Description
Specifies the grid
undervoltage protection
threshold.
Specifies the grid
undervoltage protection
duration.
Specifies the level-1
overvoltage protection.
When the power grid
voltage is abnormally
low for a short time, the
inverter cannot
disconnect from the
power grid immediately
and has to work for some
time. This is called
LVRT.
Specifies whether to
enable the active
islanding protection
function.
Specifies whether to
enable the passive
islanding protection
function.
The Japanese standard
requires that during
passive islanding
detection, protection
should be triggered if an
abrupt voltage phase
change is detected.
Refers to a control
module that calculates
the reactive power based
on the offset deviation of
grid frequency and
promotes frequency
offset when islanding
occurs.
