Why does the output voltage on the display always show 220V without any change?
If the output voltage is 140V-260V, then the output voltage will be 220V±8%. When the voltage is between 202V-238V, there will be no change on the display. If you need, we can modify the program of the display to show the actual output voltage.

Power consumption problem
The first problem is that the small main current is not directly related to the power consumption. The second question is that it is generally believed that assembling a voltage regulator in front of the electric meter can reduce power consumption, but it is necessary to pay attention to whether local regulations require this, and […]
Whats is delay proteciton?
After starting, it will wait 180s to 6s to be able to work. It’s to prevent instantaneous voltage impact on electrical appliances.
