Suntech - ST4955 Features

This page provides a public feature overview of the Suntech ST4955 and how its capabilities are presented when used with Plaspy. It summarizes the ST4955’s practical functions for real world deployments, explains the types of telemetry the device can provide, and describes how Plaspy can display location, movement, and sensor data for operational visibility.

Exact feature availability and behavior depend on the device firmware, hardware revision, installed options, and manufacturer implementation. Solar charging, battery capacity options, optional Bluetooth and sensor bundles, and regional cellular banding can change how the ST4955 performs in a particular deployment, so use this page for general guidance and verify device specifics against manufacturer documentation.

Feature Overview​

The ST4955 is designed for long term outdoor monitoring with resilient cellular connectivity, high sensitivity GNSS, and low power operation. It is intended for assets and equipment that need persistent location awareness and environmental telemetry in harsh conditions.

  • Solar powered design with internal Li ion battery options for extended autonomous operation outdoors.
  • Multi network cellular connectivity including LTE Cat M1 and NB IoT with EGPRS 2G fallback for resilient telemetry.
  • High sensitivity 56 channel u blox GNSS with SBAS support for accurate positioning in challenging environments.
  • Ultra low power modes and configurable reporting to support multi month deployments depending on usage.
  • Optional Bluetooth sensors and a suite of environmental inputs including temperature, humidity, light, barometric pressure, and 1 wire probe support.
  • Remote firmware upgrades and standard TCP UDP transport to simplify device management at scale.

Core Features of Suntech - ST4955​

  • Solar charging architecture plus internal Li ion battery options (5,200 mAh, 7,800 mAh, 10,050 mAh) for prolonged field life.
  • Cellular connectivity on LTE Cat M1 and NB IoT with EGPRS 2G fallback to maintain connectivity across differing network conditions.
  • 56 channel u blox GNSS receiver with SBAS support and typical positioning accuracy for precise location reporting.
  • Ultra low power operating modes that enable multi month or longer deployments depending on reporting interval and sensor use.
  • Built in accelerometer reporting movement and impact events for theft detection and movement alerts.
  • Optional BLE for local sensors and beacon support plus environmental sensor inputs including temperature, humidity, light, barometric pressure, and 1 wire temperature probe support.
  • Rugged enclosure and environmental certifications designed for outdoor use, with variants that affect ingress protection and sensor options.
  • Over the air firmware update support and remote configuration via standard telemetry channels.

How These Features Work with Plaspy​

Plaspy ingests the ST4955 telemetry and presents it alongside other fleet and asset data so teams can monitor location, condition, and device health from a single interface. The platform aggregates GNSS fixes, accelerometer events, and sensor streams into map views, alerts, and historical reports.

  • Real time location and breadcrumb history displayed on maps for tracking and recovery operations.
  • Movement and impact events derived from the accelerometer surfaced as alerts and timeline events within Plaspy.
  • Environmental sensor telemetry such as temperature and humidity shown in charts, telemetry tables, and event rules for condition monitoring.
  • BLE sensor data and 1 wire probe readings available where the device is fitted and configured, enabling localized telemetry to appear in Plaspy.
  • Remote firmware update status and device health indicators presented to support fleet maintenance and lifecycle planning.

Typical Use Cases​

  • Long term asset tracking for non powered equipment where solar charging and low standby draw reduce visits for battery replacement.
  • Real time tracking of trailers, rental equipment, and off road vehicles that require persistent location telemetry.
  • Anti theft and recovery workflows that use movement detection and continuous GNSS tracking to locate moved assets.
  • Remote site and heavy equipment monitoring in construction, mining, or agricultural environments where rugged packaging matters.
  • Environmental condition monitoring for sensitive assets using built in and optional sensors with historical telemetry.
  • Scenarios that combine location feeds with other operational data in Plaspy for consolidated oversight.

Feature Availability Notes​

  • Feature sets may vary by firmware version and updates; capabilities available today can change with future firmware releases.
  • Hardware revisions and optional configurations affect which sensors and battery options are present on a given unit.
  • Regional cellular band support and network availability determine how LTE Cat M1, NB IoT, and 2G fallback behave in different markets.
  • Enclosure rating and sensor packing can vary by model variant for example IP67 versus IP65 where humidity sensors are fitted.
  • Installation and exposure to sunlight, mounting orientation, and cabling influence solar charging performance and autonomous runtime.
  • Always consult the manufacturer datasheet and release notes to confirm exact technical specifications for a specific serial number or production batch.

Why Use Plaspy with These Features​

Using the Suntech ST4955 with Plaspy gives organizations a practical way to combine long term outdoor tracking with condition telemetry and device lifecycle management. Plaspy brings GNSS fixes, accelerometer events, environmental sensor streams, and remote device status together so operations teams can monitor assets, receive alerts, and generate reports without switching between systems.
