📡 Product: NR100 V2 5G Industrial Router
🔐 Application: Remote Control & Backup Connectivity
📅 Year: 2025
“We are using the NR100 V2 as a switch and as a controller for the whole system. The 5G modem in it gets used as backup if the primary connection fails for any reason. It also controls (via RS232) a relay that can be used to remotely power cycle various components.”
— Solar Energy Operator, United States
The Challenge
Solar power plant operators need reliable remote management for distributed energy infrastructure. When primary network connections fail, manual on-site intervention is costly and time-consuming — especially for remote installations.
The system also requires precise remote control of power cycling for various components via serial interface, integrated with existing relay infrastructure.
The Solution
The Yifan NR100 V2 5G Industrial Router was deployed as the central network switch and system controller, consolidating multiple functions into a single industrial-grade device.
Primary / Backup Connectivity
5G modem provides automatic failover backup when primary connection fails — zero manual intervention required.
RS232 Serial Relay Control
Router controls a relay via RS232 port, enabling remote power cycling of system components from anywhere in the world.
Industrial-Grade Reliability
Operates in outdoor enclosure under direct sunlight. Wide temperature range −35°C to +75°C ensures year-round operation.
Centralized Control
Single device replaces multiple components — acts simultaneously as network switch, system controller, and 5G backup modem.
