The controller features a clear LCD display on the front for monitoring system status. Below the display are control buttons for navigation and settings. Connection terminals for solar panels, battery, and load are located at the bottom. USB ports and an RS485 communication port are on the side.

4. Setup and Installation

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

4.1 Mounting the Controller

Choose a dry, well-ventilated location, protected from direct sunlight, high temperatures, and water.
Ensure there is sufficient space around the controller for heat dissipation.
Mount the controller vertically on a wall or stable surface using the provided mounting holes.

4.2 Wiring Connections

Follow the connection order precisely to avoid damage to the controller or other components.

Connect the Battery: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the controller. Ensure correct polarity. The controller will automatically detect the system voltage (12V or 24V).
Connect the Solar Panels: Connect the positive and negative leads from your solar panel array to the corresponding PV terminals on the controller. Ensure correct polarity. Do not exceed the maximum PV input voltage of 100V DC.
Connect the Load (Optional): Connect your DC loads to the load terminals on the controller. Note that the load output is for DC loads only. Do not connect inverters or inductive loads directly to these terminals.
Connect the Remote Temperature Sensor: Plug the temperature sensor into its dedicated port. This sensor helps the controller optimize charging based on battery temperature.

The diagram also shows optional AC load connection via an inverter (not directly to the controller's load terminals).

Important Note: Always connect the battery first and disconnect the solar panel last. Incorrect connection order can damage the controller.

5. Operating Instructions

Once installed, the controller will begin operation automatically. The LCD display provides real-time system information.

5.1 LCD Display and Buttons

OOYCYOO MPPT 60A Solar Charge Controller LCD display — Figure 3: Close-up of the controller's backlit LCD display showing various parameters like PV voltage, battery voltage, load current, and charging status. Below the screen are four control buttons.

The backlit LCD displays critical system parameters such as PV voltage, battery voltage, charging current, load current, and accumulated energy (KWH). The four buttons below the display are used for navigation and settings adjustment:

Toggle Key: Used to cycle through display screens or confirm selections.
'+' (Plus) Key: Increases values or moves forward in menus.
'-' (Minus) Key: Decreases values or moves backward in menus.
Manual Switch Load Key: Toggles the load output on/off manually.
5S Reset: Press and hold for 5 seconds to restore factory settings.

5.2 Battery Charging Algorithm

The controller utilizes a 4-stage charging algorithm to optimize battery life and performance:

Bulk Charge: Charges the battery at maximum current until the voltage reaches the boost voltage.
Boost Charge: Charges at a constant voltage for a set period to ensure full charge.
Float Charge: Maintains the battery at a lower voltage to prevent self-discharge and overcharging.
Equalization (for specific battery types): Periodically overcharges the battery to balance cell voltages and prevent sulfation.

5.3 Supported Battery Types

The controller is compatible with various battery types, including:

Lead-Acid (Sealed, Gel, Flooded)
Lithium (LFP)
User-defined parameters for other battery types.

Pre-set charging parameters are available for Sealed, Gel, Flooded, and LI (LFP) batteries. Users can customize parameters for other battery types as needed.
