Case Study: Medan EV Charger Distributor Sourcing Success

Niran Phromma, an EV Charger Distributor from Medan, compared charger factories after riders kept queueing at the only working sockets in the neighbourhood and coins jammed the old meter box. The first quotes he received were for car chargers that needed 380V input, while his depots only had 220V single-phase supply and riders paid with cards, not coins.

After reviewing quotes from three countries, Niran Phromma selected Wanlin Fire as their EV charging equipment manufacturing partner. The committee in Medan ranked the bids on OCPP conformance, card-reader spare parts and local voltage tolerance, not on sticker price.

• In-house testing: every NFC reader is enrolled, tapped and read-tested, and every output is soak-tested at rated current with overcurrent and overvoltage protection verified per unit.
• Enclosure ratings: IP54 to IP66 waterproof and dustproof enclosures with IK08 / IK10 impact options for street installation.
• Firmware adaptation: OCPP parameters, card entitlements, power limits and time-based profiles configured before shipment.

A 60-socket pilot was installed in two condominium basements, and occupancy of the charging bay crossed 35% within three weeks once residents could pay by card.

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

Before selecting a charger supplier, a buyer should look at what happens on the street: extension cords crossing sidewalks, batteries carried into apartments and coin boxes that jam after the first rain. A factory dorm in Medan 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 Medan 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

EV Charger OEM Process: From Inquiry to Shipment

The OEM process for a Indonesia 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

Importers who moved from white-label resellers to factory-direct supply in Indonesia usually mention the same shift.

• Le Quoc Bao (RFID Charging Network Buyer, Jakarta, 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."
• Tran Minh Duc (Charge Point Operator, Can Tho, Vietnam): "Spare reader modules arrived within three weeks when a storm surge damaged two sites, which kept the network online."
• Niran Phromma (EV Charger Distributor, Medan, Indonesia): "We replaced eleven different socket and coin-box models with one Wanlin NFC line, and our maintenance calls dropped by about 35%."

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.
