8 Device Commissioning
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 whether to enable the
passive islanding protection
function.
Specifies the device protection
threshold when the power grid
voltage is unbalanced.
The Japanese standard requires
that during passive islanding
detection, protection should be
triggered if an abrupt voltage
phase change is detected.
