2. Safety Instructions

Please read and understand all safety instructions before operating the inverter. Failure to follow these instructions may result in electric shock, fire, or serious injury.

• Proper Ventilation: Ensure the inverter is installed in a well-ventilated area. Do not block the ventilation openings.
• Avoid Moisture: Do not expose the inverter to rain, water, or excessive moisture.
• Correct Voltage: Connect the inverter only to a 24V DC power source. Connecting to an incorrect voltage may damage the unit.
• Polarity: Always ensure correct polarity when connecting the DC input cables. Reverse polarity protection is built-in, but incorrect connection can still cause issues.
• Load Capacity: Do not exceed the inverter's continuous power rating of 3500W. The peak power is 7000W for short durations.
• Spark Protection: The inverter is equipped with a professional spark protection circuit that automatically stops output if the power supply is incorrectly connected or a short circuit occurs.
• Temperature: The smart dual fans activate automatically when the internal temperature reaches 45°C to prevent overheating.
• Children and Pets: Keep the inverter out of reach of children and pets.
