No. Parameter Description Remarks
10 Threshold for
triggering
HVRT (V)
Species the threshold for triggering HVRT. The
threshold settings should meet the local grid
standard.
This parameter is
displayed when HVRT
is set to Enable.
11 HVRT
gradient K1
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 gradient K1 to 2,
the positive-sequence reactive current
generated by the solar inverter is 20% of the
rated current when the AC voltage increases by
10% during HVRT.
12 HVRT
gradient K2
During HVRT, the solar inverter needs to
generate negative-sequence reactive power to
support the power grid. This parameter is used
to set the negative-sequence reactive power
generated by the solar inverter.
For example, if you set HVRT gradient K2 to 2,
the negative-sequence reactive current
generated by the solar inverter is 20% of the
rated current when the AC voltage increases by
10% during HVRT.
13 Grid voltage
protection
shield during
VRT
Species whether to shield the undervoltage
protection function during LVRT or HVRT.
This parameter is
displayed when LVRT
or HVRT is set to
Enable.
14 VRT exit
hysteresis
threshold
Species the LVRT/HVRT recovery threshold. ● This parameter is
displayed when
LVRT or HVRT is
set to Enable.
● LVRT recovery
threshold =
Threshold for
triggering LVRT +
VRT exit hysteresis
threshold
● HVRT recovery
threshold =
Threshold for
triggering HVRT -
VRT exit hysteresis
threshold
