12V 220V Pure Sine Wave Inverter 4000W Pure Sine Wave Power Inverter Transformer with Remote Control and Dual AC Outlets Features: 1. Dual LCD digital display allows you to maintain the output voltage and battery voltage value at any time. 2. Fault prompt function. In addition to various sound prompts, it can also be displayed more intuitively from the display screen (e.g., battery undervoltage, battery overvoltage, overload, high operating temperature, output short circuit, etc.). 3. The overload delay closing function is added to the product to solve the sensitive problem of inverter protection when the soluble electrical appliance is started. 4. The positive and negative pole reverse protection function has been added for the small power non-professional user market. 5. Intelligent temperature control oil-sealed fan. When the inverter is working, it can operate at a certain temperature, which is more energy-saving. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
