Case Study: Cebu Municipal Project Contractor Sourcing Success
Most distributors start with price. This one started with a complaint log. Importers are consolidating charging SKUs with fewer factories that can document OCPP conformance and IP ratings.
Once the field units logged 5,000 charging sessions, Lim Wei Sheng selected Wanlin as their EV charging manufacturing partner. The buyer admitted the deciding factor was a supplier who answered protocol questions in hours, not weeks.
- every station completes a scripted OCPP session test against a live CSMS before it is boxed
- UL, PSE and market-specific filing support is available for buyers serving North America and Japan
- OCPP builds support buyer-specified CSMS endpoints, security profiles and custom DataTransfer messages
Standing in the depot, the buyer ran a full 12-port load while the site breaker held and the display cycled port statuses.
Problem Analysis & Field Report: Why Global Buyers Need 7kW Dual Socket Wallbox Charger
Nobody flagged it at the packing station; the market flagged it first. A condo buyer watched an OTA update brick a wallbox and waited six weeks for the importer to ship a replacement board.
Field case: A shop owner in Cebu replaced an import wallbox that tripped its RCD on every storm. The WL-WB7 shipped with a witnessed trip-time record and surge-rated input, ran a full wet season without a nuisance trip, and the shop added a second unit for the delivery bay.
Why it matters for global buyers:
- nuisance RCD trips and dead WiFi zones are the top wallbox complaints
- the fix was verified trip-time records, surge-rated inputs and 4G fallback
- signed OTA with rollback separates fleet-safe firmware from the rest

Certified EV Charging Manufacturing for Global Markets
Buyers who ship containers of charging stations need more than a price list. The production and QC flow below is what lets a distributor open a carton and trust what is inside:
- every station completes a scripted OCPP session test against a live CSMS before it is boxed
- UL, PSE and market-specific filing support is available for buyers serving North America and Japan
Lot samples from every production run are measured for metering accuracy, protection trip times and enclosure sealing before the cartons are sealed, and the numbers are recorded per batch. A buyer can request those records with any order.

EV Charging OEM Process: From Inquiry to Shipment
Moving from first contact to a sealed container took a sequence the buyer could follow in writing. A standard charging station OEM project then follows 8 steps:
- Tell Us Your Target Market - Southeast Asia, the Middle East, Europe, North America, Africa or Latin America; each market may require different certifications, socket standards, voltage classes and manual languages
- Select a Model Line - our team recommends WL-series platforms for your channel and price band, or works from a reference unit you send
- Verify Documentation - request certificate files, OCPP conformance logs and test reports for the exact model before you commit
- Confirm Customization - cabinet colors, logo, firmware behavior, tariff logic, payment flows and packaging
- Sample Evaluation - verify meter accuracy, load balancing and CSMS integration on real samples before scaling
- Confirm Production - after specifications, commercial terms and OEM details are locked
- Quality Inspection - lot samples are tested and every finished station passes hipot, trip-time and burn-in racks before packing
- Shipment - cartons leave FOB, CIF or DDP according to the agreed logistics terms
