Concox Solar Powered GNSS Tracker LL303 4G LTE GPS BDS

Concox LL303 is a solar-powered GNSS tracker with 4G LTE connectivity and multi-system positioning (GPS + BDS + LBS + Wi‑Fi). Built for long-term outdoor monitoring of vehicles, trailers, vessels and equipment, the device combines a 10,000 mAh industrial Li‑polymer battery, an integrated solar panel and IP68 protection to provide extended standby and reliable operation in harsh environments. LTE communication with GSM (2G) fallback, BLE5.0 configuration and multiple working modes make the LL303 suitable for fleet and asset management deployments. A nano‑SIM with data is required (sold separately).

Advantages

The tracker offers multi-constellation positioning and Wi‑Fi/LBS assistance for improved location accuracy, LTE Cat1/Cat M1/Cat NB2 connectivity with GSM fallback, and a robust IP68-rated enclosure for outdoor use. Long battery life (up to 2 years in battery‑saving mode) is supported by solar recharge and a 10,000 mAh industrial battery; charging is via magnetic USB (5V/2A). Integrated sensors (accelerometer, temperature and humidity, Hall effect) plus tamper and vibration alerts enable event-triggered notifications for asset security and condition monitoring. The unit is compatible with common tracking platforms and can be configured via the Tracksolid app.

Suitable for

• Monitoring construction vehicles and heavy equipment
• Tracking trailers, containers and mobile assets
• Remote asset and vessel tracking where long standby is required
• Deployments needing rugged, waterproof (IP68) hardware

How to use

Insert a nano‑SIM card with a data plan (sold separately) into the device, attach the LL303 to the asset using the included magnetic base and screws, and connect the USB magnetic cable for initial charging if needed. Configure the tracker and monitoring parameters via the supported Tracksolid platform on Windows, Android or iOS, or through your chosen GNSS tracking platform. Select the appropriate working mode (GPS/tracking/power saving) depending on required update frequency and battery life, and enable alerts for tamper, vibration, temperature/humidity and low battery as needed.

Usage recommendations

For reliable solar charging, mount the device so the solar panel receives direct sunlight where possible; verify cellular coverage and choose LTE with GSM fallback. Use power‑saving mode for long unattended deployments, perform initial full charge using a 5V/2A charger, and periodically check app-reported sensor and battery status. Purchase and activate a nano‑SIM with a data plan before deployment.
