5. Setup and Installation
Follow these steps for a quick and correct installation of your solar charge controller. The controller automatically detects 12V or 24V system voltage.
Figure 5.1: 3-Step Connection Process.
- Connect to Battery: Connect the battery to the controller's battery terminals (9). Ensure correct polarity (+ to + and - to -). This step must be done first.
- Connect to PV (Solar Panel): Connect the solar panel to the controller's PV terminals (10). Ensure correct polarity.
- Connect to Loads: Connect your DC loads to the controller's load terminals (8). Ensure correct polarity.
Important Considerations:
- Mount the controller vertically on a wall or flat surface to ensure proper heat dissipation.
- Use appropriate wire gauges for all connections to minimize voltage drop and ensure safety.
- Connect the included temperature sensor (11) to the battery for accurate temperature compensation during charging.

6. Operating Instructions
6.1. LCD Display
The high-resolution LCD screen (4) provides real-time information about the system's status and any error messages.
Figure 6.1: LCD Display Information.
- Operating Status: Indicates current charging mode (Bulk, Absorb, Float, Full) and system activity.
- Fault Information: Displays error codes or warnings if any issues are detected.
- Voltage Data: Shows PV (solar panel) voltage, battery voltage, and load voltage.
- Battery Type: Indicates the currently selected battery type (GEL, SLA, FLD, LFP, CUS).
- Other Data: Includes Day/Total energy, current (A), and kilowatt-hours (KWh).
6.2. Button Functions
- Setting/Load Switch (1): Press to cycle through display screens or enter settings mode.
- Up (2) / Down (3): Navigate through menu options or adjust parameter values in settings mode.
- Confirm (5): Confirm selections or save settings.
6.3. Battery Type Selection
The controller is compatible with various battery types. It is crucial to select the correct battery type for optimal charging and battery longevity.
Figure 6.2: Multi-voltage and Multi-battery Compatibility.
To change the battery type:
- Press the Setting/Load Switch button (1) until the battery type setting is displayed.
- Use the Up (2) or Down (3) buttons to select your battery type: GEL, SLA (Sealed Lead Acid), FLD (Flooded), LFP (Lithium Iron Phosphate), or CUS (User-defined).
- Press the Confirm button (5) to save your selection.
6.4. Smart 3-Stage Charging
The controller employs a 3-stage charging algorithm to extend battery life and optimize performance:
Figure 6.3: Battery Health Features.
- Bulk Charge: Charges the battery at maximum current until voltage rises to the absorption level.
- Uniform Charge (Equalization): Applies a controlled overcharge to flooded batteries to balance cell voltage and remove sulfation. (Not applicable to GEL/SLA/LFP).
- Float Charge: Maintains the battery at a full state of charge by providing a very low current.
6.5. Bluetooth Monitoring
The integrated Bluetooth module allows for remote monitoring and control via a smartphone application.
Figure 6.4: Bluetooth Control and Monitoring.
- Download the ECO-WORTHY monitoring application from your smartphone's app store.
- Ensure the Bluetooth module is connected to the controller's RS485 interface (7).
- Open the app and search for available devices. Connect to your controller.
- You can now monitor battery status, charging parameters, and adjust settings remotely within a 10-40 meter range.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your solar charge controller.
- Cleaning: Periodically clean the controller's exterior with a dry cloth to remove dust and debris. Ensure ventilation openings are clear.
- Connection Checks: Annually inspect all wiring connections for tightness and corrosion. Re-tighten if necessary.
- Performance Monitoring: Regularly check the LCD display or use the Bluetooth app to monitor system performance. Note any unusual readings or error messages.
- Battery Inspection: Inspect batteries for any signs of damage, leakage, or corrosion. Ensure battery terminals are clean.
8. Troubleshooting
This section addresses common issues you might encounter with your solar charge controller.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller display is off | No power from battery or solar panel; incorrect wiring. | Check battery and solar panel connections and polarity. Ensure battery voltage is above minimum operating voltage. |
| Battery not charging | Solar panel not connected; insufficient sunlight; faulty solar panel; incorrect battery type setting. | Verify solar panel connection. Check solar panel output voltage. Ensure adequate sunlight. Confirm correct battery type is selected. |
| Load not working | Load disconnected; overload; short circuit; low battery voltage. | Check load connections. Reduce load if overloaded. Inspect for short circuits. Allow battery to charge. |
| Error code displayed | Specific system fault (e.g., over-voltage, over-current, high temperature). | Refer to the detailed error code list in the full user manual (if provided) or contact customer support with the specific code. |
