It has more stable quality than high frequency inverters'. Even it works with inductive loads, it will also protection loads with 3 times of rated power protection. And it can also work longer upon battery capacity. So power inverter apply for your commerical, industrial, household applications.      It has two working modes. The first working mode is inverter mode. When grid power is outage, it will change to inverter mode; when grid power is up&down, it will stabilize the input voltage and output stable power.
