2. Key Features

• 60A MPPT Charging Controller: Features a 4-stage battery charging algorithm (Bulk Charge, Boost Charge, Float Charge, and Equalization) for rapid, efficient, and safe charging.
• Wide Voltage/Power Support: Supports high PV input power and voltage. The controller can accept solar voltage up to 160V. Recommended solar power: 720W for 12V systems, 1440W for 24V, 2100W for 36V, and 2800W for 48V.
• Multi-Battery Compatibility: Compatible with various battery types including lead-acid (Sealed, Gel, Flooded) and Lithium (LFP) batteries. Charging parameters are pre-set and user-definable.
• High Tracking Efficiency: Advanced Maximum Power Point Tracking technology ensures continuous tracking of the array’s maximum power point, achieving tracking efficiency of not less than 98.1% and peak conversion efficiency up to 98%.
• Dual Cooling System: Constructed with die-cast aluminum for excellent heat dissipation. Includes a built-in cooling fan that activates when the temperature exceeds 45°C and turns off below 40°C, extending product life up to 5000 hours in normal use.
• Enhanced Safety Protections: Includes protection against PV overcurrent/power, PV short circuit, PV reverse polarity, night reverse charging, battery reverse polarity, battery over voltage, battery over discharge, battery overheating, controller overheating, lithium battery low temperature, load short circuit, load overload, and TVS high voltage transients.

3. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your solar charge controller. Always ensure all power sources are disconnected before making any connections.

3.1 Connection Order

1. Connect the Battery: First, connect the battery to the controller's battery terminals. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the battery voltage.
2. Connect the Solar Panels: Next, connect the solar panel array to the controller's PV terminals. Ensure correct polarity. The controller will begin charging the battery.
3. Connect the DC Load (Optional): Finally, connect your DC load to the load terminals. Do not exceed the maximum rated current for the load output.

Important: Always connect the battery first and disconnect the solar panels first when disassembling the system.

4. Operation

The controller features an LCD display and control buttons for monitoring and adjusting settings.

4.1 LCD Display and Buttons

The LCD display provides real-time information on system status, including battery voltage, charging current, and load status. Use the 'SET' button to enter settings mode and the 'A', 'B', 'C', 'D' buttons (or similar navigation buttons) to adjust parameters. A 5-second press on the 'SET' button typically initiates a reset or enters advanced settings.
