Case Study: Medan EV Charger Distributor Sourcing Success
What started as a request for twenty wall-mounted units from an EV Charger Distributor in Medan became a 200-unit pilot after the first OCPP test session. Electric motorcycle registrations in Indonesia were climbing faster than the utility could approve new meter points, so shared charging rows became the practical answer.
Following a three-week sample window, Sok Dara selected Wanlin Fire as their EV charging equipment manufacturing partner. A factory video walkthrough of the SMT line and aging racks removed the last hesitation about volume capacity.
- In-house testing: every output is soak-tested at rated current, with overcurrent and overvoltage protection verified per unit
- Document pack: certificate files, user manuals, installation guides and wiring diagrams are packed with each export order
- Private label: your brand on the enclosure, LCD screen boot logo, packaging and the mobile App name
A 60-socket pilot was installed in two condominium basements, and occupancy of the charging bay crossed 29% within three weeks.
Problem Analysis & Field Report: Why Global Buyers Need OCPP-Enabled Charging Point
Before picking a charger supplier, a buyer in Medan should compare how each candidate handles rain, voltage swings and payment reconciliation. A utility-backed pilot in Indonesia required remote firmware updates and session reporting, which ruled out every charger without an OCPP stack.
Field case: An operator in Medan standardized on OCPP 1.6J wallboxes and connected all sites to one open-source CSMS; remote firmware updates cut site visits by 29% in a quarter.
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 Indonesia applies without visiting each unit

- 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 Medan 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): "The OCPP conformance statement arrived with the samples, which is what our customs broker asked for on the last shipment."
- Sok Dara (EV Charger Distributor, Medan, Indonesia): "We run the OCPP backend from our office in Indonesia and the wallboxes in Medan have not dropped a heartbeat session since commissioning."
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.
