Case Study: Manila Delivery Fleet Electrification Manager Sourcing Success
Dewi Lestari, a Delivery Fleet Electrification Manager based in Manila, was sourcing two-wheeler charging equipment for a network that had grown faster than its charging points. The first quotes he received were for car chargers that needed 380V input, while his depots only had 220V single-phase supply.
After reviewing quotes from three countries, Dewi Lestari selected Wanlin Fire as their EV charging equipment manufacturing partner. Documentation decided it: CE / FCC / RoHS files and an OCPP 1.6J conformance statement arrived with the samples, ready for customs.
- Source factory: Wanlin Fire runs in-house SMT lines, enclosure assembly and load-bank aging racks for two-wheeler and three-wheeler chargers
- Enclosure ratings: IP54 to IP65 waterproof and dustproof enclosures with IK08 / IK10 impact options for street installation
- Private label: your brand on the enclosure, LCD screen boot logo, packaging and the mobile App name
Samples with the buyer logo were approved in 16 days, and mass production used the same components as the approved units.
Problem Analysis & Field Report: Why Global Buyers Need Solar Charging Station for Off-Grid Sites
Field reports from fleets show the same pattern: equipment fails where the installation plan ignored protection, grounding and payment management. A resort in Manila promised guests electric bike rentals, but the nearest stable grid connection was 16 days of paperwork away.
Field case: An island resort in Manila installed a solar-ready station and charged rented e-bikes entirely off-grid for 3 months before the grid permit arrived.
Why it matters for global buyers:
- Solar-ready inputs and battery buffers keep chargers working where grid hours are short
- Off-grid stations extend vehicle range windows instead of limiting routes to grid availability
- Charge controllers protect expensive battery packs from the voltage swings of weak grids
- Operators in remote areas avoid diesel generator cost for daily charging loads
- Solar-ready inputs let operators add panels and storage later instead of replacing the whole station
- Off-grid stations keep e-bike fleets moving in islands and rural provinces where the grid is thin

EV Charger OEM Process: From Inquiry to Shipment
The OEM process for a Philippines 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:
- 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
Operators who standardized on one OCPP-compatible line report shorter vendor lists and fewer site visits:
- Andre Silva (EV Charger Distributor, Sao Paulo, Brazil): "We replaced eleven different socket models with one Wanlin line, and our maintenance calls dropped by about 20%."
- Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "Riders scan the QR code and pay with the wallet they already use; we stopped explaining how to charge."
- Dewi Lestari (Delivery Fleet Electrification Manager, Manila, Philippines): "Our logo, the App name and the payment gateway were all configured before the first container left the factory."
Frequently Asked Questions
Q: How many scooters can the WL-SO charge per day?
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.
Q: What happens after several cloudy days?
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.
Q: Is the WL-SO hard to install in remote areas?
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.
Q: Can the WL-SO be monitored from the city?
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.
Q: Which battery does the WL-SO use and how is it shipped?
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.
