Parameter List
Parameter Description Remarks
Automatic OFF due
to communication
interrupted
The standards of certain countries and
regions require that the inverter must
shut down after the communication is
interrupted for a certain time.
If Automatic OFF due to
communication interrupted is
set to Enable and the inverter
communication is interrupted for
a specied time (set by
Communication interruption
duration), the inverter will
automatically shut down.
Automatic ON due
to communication
resumed
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.
This parameter is displayed when
Automatic OFF due to
communication interrupted is
set to Enable.
Communication
interruption
duration (min)
Species the duration for determining
communication interruption. Used for
automatic shutdown for protection in
case of communication interruption.
N/A
Soft start/boot time
(s)
Species the duration for the power to
gradually increase when the inverter
starts.
N/A
LVRT 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.
N/A
LVRT threshold (V) Species the threshold for triggering
LVRT.
The threshold settings should meet the
local grid standard.
This parameter is displayed when
LVRT is set to Enable.
LVRT reactive power
compensation
power factor
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.
● This parameter is displayed
when LVRT is set to Enable.
● For example, if this parameter
is set to 2, the reactive power
generated by the inverter is
20% of the rated power when
the AC voltage drops by 10%
during LVRT.
