4. Instalação e configuração

4.1 Montagem na parede

The inverter is designed for wall mounting. Choose a location that is dry, well-ventilated, and protected from direct sunlight and moisture. Ensure sufficient clearance around the unit for proper airflow and heat dissipation. Use appropriate mounting hardware for your wall type.

4.2 Diagrama de Conexão do Sistema

4.3 Conexões de Fiação

Follow the diagram above and the labels on the inverter for correct wiring. Ensure all connections are secure and properly insulated. It is highly recommended that a qualified electrician performs all wiring.

• Conexão do painel solar: Connect your solar panels to the designated PV input terminals. Observe correct polarity (positive to positive, negative to negative). The maximum DC input voltage é 120 VDC.
• Conexão da bateria: Connect the 24V battery bank to the battery terminals. Ensure correct polarity. The inverter supports AGM, lead-acid, gel, and flooded lithium-ion batteries.
• Entrada CA (Rede/Gerador): Connect the AC utility grid or a generator to the AC input terminals. This provides backup power and can charge batteries.
• AC Output (Loads): Conecte os aparelhos elétricos da sua casa aos terminais de saída CA.

4.4 Inicialização

After all connections are made and verified:

1. Ligue o disjuntor da bateria.
2. Turn on the solar panel breaker (if applicable).
3. Ligue o disjuntor de entrada CA (se estiver conectado à rede elétrica/gerador).
4. Turn on the inverter's power switch.
5. Observe the display for status indicators and initial readings.

5. Modos de operação

The PNI GreenHouse SC1800C PRO offers intelligent energy management with several configurable operating modes:

• Solar Priority Mode (SBU): In this mode, the inverter prioritizes power consumption from solar energy. If solar power is insufficient, it will draw from batteries. The utility grid acts as a backup.
• Modo de prioridade da bateria: The inverter prioritizes drawing power from the batteries. Solar energy will charge the batteries. The utility grid is used only when battery voltage cai abaixo de um limite predefinido.
• Utility Priority Mode (UPS): This mode prioritizes power from the utility grid. Solar energy will charge the batteries. The inverter switches to battery power only when the grid is unavailable, functioning as an Uninterruptible Power Supply (UPS).

These modes can be configured via the inverter's multifunction display and dedicated menu for advanced settings.

5.1 Monitoramento

The inverter supports monitoring through:

• PC Software (USB): Connect the inverter to a PC using the provided USB cable and dedicated software for detailed monitoring and analysis of parameters.
• Remote Monitoring (WiFi - Optional): With the optional PNI Smart Dongle-WLAN, you can monitor the inverter remotely via a mobile application or web interface.

6. Manutenção

Regular maintenance ensures optimal performance and longevity of your inverter. Always disconnect all power sources before performing any maintenance.

• Limpeza: Limpe periodicamente a parte externa do inversor com um pano seco. Certifique-se de que as aberturas de ventilação estejam livres de poeira e detritos. Não utilize produtos de limpeza líquidos.
• Verificações de conexão: Annually inspect all wiring connections (solar, battery, AC input/output) for tightness and signs of corrosion. Tighten any loose connections.
• Inspeção da bateria: Se estiver usando baterias de chumbo-ácido, verifique os níveis de eletrólito e a condição dos terminais conforme as instruções do fabricante da bateria.
• Verificação ambiental: Assegure-se de que o ambiente de instalação permaneça dentro das faixas de temperatura e umidade especificadas.
