7.1.4.3 Setting Feature Parameters
Choose Settings > Feature parameters to set feature parameters.
No. Parameter Description Remarks
1 MPPT multi-peak
scanning
When the inverter is used in
scenarios where PV strings are
greatly shaded, set this parameter
to Enable, and then the inverter
will perform MPPT scanning at
regular intervals to locate the
maximum power.
-
2 MPPT multi-peak
scan interval (min)
Species the MPPT scanning
interval.
This parameter is displayed
when MPPT multi-peak
scanning is set to Enable.
3 LVRT LVRT is short for low voltage ride-
through. When the grid voltage is
abnormally low for a short time,
the inverter cannot disconnect
from the power grid immediately
and has to work for some time.
-
4 LVRT triggering
threshold (V)
Species the threshold for
triggering LVRT. The threshold
settings should meet the local
grid standard.
This parameter is displayed
when LVRT is set to Enable.
5 LVRT gradient K1 During LVRT, 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 LVRT
gradient K1 to 2, the increment
of positive-sequence reactive
current generated by the solar
inverter is 20% of the rated
current when the AC voltage
decreases by 10% during LVRT.
