LVRT
undervoltage
protection
shield
Specifies whether to shield
the undervoltage protection
function during LVRT.
N/A
Disable
Enable
This parameter is
displayed when
LVRT
is set to
Enable
.
4
LVRT
reactive
power
compensation
power factor
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.
N/A
[0, 3]
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.
5
HVRT
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.
N/A
Disable
Enable
N/A
6
HVRT
triggering
threshold
Specifies the threshold for
triggering the HVRT. The
threshold settings should
meet the local grid
standard.
V
[105%Vn,
130%Vn]
This parameter is
displayed when
HVRT
is set to
Enable
.
7
Active
islanding
Specifies whether to enable
the active islanding
protection function.
N/A
Disable
Enable
N/A
8
Passive
islanding
Specifies whether to enable
the passive islanding
protection function.
N/A
Disable
Enable
This parameter is
displayed after the
Japanese grid code is
selected.
