4. Setup and Installation
Follow these steps for proper installation of your MPPT solar charge controller:
- Mounting: Choose a dry, well-ventilated location away from direct sunlight and heat sources. Ensure adequate space around the controller for air circulation.
- Battery Connection: Connect the battery cables to the controller's battery terminals (labeled '+' and '-'). Ensure correct polarity. The controller will automatically detect the battery voltage. Use 10 AWG wires for power terminals.
- Solar Panel Connection: Connect the solar panel cables to the controller's PV input terminals (labeled 'SOLAR +' and '-'). Ensure correct polarity. Verify that the open circuit voltage (Voc) and power of your solar array do not exceed the controller's maximum limits for your system voltage.
- Load Connection (Optional): Connect your DC load to the controller's load terminals (labeled 'LOAD +' and '-'). Ensure correct polarity.

5. Operating Instructions
Once connected, the controller will automatically begin operation. The LCD display provides real-time information:
- PV Input: Displays the voltage and current from the solar panels.
- Battery: Shows battery voltage, charge status, and percentage.
- Load Output: Indicates the voltage and current supplied to the load.
Control Buttons:
The controller features four buttons (A, B, C, D) and a SET button for navigation and parameter adjustment. Refer to the on-screen menu for specific functions. Pressing A+D for 5 seconds typically initiates a reset.
Cooling Fan Operation:
The integrated cooling fan activates automatically when the internal temperature exceeds 45°C and deactivates when the temperature drops below 40°C, ensuring optimal performance and longevity.
6. Battery Charging Methods
The OOYCYOO MPPT controller employs a 4-stage charging algorithm to optimize battery health and lifespan:
- Bulk Charge: Delivers maximum current to rapidly charge the battery.
- Boost Charge: Charges the battery to a higher voltage to ensure full charge.
- Float Charge: Maintains the battery at a safe voltage, compensating for self-discharge.
- Equalization: Periodically overcharges flooded lead-acid batteries to balance cell voltages.
Pre-set charging parameters are available for sealed, gel, flooded lead-acid, and LFP (lithium iron phosphate) batteries. Users can also customize charging parameters to suit other battery types or specific requirements.
