2. Installazione e configurazione

2.1 Montaggio

Mount the controller in a well-ventilated area, away from direct sunlight, high temperatures, and water. Ensure there is sufficient airflow around the heat sink fins (see Figure 3) for proper cooling. The controller should be mounted vertically on a wall or stable surface.

2.2 Istruzioni per il cablaggio

Follow these steps for safe and correct wiring:

1. Preparare il controller: Open the terminal cover and loosen the screw terminals.
2. Collegare la batteria: Connect the battery to the controller's battery terminals first. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the 12V or 24V system voltage.
3. Collegare il pannello solare: Collegare il pannello solare ai terminali FV del controller. Assicurarsi della corretta polarità.
4. Collegare il carico (facoltativo): Se si utilizza un carico CC direttamente dal controller, collegarlo ai terminali del carico.

Important: Always connect the battery first, then the solar panel. Disconnect in reverse order (solar panel first, then battery).

3. Funzionamento

3.1 LCD Display and Parameter Setting

The controller features an LCD screen that dynamically displays operating data and working status. Use the 'MENU' and 'SET' buttons to navigate and adjust parameters.

Common display interfaces include:

• Interfaccia principale: Mostra il volume della batteriatage e lo stato di carica.
• Volume di sistematage Selezionare: Allows selection of system voltage (though auto-detection is primary).
• Potenza di carica totale: Displays accumulated charge power.
• Modalità di caricamento: Shows current load control mode.
• Carica Disconnetti voltage: Volume configurabiletage at which load is disconnected.
• Volume galleggiantetage: Configurable float charge voltage.
• Carica Riconnetti voltage: Volume configurabiletage at which load is reconnected.

3.2 Selezione del tipo di batteria

The controller supports 5 battery modes. Select the appropriate battery type for optimal charging and protection. When battery voltage raggiunge un volume elevatotage disconnection point, the controller will automatically switch to PWM charging for safety.

Supported battery types include:

• Auto 12V/24V Lead-Acid
• 12V piombo-acido
• 24V piombo-acido
• Batteria LiFePO12 da 4 V
• Batteria LiFePO24 da 4 V
• Ternary Lithium (Li(NiCoMn)O2)

3.3 Modalità di lavoro del carico

The controller offers various load control modes to suit different applications:

• Modalità manuale (24 ore): The load is continuously on for 24 hours.
• Modalità di controllo della luce solare (tramonto-alba): Il carico si accende al tramonto e si spegne all'alba.
• Luce solare + controllo del tempo: The load turns on at sunset and stays on for a set duration, then turns off.
• Modalità di ricarica pura: The controller only charges the battery, the load output is always off.
• Modalità di cronometraggio: The load operates according to a user-defined schedule.

3.4 porte di ricarica USB

The controller is equipped with dual USB ports, allowing you to charge compatible devices directly from the controller. Refer to Figure 8 for port location.

4. Manutenzione

To ensure the longevity and optimal performance of your PowMr solar charge controller, regular maintenance is recommended:

• Mantenere pulito: Periodically clean the controller's exterior, especially the heat sink fins, to prevent dust buildup that can hinder cooling.
• Controllare le connessioni: Annually inspect all wiring connections to ensure they are tight and free from corrosion. Loose connections can cause overheating and poor performance.
• Visualizzazione del monitor: Controllare regolarmente il display LCD per individuare eventuali codici di errore o letture insolite.
• Ispezione della batteria: For lead-acid batteries, check electrolyte levels and terminal cleanliness as per battery manufacturer guidelines.

5. Risoluzione Dei Problemi

The controller is equipped with fault diagnosis technology to indicate system errors. If you encounter issues, check the following:

• Nessun display/Nessuna alimentazione:
  • Check battery connections and ensure the battery is charged above the minimum operating voltage.
  • Verify that the battery polarity is correct.
• Nessuna ricarica:
  • Assicurarsi che i pannelli solari siano collegati correttamente e ricevano la luce solare.
  • Check solar panel polarity.
  • Verify that the battery type setting matches your battery.
• Carico non funzionante:
  • Check load connections and ensure the load is not exceeding the controller's rated current.
  • Verify the selected load working mode (e.g., if it's in 'Pure Charging Mode', the load will be off).
  • Controllare il volume della batteriatage; if it's below the load disconnect voltage, the load will be off.
• Codici di errore: If an error code appears on the LCD, refer to the full product manual (if available) or contact customer support for specific interpretations.

6. Specifiche

7. Suggerimenti per l'utente

• Always double-check wiring polarity before connecting to prevent damage to the controller or batteries.
• Ensure your solar panel's open-circuit voltage (Voc) non supera il volume massimo di ingresso del controllertage.
• For optimal performance, place the controller in a cool, dry, and well-ventilated location.
• Regularly monitor the LCD display to understand your system's performance and identify any potential issues early.
