Description
Specifies whether to shield
the undervoltage protection
function during LVRT.
During LVRT, the inverter
needs to generate reactive
power to support the power
grid. This parameter is used
to set the reactive power
generated by the inverter.
When the power grid
voltage is abnormally high
for a short time, the
inverter cannot disconnect
from the power grid
immediately and has to
work for some time. This is
called HVRT.
Specifies the threshold for
triggering the HVRT. The
threshold settings should
meet the local grid
standard.
Specifies whether to enable
the active islanding
protection function.
Specifies whether to enable
the passive islanding
protection function.

Remarks
This parameter is

is set to Enable.
This parameter is
displayed when LVRT
is set to Enable.
This parameter is set to
2.5 by default if the
South African grid
code is selected.
For example, if you set
LVRT reactive power
compensation power
factor to 2, the
reactive power
generated by the
inverter is 20% of the
rated power when the
AC voltage drops by
10% during LVRT.
N/A
This parameter is
displayed when HVRT
is set to Enable.

Japanese grid code is
selected.
