GSP Series Industrial PWM PV Controller All-in-One Cabinet

• Thermal Design
Lateral Louver Ventilation: The left side panel is equipped with multiple sets of horizontal louvers, facilitating a natural lateral convection path for heat dissipation.
Vent-Free Front Panel: The front face is completely sealed to maintain a clean, streamlined appearance, concentrating all ventilation on the side panels.

• Human-Machine Interface (HMI)
Compact LCD Panel: Features a green backlit segment display for monitoring essential parameters—a cost-effective alternative to full-color touchscreens.
Physical Navigation Keys: Functional buttons are positioned directly below the screen, offering a straightforward and intuitive operational logic.
Streamlined Status Feedback: The unit omits external LED status lights, consolidating all operational data and system alerts directly onto the digital display.

• Security & Locking
Single-Point Long-Handle Lock: A high-quality industrial lock on the right side controls access to the entire cabinet, ensuring secure operation and convenient maintenance.

• Charging Technology
PWM Charging Integration: Utilizes Pulse Width Modulation (PWM) technology. This cost-optimized charging solution is ideally suited for applications where high-efficiency MPPT tracking is not a critical requirement.

Installation & Compatibility
Installation Method: Mobile floor-mounted installation; bottom rollers facilitate positioning, then locked with brakes; no anchor bolt holes; relies on roller locking to maintain position.
System Compatibility: PWM charging technology compatible with lead-acid batteries and basic lithium batteries; lower cost than MPPT solutions; PV input and battery output terminals located at rear or inside cabinet.
Easy Maintenance: Upper independent small door opens to view operating status; side louvers can be cleaned externally; roller design facilitates pulling out for maintenance.

Applications
Off-Grid Residential Systems: Home PV power supply in remote areas; PWM technology meets basic charging needs at controlled cost.
Rural PV Poverty Alleviation: Village-level PV stations or household rooftop projects; economical controllers reduce overall investment.
Traffic Signal Power Supply: Independent PV power systems for road monitoring, traffic signals, and street lights.
Small Irrigation Systems: Paired charge control for agricultural PV water pumps to meet seasonal water demand.
