Hybrid Charging Technology Explained

This controller features an innovative MPPT+PWM hybrid charging algorithm, combining MPPT dynamic tracking with optimized PWM functionality to intelligently adapt to varying sunlight conditions: ·Sunlight Optimization Mode: Automatically activates MPPT tracking under strong sunlight, achieving up to 93% power conversion efficiency to maximize solar energy harvest.

·Low-Light Adaptation: Switches to refined PWM mode during cloudy or weak-light conditions, minimizing circuit losses while ensuring stable charging currents.

Why Choose Hybrid Technology?

1·Weather Resilience: Responds faster than pure MPPT controllers in rapidly changing weather (e.g., passing clouds), reducing energy loss caused by tracking delays.

2·Cost-Effective Performance: Delivers 85%+ MPPT efficiency at a fraction of the cost, while retaining PWM’s circuit protection stability.

3·Battery Longevity: Dual-algorithm synergy prevents overcharging and extends service life for lead-acid/lithium batteries.

Core advantages of this solar controller:

·Real-time photovoltaic monitoring: High-definition LCD screen dynamically displays solar panel voltage, accurately locates faults, and improves power generation efficiency by 10%-15%;

·Second-level timing accuracy: load mode timing error is only ±1-2 seconds (traditional ±30 seconds), suitable for high-efficiency scenarios such as irrigation and security;

· Smart Active-Passive Cooling

       8mm aviation aluminum fins (passive cooling) + Intelligent fan (active cooling:120A/150A). Auto Fan Logic: Activates at >45°C or >80A sustained current (quiet low-speed mode). Shuts down at <40°C and <30A current (zero noise, energy-saving). Performance: (120A/150A)Full-load temperature ≤65°C in 40°C ambient, 20°C cooler than competitors.

· Triple Safety Integration Over-voltage/current protection + Fan failsafe (forced cooling at >75°C to prevent shutdown).

Note: The smart fan is an exclusive upgrade for 120A/150A models. It solves the heat dissipation bottleneck of high-power systems through the intelligent temperature control-current dual trigger mechanism, while taking into account quietness and energy consumption. Low-power models (≤100A) still meet the needs through heat sink design.

Note for Users: This product is not a full-time MPPT controller. For large off-grid systems requiring 100% continuous MPPT tracking, we recommend professional-grade MPPT models. For small-to-medium residential/outdoor setups, this controller has passed 72-hour extreme-environment testing, delivering 92% energy efficiency compared to industry peers in its class.

Features & Operation Guide

1】7 Working Modes

-Light Control: Auto-start discharge at night, delay 10 minutes at sunrise.

-Timer Control: Custom discharge schedule (e.g., 6 PM–6 AM).

-Light+Timer Mode: Combines light sensing and timing for energy savings.

-Manual Mode: One-click load control for emergencies.

-Charge-Only Mode: Prioritizes battery charging with no discharge.

-Universal Mode: Continuous discharge (ideal for stable power needs).

-Test mode: it is the same as light and time delay control mode but only loses ten minutes of time delay "▲" value and mode adjustment button; "■" set/confirm button; "▼" shift and forced start/stop button.

2】Installation Steps

·Wiring Order: Battery → Solar Panel → Load (Inverters must connect directly to the battery).

·Mode Setup:

1.Press ■ to enter menu, use ▲ to toggle modes.

2.Hold ■ to confirm; LCD displays active mode.

 3】Troubleshooting

  ·Fault Indicator: Check battery voltage, current, or temperature if icon flashes.

  ·Reset: Hold ▼ for 5 seconds to restore defaults.

Important Notes

1-Installation:

·Ensure total solar panel voltage ≤100V to avoid triggering protection.

·Avoid exposing the controller to extreme temperatures (operating range: -25°C~55°C).

2-Compatibility: ·Use high-voltage inverters for 48V systems to maximize efficiency.
