- Cabos de conexão: Open the accessory pouch on the back of the panel to access the integrated MC4 cable and the 4-in-1 adapter cable.
- Selecione o conector: Select the appropriate connector from the 4-in-1 adapter cable (XT60, DC5525, Anderson, or DC7909) that matches your power station or battery input.
- Conectar ao dispositivo: Connect the MC4 cable from the solar panel to the 4-in-1 adapter cable, and then connect the chosen adapter to your compatible power station or battery. Ensure all connections are secure.

5. Instruções de operação
Once set up, your Voominhtec solar panel will begin converting sunlight into electricity. Here are some tips for optimal operation:
- Maximize a exposição à luz solar: Position the panel to receive maximum direct sunlight throughout the day. Adjust its angle periodically as the sun moves across the sky.
- Obstruções claras: Ensure no shadows from trees, buildings, or other objects fall on the panel, as even partial shading can significantly reduce efficiency.
- Carregamento do monitor: Most compatible power stations will display the incoming wattage. Monitor this to ensure the panel is performing as expected.
- Compatibilidade: The panel is widely compatible with most solar generators on the market, including Jackery, Ecoflow, Bluetti, and Anker. For charging 12V/24V batteries (USE, GEL, LI, FLD, SLD), an MPPT controller and alligator clips (not included) are required.
