● If multiple SUN2000s need to communicate with one another and are
connected to a PC over the SmartLogger1000, a maximum of three daisy
chains can be configured.
● If multiple SUN2000s need to communicate with one another and are
connected to a PC over the SmartLogger2000, a maximum of six daisy chains
can be configured.
● To ensure the system response speed, it is recommended that the number of

Smart Dongle scenario
NO TE
● If the SUN2000 is networked using the SDongleA-03 (4G, Smart Dongle for short), it
cannot be connected to the SmartLogger.
● If the SUN2000-60KTL-M0 version is SUN2000 V300R001C00SPC116 or later, the
RS485_2 port can connect to the DTSU666-H smart power sensor. Due to the power
measurement limit of the DTSU666-H, the current should not exceed 250 A.
● If the Smart Dongle version is SDongle V100R001C00SPC116 or later, the
SUN2000-60KTL-M0 can connect to the DTSU666-H smart power sensor to implement
power scheduling. This document describes only the networking diagrams. For details
