NOTICE
：
In a parallel battery system, we strongly advise not to switch off individual sub batteries when the system
is running either in Charge or Discharge Mode as this process might affect the communication between
modules and inverter.
Switching off an individual sub battery in a parallel system is possible in an adverse situation, but only as a last resort and
prior switching off the solar inverter
