4. Instal·lació i configuració
4.1 Muntatge a la paret
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 connexió del sistema
Figure 4.1: Basic application diagram showing the connections between solar panels, utility grid, generator, inverter, battery, and home loads. Note: Generator, PV modules, WiFi module, and battery are not included with the inverter unless specified.
4.3 Connexions de cablejat
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.
- Connexió del panell 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 és 120 VDC.
- Connexió de la 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 de CA (xarxa/generador): Connect the AC utility grid or a generator to the AC input terminals. This provides backup power and can charge batteries.
- Sortida de CA (càrregues): Connect your household loads to the AC output terminals.
4.4 Engegada inicial
After all connections are made and verified:
- Engegueu l'interruptor de la bateria.
- Turn on the solar panel breaker (if applicable).
- Turn on the AC input breaker (if connected to grid/generator).
- Engegueu l'interruptor d'alimentació de l'inversor.
- Observe the display for status indicators and initial readings.
5. Modes de funcionament
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.
- Mode de prioritat de la bateria: The inverter prioritizes drawing power from the batteries. Solar energy will charge the batteries. The utility grid is used only when battery voltage drops below a set threshold.
- 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 Seguiment
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.
