TopFlyTech TLP2-SFB — Large Solar-Powered LTE Asset Tracker for Containers, Trailers and Outdoor Equipment

The TopFlyTech TLP2-SFB is a solar-powered LTE Cat M1 asset tracker designed for long-term outdoor deployment where mains or vehicle power is unavailable. Combining a large 9,600 mAh rechargeable battery with an integrated solar panel, it sustains continuous operation for months — and indefinitely in adequate sunlight — making it the ideal fit for container tracking, trailer monitoring, and unmanned outdoor asset management. Available from UK stock, dispatched from our London warehouse.

Overview

The TLP2-SFB connects via LTE Cat M1 and EGPRS across a broad range of international frequency bands, with multi-constellation GNSS — GPS, Glonass, Galileo, and BeiDou — delivering position accuracy under 2 metres CEP. Real-time location updates can be as frequent as every 3 seconds, and up to 49,000 location points are stored in an internal buffer when the device is out of network coverage, ensuring no data is lost in remote or underground environments.

The device is built around a 9,600 mAh Li-Polymer rechargeable battery that is continuously replenished by the solar panel, extending battery life to months without solar input and indefinitely in normal outdoor conditions. A physical power switch, dual light sensors (front and back), and a built-in temperature sensor add further operational control and environmental awareness directly from the unit.

Key Features

• Solar Powered with Long-Life Battery — Integrated solar panel continuously recharges the 9,600 mAh Li-Polymer battery. Battery alone lasts months without any solar input, delivering sustainable, maintenance-free operation for outdoor assets.

• Real-Time and Buffered Location — Location updates as frequent as every 3 seconds in real time. Up to 49,000 points stored in buffer when out of network coverage, with automatic upload on reconnection.

• IP67 Waterproof and Dustproof — Tested in a 5-metre water pressure environment for 15 hours. Fully sealed against rain, mud, dust, and pressure washing for year-round outdoor use.

• BLE 5.0 Sensor Compatibility — Works with TopFlyTech's BLE temperature and humidity sensor (TSTH1-B), temperature and door sensor (T-Sense), and wireless relay (TSR1-B), enabling cold chain monitoring, door status tracking, and remote control without additional wiring.

• Movement Alerts — Configurable alerts triggered on asset moving and parking events, enabling immediate notification when an unscheduled movement is detected.

• Removal Alerts — Light sensors on front and back of the device detect when it is removed from the asset and send an immediate tamper alert to the server.

• Geofencing — Supports up to 64 internal geofence zones with entry and exit alerting.

• Easy No-Wire Installation — Mounts via magnet, screws, polyurethane adhesive, or heavy-duty tape. No vehicle wiring or specialist tools required.

• Built-In Temperature Sensor — Monitors ambient temperature directly from the device without additional accessories.

• FOTA Support — Remote firmware updates over the air keep the device current without on-site visits.

• Compatible BLE Accessories (H2)

• The TLP2-SFB works seamlessly with TopFlyTech's range of BLE IoT accessories to extend its monitoring capability:

• TSTH1-B — BLE 5.0 temperature and humidity sensor for cold chain and refrigerated cargo monitoring.

• T-Sense — BLE 5.1 combined temperature and door status sensor, ideal for container and trailer door monitoring.

• TSR1-B — BLE 5.0 wireless relay for remote output control.

• T-Button — BLE key fob and panic button for driver or lone-worker safety applications.

• T-Relay — BLE 5.2 hardwired relay for vehicle or equipment control.

Technical Specifications

Frequently Asked Questions

How long does the battery last without sunlight?

The 9,600 mAh Li-Polymer battery lasts for months without any solar input, depending on reporting frequency. In normal outdoor conditions with regular sunlight, the solar panel sustains the device indefinitely.

Is the TLP2-SFB fully waterproof?

Yes. It carries an IP67 rating, certified in a 5-metre water pressure environment for 15 hours. It is designed for permanent outdoor mounting on containers, trailers, and plant equipment.

Can it monitor temperature and door status?

Yes. Via BLE 5.0, it is compatible with the TopFlyTech TSTH1-B temperature and humidity sensor and the T-Sense temperature and door sensor, enabling full cold chain and cargo monitoring without additional wiring.

How is the device installed?

The TLP2-SFB mounts via magnet, screw, polyurethane adhesive, or heavy-duty tape using the included installation panel. No vehicle wiring or specialist tools are required.

What happens if the device is removed from the asset?

Dual light sensors on the front and back of the unit detect changes in light exposure caused by removal and immediately send a tamper alert to the server.

Does it store data when out of signal coverage?

Yes. Up to 49,000 location points can be saved in the internal buffer when the device is out of network coverage. Data is automatically uploaded to the server when connectivity is restored.

Does it support geofencing?

Yes. The TLP2-SFB supports up to 64 internal geofence zones with configurable entry and exit alerts.
