3.3 Minimum Battery System Capacity
Battery charge and discharge rates are managed automatically by the Discover
Lithium Battery and Sol-Ark 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. Battery capacity must
accept the maximum charge current of the system, or charging must be curtailed
below the operating limit of the installed batteries. Derive this value by adding
together 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.
Inverter Peak = (Inverter Surge Value) / (Inverter Efficiency) / (48V: Low Battery Cut-Off)
