3.6 Minimum Specifications for Discover Battery Module Systems
Install ELEMENT ESS battery modules in parallel in a battery bank configuration to
increase system capacity. Overall battery module system capacity must be correctly
sized to meet the requirements of the load and account for:
• Total Continuous Charge Current
• Total Peak Current
• Total Continuous Discharge Current
The total charging capacity of all charging sources in the system should not exceed
the Continuous Charge Current operating limit of all the battery modules in the
system. Exceeding this limit will cause the BMS in battery modules to trigger over-
current protection and disconnect. The charging system’s maximum Continuous
Charge Current must either be below the operating limit of installed battery
modules or curtailed.
The sum of all the Peak Current values for the attached loads must be less than the
Peak Current value of the battery module system, including inrush current values for
any motors and surge values for any inverters.
The sum of all the Continuous Discharge Current values for the attached loads must
be less than the Continuous Discharge Current value of the battery module system.
For ELEMENT ESS battery modules installed in parallel in a battery bank
configuration, the sum of all battery module capacities provides the overall capacity
value for the battery module system. Table 3-7 provides DC capacity values for
sample Discover battery module systems.
NOTICE
• Exceeding the Peak Current, Continuous Discharge, or Continuous Charge values
of the battery modules in the system will lead to either tripping the battery module
Breaker or triggering the battery module BMS over-current protection, resulting in
disconnection of all battery modules in the system.
• Disconnection will result in a voltage spike (Load Dump), which may damage any
component electrically attached to the battery module system.
NOTE
The maximum number of battery modules installed in a parallel configuration is 24.
