4. نصب کول

ستاسو د انورټر د خوندي او موثر فعالیت لپاره سم نصب کول خورا مهم دي. دا ګامونه په دقت سره تعقیب کړئ.

4.1 د انورټر نصب کول

• Choose a dry, well-ventilated location away from direct sunlight, heat sources, and moisture.
• Mount the inverter on a non-combustible surface.
• Ensure there is at least 6 inches (15 cm) of clear space around all sides of the inverter for proper airflow.
• Use appropriate fasteners to secure the inverter firmly to the mounting surface.

4.2 DC ان پټ اتصال

خبرداری: Ensure the battery bank is disconnected or isolated before making any connections. Use appropriately sized cables and fuses/breakers.

1. Connect the positive (+) DC cable (typically red) from your 48VDC battery bank to the red positive (+) terminal on the inverter's rear panel.
2. Connect the negative (-) DC cable (typically black) from your 48VDC battery bank to the black negative (-) terminal on the inverter's rear panel.
3. Ensure all DC connections are tight and secure to prevent loose connections and arcing.
4. Install an external DC fuse or circuit breaker between the battery bank and the inverter's positive terminal, as close to the battery as possible. Consult the specifications for appropriate fuse sizing.

4.3 د AC آوټ پټ کنکشن

The SP-4000-148 uses a hardwire AC output connection.

1. Ensure the inverter is OFF and all DC power is disconnected.
2. Connect your AC load wiring to the designated AC output terminal block on the front panel.
3. Follow all local electrical codes for AC wiring.
4. Ensure all AC connections are secure.

4.4 ځمکني کول
