3.3 Minimum Battery System Capacity
Battery charge and discharge rates are managed automatically by the Discover
Lithium Battery and SMA Sunny Island device. Using large solar arrays with battery
banks that are too small can exceed the operating limits of the battery to charge
and possibly lead to the BMS triggering over-current protection. Curtail the charging
below the operational limit of the installed batteries, or the battery capacity must
accept the maximum charge current of the system. Calculate this value by adding
the charge capacities of all inverter-chargers and solar charge controllers in the
system. Additionally, battery peak capacity must support the surge requirements
demanded by the load attached to the inverter. Match all inverter peak power values
with the sum of all battery peak battery current values.
