Off-Grid LoRaWAN Gateway for Remote IoT: SG50 Solar 4G Gateway for Farms and Industrial Sites
Deploying a LoRaWAN network in a city, factory or office is relatively straightforward when fixed electricity and wired internet are available. The situation becomes more difficult when sensors and tracking devices must operate on remote farms, open pastures, construction sites, water infrastructure, forests or isolated industrial facilities.
An off-grid LoRaWAN gateway is designed for these locations. It combines long-range LoRaWAN communication with solar or DC power, backup batteries and 4G LTE cellular connectivity. The gateway can collect information from multiple LoRaWAN devices and forward it to a network server without depending on local grid power or fixed broadband.
The SG50 Solar LoRaWAN Gateway is an outdoor, eight-channel IoT gateway developed for remote installations. It supports solar power, 4G LTE, integrated backup batteries, global LoRaWAN frequency options and an IP67 metal enclosure.
Jinshengchang supplies the SG50 Solar LoRaWAN Gateway for smart farming, livestock tracking, environmental monitoring, remote utilities and industrial IoT projects.
What Is an Off-Grid LoRaWAN Gateway?
An off-grid LoRaWAN gateway is a communication device that can operate without a conventional electrical grid or fixed internet connection.
The system normally uses:
Solar power or another independent DC source
Rechargeable backup batteries
LoRaWAN communication
4G LTE cellular backhaul
Outdoor antennas
A weather-resistant enclosure
Wall or pole mounting
LoRaWAN devices transmit sensor, location or alarm data to the gateway. The gateway then sends the information to a LoRaWAN network server through the mobile network.
This architecture is suitable for remote areas where installing electricity and broadband would be difficult or expensive.

Solar Power and Backup Battery System
The SG50 can receive solar or DC power through an M12 connector. It also supports 3.6V, 25,000mAh backup batteries.
According to the product configuration, the batteries can support up to approximately four days of operation without sunlight under a reference load of 100 connected nodes reporting every ten minutes.
Actual backup time depends on:
Number of connected devices
Reporting frequency
Cellular signal quality
LoRaWAN traffic
Downlink activity
Temperature
Battery condition
Network retries
Gateway configuration
The stated battery life should therefore be treated as a reference condition rather than a fixed result for every project.
A remote installation should calculate:
Daily gateway power consumption
Solar-panel output
Battery capacity
Average sunlight hours
Seasonal weather
Required backup days
Charging temperature
Cable losses
Panel orientation
A solar panel that works during summer may not provide sufficient power during winter, prolonged rain or cloudy weather. The solar and battery system should be sized according to the actual installation region.
IP67 Outdoor Protection
The SG50 uses an IP67-rated cast-aluminum enclosure.
This protection makes it suitable for outdoor locations exposed to:
Rain
Dust
Wind
Agricultural environments
Remote infrastructure
Industrial sites
Seasonal weather changes
The gateway supports wall or pole mounting, allowing the installer to position it above major obstacles.
IP67 protection does not eliminate the need for correct installation. Cables, connectors, antennas and mounting accessories must also be protected against water ingress, corrosion and mechanical damage.
For exposed sites, the project should also evaluate:
Lightning protection
Surge protection
Grounding
Pole strength
Wind resistance
Antenna sealing
Cable routing
Protection against unauthorized removal
Eight-Channel LoRaWAN Communication
The SG50 provides eight half-duplex LoRaWAN channels.
An eight-channel gateway can receive packets from multiple devices operating with supported frequencies and spreading factors. It can be used with:
Livestock GPS collars
LoRaWAN ear tags
Personnel safety badges
Asset trackers
Temperature sensors
Soil-moisture sensors
Water-level sensors
Weather stations
Smart meters
Irrigation controllers
SOS buttons
Industrial monitoring terminals
When connected to an external LoRaWAN network server, the SG50 is listed as supporting approximately 2,000 Class A, Class B and Class C devices.
The real network capacity depends on:
Device-reporting interval
Packet size
Spreading factor
Confirmed or unconfirmed messages
Downlink frequency
Radio interference
Number of simultaneous transmissions
Packet retransmissions
Signal quality
A network with 2,000 sensors transmitting once per hour has very different requirements from 2,000 GPS trackers uploading every minute.
Gateway quantity should be calculated according to device traffic, not only the total number of devices.
Embedded LoRaWAN Network Server
The SG50 includes an embedded network server compatible with LoRaWAN V1.0.3 Class A and Class C devices.
The embedded server can support up to approximately 100 devices. This function is useful for:
Pilot projects
Small private LoRaWAN networks
Demonstration systems
Independent farms
Remote monitoring stations
Proof-of-concept deployments
For larger projects, the gateway can forward data to an external network server.
The two operating modes should not be confused:
Around 2,000 devices may be supported when the gateway forwards packets to a suitable external server under appropriate traffic conditions.
The built-in network server supports a smaller deployment of up to approximately 100 devices.
ChirpStack and Network-Server Compatibility
The SG50 supports common packet-forwarding and network-server options:
Semtech UDP Packet Forwarder
LoRa Basics Station TCP Forwarder
ChirpStack V3
ChirpStack V4
Milesight Embedded Network Server
DeviceHub LNS
Milesight Development Platform LNS
It also supports MQTT integration.
For a private ChirpStack project, the installer may need to configure:
Gateway ID
Server address
Communication ports
Frequency plan
Packet-forwarding protocol
Authentication
Certificates
Device profiles
Application integration
Jinshengchang can help customers connect the gateway to the lora8 platform or evaluate integration with a customer-hosted server.
4G LTE Backhaul
The SG50 includes 4G LTE CAT 1 and GSM communication with a Nano SIM slot.
Versions are available for international and North American cellular bands.
The global version supports multiple LTE-FDD and LTE-TDD bands. The North American version provides bands intended for operators in that region.
4G communication makes the gateway suitable for locations without Ethernet, including:
Remote livestock farms
Open pastures
Forest areas
Construction sites
Water-pumping stations
Utility infrastructure
Solar farms
Mines
Environmental monitoring stations
Before purchasing, customers should confirm:
Deployment country
Mobile operator
Available cellular bands
SIM-card requirements
Data plan
Signal strength at the site
APN configuration
Private or public IP requirements
A 4G version with incompatible cellular bands may not connect to the local network.
Global LoRaWAN Frequency Support
The SG50 supports multiple regional LoRaWAN frequency plans:
CN470
IN865
EU868
RU864
US915
AU915
KR920
AS923-1
AS923-2
AS923-3
AS923-4
The gateway and LoRaWAN end devices must use compatible regional frequencies.
For example:
EU868 is used in many European projects.
US915 is intended for the United States.
AU915 is used in Australia and certain other markets.
IN865 is designed for India.
KR920 is used in South Korea.
AS923 variants are used in several Asian countries.
The operating country must be confirmed before the gateway and end devices are ordered.
LoRaWAN Gateway for Livestock Tracking
Large ranches are a strong application for an off-grid LoRaWAN gateway.
A livestock tracking network can include:
GPS cattle collars
Sheep tracking collars
LoRaWAN ear tags
Water-level sensors
Pasture weather sensors
Virtual-fence alerts
Gate-status sensors
Equipment trackers
Jinshengchang’s LoRa GPS livestock tracking collar can transmit position, battery and geofence information through a LoRaWAN network.
The SG50 receives the collar data and sends it to the platform through 4G.
Compared with installing a cellular SIM card in every collar, a LoRaWAN architecture can reduce recurring communication costs when many animals remain within gateway coverage.
However, coverage depends on:
Pasture dimensions
Hills and valleys
Trees
Buildings
Gateway height
Antenna position
Collar-reporting interval
Radio interference
One gateway cannot automatically cover every ranch. Large or complex pastures may require several installation points.
Remote Asset Tracking
The SG50 can also support remote asset-monitoring networks.
Compatible devices may track:
Agricultural machinery
Trailers
Water pumps
Generators
Construction equipment
Containers
Mobile tools
Remote infrastructure
A LoRa industrial asset tracker can transmit location, movement and equipment-status information to the gateway.
This architecture is useful when many assets operate within a farm, construction site, industrial park or mining area.
Personnel Safety at Remote Sites
Remote industrial sites may need worker-safety functions as well as equipment monitoring.
A LoRaWAN personnel system can support:
Employee identification
SOS alarms
Lone-worker protection
Man-down alerts
Zone-entry records
Battery notifications
Movement information
The LoRa employee tracking badge with SOS can communicate with a LoRaWAN gateway as part of a personnel-safety solution.
For critical worker-safety applications, the complete system should include:
Gateway-coverage testing
Backup power
Server monitoring
Communication-loss alarms
Defined emergency procedures
Regular system tests
The gateway is one component of the safety system and should not be treated as the complete emergency solution by itself.
SG50 Applications Beyond Farming
Although the SG50 is well suited to smart agriculture, it can also be used in other remote IoT applications.
Water infrastructure
The gateway can collect information from:
Water-level sensors
Flow meters
Pressure sensors
Pump controllers
Smart valves
Leakage sensors
Environmental monitoring
Possible devices include:
Weather stations
Rain gauges
Air-quality sensors
Soil sensors
River-level monitors
Forest-fire detection sensors
Solar and energy sites
The network can connect:
Equipment-status sensors
Temperature sensors
Security alarms
Energy meters
Cabinet-door sensors
Maintenance terminals
Construction and mining
Applications can include:
Equipment tracking
Personnel safety
Fuel monitoring
Water-level monitoring
Geofence alarms
Environmental sensors
GPS Function in the Gateway
The SG50 includes GPS functionality and shares an external antenna with the cellular interface.
GPS can help identify or manage the gateway installation position. It does not replace GPS tracking devices attached to animals, workers or assets.
The gateway’s GPS position represents the location of the gateway itself. End-device locations must still be obtained from GPS-enabled collars, trackers or other positioning terminals.
Low-Power Operation
The SG50 has a typical listed power consumption of approximately 0.8W.
Low power consumption is important for solar deployment because it reduces the required solar-panel and battery capacity.
Actual power use can vary with:
4G signal strength
Data traffic
Wi-Fi activity
Connected-device quantity
Operating temperature
Cellular retries
Management functions
Battery charging
Power-system planning should use measured project conditions whenever possible.
Remote Configuration and Management
The SG50 provides management functions including:
HTTP and HTTPS
MQTT
OpenVPN client
Web configuration
MQTT API
DeviceHub
Milesight Development Platform
Remote updates
Ping diagnostics
Watchdog
Timer
Packet filtering
Data retransmission
Remote management is especially important because off-grid gateways may be installed far from technical staff.
Before deployment, the project should define:
Remote access method
Administrator permissions
Password policy
VPN configuration
Firmware-update procedure
Failure notifications
Maintenance schedule
SIM-card monitoring
How to Plan an SG50 Deployment
A remote gateway project should begin with a site assessment.
Confirm the installation country
This determines the LoRaWAN and cellular frequency versions.
Measure the cellular signal
A solar gateway cannot upload data if the 4G signal is too weak or unstable.
Map the LoRaWAN devices
Identify device locations, terrain, buildings and major radio obstacles.
Calculate network traffic
Record the number of devices, packet size and reporting interval.
Design the solar system
Calculate daily consumption, sunlight availability, battery capacity and backup time.
Select the mounting position
A higher installation position often improves LoRaWAN coverage, but it must also provide safe maintenance access.
Test before mass deployment
Use sample devices to test communication at critical locations before purchasing the final quantity.
Factors Affecting SG50 Price
The SG50 Solar LoRaWAN Gateway price depends on the project configuration.
