Best Off-Grid Two-Wheeler EV Charger Manufacturer | Can Tho, Vietnam - CE RoHS Wanlin

Case Study: Can Tho Property Developer Procurement Manager Sourcing Success

Cheng Han Wei, a Property Developer Procurement Manager in Can Tho, started with a single pilot site and needed a supplier that could scale from 10 card sockets to 300 without changing platform. Delivery riders were swapping batteries on the street, and two logistics firms had asked the operator to host a shared card-gated charging hub for the neighbourhood.

After reviewing quotes from three countries, Cheng Han Wei selected Wanlin Fire as their EV charging equipment manufacturing partner. In the end the buyer chose the supplier that could ship CE and IEC 61851 documents with the first container, since customs clearance in Vietnam had stalled two earlier orders.

  • Factory proof: Wanlin Fire showed the Can Tho buyer a live OCPP 1.6J session log from an identical NFC unit still running in Shenzhen before the container shipped.
  • 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.

Field engineers in Can Tho mounted the units, enrolled the first batch of NFC cards, tested QR fallback payment, and left the property team with a one-page operating checklist.

Problem Analysis & Field Report: Why Global Buyers Need Off-Grid Two-Wheeler EV Charger

The real cost of cheap charging equipment shows up after installation: melted sockets, rejected containers and riders who stop trusting the network because the payment reader failed twice. A rural market in Can Tho had no stable supply for vendor e-rickshaws; batteries were carried home over rough roads to charge, which damaged packs and morale.

Field case: A rural cooperative in Can Tho ran a solar-charged NFC station for vendor trikes and used the card data to show the utility that daytime charging demand justified a grid connection.

Why it matters for global buyers:

  • A solar-ready station keeps charging available when the grid drops, which matters in touristic and rural areas
  • MPPT input lets operators add panels without replacing the charging hardware later
  • Card billing on an off-grid site still produces the records needed to justify grid investment
  • Buffer storage smooths solar output so charging does not stop every time a cloud passes

Product Introduction: Wanlin Fire Off-Grid Two-Wheeler EV Charger

Wanlin Fire builds the Off-Grid Two-Wheeler EV Charger for the conditions buyers in Vietnam actually deal with: covered parking, humid air, 220V mains and heavy daily card turnover.

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
  • NFC / RFID Card Payment: ISO 14443A compatible readers accept MIFARE-family and common ISO cards, with card enrollment, blocking and tariff control managed from the operator backend
  • 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, card design, 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

EV Charger OEM Process: From Inquiry to Shipment

The OEM process for a Vietnam importer starts with a voltage, card format 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, card format 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, card design, 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

Operators who standardized on one OCPP-compatible card-charging line report shorter vendor lists and fewer site visits:

  • Chanrithy Meas (Utility Partnership Charging Officer, Siem Reap, Cambodia): "Our logo, the App name, the card design and the payment gateway were all configured before the first container left the factory."
  • Cheng Han Wei (Charge Point Operator, Ho Chi Minh City, Vietnam): "Spare reader modules arrived within three weeks when a storm surge damaged two sites, which kept the network online."
  • Cheng Han Wei (Property Developer Procurement Manager, Can Tho, Vietnam): "The OCPP conformance statement and card-reader documentation arrived with the samples, which is what our customs broker asked for on the last shipment."

Frequently Asked Questions

Q: Can the WL-NOS run without any grid connection?

A: Yes, when paired with panels and the optional battery buffer. The station manages the solar input, stores surplus and releases power for charging sessions; grid connection is optional where available.

Q: How does billing work on an off-grid station?

A: The NFC reader still meters each session and credits the operator account, so a resort or community hall can recover the cost of the solar system over time.

Q: What size solar array is recommended?

A: For a typical 1000W charging station with a 5kWh buffer, a 1.5kW to 2kW panel array covers daily e-bike demand in tropical sun. Wanlin Fire shares a sizing sheet per site.

Q: Can the station switch between solar and grid automatically?

A: Yes. When both sources exist, the controller prefers solar and draws from the grid only when the buffer is low, which maximizes the renewable share.

Q: Is the station weatherproof for coastal sites?

A: The enclosure is IP54 to IP65 and the connector area is sealed for salt-air locations. Coastal projects should confirm the site distance from shore at ordering.
