Case Study: Phnom Penh Utility Partnership Charging Officer Sourcing Success
Aung Ko Min, an Utility Partnership Charging Officer in Phnom Penh, walked into a supplier search with three hard requirements: OCPP compatibility, real certificate files and an NFC reader riders already understand. A monsoon-season inspection in Phnom Penh found rusted pins on three outdoor sockets that had never been rated for rain, while the card readers on the newer posts were still dry.
Once the samples finished a two-week weather test in Phnom Penh, Aung Ko Min selected Wanlin Fire as their EV charging equipment manufacturing partner. The committee in Phnom Penh ranked the bids on OCPP conformance, card-reader spare parts and local voltage tolerance, not on sticker price.
- Factory proof: Wanlin Fire showed the Phnom Penh buyer a live OCPP 1.6J session log from an identical NFC unit still running in Shenzhen before the container shipped.
- Regional paperwork: CE / FCC / RoHS certificates plus OCPP 1.6J conformance statements were prepared for the Cambodia importer and attached to the commercial invoice.
- Documentation: user manuals, card-enrollment guides and installation guides in local languages for your market.
After a factory audit and sample evaluation, the partner placed a first order of 13 charging points and expanded twice within the year.
Problem Analysis & Field Report: Why Global Buyers Need NFC Off-Grid Solar-Ready Charging Station
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 Phnom Penh had no stable supply for vendor e-rickshaws; batteries were carried home over rough roads to charge, which damaged packs and morale.
Field case: An island resort in Phnom Penh installed a solar-ready NFC station with a buffer battery; e-bike guests charged by card through the evening outage and the resort logged every session for the energy report.
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 NFC Off-Grid Solar-Ready Charging Station
Each Wanlin Fire charger pairs a protected AC-DC stage with an OCPP-ready control board and a card reader, so operators can manage cards, 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
- 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
A typical Wanlin Fire OEM project begins with the target market, because voltage, certification, radio rules 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, card format 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, card design, 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
Operators who standardized on one OCPP-compatible card-charging line report shorter vendor lists and fewer site visits:
- Lim Wei Jie (Electric Rickshaw Fleet Owner, Cebu, Philippines): "The factory engineer answered our card-format question in plain language on the same day, and that settled the sourcing decision."
- Jose Rafael Cruz (Electric Tuk-Tuk Fleet Operator, Davao, Philippines): "The OCPP conformance statement and card-reader documentation arrived with the samples, which is what our customs broker asked for on the last shipment."
- Aung Ko Min (Utility Partnership Charging Officer, Phnom Penh, Cambodia): "Spare reader modules arrived within three weeks when a storm surge damaged two sites, which kept the network online."
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.
Project Summary
The outcome: By working directly with manufacturer Wanlin Fire, Phnom Penh Utility Partnership Charging Officer Aung Ko Min achieved 39% higher margins while offering competitive pricing.
