Description
To ensure its safety, the device
detects the insulation resistance of
the DC side to the ground when it
starts a self-check. If the detected
value is less than the preset value,
the device does not connect to the
grid.
Specifies whether to enable the
active islanding protection
function.
Specifies the device protection
threshold when the power grid
voltage is unbalanced.
The standards of certain countries
and regions require the device be
protected when the phase angle
offset of the power grid three
phases exceeds a certain value.
Specifies the 10-minute
overvoltage protection threshold.
