Cloud Platform: Web dashboard and mobile app for remote monitoring and control
Applications:
Large-scale solar street light networks
Smart city lighting infrastructure
Campus and park lighting systems
Remote area electrification
Industrial solar installations
Rural roadway lighting
Installation Instructions:
For safety, follow this connection sequence:
Connect load (controller remains inactive)
Connect battery (controller starts if voltage >9V for 12V systems, >18V for 24V systems)
Connect solar panel (ensure open-circuit voltage within limits)
Connect 4-pin cable between solar controller and NJ-iot403L module
Attach antenna (avoid metal contact/enclosed metal spaces)
Why Choose NJ-iot403L?
