Aluminum alloy shell, light weight, good thermal conductivity, can quickly reduce the temperature of components, long-term work is not affected. Pure sine wave, intelligent filtering, no interference with electrical appliances and protection of electrical appliances. High conversion efficiency (up to 90%), the low power consumption of the product itself can greatly extend the battery life. Can use electrical appliances, including TV/LED lights/LCD, especially refrigerators, freezers, induction cookers and other inductive load appliances. Buzzer alert. Once the protection of the inverter is triggered, the inverter will immediately turn off the power and the load will enter the protection mode and alert people through the buzzer. Wide use:Our inverter is pure sine wave inverter, you can use some electrical appliances with high requirement of electric wave such as boiler, cutting machine, microwave oven etc. through him
