Description
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.
Specifies the MPPT scanning
interval.
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.
Specifies the threshold for
triggering LVRT. The threshold
settings should meet the local
grid standard.
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.
