Project Overview
A Dutch renewable energy operator deployed Yifan YF325 Industrial LTE Routers across a network of award-winning Solar Flower EV charging stations in the Netherlands. These solar-powered chargers are installed in open outdoor locations — parking lots, marinas, and public spaces — where fiber infrastructure is unavailable or cost-prohibitive. The YF325 provides always-on 4G LTE connectivity for OCPP payment processing, remote monitoring, and energy management across all seasons.
Solar Flower EV charging stations deployed across the Netherlands — winter snow, autumn parking lots, and coastal locations
Challenge
The Solar Flower charging stations are designed for open outdoor locations where trenching fiber cables is not economically viable. The operator required:
- Always-on connectivity for OCPP 1.6/2.0 payment processing
- Remote monitoring without on-site visits
- Dual-carrier redundancy for 99.9% uptime SLA
- CE-certified hardware for EU compliance
- Wide temperature range for Dutch winter and summer conditions
Solution
The Yifan YF325 Industrial LTE Router was selected and integration-tested at the manufacturing facility before field deployment:
- Dual SIM Auto-Failover: Automatic carrier switchover in under 90 seconds — zero manual intervention
- Remote Management via RMP: Centralized monitoring, firmware updates and diagnostics without site visits
- CE / RED Certified: Full EU Radio Equipment Directive compliance for Netherlands deployment
- -35°C to +75°C Operation: Verified performance through Dutch winter conditions
- DIN-Rail Mounting: Clean installation inside Solar Flower electrical cabinet

Results
- ✓ 99.9% network uptime across all deployed stations
- ✓ OCPP payment processing runs without interruption
- ✓ Zero on-site maintenance visits required for network issues
- ✓ Dual SIM failover eliminated single carrier dependency
- ✓ Remote firmware updates deployed fleet-wide in minutes
- ✓ Deployment expanded to northern France
Solar tracking technology enables maximum solar energy capture throughout the day
