Clusters, up to 15 modules with current above 300A.
When it is required to have an installation with more than 300A charging and Discharging current, ( but still within
the Battery maximum allowed current managed by the BMS of by the LV HUB) it Is necessary to arrange the power
connection from any individual battery to a common bus bar.
If required by your National or Local electrical laws, a breaker could be necessary in between the battery and the
bus bar and in between the inverter poles and the bus bar.
The maximum allowed charging current is controlled by the BMS according with the number of modules connected
If more than one cluster it is present in your configuration, you need to use the LVHUB ( CAN COMBINER ) and
composing the cluster power connection as per the below diagram.
Bus Bar as cascade connection are limited to 300A above such current is necessary to follow the below connection
diagram
Example of 8 modules connected individually to a common bus bar for charging /Discharging current
greater than 300A
This concept can be repeated up to 15 modules when the inverter is greater than 300A
Above 300A it is mandatory to individually connected each single module from the LV connection terminal to
a common bur by using a cable properly sized.
