DIP Switch Description
When the batteries are connected in parallel, the master communicates with the
slaves through the CAN interface. LV-Link summarizes the information of the entire
battery system and communicates with the inverter through CAN or 485.
If the master is the LV-Link with DIP switch:
1. The communication cable from LV-Link CAN IN to the inverter comm port
should be the correct one.
