Please read this manual thoroughly before installation and operation to ensure proper use and to prevent damage to the inverter or connected devices.

2. Informações de segurança

Adhering to these safety guidelines is crucial for preventing personal injury and damage to the inverter or other equipment.

• Segurança elétrica: Always ensure the inverter is disconnected from the battery before performing any maintenance or connection adjustments. Work in a dry environment and avoid contact with water.
• Ventilação: The inverter generates heat during operation. Ensure adequate ventilation around the unit. Do not block the cooling fans or vents. The inverter is equipped with dual cooling fans for efficient heat dissipation.
• Compatibilidade da bateria: This specific model is designed for a 12V DC input. Ensure your battery system matches this voltage. Connecting to an incorrect voltage can damage the inverter.
• Capacidade de carga: Do not exceed the inverter's rated output power (4000W). Overloading can cause the inverter to shut down or be damaged. Refer to the specifications for continuous and peak power ratings.
• Polaridade: Always connect the battery cables with correct polarity (positive to positive, negative to negative). Reverse polarity connection will trigger protection but can still cause damage over time.
• Recursos de proteção: The inverter includes multiple built-in protections: overload protection, overheating protection, high and low voltage protection, short circuit protection, and reverse polarity protection. While these features enhance safety, they are not substitutes for proper handling.
• Compatibilidade de frequência: This inverter outputs 220V AC. Verify that the output frequency (e.g., 50Hz or 60Hz) of your specific inverter model matches the requirements of the appliances you intend to power and your regional standard. Incorrect frequency can damage sensitive electronics.
• Crianças e animais de estimação: Mantenha o inversor fora do alcance de crianças e animais de estimação.

4. Configuração e instalação

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

4.1 Escolhendo um local

• Select a cool, dry, and well-ventilated area.
• Evite a luz solar direta, fontes de calor e umidade.
• 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 gota.

1. Certifique-se de que o interruptor de alimentação do inversor esteja na posição "DESLIGADO".
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. Certifique-se de que todas as conexões estejam firmes e seguras para evitar arcos elétricos e superaquecimento.

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.
