Description
Specifies the threshold for
triggering LVRT.
Specifies whether to shield
the undervoltage protection
function during LVRT.
During LVRT, the
SUN2000L needs to
generate reactive power to
support the power grid. This
parameter specifies the
reactive power generated by
the SUN2000L.
When the grid voltage is
abnormally high for a short
time, the SUN2000L cannot
disconnect from the power
grid immediately and has to
work for some time. This is
called high voltage
ride-through (HVRT).
Specifies the threshold for
triggering HVRT.
Specifies whether to enable
the active islanding
protection function.
Specifies whether to enable
the passive islanding
protection function.
The SUN2000L model
described in this document
does not support this
function. This function is
supported only by the model
with "-JP".
For a specific grid code
requires that the active
power of the SUN2000L be
derated according to a
certain slope when the
output voltage exceeds a
certain value.
