temperature will be sent through to the inverter. Please refer to figure 6 for parameters
displayed on a SunSynk inverter with the AZBAT48100 batteries.
Figure 6: Inverter charge and discharge information received from the battery BMS.
The figure on the left displays the charge and discharge information for an installation using 1 battery.
The figure on the right displays the information when 2 batteries are connected in parallel. These
values should match that as referenced in Table 5 for the number of batteries connected in parallel.
Parallel connection
When using more than one battery, the first battery will be the MASTER and the other batteries will
be SLAVES. The CANBUS connection from the inverter will be connected to the MASTER battery.
