• Dual Cooling, Efficient Heat Dissipation: Constructed with die-cast aluminum for excellent heat dissipation and reduced power consumption. Features an upgraded turbofan fan for efficient and quiet cooling, activating at temperatures above 45°C and turning off below 40°C. Suitable for RVs, commercial vehicles, boats, yachts, and various solar systems.
• Compatible with Multiple Battery Types: Negative grounding design for enhanced safety. Compatible with 12V/24V/36V/48V lead-acid (Sealed, Gel, Flooded) and lithium (LiFePO4 and Lithium-Ion) batteries. Pre-set charging parameters are available, with user customization options for Absorption Voltage, Float Voltage, Low Voltage Cutoff, and Load Timer.
• Wide Range Voltage/Power Support: Supports high PV input power and voltage. The controller can accept solar voltage up to 160V. Recommended solar power for 12V systems is 1200W (PV input DC20V~DC80V); 2400W for 24V (37~105V); 3600W for 36V (50~160V); and 4800W for 48V (72-160V).
• Enhanced Protection and Lithium Battery Compatibility: Provides comprehensive protection against overcurrent, short circuit, reversed polarity, overvoltage, over-discharge, and over-temperature. Features an external temperature probe for precise battery temperature monitoring. Activates lithium batteries with solar panel energy (with precautions against overcharging). Note: Do not charge lithium batteries when the temperature is below 0°C.
• 99% Tracking Technology: Utilizes advanced Maximum Power Point Tracking (MPPT) technology to continuously track the array’s maximum power point, ensuring maximum power delivery to charge the battery. Tracking efficiency is not less than 99%, with a peak conversion efficiency of up to 97%.

3. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your solar charge controller. Follow these steps carefully.

3.1 Mounting the Controller

Mount the controller vertically on a sturdy, non-flammable surface, ensuring adequate ventilation around the unit for heat dissipation. Keep it away from direct sunlight, high temperatures, and moisture.

3.2 Wiring Connections

Always connect the battery first, then the solar panels. Ensure all circuit breakers are open before making any connections. Use appropriate wire gauges for your system's current and distance.

1. Battery Connection: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the controller. Ensure a secure connection.
2. Solar Panel Connection: Connect the positive and negative leads from your solar array to the PV input terminals on the controller.
3. Load Connection (Optional): If using the load output, connect your DC load to the load terminals.

4.2 Setting Battery Type and Parallel Code

To optimize charging, select the correct battery type via the controller's settings. When using multiple controllers in parallel, ensure the parallel communication code is correctly set on each unit. The device with the smallest code becomes the main controller, and others synchronize their settings automatically.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your solar charge controller.

5.1 General Care

• Keep the controller clean and free from dust and debris.
• Ensure all connections are tight and secure. Periodically check for any loose wiring.
• Verify that the cooling fan is not obstructed and operates correctly when temperatures rise.

6. Troubleshooting

If you encounter issues with your controller, refer to the following common problems and solutions. The controller's built-in protections are designed to prevent damage from various faults.

• No Display/Power: Check battery connections and ensure the battery circuit breaker is closed. Verify battery voltage is within the operating range.
• No Charging: Ensure solar panels are connected correctly and receiving sufficient sunlight. Check PV input voltage on the display. Verify solar circuit breaker is closed.
• Over-temperature Warning: Ensure adequate ventilation around the controller. Check if the cooling fan is operating. Reduce load or solar input if necessary.
• Battery Not Fully Charged: Verify battery type settings are correct. Check charging parameters (Absorption/Float Voltage). Ensure solar array size is sufficient for your battery bank.
• Error Codes: Refer to the specific error code displayed on the LCD for detailed information and troubleshooting steps.
