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. Vždy nejdříve připojte baterii.

Obrázek 2: Schéma zapojení systému.

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.

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

Montáž:

• 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. Obsluha a nastavení

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

Figure 3: LCD Display and Button Functions.

• Tlačítko MENU: Short press to switch between display interfaces. Long press (3-5 seconds) to enter or exit parameter setting mode.
• Tlačítko NAHORU: In parameter setting mode, press once to increase the parameter value.
• Tlačítko DOLŮ/ZAP/VYP: 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. Nastavení parametrů

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

Figure 4: Parameter Setting Flow.

The common adjustable parameters include:

• Float Voltage: Voltage at which the battery is maintained after full charge.
• Vybití Objem opětovného připojenítage: Voltage at which the load will reconnect after low voltage odpojení.
• Zastavení vypouštění Objemtage: Voltage at which the load will be disconnected to protect the battery from over-discharge.
• Pracovní režim: Configures how the load operates (e.g., 24 hours, dusk to dawn, timed).
• Typ baterie: 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.).

4. Údržba

Pravidelná údržba zajišťuje optimální výkon a dlouhou životnost vašeho solárního regulátoru nabíjení.

• Čistota: Udržujte ovladač čistý a bez prachu a nečistot. K čištění používejte suchý hadřík.
• Spojení: Periodically check all wiring connections to ensure they are tight and free from corrosion. Loose connections can cause overheating and damage.
• Větrání: Ujistěte se, že větrací otvory nejsou zablokované, aby bylo možné správné odvádění tepla.
• Podmínky prostředí: Verify that the controller is operating within its specified temperature and humidity ranges.
• Stav baterie: Sledujte stav a objem baterietage regularly. A healthy battery is crucial for the overall system performance.

5. Troubleshooting and Safety Protections

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.

• Ochrana proti zkratu: Automatically disconnects if a short circuit is detected in the load or solar panel circuit. Check wiring for shorts.
• Ochrana proti přetížení: Disconnects the load if the current exceeds the rated capacity (20A). Reduce the load or use a higher-rated controller.
• Nadproudová ochrana: Similar to overload, protects against excessive current flow.
• Ochrana proti přebití: Stops charging the battery once it reaches the set overcharge voltage., čímž se zabrání poškození.
• Pod voltage ochrana: Disconnects the load when the battery voltage klesne pod nastavený pod objemtage threshold, protecting the battery from deep discharge.
• Voltage ochrana: Protects the system from excessively high voltage vstupy.
• Ochrana proti přepólování: Protects the controller from damage if the battery or solar panel connections are reversed. However, always ensure correct polarity during installation.

Běžné problémy:

• Žádný displej/Žádné napájení: Check battery connections and ensure the battery has sufficient charge.
• Baterie se nenabíjí: Verify solar panel connections, ensure panels are receiving sunlight, and check for any shading. Confirm battery type setting is correct.
• Načtení nefunguje: 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-voltage protection activated).

7. Bezpečnostní informace

Please read and follow all safety instructions carefully before installation and operation.

• This controller is designed for 12V/24V lead-acid batteries only (GEL, Sealed, Flooded). Do not use with other battery types (e.g., Lithium-ion) unless explicitly stated by the manufacturer.
• Ensure all wiring is correctly polarized before connecting. Incorrect polarity can damage the controller and other components.
• Install the controller in a well-ventilated, dry, and cool environment, away from flammable materials and corrosive gases.
• Nepokoušejte se rozebírat ani opravovat ovladač sami. Servis svěřte kvalifikovanému personálu.
• Keep children away from the solar power system components.
• Během instalace používejte vhodné osobní ochranné prostředky (OOP), jako jsou rukavice a ochrana očí.
