Features: 1. Dual LCD digital display allows you to monitor output voltage and battery voltage at any time. 2. Fault alert function. In addition to audible alerts, issues such as battery undervoltage, battery overvoltage, overload, high operating temperature, and output short circuit are clearly displayed on the screen. 3. Overload delay shutdown function helps prevent inverter shutdown during startup of motor-driven appliances. 4. Includes reverse polarity protection for non-professional, small-power user applications. 5. Intelligent temperature-controlled fan provides efficient cooling while maintaining low noise and energy efficiency. 6. Digital MCU control ensures stable output waveform, accurate frequency, precise output voltage, and fast response protection circuit. Suitable for use in cars, boats, mobile communications, public safety, emergency services, and other fields.
