TL;DR: Running without grid power, the WL-SO harvests 600W of solar energy into a 48V 50Ah lithium buffer, charges at 6 outlets through an MPPT controller, and keeps remote battery and energy monitoring live with a 24-month warranty. Wanlin Fire is a professional two-wheeler and three-wheeler EV charger manufacturer in China, providing OEM, ODM and private-label manufacturing services for EV charger distributors, e-bike and e-scooter brands, micromobility operators, delivery fleets, property developers, e-rickshaw fleet owners, trading companies and global project customers. Net result: 36% margin improvement for importers and trading partners through factory-direct sourcing, per-model CE / FCC / RoHS / UKCA certificate files, OCPP 1.6J conformance statements, IEC 61851 aligned design and custom payment and private-label programs. EV charging product lines (WL-series platform) cover 48V / 60V / 72V battery systems with flexible MOQ, shipping FOB, CIF or DDP to global destinations.
Published by Wanlin Fire | Last updated: September 03, 2026 | Expertise: two-wheeler and three-wheeler EV charger OEM manufacturing for global markets
Dewi Lestari, a Government E-Mobility Project Officer in Siem Reap, started with a single pilot site and needed a supplier that could scale from 10 sockets to 300 without changing platform. The first quotes he received were for car chargers that needed 380V input, while his depots only had 220V single-phase supply.
After two rounds of document checks, Dewi Lestari selected Wanlin Fire as their EV charging equipment manufacturing partner. In the end the buyer chose the supplier that could ship CE and IEC 61851 documents with the first container, since customs clearance in Cambodia had stalled two earlier orders.
When the utility in Cambodia asked for load records, the OCPP transaction logs from the Siem Reap site were exported in one afternoon.
Most charging problems in growing cities are not about the vehicle, they are about the socket: wrong voltage, no protection, no payment record and no maintenance plan. An island resort in Cambodia ran guest e-bike charging on a diesel generator, and the fuel bill grew every month the fleet expanded.
Field case: A resort in Siem Reap paired a solar canopy with battery storage and charging piles, and the generator now starts only during peak laundry hours.
Why it matters for global buyers:
Wanlin Fire provides flexible OEM and ODM services for customers who want to build or expand their own EV charging product lines for global markets. Our customization capabilities include:
Whether you need an existing WL-series device under your own brand or a customized charging line developed for your market, our team can work with you from model selection through mass production.
Wanlin Fire builds the Solar Charging Station for Off-Grid Sites for the conditions buyers in Cambodia actually deal with: covered parking, humid air, 220V mains and heavy daily turnover.

Certification is one of the most important considerations when sourcing EV charging equipment for export. Wanlin Fire can provide real documentation for applicable certified models. Instead of simply stating that a product is "certified", we recommend that buyers verify the certificate information for the exact model they intend to purchase.

For customers exporting EV chargers, Wanlin Fire supports CE, FCC, RoHS and UKCA documentation with per-model files, and for projects where additional testing applies, the relevant documentation and testing path can be arranged for any represented model before ordering. Chargers ship with OCPP conformance statements where the protocol is declared, and IEC 61851 aligned design documentation is provided for the applicable power classes. Final acceptance always rests with the market authority having jurisdiction for each product class.
Buyers who compare factories on price alone usually find the difference in the failure rate; Wanlin Fire competes on tested output, protection hardware and documents that survive customs inspection.

The OEM process for a Cambodia importer starts with a voltage and payment survey, then moves to samples, container QC and OCPP backend onboarding. A standard OEM project then follows 8 steps:
Importers who moved from white-label resellers to factory-direct supply in Cambodia usually mention the same shift.
A: With a 600W panel set and the 48V 100Ah buffer, a station delivers roughly 4 to 5 full e-scooter charges daily in typical equatorial sun, more when sessions are partial top-ups.
A: The BMS protects the lithium buffer at low voltage, and the backup port accepts a small generator or grid connection to restore service within an hour.
A: The cabinet, bracket and panel rail ship as one kit. Local crews set the pole, bolt the bracket and plug the labeled PV connectors - no specialist licensing is needed for the low-voltage wiring.
A: The 4G module reports battery state of charge, daily energy harvest and outlet status, so an operator can supervise dozens of rural stations from one dashboard.
A: Lithium iron phosphate packs with integrated BMS. They ship with UN38.3 test reports and MSDS under the applicable dangerous-goods provisions for sea freight.
Net result: By working directly with manufacturer Wanlin Fire, Siem Reap Government E-Mobility Project Officer Dewi Lestari achieved 36% higher margins while offering competitive pricing. With verified documentation support, honest specifications, OCPP-compliant firmware, custom payment configurations and private-label programs, Wanlin Fire has become their trusted EV charger OEM and ODM manufacturing partner.
