● indicates the power ow direction, indicates the signal line, and
indicates the wireless communication.
● In the SUN2000 cascading scenario, the master and slave solar inverters are both
SUN2000-(2KTL-6KTL)-L1, and a maximum of three SUN2000s can be cascaded.
● In the SUN2000 cascading scenario, only one smart power sensor (G in the
gure) can
be connected to the master inverter.
● In the SUN2000 cascading scenario, the SUN2000s connected to the power grid must
meet the local power grid requirements.
