Case Study: Kuching Trading Company Sourcing Manager Sourcing Success
Raj Kumar Pillai, a Trading Company Sourcing Manager in Kuching, needed a charging line that property managers would approve and riders could pay for without a dedicated app. The fleet in Kuching had been charging e-bikes from wall sockets behind the office, and the landlord issued a warning after the second blown circuit.
Following a three-week sample window, Raj Kumar Pillai selected Wanlin Fire as their EV charging equipment manufacturing partner. The decision came down to OCPP conformance, real certificate files and a factory that would modify the socket count without redesigning the board.
- Export experience: the factory ships charging equipment to Southeast Asia, South Asia, Africa, Latin America and the Middle East
- Payment compliance: QR, RFID, NFC, coin and App payment modules are selected to match local payment habits and regulations
- Custom QR flows: the OEM team in Shenzhen can point the QR code to a local e-wallet landing page configured for the Malaysia operator.
The pilot covered a condo tower, a shophouse row and a market stall cluster in Kuching, and the failure data pointed to one common cause.
Problem Analysis & Field Report: Why Global Buyers Need OCPP 1.6J Smart Wallbox
Field reports from fleets show the same pattern: equipment fails where the installation plan ignored protection, grounding and payment management. A fleet owner in Kuching could not prove how many kilowatt-hours each rider consumed, so depot cost allocation was a monthly argument.
Field case: A strata committee in Kuching installed OCPP wallboxes and shared one 63A feeder across 15 charging points; the backend caps total load before the main breaker can trip.
Why it matters for global buyers:
- OCPP 1.6J compliance means the charger works with any CSMS, protecting the buyer from vendor lock-in
- Remote start / stop and configuration changes reduce truck rolls to the site
- Transaction and meter data feed billing, energy monitoring and maintenance logs automatically
- Firmware updates over the network keep the fleet compliant as protocols evolve to OCPP 2.0.1
- OCPP 1.6J gives property teams live status, start and stop control, and exportable session logs for the management office
- Firmware and charging profiles update remotely, so a fleet rule change in Malaysia applies without visiting each unit

Product Introduction: Wanlin Fire OCPP 1.6J Smart Wallbox
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.

EV Charger OEM Process: From Inquiry to Shipment
A typical Wanlin Fire OEM project begins with the target market, because voltage, certification and payment habits decide the hardware configuration. A standard OEM project then follows 8 steps:
- 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
- Select a Model Line - our team recommends suitable WL-series models according to your vehicle types (48V / 60V / 72V), site conditions and target customers
- Verify Documentation - for certified models, request and verify the relevant certificate, OCPP conformance and enclosure rating documentation files
- Confirm OEM Requirements - color, logo, payment modules, voltage, socket count, packaging and accessories
- Sample Evaluation - samples can be evaluated before mass production according to the agreed commercial terms
- Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project can proceed to production
- Quality Inspection - chargers are inspected and tested with load-bank and aging procedures according to applicable production and quality-control standards
- 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 Kuching 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): "Spare mainboards arrived within three weeks when a storm surge damaged two sites, which kept the network online."
- Raj Kumar Pillai (Trading Company Sourcing Manager, Kuching, Malaysia): "We replaced eleven different socket models with one Wanlin line, and our maintenance calls dropped by about 24%."
Frequently Asked Questions
Q: Which OCPP versions does the WL-OC support?
A: The wallbox ships with OCPP 1.6J over WebSocket, which connects to most commercial central systems. Firmware for OCPP 2.0.1 profiles is under test and can be loaded via OTA once validated for the target backend.
Q: Can the WL-OC work without a backend server?
A: Yes. Standalone mode runs auto-start or RFID authentication with local session logs. Connecting a backend later only requires entering the server URL and station ID.
Q: How do you test OCPP compatibility before shipment?
A: Our engineers register the unit on the customer CSMS sandbox, run boot notification, status notification, start / stop transaction and meter value messages, and share the log with the buyer.
Q: What leakage protection does the WL-OC carry?
A: Type A leakage detection with AC 6mA DC smoothing monitoring, plus surge and overvoltage protection. The breaker ratings are matched to the supply voltage at the specification stage.
Q: Is the WL-OC suitable for outdoor installation?
A: With the IP65 enclosure option and IK10 front cover, the wallbox handles rain, dust and curb-side knocks from -30 to 50 degrees Celsius.
