Description
The standards of certain
countries and regions
require that the inverter
must not connect to the
power grid when the
power grid frequency is
higher than the upper
limit.
The standards of certain

Specifies the voltage
threshold for triggering
reactive power
compensation when LVRT
occurs.
Specifies the voltage
threshold for exiting
reactive power
compensation when the
inverter recovers from
LVRT.
Specifies the inverter
working mode based on
the grounding status at the
DC side and the
connection to the power
grid.
Description
Specifies the inverter
protection threshold in
the case of unbalanced
