2. Installation and System Connection

Follow these steps for proper installation. Ensure all connections are secure and correct to prevent damage to the controller or other components. Always connect the battery first.

Figure 2: System Connection Diagram.

1. Connect Battery (1): Connect the battery to the charge controller first. Ensure correct polarity (+ to + and - to -). The controller will automatically detect 12V or 24V battery systems.
2. Connect Solar Panels (2): Connect the solar panel(s) to the charge controller. Again, observe correct polarity.
3. Connect DC Load (3 - Optional): Connect your DC loads (e.g., LED lights) to the controller's load terminals. Ensure correct polarity.
4. Connect Inverter (4 - Optional): If using an inverter for AC loads, connect it to the battery terminals. The inverter should not be connected directly to the load terminals of the controller.

Catetan penting: Connect in strict accordance with the sequence: 1. Battery, 2. Solar Panel, 3. Load. Disassembly should be in the reverse order to prevent damage.

Pamasangan:

• Mount the controller on a vertical surface to allow for proper heat dissipation.
• Ensure adequate clearance around the controller for air circulation.
• Avoid mounting in direct sunlight, high temperatures, or areas prone to water exposure.

3. Operasi jeung Setélan

The controller features an LCD display and three buttons for navigation and parameter adjustment.

3.1. LCD Témbongkeun Interface

Figure 3: LCD Display and Button Functions.

• Tombol MENU: Short press to switch between display interfaces. Long press (3-5 seconds) to enter or exit parameter setting mode.
• Tombol UP: In parameter setting mode, press once to increase the parameter value.
• DOWN/ON/OFF Button: In parameter setting mode, press once to decrease the parameter value. In normal display mode, press to turn the load on or off.

The LCD displays various information including voltage, ampere-hour, load output status, battery status, and solar panel charging light indicators (On: Direct/Boost Charge; Slowly Flash: Float Charge).

3.2. Parameter Setélan

To adjust parameters, long press the MENU button for 3-5 seconds to enter the setting interface. Use the UP jeung TURUN buttons to modify values. Long press the MENU button again to save and exit, or long press TURUN to restore default parameters.

The common adjustable parameters include:

• Ngapung Voltage: Voltage at which the battery is maintained after full charge.
• Discharge Reconnect Voltage: Voltage at which the load will reconnect after low voltage megatkeun sambungan.
• Discharge Stop Voltage: Voltage at which the load will be disconnected to protect the battery from over-discharge.
• Modeu Gawé: Configures how the load operates (e.g., 24 hours, dusk to dawn, timed).
• Jenis batré: Select the battery type (e.g., B01 for GEL, B02 for Sealed, B03 for Flood). This controller is only applicable to lead-acid batteries (Open type, VRLA, GEL, etc.).

5. Ngalereskeun Masalah sareng Perlindungan Kasalametan

The Thlevel solar charge controller is equipped with multiple safety features to protect itself and your solar power system. Understanding these protections can help in basic troubleshooting.

Figure 5: Built-in Security Protections.

• Perlindungan sirkuit pondok: Automatically disconnects if a short circuit is detected in the load or solar panel circuit. Check wiring for shorts.
• Perlindungan Overload: Disconnects the load if the current exceeds the rated capacity (20A). Reduce the load or use a higher-rated controller.
• Ngalangkungan Perlindungan Ayeuna: Similar to overload, protects against excessive current flow.
• Perlindungan panyebaran: Stops charging the battery once it reaches the set overcharge voltage, preventing damage.
• Dina-voltage panyalindungan: Disconnects the load when the battery voltage drops below the set under-voltage threshold, protecting the battery from deep discharge.
• Leuwih-voltage panyalindungan: Protects the system from excessively high voltage inputs.
• Perlindungan Polaritas Terbalik: Protects the controller from damage if the battery or solar panel connections are reversed. However, always ensure correct polarity during installation.

Masalah umum:

• Taya Témbongkeun / Taya Daya: Check battery connections and ensure the battery has sufficient charge.
• Batré Teu Ngecas: Verify solar panel connections, ensure panels are receiving sunlight, and check for any shading. Confirm battery type setting is correct.
• Beban Teu Gawé: Check load connections, ensure the load is within the controller's current limits, and verify the load work mode settings. The battery might be too low (under-voltagpanyalindungan e diaktipkeun).
