Case Study: Denpasar Utility Partnership Charging Officer Sourcing Success

The buying team in Denpasar had approved a European wallbox brand when the finance director asked how NFC card readers would be serviced from Indonesia; that question reopened the sourcing file. The distributor had lost two container deals because the factory could not provide OCPP conformance statements and card-reader documentation before the payment deadline.

Once the samples finished a two-week weather test in Denpasar, Somsak Ratanawong 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 Denpasar meant retraining every site manager.

• Capacity control: production slots are confirmed before the order, and pre-shipment inspection photos are shared batch by batch.
• 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.

Load testing at the factory showed every outlet holding rated current for four hours, which became the deciding factor in the audit report.

Problem Analysis & Field Report: Why Global Buyers Need 20-Outlet EV Charging Cabinet

The fastest way to filter suppliers in Indonesia is to ask for an OCPP session log, a card-reader test report and a routine load report, not a brochure. A factory dorm in Denpasar banned e-bike charging indoors after a battery fire nearby, leaving 200 workers with no way to charge their commuter bikes.

Field case: A worker dormitory in Denpasar used the cabinet card log to cap each resident at one charge per night, ending the practice of hogging ports for friends.

Why it matters for global buyers:

• High port counts charge an entire dormitory or staff fleet from one engineered supply point
• Per-port breakers and over-temperature shutdown isolate a failing battery instead of taking down the row
• Card billing recovers electricity cost and caps how often each account can charge
• Outdoor-rated cabinets move charging out of corridors and lift lobbies where fire risk concentrates

Product Introduction: Wanlin Fire 20-Outlet EV Charging Cabinet

The 20-Outlet EV Charging Cabinet is assembled in the Shenzhen factory with an ISO 14443A NFC reader and IP54-level sealing as standard, which is why property teams in Denpasar install it in open car parks.

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 EV charger OEM process starts with a short qualification call about vehicle types, voltage, site conditions and the card or wallet payments used in your market. 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

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

• Nur Aisyah Hassan (Shopping Mall Facility Buyer, Surabaya, Indonesia): "The first batch for Surabaya arrived with routine test reports inside every carton, which made our customs broker job much easier."
• Budi Santoso (Property Developer Procurement Manager, Kuala Lumpur, Malaysia): "Spare reader modules arrived within three weeks when a storm surge damaged two sites, which kept the network online."
• Somsak Ratanawong (Utility Partnership Charging Officer, Denpasar, Indonesia): "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: Why choose a cabinet over several single sockets?

A: A cabinet concentrates metering, protection and payment in one enclosure on one feeder, which is cheaper to install and maintain than wiring many individual smart sockets across a large parking area.

Q: What is the largest cabinet available?

A: The 30-outlet model runs on a three-phase feed and is built for estate courts and factory sheds. Bay current is set per outlet, so a cabinet can mix 5A, 10A and 13A bays.

Q: How do we top up resident cards?

A: Residents pay by QR or bank transfer and the operator adds credit to the card account from the dashboard. The cabinet itself needs no cash handling.

Q: Can the cabinet report to a government or utility platform?

A: Yes, through the OCPP 1.6J connection. Session, meter and status data export in standard format for subsidy, reporting or audit requirements.

Q: What protection is built in?

A: Each outlet has overcurrent and leakage protection, and the cabinet has a master breaker sized to the declared feeder. Surge protection is included on the input stage.
