4. Configuració

4.1. Desembalatge i inspecció

1. Carefully unpack the inverter from its packaging.
2. Inspect the unit for any visible damage that may have occurred during transit. If damage is found, contact your supplier immediately.
3. Verify that all accessories listed in the packing list are present.

4.2. Muntatge de l'inversor

Choose a suitable location for mounting the inverter, considering the following:

• Ventilació: Ensure adequate clearance (at least 20 cm) around the inverter for proper airflow.
• Medi ambient: Mount in a dry, dust-free area, away from direct sunlight and heat sources.
• Suport estructural: The mounting surface must be strong enough to support the inverter's weight (approximately 44.1 pounds).
• Accessibilitat: Ensure easy access for wiring, operation, and maintenance.

Use appropriate mounting hardware (not included) to securely fasten the inverter to a vertical surface.

4.3. Connexions de cablejat

All wiring must comply with local electrical codes and regulations. Use appropriately sized cables for all connections.

1. Posada a terra: Connect the inverter's ground terminal to a reliable earth ground.
2. Connexió de la bateria: Connect the battery bank to the inverter's battery terminals. Ensure correct polarity (+ to + and - to -). Install a DC circuit breaker between the battery and inverter.
3. Connexió del panell solar: Connect the solar panel array to the PV input terminals. Observe correct polarity and ensure the open-circuit voltage (Voc) and short-circuit current (Isc) are within the inverter's specifications. Install a DC circuit breaker between the solar array and inverter.
4. Entrada de CA (xarxa/generador): If connecting to an AC grid or generator, connect the AC input to the designated terminals. Install an AC circuit breaker.
5. Sortida de CA (càrregues): Connect your AC loads to the inverter's AC output terminals. Install an AC circuit breaker.

Important: Double-check all connections for tightness and correct polarity before proceeding. Incorrect wiring can cause severe damage to the inverter and pose a safety risk.
