Parameter
Description
Power quality
If this parameter is set to
optimization
Enable, the inverter output
mode
current harmonics will be
optimized.
PID protection
When the inverter outputs
at night
reactive power at night and
this parameter is set to
Enable, the inverter will shut
down automatically if it
detects abnormal status of
the PID compensation.
HVRT
HVRT is short for high
voltage ride-through. When
the grid voltage is abnormally
high for a short time, the
device cannot disconnect
from the power grid
immediately and must
continue to operate for some
time.
HVRT triggering
Specifies the threshold for
threshold (V)
triggering HVRT. The
threshold settings should
meet the local grid standard.
HVRT gradient
During HVRT, the device must
K1
generate positive-sequence
reactive power to support the
power grid. This parameter is
used to set the positive-
sequence reactive power
generated by the device.
For example, if you set HVRT
gradient K1 to 2, the
increment of positive-
sequence reactive current
generated by the device is
20% of the rated current
when the AC voltage
increases by 10% during
HVRT.
