Description
To ensure device safety, the
SUN2000L detects the
insulation resistance of the
input side to the ground
when it starts a self-check. If
the detected value is less
than the preset value, the
SUN2000L does not start.
The Japanese standard
requires that during passive
islanding detection,
protection should be
triggered if an abrupt
voltage phase change is
detected.
The SUN2000L model
described in this document
does not support this
function. This function is
supported only by the model
with "-JP".
Under a specific grid code,
the SUN2000L needs to be
protected when the phase
angle offset of the three
phases of the power grid
exceeds a certain value.
