Size and Capacity of Battery Storage Systems

Our Answer

A battery storage system has two critical sizing parameters, one is the power of the system. This is the amount of power the system can charge and discharge at measured in KW or AMPS.
The second critical parameter is the battery storage capacity, this is a measure of the amount of energy that can be stored in KWhours or AmpHours. This value can be difficult to compare as different battery technologies and different manufacturers use different specification measurements!
