Pure Sine Wave Inverter 4000W/5000W — DC 12V/24V/48V to AC220V Portable Power Bank Converter for Solar & Car

Eight-bit intelligent protection managed by an intelligent chip: overload protection, high voltage protection, low voltage protection, overheating protection, reverse connection protection, short circuit protection, overcurrent protection and insurance protection. Intelligent temperature-control fan for quieter operation — when the temperature is 45 the fan stops working; when the temperature is 45 the fan starts working. Built-in buzzer reminder: if any protection is activated the inverter will immediately cut power, enter protection mode and sound the buzzer. High voltage protection specifics: (Inverter with 12V input and voltage lower than 10.5V or voltage higher than 15V will automatically protect and disconnect the power supply) (Inverter with 24V input and voltage lower than 20V or voltage higher than 29V will automatically protect and disconnect the power supply). When using 12V / 24V via the cigarette lighter cable in a vehicle, do not exceed 300W (12V car) or 400W (24V truck).
