5. Setup and Installation

Follow these steps for proper installation of your OLTEANP inverter:

5.1 Mounting the Inverter

• Choose a mounting location that is dry, cool, well-ventilated, and away from direct sunlight or heat sources.
• Ensure there is sufficient space around the inverter for airflow and access to connections.
• Securely mount the inverter using appropriate hardware for the chosen surface.

5.2 Battery Connection

Important: Ensure the inverter is OFF before making any connections.

• Connect the positive (+) terminal of the inverter to the positive (+) terminal of your 24V battery bank using the red battery cable.
• Connect the negative (-) terminal of the inverter to the negative (-) terminal of your 24V battery bank using the black battery cable.
• Ensure all connections are tight and secure to prevent loose connections and overheating.

5.3 Grounding the Inverter

Proper grounding is crucial for safety and stable operation.

• Locate the grounding terminal on the inverter (usually marked with a ground symbol).
• Connect one end of the grounding wire to this terminal.
• Connect the other end of the grounding wire to a reliable earth ground point (e.g., vehicle chassis, ground rod).
