard
• □   Conductor material, class and cross-sectional area
• □   Maximum system voltage and corrected circuit current
• □   Ambient conditions, grouping, routing and installation method
• □   Insulation, sheath, UV, flame and halogen requirements where applicable
• □   Current certificate or listing required by the project
• □   Cable color, marking, packing length and quantity
• □   Connector model, cable outer diameter and termination tooling
• □   Destination, Incoterm, requested delivery and batch-document requirements

Questions to ask a solar cable supplier

1. Which standard and current document apply to the quoted cable?
2. Who holds the certificate or listing and where is the cable manufactured?
3. Which construction, conductor sizes and markings are within scope?
4. What routine, type or batch tests are available for review?
5. What application and installation limits should the buyer check?
6. Which packing, printing and assembly options can be confirmed?
7. What are the MOQ, quotation basis and production lead time?
8. What information is still required before a firm quotation?

Use the Solar DC Cables category to compare cable families before moving to model-level verification.

Evaluate the connector together with the cable, termination method and system design. Similar housings do not prove identical interfaces or approved combinations.

• □   Exact connector manufacturer, family and model
• □   Rated voltage and current for the intended configuration
• □   Conductor size and cable outer-diameter range
• □   Mating interface and permitted counterpart
• □   Ingress protection and environmental limits for the assembled product
• □   Contact material, locking method and required assembly tools
• □   Applicable certification and test documentation
• □   Installation instructions, inspection criteria and packaging

Do not assume that every connector marketed as "compatible" can be cross-mated. Confirm the permitted mating combination, the product instructions and the project's certification requirements. Use the connector category for model selection.

Compare inline, branch and protection-focused PV connector options by circuit function and verified model data.

Energy storage procurement requires project-level inputs because power, usable energy, duty cycle, electrical architecture, environmental conditions and local requirements affect the system design. Do not compare only the nominal kWh figure.

Battery and system inputs

Ten questions for an energy storage supplier

1. What application and operating profile is this configuration designed for?
2. Which battery chemistry and cell model are proposed?
3. What are the nominal energy, usable energy and rated power?
4. How is cycle life stated and under which test conditions?
5. Which BMS, PCS or inverter interfaces and protocols are supported?
6. Which protection, cooling and fire-safety functions are included?
7. Which standards, certifications and transport documents apply?
8. What is included in the warranty and which operating conditions apply?
9. Who is responsible for design, installation, commissioning and after-sales support?
10. Which project data are needed before a firm configuration and quotation?

Start from the appropriate product family: residential energy storage systems for home-scale configurations, or commercial and industrial energy storage systems for business-site and larger project requirements.

A lower unit price may reflect a different construction, scope, approved range, packing method, delivery term or warranty. Normalize every quotation before ranking suppliers.

SUPPLIER COMPARISON WORKSHEET

A structured RFQ gives suppliers the same technical and commercial basis. It also reveals which inputs are missing before a firm quote is possible.

Solar cable RFQ fields

• Product: designation, standard, conductor, cross-sectional area, voltage, construction, color and marking.
• Application: system voltage, current, route, environment, installation method and connector interface.
• Evidence: certificate or listing requirements, datasheet, test report and batch documents.
• Quantity: trial order, initial order, annual forecast and packing length.
• Commercial: price break, MOQ, lead time, payment, Incoterm and quote validity.
• Logistics: destination, port, packaging, label and shipping-document requirements.

Energy storage RFQ fields

• Project location, application and operating objective.
• Required power, usable energy, duration and expected duty cycle.
• Site electrical data, grid requirements and connection constraints.
• Battery, BMS, PCS/inverter, protocol and monitoring requirements.
• Ambient conditions, installation location, enclosure and cooling constraints.
• Required standards, certificates, tests, transport and safety documentation.
• Delivery scope, commissioning, training, warranty and service expectations.

For a project-specific response, send the RFQ and available BOM to SINELINK or email sales@sinelinkenergy.com.

Use a repeatable interview structure. This prevents a strong sales presentation from replacing the evidence needed for comparison.

• □   Company name, booth, contact, email, phone and website
• □   Product, model, specification and application
• □   Certificate or listing reference and promised documents
• □   Sample availability and sample identification
• □   MOQ, price indication, quote basis and validity
• □   Lead time, packing, payment and Incoterm
• □   Open technical questions and owner
• □   Next action, due date and meeting notes

The exhibition creates contacts; the sourcing decision happens in follow-up. Give each open item an owner and due date.

The level of due diligence should reflect product risk, regulatory requirements, order value and relationship length. A factory audit or qualified third-party inspection can provide additional evidence about production processes, quality controls, test equipment, raw-material control, traceability, storage, packaging and capacity. Define the audit scope in advance; a factory visit is not a substitute for product-specific technical verification.
