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.
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
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.

8. Troubleshooting
This section addresses common issues you might encounter with your solar charge controller.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on / LCD blank | No battery connected or battery voltage too low. Reverse polarity connection. | Ensure battery is connected first and has sufficient voltage. Check battery polarity. |
| No charging from solar panels | Solar panels not connected or reverse polarity. Insufficient sunlight. PV voltage too low or too high. | Check solar panel connections and polarity. Ensure adequate sunlight. Verify PV voltage is within operating range (e.g., 18V-96V for 12V system, 36V-96V for 24V system). |
| Load not working | Load output disabled. Load short circuit or overload. Battery voltage too low. | Check load output status on LCD. Disconnect load and check for short circuit. Ensure battery is sufficiently charged. |
| Controller overheating | Poor ventilation. Excessive load or charging current. | Ensure adequate airflow around the controller. Reduce load or charging current if possible. |
| Inaccurate voltage readings | Loose connections. Faulty temperature sensor. | Check all wiring connections. Ensure temperature sensor is properly connected. |
