PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. The Smart Energy Storage System with external data input from the external
current transformer,
with the data's magnitude and phase proportional to the sum of the current
used by the customer
added to that used by the Smart Electrical Energy Storage System, which is
then used by the Smart
Electrical Energy Storage System's System Controller in combination with the
line voltage to
calculate the electrical power consumed the value of which is then used by the
System Controller to
determine whether to change the state of charge of the electrical energy
storage device, which when
changed alters the apparent power the customer uses from the electric utility.
2. The Smart Energy Storage System with external data input from the external
current transformer
according to claim 1 including the feature that allows customers to alter the

10. The Smart Energy Storage System with external data input from the external
current transformer
according to claim 1 including the amount of electric power generated by the
external electric power
source being measured and recorded with the recorded information made
available by the system
controller to be read from the communications interface.
11. The Smart Energy Storage System with external data input from the external
current transformer
