Description
The standards of certain countries and
regions require that the inverter must
shut down after the communication is
interrupted for a certain time.
If this parameter is set to Enable, the
inverter automatically starts after
communication recovers. If this
parameter is set to Disable, the
inverter needs to be started manually
after communication recovers.
Specifies the duration for determining
communication interruption. Used for
automatic shutdown for protection in
case of communication interruption.
Specifies the duration for the power to
gradually increase when the inverter
starts.
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.

Remarks
If Automatic OFF due to
communication interrupted is
set to Enable and the inverter
communication is interrupted for
a specified time (set by
Communication interruption
duration), the inverter will
automatically shut down.
This parameter is displayed when
Automatic OFF due to
communication interrupted is
set to Enable.

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.
