Topflytech is a Chinese GPS manufacturer with a specific focus that most competitors don't share: ultra-long operational life through solar power harvesting. Their TLD1-A and TLD2-A devices combine a modest battery with a photovoltaic solar panel that recharges during daylight hours, enabling operational lifetimes measured in years rather than months — without any battery replacement. For assets deployed in outdoor environments where battery access is impractical, this is a meaningful engineering differentiator. Connect Topflytech devices to GoAndTrack and get AI-powered asset intelligence on your longest-duration deployments.
The Solar-Battery Energy System
Understanding Topflytech's approach to battery life requires understanding the solar harvesting architecture — because it changes how you think about reporting intervals and operational planning.
TLD1-A Energy System: How It Works
Topflytech Device Range
TLD1-A
The solar asset tracker. 4G LTE, integrated solar panel, 7,200 mAh battery, IP67, magnetic mount. Primary deployment: trailers, containers, shipping equipment in outdoor environments. 3–5 year operational target with good solar exposure.
TLD2-A
Enhanced solar model with larger panel area. Improved charging in lower-light conditions. Additional I/O for external sensor connection. Suited to Northern European and less sunny deployment environments where TLD1-A may not harvest sufficiently.
TLP1-LB
Personal/parcel tracker without solar. 4G LTE, compact, designed for shipment-level tracking rather than long-duration asset deployment. Competitive with Queclink GL300 at similar price point and similar APAC market positioning.
TLP2-SB
Solar parcel tracker — the smart label form factor with solar harvesting. Unusual combination: label-style deployment with solar-assisted battery life. Targets reusable packaging and high-value parcel tracking where label form is important but battery replacement is undesirable.
Connecting Topflytech to GoAndTrack
Identify Protocol (Topflytech or GT06-Compatible)
Topflytech devices use their own protocol on some models, and GT06-compatible variants on others — particularly the TLP1-LB parcel range. Check Traccar's device database for your specific model. If listed as GT06, use GoAndTrack's GT06 endpoint. If listed as Topflytech protocol, use the Topflytech-specific endpoint.
Configure Server Address
Topflytech devices accept server configuration via SMS command or the Topflytech Configuration Tool (Windows application). For the TLD1-A: update the server IP and port in the configuration tool's GPRS settings section, or send the SMS server command to the device's SIM number. Apply over USB during initial deployment for bulk configuration.
Optimise Reporting Interval for Solar Life
For solar-powered deployments, GoAndTrack recommends a balanced interval: 60 minutes while stationary (preserves battery for overcast periods), 15–30 minutes while in motion (active tracking needed). This balance lets solar harvesting exceed consumption during typical outdoor daylight hours while maintaining meaningful tracking frequency.
Configure Solar-Aware Mission Control
Set battery alerts at conservative thresholds for solar devices: 40% warning (not 30% as for standard battery devices) — solar devices with declining battery are likely experiencing reduced solar harvesting, not just battery depletion. The trend matters more than the threshold. Mission Control's predictive battery trending flags charging problems before battery depletion occurs.

The honest recommendation: for deployments in consistently sunny climates (Middle East, Southeast Asia, Africa, Southern Europe, Latin America), Topflytech's solar harvesting is a genuine cost-saving advantage — no battery replacement logistics, no field team visits for power management. For Northern European or high-latitude deployments with limited winter sun, Digital Matter's Oyster3 on LTE-M offers more reliable long-term battery life without the solar harvesting dependency.
Key Takeaways
- Topflytech TLD1-A's solar-assisted battery system delivers 3–5+ year operational life in outdoor sunny deployments — a genuine cost advantage over pure-battery alternatives for assets in appropriate climates
- Solar harvesting only works with outdoor sun exposure: GoAndTrack's predictive battery trend monitoring identifies TLD1-A units experiencing inadequate solar charging before battery depletion occurs, enabling proactive redeployment
- Topflytech devices connect to GoAndTrack via native protocol or GT06 endpoint (model-dependent) — check Traccar's device database for your specific model's protocol identification
- Solar-aware Mission Control configuration — warning threshold at 40% rather than 30%, trend monitoring rather than static threshold — is the correct alert strategy for solar devices where declining battery indicates a harvesting problem, not just consumption
- The geographic recommendation: Topflytech TLD1-A for consistently sunny climates (Middle East, APAC, Africa), Digital Matter Oyster3 for Northern European and high-latitude markets — GoAndTrack manages both in one unified platform for global operations
