Bottom line The WL-SC6 pairs 1.5-3kWp of canopy panels with a 5-10kWh LiFePO4 buffer, keeping 6 metered sockets live through brownouts and off-grid nights. 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. The numbers that mattered netting the buyer a 36% margin against the previous supplier 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.

It looked like a routine RFQ until the buyer mentioned what the last batch cost them. Across the market, most charging complaints trace back to unmetered sockets, flat-rate billing and boards with no overload protection.
The evaluation stretched over three weekends, Ahmad Faizal selected Wanlin as their EV charging manufacturing partner. By the time the container was booked, the decision had already been validated by real riders.
In the back office, the CSMS dashboard showed all 20 ports online with live meter values, three days after installation.
It started with one return and grew into a spreadsheet of them. A village charging point wired to a long rural feeder browned out every evening exactly when demand peaked.
Field case: A village cooperative in Yangon 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:
What the pilot units had in common was a single mainboard with per-port metering and a contactor rated for real monsoon humidity.

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.
The rows below come from the buyer's own comparison notes, not from our brochure.
| 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 |
From the first sample request to the sailing date, the buyer could see each gate in writing. A standard charging station OEM project then follows 8 steps:
Buyers from three countries said the same thing in their own words.
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.
The numbers that mattered By working directly with manufacturer Wanlin, the Municipal Project Contractor team in Yangon 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.
