Analysis of the power-on trip problem of Delta inverter
In life and production, leakage switches are often used. But the inverter is not used much at some times. Most manufacturers often use leakage switches as the main switch when installing switches in the workshop. When the frequency conversion control is elected, the problem comes out, and the leakage switch is always tripped after a little moment...
