2. Informazioni sulla sicurezza

Please read all instructions carefully before installation and operation. Failure to follow these instructions may result in damage to the unit, battery, or other components, and may cause personal injury.

• Ensure all connections are tight and correct to prevent excessive voltage drop and potential overheating.
• Collegare sempre prima la batteria al controller, poi al pannello solare e infine al carico. Scollegare seguendo l'ordine inverso.
• Do not attempt to repair or modify the controller. Refer to qualified personnel for service.
• Installare il controller in un'area ben ventilata, lontano da materiali infiammabili e dalla luce solare diretta.
• The controller is rated IP32, meaning it is protected from tools and wires greater than 2.5 millimeters and from spraying water. It is not waterproof and should not be exposed to heavy rain or submerged.

4. Specifiche

5. Impostazione

Follow these steps for proper installation of your solar charge controller. Incorrect wiring can damage the controller and other components.

5.1. Metodo di connessione

1. Collegare la batteria: Connect the battery to the controller's battery terminals (marked with a battery symbol). Ensure correct polarity (+ to + and - to -). The controller will automatically detect the battery voltage (12V o 24V).
2. Collegare il pannello solare: Collegare il pannello solare ai terminali del controller (contrassegnati dal simbolo del pannello solare). Assicurarsi che la polarità sia corretta.
3. Collegare il carico: Connect your DC loads to the controller's load terminals (marked with a light bulb symbol). Ensure correct polarity.

Important: Always connect the battery first and disconnect the load first, then the solar panel, and finally the battery when disassembling the system.

6. Istruzioni per l'uso

The controller features an LCD display and control buttons for monitoring and adjusting settings.

6.1. Display LCD

Il display LCD fornisce informazioni in tempo reale sul tuo impianto solare, tra cui:

• Pannello solare voltage e lo stato di carica.
• Volume della batteriatage e livello di carica.
• Load status (on/off) and current.
• Volume di sistematage (12V o 24V).

6.2. Regolazione del volumetage Impostazioni

The controller allows for manual adjustment of certain voltage parameters, such as the over-discharge recovery voltage. If you encounter issues or need to fine-tune your system, you can adjust the voltage:

1. Press and hold the MCU control button (usually the 'Menu' or 'Set' button) for approximately 3-4 seconds. This will bring up a management interface on the display.
2. Use the 'Add' button (or 'Up' arrow) to navigate through the settings and increase the voltage value until it reaches your desired setting, for example, 13.7V for battery recovery.
3. Press the MCU control button again to save the new setting. The display will stop flashing, indicating the data has been saved.

6.3. USB Output Usage

The dual USB ports can be used to charge various 5V devices, such as mobile phones, driving recorders, and cameras.

7. Manutenzione

Una manutenzione regolare garantisce prestazioni ottimali e longevità del regolatore di carica solare.

• Pulizia: Periodically clean the controller's exterior with a dry cloth to remove dust and dirt. Ensure the display remains clear.
• Verifica della connessione: Annually inspect all wiring connections to ensure they are secure and free from corrosion. Loose connections can cause overheating and damage.
• Ventilazione: Assicurarsi che l'area di installazione sia ben ventilata per evitare il surriscaldamento del controller.

8. Risoluzione Dei Problemi

Questa sezione affronta i problemi più comuni e le relative soluzioni.

8.1. No Output from Load Terminals

• sintomo: The load connected to the controller is not receiving power.
• Possibile causa: Volume della batteriatage is too low. The controller automatically stops output when battery voltage drops below a certain threshold (e.g., 10.5V-11V for a 12V system) to protect the battery from over-discharge.
• Soluzione: Allow the solar panel to charge the battery. The controller will resume load output once the battery voltage recovers to 12.6V (for a 12V system).

8.2. Vol. erratotage Readings or Charging Behavior

• sintomo: The display shows unexpected voltage values, or charging seems inefficient.
• Possibile causa: Voltage settings may be misconfigured or require adjustment. The normal operating voltage range for the controller is typically 10.7V to 13.7V (for a 12V system).
• Soluzione: Refer to Section 6.2 "Adjusting Voltage Settings" to manually adjust the voltage parameters, such as setting the recovery voltage to 13.7V if needed.
