Description
Specifies the inverter protection threshold when the power grid
voltage is unbalanced.
To ensure device safety, the inverter detects the insulation
resistance of the input side with respect to ground when it
starts a self-check. If the detected value is less than the preset
value, the inverter does not connect to the grid.
The standards of certain countries and regions require that the
inverter needs to be protected when the phase angle offset of
the power grid three phases exceeds a certain value.
