Manufacturing Control

A clearer factory process for B2B buyers

WUHAN SUNFULL NEW ENERGY TECHNOLOGY CO., LTD. uses this factory page to show the evidence overseas buyers can request before an AC charger, DC fast charger, OCPP charger or OEM order is approved.

SUNFULL NEW ENERGY manages product delivery through defined manufacturing steps: engineering review, incoming material inspection, assembly, wiring check, software configuration, functional test, aging test, final inspection, packing review and export documentation.

For distributors, EPC contractors and fleet operators, this process helps keep repeat orders consistent. Buyers can request product photos, packing photos, serial-number records, datasheets and basic test records before shipment.

SUNFULL factory workflow
Procurement Answer

Can SUNFULL provide factory proof for AC/DC charger orders?

Yes. For an AC wallbox order, buyers normally verify enclosure finish, Type 2 / Type 1 / GB/T connector, OCPP/RFID scope, label position and packing details. For a DC fast charger order, buyers should also confirm power module configuration, CCS2/CCS1/CHAdeMO/GB/T connector scope, cooling method, test workflow, OCPP/CSMS configuration and export document package.

AC charger proof

Model photo, rated power, connector, app/RFID/OCPP scope, certificate file, label artwork and carton packing.

DC fast charger proof

Power module plan, connector standard, charging test, cabinet finish, cooling, network setup and crate packing.

Buyer action

Send power, connector, country, quantity, certificate target and OEM scope before asking for factory evidence.

Incoming Inspection

Key components are checked against the purchase specification, including enclosure, power modules, cables, connectors, PCB assemblies and packing materials.

Assembly & Wiring

Assembly teams follow product-specific work instructions for electrical layout, mechanical installation, torque checks, labeling and safety spacing.

Functional Testing

Products are tested for basic electrical function, communication, protection logic, display or app workflow, and configuration consistency before shipment.

Export Packing

Carton or crate strength, accessories, labels, user documents and packing marks are reviewed to reduce damage and customs confusion after arrival.

Factory Proof for RFQ

Evidence buyers can request before a sample or batch order

A factory page should reduce procurement risk. For EV charger and BESS buyers, the useful proof is not only a workshop photo; it is whether the exact model, test workflow, document scope and packing plan match the order.

Live video review

Request a live call to review the production area, sample charger, connector options, enclosure finish, label position, accessories and packing method before payment.

Model-specific evidence

Ask for the exact model datasheet, nameplate, connector standard, firmware/OCPP scope, rated voltage and certificate scope instead of relying on generic company claims.

Inspection records

For batch orders, buyers can request serial-number lists, basic functional test notes, packing photos and carton or crate marks before shipment release.

Export document check

Confirm invoice description, HS code reference, packing list, certificate file, label language, warranty term and destination-market requirements before final quote approval.

Buyer Route

Use the factory page together with the commercial RFQ pages

To keep SEO authority focused, SUNFULL routes factory verification back to the main buyer-intent pages instead of scattering the same sourcing questions across dozens of thin URLs.

China manufacturer page

Compare AC wallbox, DC fast charger, OCPP, certificates, OEM and export terms in one RFQ path.

View manufacturer page

Commercial charger page

Use for fleet depots, parking operators, malls, hotels, CPO sites and highway charging projects.

Plan commercial charging

OEM / private label

Use when the order needs logo, label, packaging, firmware, app language or OCPP backend parameters.

Review OEM scope

Certificates and documents

Check model scope, target market, rating label, grid standard and document package before shipment.

Factory FAQ

Factory verification questions before purchase

Use these questions when checking whether the factory page supports the exact charger model you want to source.

What factory proof can SUNFULL provide before shipment?

SUNFULL can provide model-specific photos, packing photos, serial-number records, datasheets, basic test records and export document checks when these items are requested in the RFQ.

Can buyers request a live factory video call?

Yes. Buyers can request a live video call to review production workflow, product samples, connector options, packing details, certificate scope and quotation questions before a sample or batch order.

Does factory verification apply to both AC and DC chargers?

Yes. AC projects focus on wallbox configuration, connector, OCPP/RFID and packing. DC projects also need power module, cooling, connector standard, charging test workflow and site document checks.

What should buyers send for verification?

Send product type, destination country, charger power, connector, certificate needs, order quantity, branding scope and delivery timeline so SUNFULL can prepare relevant proof instead of generic workshop photos.

Need factory evidence for your project?

Send your target product, destination country, quantity, connector standard, certification need and delivery plan. SUNFULL can prepare a focused factory proof pack and RFQ response after project-scope review.
