Features:1. Dual LCD digital display allows you to maintain output voltage and battery voltage value at any time.2. Fault prompt function. In addition to the various sound prompts, it can also be displayed more intuitively from the display screen (eg, battery undervoltage, battery overvoltage, overload, high operating temperature, short- output circuit, etc.).3. The overload delay closing function is added in the product to solve the sensitive problem of inverter protection when the soluble electric appliance is started.4. The small-power non-professional user market has increased the positive and negative pole feedback protection function.5. Intelligent temperature control oil seal fan. When the inverter is working, it can work at a certain temperature, which is more energy-saving and quieter.6. Digital MCU control, output wave type, more accurate frequency, accurate output voltage, fast response protection circuit. in cars, steamships, mobile post and telecommunications, public
