7.2 Operations with the SUN2000 App
● 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 aected.
● Delivering a reset, shutdown, or upgrade command to the solar inverters may
cause power grid connection failure, which aects the energy yield.
● Before the equipment is put into operation for the rst time, ensure that the
parameters are set correctly by professional personnel. Incorrect parameter
settings may result in noncompliance with local grid connection requirements
and aect the normal operations of the equipment.
● The app screenshots in this chapter are for the SUN2000-60KTL-M0.
