NO TICE
● When you use the SUN2000 app to set parameters for the SUN2000, setting
items on certain parameter setting screens are not displayed if the AC switch
between the SUN2000 and the power grid is turned on but both of DC
SWITCH on the SUN2000 are not in the ON position. Switch both of DC
SWITCH to the ON position and then reset relevant parameters again.
● If you change the grid code, some parameters may be restored to factory
defaults. After the grid code is changed, check whether the previously set
parameters are
aected.
● Delivering a reset, shutdown, or upgrade command to the solar inverters may
cause power grid connection failure, which aects the energy yield.
● Only professionals are allowed to set the grid parameters, protection
parameters, feature parameters, and power adjustment parameters of the solar
inverters. If the grid parameters, protection parameters, and feature parameters
are incorrectly set, the solar inverters may not connect to the power grid. If the
power adjustment parameters are incorrectly set, the solar inverters may not
connect to the power grid as required. In these cases, the energy yield will be
aected.
NO TE
● Congurable parameters vary depending on the grid code. The actual display prevails.
