Proper installation is critical for the inverter's performance and safety.

4.1 Ịhọrọ ebe

• Select a cool, dry, and well-ventilated area.
• Zere ìhè anyanwụ kpọmkwem, ebe okpomọkụ na-esi apụta, na mmiri mmiri.
• Ensure there is sufficient space around the inverter for air circulation, especially around the cooling fans.
• Mount the inverter securely to prevent movement or accidental dislodgement.

4.2 Connecting to a Battery System

This inverter requires a 12V DC battery system. For optimal performance and safety, use appropriate gauge cables for your inverter's wattage and cable length. Shorter, thicker cables are recommended to minimize voltage dobe.

1. Ensure the inverter's power switch is in the "OFF" position.
2. Connect the positive (+) terminal of the inverter to the positive (+) terminal of the 12V battery.
3. Connect the negative (-) terminal of the inverter to the negative (-) terminal of the 12V battery.
4. Ensure all connections are tight and secure to prevent arcing and overheating.

4.3 Connecting to a Car (for lower wattage models or specific applications)

While the 4000W model typically requires direct battery connection due to high current draw, some lower wattage variants of this product line may support connection via a car cigarette lighter socket. If your specific model supports this, ensure the vehicle's electrical system can handle the load. For the 4000W model, direct connection to the vehicle's main battery is mandatory.
