4. Installation and Wiring

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 away from direct sunlight and heat sources.
Mount the controller vertically on a non-flammable surface to allow for optimal heat dissipation.
Use the provided mounting hardware and preserved mounting holes or side mounting plates to secure the controller.
Ensure there is sufficient clearance around the controller for air circulation.

4.2 Wiring Sequence

Connect the components in the following order to prevent damage to the controller or battery:

Connect the Battery: Connect the battery to the controller's battery terminals. Ensure correct polarity (positive to positive, negative to negative). The controller will auto-detect the system voltage (12V or 24V).
Connect the Solar Panels (PV Array): Connect the solar panel array to the controller's PV input terminals. Ensure correct polarity. Do not exceed the maximum PV input voltage of 150V.
Connect the DC Load (Optional): Connect your DC loads to the controller's load output terminals. Ensure correct polarity.

Important: Always connect the battery first, then the solar panels, and finally the load. Disconnect in the reverse order: load, then solar panels, then battery.

**Figure 4.1:** Easy Connection Diagram. This diagram illustrates the correct wiring sequence for connecting the solar panel, battery, and load to the MPPT solar charge controller using thick and tight terminals.

4.3 Connecting the Temperature Sensor

Connect the included temperature sense cable to the designated port on the controller. This allows the controller to monitor battery temperature and adjust charging parameters for optimal battery health and lifespan.

5. Operation

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

5.1 System Voltage Auto-Detection

The NS24H60 automatically detects 12V or 24V battery systems upon initial connection. Ensure your battery bank voltage matches the system voltage.

5.2 Battery Type Selection and Activation

The controller is compatible with various battery types. You can select the appropriate battery type through the controller's interface to ensure optimal charging. Supported types include LiFePO4, Lithium, AGM, Gel, Flooded, Sealed Lead-Acid, and user-defined battery types.

The built-in Lithium Activation function can help recover lithium batteries that have entered a low-voltage shutdown state due to their Battery Management System (BMS), restoring their charging capability without requiring an external charger.

5.3 Charging Modes

The controller employs a multi-stage charging algorithm to optimize battery health and lifespan:

Bulk Charge: Charges the battery at maximum current until voltage reaches the absorption level.
Constant Charging (Absorption): Maintains a constant voltage while current gradually decreases.
Float Charge: Reduces voltage to a lower level to maintain the battery at full charge.
Equalization Charge (for Lead-Acid): Periodically overcharges the battery to balance cell voltages and prevent sulfation.
