Description
Specifies the LVRT/HVRT recovery threshold.
Specifies the LVRT or HVRT threshold for
triggering a transient voltage jump of a power
grid. A transient voltage jump indicates that the
inverter cannot immediately disconnect from
the power grid when the power grid is
abnormal due to transient changes.
Certain countries and regions have
requirements on the output current during
high/low voltage ride-through. In this case, set
this parameter to Enable. After this parameter
is set to Enable, the output current is less than
10% of the rated current during high/low
voltage ride-through.
Specifies whether to enable the active islanding
protection function.
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.
