three-phase grid connection)
● In cascading scenarios, the inverters are required to connect to the management
system through a Smart Dongle.
● In the preceding networking, the SUN2000s are cascaded and support the grid-tied
point control function to achieve zero export.
● If the SUN2000s requires the grid-tied point control function, they need to be
connected to a smart power sensor.
● In the scenario of balanced three-phase grid connection, if the SUN2000s requires
the grid-tied point control function, they need to be connected to a three-phase
smart power sensor to control the total three-phase power.
● Only one LG battery is supported, and the LG battery must be connected to the
inverter equipped with the Smart Dongle.
