Table 7-9 Description of protection parameters
Ins R protection threshold
(MΩ)
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.
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.
The SUN2000L model
described in this document
does not support this
function. This function is
supported only by the model
with "-JP".
Phase angle offset
protection
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.
10-min OV protection
threshold (V)
Specifies the 10-minute
overvoltage protection
threshold.
10-min OV protection
duration (ms)
Specifies the 10-minute
overvoltage protection
duration.
Level-1 OV protection
threshold (V)
Specifies the level-1
overvoltage protection
threshold.
Level-1 OV protection
duration (ms)
Specifies the level-1
overvoltage protection
duration.
Level-2 OV protection
threshold (V)
Specifies the level-2
overvoltage protection
threshold.
Level-2 OV protection
duration (ms)
Specifies the level-2
overvoltage protection
duration.
