(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.
