4.2 Procediment de connexió

  1. Connecta la bateria: Connect a 3.7V rechargeable Li-ion battery to the BATT interfaces (4). Ensure correct polarity. The module does not include a battery holder, so batteries must be purchased separately.
  2. Connect Solar Panel (Optional): Connect a 6V-24V solar panel to the Solar panel charging input (1). The module supports self-adaptive input voltage.
  3. Connect Type-C Power Adapter (Optional): Alternatively, or in addition to solar, connect a 5V Type-C power adapter to the Type-C charging input (2) for battery charging.
  4. Connectar càrrega: Connect your 5V device to the Power output (3) screw terminal. Ensure the device's current draw does not exceed 3A.

Important: Always ensure correct polarity for all connections to prevent damage to the module and connected devices.

5. Instruccions de funcionament

5.1 Càrrega de la bateria

  • Càrrega solar: When a solar panel is connected and exposed to sufficient sunlight, the module will automatically begin charging the connected 3.7V Li-ion battery. The "Charge" LED (part of Solar panel charging indicators, 9) will illuminate. Once the battery is fully charged, the "Done" LED will light up.
  • Càrrega tipus C: Connect a 5V Type-C power adapter to the Type-C input (2). The module will charge the battery. The BATT capacity indicators (8) will show the charging progress.

5.2 Powering External Devices

  • The module provides a regulated 5V/3A output via the screw terminal (3). Connect your 5V device to this output.
  • The Type-C port (2) can also function as a 5V output for external devices when not used for charging.

5.3 Indicadors LED

  • BATT Capacity Indicators (8): These LEDs light up when the battery is charging or under load. They will turn off approximately 30 seconds after the load is removed.
  • Solar Panel Charging Indicators (9):
    • Càrrec: Illuminates when the solar panel is actively charging the battery.
    • Fet: Illuminates when the battery is fully charged by the solar panel.

6. Manteniment

  • Neteja: Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using liquids or abrasive cleaners.
  • Connexions: Periodically check all screw terminal connections to ensure they are secure. Loose connections can lead to poor performance or damage.
