12V to 220V 4000W Pure Sine Wave Inverter Dual AC with Remote Control and LCD Digital Display

Features: 1. The dual LCD digital display allows you to monitor the output voltage and battery voltage at all times. 2. Fault prompt function. In addition to various audible prompts, faults can also be displayed more intuitively on the screen (e.g., battery undervoltage, battery overvoltage, overload, high operating temperature, output short circuit, etc.). 3. Overload delay shutdown function has been added to address the critical issue of inverter protection when a high-power electrical device is switched on. 4. Positive and negative reverse polarity protection has been added for the low-power, non-professional user market. 5. Intelligent temperature-controlled oil-sealed fan. When the inverter is running, it can operate at a specific temperature, which is more energy-efficient.
