Parameters
No.
Category Parameter Description
1 Insulation
resistance
protection
threshold
Insulation
resistance
protection
threshold (MΩ)
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.
2 Anti-islanding
protection
Active islanding
protection
Species whether to enable the
active islanding protection
function.
3 Passive islanding
protection
Species whether to enable the
passive islanding protection
function.
4 Voltage
protection
Unbalance voltage
protection
threshold (%)
Species the device protection
threshold when the power grid
voltage is unbalanced.
5 Phase protection
point (º)
The Japanese standard requires
that during passive islanding
detection, protection should be
triggered if an abrupt voltage
phase change is detected.
