Empowering Connectivity in Remote Frontiers

SG50 facilitates connectivity in remote areas, combining solar power, a built-in battery, 4G communication, and advanced remote management. It enables wire-free deployment and independent operation in challenging environments.


Towards Massive Connectivity for IoT Deployments

8 Channels    |    2000 End-Nodes    |    Up to 15 km Communication Range

Global Frequency Plans (RU864/IN865/EU868/US915/AU915/KR920/AS923-1&2&3&4)

Harness the Sun's
Power Anywhere

SG50 uses a 30W standard solar panel (with an optional 45W upgrade) to capture solar energy, simultaneously powering the device and recharging the internal battery in ample sunlight. It dynamically adjusts the charging current according to battery temperature to optimize solar energy usage and extend battery life.

Reliability Without Sunlight, Always Connected

SG50 ensures uninterrupted operations at night or during cloudy periods with its built-in battery. It features a reliable 25Ah internal battery, ensuring typical operation for up to 4 days without sunlight.

Low Power
Consumption Design

  • Typical Power Consumption: 0.8w
  • Data Package Filter: This feature filters out invalid packages, effectively reducing unnecessary power and cellular usage.
  • Smart WiFi Control: It offers automatic WiFi shutdown during low solar power, reactivation on battery charging, and scheduled WiFi control for battery efficiency.

High Reliability in
Harsh Conditions

  • Ingress Protection: IP67
  • Operating Temperature: -30°C to +70°C
  • Battery Charging Temperature: -20°C to +50°C
  • Low-Temperature Battery Heating to Maintain Normal Operation

Wireless Deployment
with 4G Connectivity

Whether in remote areas or cost-sensitive locations, 4G wireless deployment reduces Ethernet wiring expenses and enhances convenience.

Remote Management and
Automatic Configuration

SG50 works with new Milesight management platform, which integrates LNS (LoRaWAN® Network Server). It enables automatic configuration file retrieval when the device is online, and simplifies remote configuration and updates.

Truly Wire-free Deployment and Operation

SG50 combines solar power, a built-in battery, 4G wireless communication, and remote management to enable completely wire-free deployment and independent operation in remote and challenging locations.

Effortless Adaptation,
Solar Panel or Not

SG50 is also well-suited for non-solar-panel applications, such as smart streetlights. The SG50 is powered and its internal battery is charged at night when streetlights are on, running on the internal battery during the day when streetlights are off.

LoRaWAN® Based

  • Penetrating Signals: data transmission range up to 2 km in urban areas and 15 km in rural areas
  • High Compatibility: compliant with standard LoRaWAN® sensors and network servers

Listen Before Talk

SG50 supports Listen Before Talk (LBT), enabling multiple devices to effectively share the same channel. This technology minimizes channel conflicts and enhances the overall transmission environment.
