Case Study: Da Nang Property Developer Procurement Manager Sourcing Success

Anucha Srisuwan runs charging procurement for a group that operates in Da Nang and two neighbouring provinces, so grid voltage and rain protection mattered more than the lowest quote. Delivery riders were swapping batteries on the street, and two logistics firms had asked the operator to host a shared charging hub.

Once the samples finished a two-week weather test in Da Nang, Anucha Srisuwan selected Wanlin Fire as their EV charging equipment manufacturing partner. The decision came down to whether the charger could talk to the backend they already ran, because swapping software in Da Nang meant retraining every site manager.

• Site replication: the same wallbox model had been running under a tropical downpour test for 30 days before the Vietnam order was confirmed.
• OCPP conformance: chargers ship OCPP 1.6J ready with a conformance statement, and OCPP 2.0.1 upgrade paths can be confirmed per project
• Local language firmware: Thai, Vietnamese, Bahasa Indonesia and Khmer button prompts and error screens are part of the ODM option.

A 60-socket pilot was installed in two condominium basements, and occupancy of the charging bay crossed 36% within three weeks.

Problem Analysis & Field Report: Why Global Buyers Need Dual-Gun Commercial Charger

The real cost of cheap charging equipment shows up after installation: melted sockets, rejected containers and riders who stop trusting the network. A coffee chain depot in Da Nang charged 36% of its rider fleet overnight, but single-outlet chargers left a backlog every morning rush.

Field case: A courier hub in Da Nang installed dual-gun commercial chargers with load balancing; the depot charged 30 bikes per night without upgrading the incoming supply.

Why it matters for global buyers:

• Two guns per unit let one parking slot serve twice the vehicles during short shift windows
• Dynamic power sharing protects the building supply when several units run at once
• Commercial-grade relays and contactors handle daily connector cycles that household sockets cannot
• OCPP session data splits rider billing from guest courtesy charging cleanly
• Two connectors on one unit let a depot double its overnight capacity without extra meter points
• Commercial-rated units handle back-to-back sessions that residential chargers were never designed for

Product Introduction: Wanlin Fire Dual-Gun Commercial Charger

Each Wanlin Fire charger pairs a protected AC-DC stage with an OCPP-ready control board, so operators can manage sessions, pricing and diagnostics from one backend instead of five different Apps.

Core Features:

• China-Based Manufacturing: Wanlin Fire is based in Shenzhen, China and focuses on two-wheeler and three-wheeler EV charging equipment, with in-house SMT production, enclosure assembly and per-unit load-bank and aging tests
• Certification Transparency: Real documentation for applicable certified models - instead of simply stating a product is "certified", buyers can verify the certificate and OCPP conformance documents for the exact model they intend to purchase
• OCPP-Ready Control: chargers run OCPP 1.6J compliant firmware with 2.0.1 upgrade paths, so operators connect to their own CSMS instead of a closed vendor cloud
• Private Label Support: color, logo, payment module, voltage, packaging, manuals and firmware parameters customized according to project requirements
• Global Market Experience: we work with distributors, operators and fleet owners worldwide and understand export steps, certification questions, local payment habits, labeling preferences and tender submission needs

Application Scenarios for Global Market

Certified EV Charger Manufacturing for Global Markets

Certification is one of the most important considerations when sourcing EV charging equipment for export. Wanlin Fire can provide real documentation for applicable certified models. Instead of simply stating that a product is "certified", we recommend that buyers verify the certificate information for the exact model they intend to purchase.

For customers exporting EV chargers, Wanlin Fire supports CE, FCC, RoHS and UKCA documentation with per-model files, and for projects where additional testing applies, the relevant documentation and testing path can be arranged for any represented model before ordering. Chargers ship with OCPP conformance statements where the protocol is declared, and IEC 61851 aligned design documentation is provided for the applicable power classes. Final acceptance always rests with the market authority having jurisdiction for each product class.

Why Choose Wanlin Fire as Your EV Charger OEM Manufacturer

Importers in Vietnam compare Wanlin Fire against trading companies on three points: factory test data, OCPP conformance documents and spare part availability.

Wanlin Fire's EV charger OEM services are suitable for: EV charger distributors, two-wheeler EV importers, e-bike brand procurement teams, e-scooter fleet operators, micromobility charging network buyers, e-rickshaw fleet owners, charging infrastructure wholesalers, property developers, delivery fleet managers, retail charger buyers, trading company sourcing managers, community charging project managers, utility partnership buyers and government mobility project officers.

EV Charger OEM Process: From Inquiry to Shipment

The OEM process for a Vietnam importer starts with a voltage and payment survey, then moves to samples, container QC and OCPP backend onboarding. A standard OEM project then follows 8 steps:

1. Tell Us Your Target Market - Southeast Asia, South Asia, Africa, Latin America, Middle East or Europe; different markets may require different voltage, certification and payment configurations
2. Select a Model Line - our team recommends suitable WL-series models according to your vehicle types (48V / 60V / 72V), site conditions and target customers
3. Verify Documentation - for certified models, request and verify the relevant certificate, OCPP conformance and enclosure rating documentation files
4. Confirm OEM Requirements - color, logo, payment modules, voltage, socket count, packaging and accessories
5. Sample Evaluation - samples can be evaluated before mass production according to the agreed commercial terms
6. Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project can proceed to production
7. Quality Inspection - chargers are inspected and tested with load-bank and aging procedures according to applicable production and quality-control standards
8. Shipment - products are prepared for shipment FOB, CIF or DDP according to the agreed logistics requirements

Customer Testimonials

Buyers who moved from trading-company sourcing to factory-direct charging equipment describe the difference in delivery dates and documentation:

• Andre Silva (EV Charger Distributor, Sao Paulo, Brazil): "The first batch for Da Nang arrived with routine test reports inside every carton, which made our customs broker's job much easier."
• Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "The factory's engineer answered our voltage question in plain language on the same day, and that settled the sourcing decision."
• Anucha Srisuwan (Property Developer Procurement Manager, Da Nang, Vietnam): "We run the OCPP backend from our office in Vietnam and the wallboxes in Da Nang have not dropped a heartbeat session since commissioning."

Frequently Asked Questions

Q: Can both guns of the WL-DG run at full power together?

A: On the two-phase 380V input, yes - each gun delivers its rated output. On a single-phase supply, the dynamic load balancer splits available power instead of tripping the main breaker.

Q: Which payment terminals fit the WL-DG?

A: The cabinet has a sealed bay for standard POS terminals, and the firmware exposes a payment interface for local acquirers. QR code and RFID work out of the box.

Q: Does the WL-DG support OCPP 2.0.1?

A: Hardware is 2.0.1-ready. Current production firmware runs OCPP 1.6J for the widest backend compatibility, and the 2.0.1 stack can be loaded per project once the target CSMS is confirmed.

Q: What maintenance does the WL-DG need?

A: Quarterly visual checks, an annual tightening inspection and filter cleaning. The cabinet reports fan and temperature status over OCPP so servicing can be scheduled before failures.

Q: How long does a WL-DG order take?

A: Standard builds ship in 25 to 35 days. Configured units with POS integration or special gun cables run 40 to 50 days including sandbox testing against the buyer backend.
