3. Lithium battery communication configuration
ADD Switch: There are 4 ADD switches are to define different baud rate and battery group
address. If switch position is turned to bottom for “OFF” position, it means “0”. If switch
position is turned to upper for “ON” position, it means “1”.
⚫Dip 1 must be set to "ON" (baud rate 9600).
⚫Dip 2, 3 and 4 are used to set up the battery group address. Further information can be
found in the manual for the Pylontech US 2000 lithium battery.
Note:
•Only the AX M1 4000/5000-48 and AX K1 4000/5000-48 inverter with the firmware
version xx.40 or higher can communicate with Pylontech batteries via the AX Li Com-
Box.
•If there is more than one battery group, the HV device (hub) is also required. In this
case the AX Li COM Box must be connected to the Hub instead of the batterie
(Pylontech manual, page 37).
