When the grid voltage is
abnormally low for a short
time, the SUN2000L cannot
disconnect from the power
grid immediately and has to
work for some time. This is
called low voltage
ride-through (LVRT).
Anti-islanding protection
Specifies whether to enable
the active islanding
protection function.
Specifies whether to enable
the passive islanding
protection function.
The Japanese 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.
V rise suppress reactive
adjust point (V)
For a specific grid code
requires that the SUN2000
generate a certain amount of
reactive power when the
output voltage exceeds a
certain value. This
parameter is displayed when
Voltage rise suppression is
set to Enable.
V rise suppress active
derating point (V)
For a specific grid code
requires that the active
power of the SUN2000 be
derated according to a
certain slope when the
output voltage exceeds a
certain value. This
parameter is displayed when
Voltage rise suppression is
set to Enable. V rise
suppress active derating pt
must be greater than V rise
suppress reactive adjust pt.
Soft start time after grid
failure (s)
Specifies the time for the
power to gradually increase
when the SUN2000L
restarts after the power grid
recovers.
