1. Carrier-Grade Dual SFP Fiber Ring Topology
The GL-Max3326 features two independent 1000Mbps SFP fiber ports integrating a heavy-duty 56G non-blocking backplane and 8K MAC table. This setup supports premium fiber ring network topologies spanning up to 120 kilometers. Even if one fiber segment suffers a physical break, the ring network instantly self-heals, making it the ultimate solution for long-range backbone data transmission in oil fields, highways, and border checkposts.
2. 24V/48V Smart Auto PoE with Manual DIP Control
No more field failures caused by voltage mismatches. Along with two high-draw 90W BT PoE ports for heavy cameras , it features two 30W Auto PoE ports controllable via an internal DIP switch. Technicians can instantly toggle between standard 48V PoE and 24V non-standard PoE , allowing the box to power standard IP cameras and proprietary 24V wireless bridges or telemetry modules simultaneously within a single chassis.
3. Embedded Hardware PoE & Fiber Watchdogs
Engineered for ultimate field reliability. The integrated hardware PoE Watchdog and Fiber Watchdog modules (enabled via internal DIP Switch lines 3 and 4) actively trace your communication paths. If a fiber connection stalls or an attached IP camera drops packets, the watchdog triggers a precise hardware reset on that exact channel—delivering autonomous healing without site-visit maintenance costs.
4. Real Online MPPT & Weak-Light Hybrid Discharge
Driven by a patented high-efficiency solar charge/discharge algorithm:
-
25% Power Amplification: Pure online MPPT tracks the optimal voltage/current trajectory of 300W solar panels.
-
Synchronous Weak-Light Discharge: Blends solar panel generation and battery resources simultaneously during cloudy weather, cutting down on battery depletion cycles and stretching its service life.
-
0V Battery Self-Activation: Features low-voltage EMD automatic activation to restore deeply discharged automotive-grade lithium cells back to full function.
5. Zero-Climb Ground Diagnostics & Smart Fan Regulation
-
0.96-inch Industrial OLED Display: Provides clean numbers for charge currents, panel voltages, active device loads, and cumulative solar yield.
-
8× F8 External Chassis LEDs: Allows line workers to trace battery level percentages, solar array operations, and hardware failures directly from the ground—completely avoiding the liabilities of climbing poles to crack open the cabinet.
-
40°C Active Thermal Regulation: Automatically controls fan speeds when internal metrics climb past 40℃ to lock down ideal thermal equilibrium.
Engineered for Customization & Secondary B2B Development
Crafted as an expandable industrial low-voltage platform for mission-critical edge installations, we offer extensive customization:
-
Interface Protocol Interoperability: Native RS485 ports running standard Modbus RTU telemetry alongside open IIC protocols for quick enterprise software script building.
-
Chassis & CNC Hole Customization: Custom CNC routing for dedicated cable inlets, mounting brackets, laser-etched private labels, and premium UV color logos applied on our aluminum alloy or stainless steel boxes.
-
Internal Expansion Architecture: Factory-reserved rack slots to install optical fiber terminal trays (4-port), 500W pure sine wave inverters ($24V input to AC 110V–240V output), or custom-heated battery jackets tailored for sub-zero fields down to -15℃.
Global Application Fields
The perfect independent solar-power infrastructure for long-distance, high-bandwidth data systems:
-
Forest Fire Prevention & National Parks: Supports 100KM+ optical fiber networks powering long-range heavy thermal pan-tilt-zoom cameras.
-
Highways, Transportation, & Cross-Border Security: Delivering local multi-voltage power for speed radars, IP cameras, and fiber optic relays along massive transit stretches.
-
Smart Water Conservancy & Hydrological Dams: Connecting radar water-level sensors, environmental telemetry, and long-range fiber links in remote locations.
