Parameter
Description
Remarks
HVRT
compensation
power factor of
reactive power in
positive sequence
During HVRT, the solar inverter needs to
generate positive-sequence reactive power
to support the power grid. This parameter
is used to set the positive-sequence
reactive power generated by the solar
inverter.
For example, if you set HVRT
compensation power factor of reactive
power in positive sequence to 2, the
increment of positive-sequence reactive
current generated by the solar inverter is
20% of the rated current when the AC
voltage increases by 10% during HVRT.
LVRT
undervoltage
protection shield
Specifies whether to shield the
undervoltage protection function during
LVRT.
This parameter is displayed
when LVRT is set to Enable.
Grid voltage
protection shield
during VRT
Specifies whether to shield the
undervoltage protection function during
LVRT or HVRT.
This parameter is displayed
when LVRT or HVRT is set to
Enable.
VRT active
current limiting
(%)
Specifies the percentage of the maximum
active current to the rated current during
fault ride-through (FRT).
-
VRT active power
recovery gradient
Specifies the recovery rate when the active
current recovers to the value at the
moment before FRT.
-
Grid voltage
jump triggering
threshold (%)
Specifies the LVRT or HVRT threshold for
triggering a transient voltage jump of a
power grid. A transient voltage jump
indicates that the inverter cannot
immediately disconnect from the power
grid when the power grid is abnormal due
to transient changes.
This parameter is available when
Grid code is set to VDE 4120.
Zero current due
to power grid
fault
Certain countries and regions have
requirements on the output current during
high/low voltage ride-through. In this case,
set this parameter to Enable. After this
parameter is set to Enable, the output
current is less than 10% of the rated
current during high/low voltage ride-
through.
This parameter is displayed
when LVRT or HVRT is set to
Enable.
Active islanding
protection
Specifies whether to enable the active
islanding protection function.
-
Passive islanding
protection
Specifies whether to enable the passive
islanding protection function.
This parameter is displayed if
the Japanese grid code is
selected.
