Huawei SUN2000 Series - Setting Protection Parameters

No. Parameter Description
6 Grid reconnection
voltage upper limit (V)
The standards of certain countries and regions require that after
the inverter shuts down for protection due to a fault, if the
power grid voltage is higher than Grid reconnection voltage
upper limit, the inverter is not allowed to reconnect to the grid.
7 Grid reconnection
voltage lower limit (V)
The standards of certain countries and regions require that after
the inverter shuts down for protection due to a fault, if the
power grid voltage is lower than Grid reconnection voltage
lower limit, the inverter is not allowed to reconnect to the grid.
8 Grid reconnection
frequency upper limit
(Hz)
The standards of certain countries and regions require that after
the inverter shuts down for protection due to a fault, if the
power grid frequency is higher than Grid reconnection
frequency upper limit, the inverter is not allowed to reconnect
to the grid.
9 Grid reconnection
frequency lower limit
(Hz)
The standards of certain countries and regions require that after
the inverter shuts down for protection due to a fault, if the
power grid frequency is lower than Grid reconnection
frequency lower limit, the inverter is not allowed to reconnect
to the grid.
