Pure Sine Wave Power Inverter 4000W 5000W DC 12V 24V 48V To AC220V Portable Power Bank Converter Solar Car Inverter Transformer

Equipped with eight-bit intelligent protection: overload protection, high voltage protection, low voltage protection, overheating protection, reverse connection protection, short circuit protection, overcurrent protection and insurance protection. The protection functions are managed by an intelligent control chip. An intelligent temperature-controlled fan reduces noise: when the temperature is 45 the fan stops; when the temperature is 45 the fan starts. If any protection is triggered the inverter immediately cuts output and the load enters protection mode while a buzzer provides an audible alert. High-voltage protection thresholds: (For inverter with 12V input, voltage lower than 10.5V or higher than 15V will trigger automatic protection and power disconnection) (For inverter with 24V input, voltage lower than 20V or higher than 29V will trigger automatic protection and power disconnection). When connecting via the vehicle cigarette lighter lead, do not exceed 300W (12V car) or 400W (24V truck).
