Description
When the power grid voltage is
abnormally low for a short time, the
SUN2000 cannot disconnect from the
power grid immediately and has to
work for some time. This is called LVRT.
Specifies the threshold for triggering
LVRT.
The threshold settings should meet the
local grid standard.
Specifies whether to shield the
undervoltage protection function
during LVRT.
During LVRT, the SUN2000 needs to
generate reactive power to support the
power grid. This parameter is used to
set the reactive power generated by
the SUN2000.
When the power grid voltage is
abnormally high for a short time, the
SUN2000 cannot disconnect from the
power grid immediately and has to
work for some time. This is called high
voltage ride-through (HVRT).
Specifies the threshold for triggering
HVRT. The threshold settings should
meet the local grid standard.
During HVRT, the inverter needs to
generate reactive power to support the
power grid. This parameter is used to
set the reactive power generated by
the inverter.
Specifies the LVRT/HVRT recovery
threshold.

Remarks
N/A
Vn represents the rated voltage.
N/A
For example, if you set LVRT
reactive power compensation
power factor to 2, the reactive
current generated by the
SUN2000 is 20% of the rated
current when the AC voltage
drops by 10% during LVRT.
N/A
This parameter is displayed when
HVRT is set to Enable.
N/A
● 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
