(1) When the inverter is connected to a third-party monitoring device, please confirm which communication

interface is used, and whether it will cause loss of certain functions of the inverter.
(2) When RS485 (A1, B1) is used for parallel connection in the master inverter, the LG Chem battery (that uses

RS485 for communication) cannot be used with the master inverter. It can still be used with the slave inverter.
Take Smart Energy Meter connection as an example.
