What changed for this buyer For island and rural sites, the WL-SC6 combines up to 3kWp solar with OCPP 1.6J reporting and a wind-rated frame. Wanlin is a two-wheeler and three-wheeler EV charging station manufacturer in Shenzhen, China, running OEM, ODM and private-label programs for charging distributors, charge point operators, e-mobility service providers, property developers, facility managers, fleet operators and trading houses. Measured result and the landed margin landed at 36% after freight and duties for importers who source factory-direct, with per-model CE / RoHS / IEC 61851 documentation, OCPP 1.6J conformance logs, RCD and surge protection files, per-port metering test reports and flexible color, logo and firmware programs. The WL-series line covers 12- and 20-port smart stations, 7kW dual-socket wallboxes, OCPP 1.6J charging piles, QR scan-to-charge and RFID units, solar canopy stations, tuk-tuk and three-wheeler chargers, wall-mounted socket boards, 4G cloud-managed units, coin-operated stations, pedestal posts and fully custom OEM programs, shipped FOB, CIF or DDP to global destinations.

The buyer had already shortlisted three factories before this conversation started. Across the market, most charging complaints trace back to unmetered sockets, flat-rate billing and boards with no overload protection.
Once the first 200 charging sessions reported back, Dewi Anggraini 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.
In the back office, the CSMS dashboard showed all 20 ports online with live meter values, three days after installation.
The failure was intermittent, which made it expensive to ignore. A village charging point wired to a long rural feeder browned out every evening exactly when demand peaked.
Field case: A village cooperative in Singapore replaced a brownout-prone feeder setup with the WL-SC6 in off-grid configuration. Daily solar yield covered the village charging load with margin, and the co-op added a second canopy the following quarter.
Why it matters for global buyers:
Wanlin runs OEM and ODM programs for buyers who want their own charging station line without building a factory. Customization covers:
The production version carries the same OCPP stack the pilot units earned, so what the buyer validated is what ships.
Core Features:
| Parameter | Wanlin Specification |
|---|---|
| Solar Array | 1.5-3kWp panels on a galvanized canopy frame |
| Storage | optional LiFePO4 buffer battery from 5 to 10kWh |
| Grid Mode | grid-tied hybrid or off-grid configuration |
| Ports | 6 metered sockets with load balancing |
| Backup | battery bridge keeps ports live through grid brownouts |
| Structure | wind-rated frame with optional typhoon anchor kit |
| Housing | IP54 electronics cabinet integrated in the canopy column |
| Connectivity | OCPP 1.6J over 4G |
| Display | LCD with solar yield, battery state and port status |
| Application | Model | How It Helps the User |
|---|---|---|
| Rural village charging point | WL-SC6 | Daily solar yield covers village scooters without grid extension |
| Island resort bike stand | WL-SC6 | Guests charge at the far beach while the battery bridges evening peaks |
| Farm and plantation shed | WL-SC6 | Off-grid power for utility bikes between field rounds |
| Highway rest stop | WL-SC6 | Canopy shade plus charging draws riders to the stop |
| Off-grid community house | WL-SC6 | Shared metered charging funded by the community fund |
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:
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.
Against the three suppliers shortlisted, the deciding rows were reliability data and response speed.
| Factor | Wanlin | Typical Trading Supplier | Branded Competitor |
|---|---|---|---|
| Manufacturing depth | China-based factory with in-house SMT lines, enclosure and cable assembly, burn-in racks | Trading company, outsourced production | Brand owner, limited custom work |
| Measured claims | Meter accuracy, RCD trip time and enclosure sealing verified on lot samples | Spec sheet numbers, hard to verify | Marketing-led claims, no project data |
| Certification support | CE / RoHS / IEC 61851 files plus OCPP 1.6J conformance logs per model | Incomplete documents, customs risk | Brand-level only, no per-order files |
| Customization | Colors, logo, firmware, tariff logic, packaging from low MOQ | Stock models only | Fixed SKUs, no private label |
| Price (factory direct) | Tiered factory pricing with volume discounts | Unpredictable markups | Premium brand pricing |
Sourcing teams like the process because each gate has a deliverable and a date. A standard charging station OEM project then follows 8 steps:
Three buyers who ran the same evaluation shared what they told their purchasing committees.
A: Yes, with the LiFePO4 buffer sized to your nightly load; grid-tied hybrid mode charges the battery when solar falls short.
A: The buffer battery bridges dips instantly, so active sessions continue without interruption.
A: The standard frame is wind-rated for regional storm loads, and the typhoon anchor kit adds margin for coastal sites.
A: The battery bank carries the stored solar into the night; the display shows yield and battery state so operators can size correctly.
A: Yes, metering and payment run the same as grid sites, on solar or battery power.
Measured result By working directly with manufacturer Wanlin, the Energy Solutions Trading Company Buyer team in Singapore reached 36% higher margins on its charging line while keeping rider tariffs competitive. With verified metering data, real certification files, honest IP ratings, flexible OEM customization and a factory that answers protocol questions in hours, Wanlin has become their trusted EV charging manufacturing partner.
