1. A residential energy installation comprising:
- Storage batteries for storing energy;
battery state monitoring for monitoring the charging and state of charge of said storage batteries and for generating a corresponding charging status information output;
DC to AC conversion for converting DC power input from said storage batteries to residential power at an AC power output, anda Smart Load Center for distributing power through appropriate circuit breakers to a number of branch circuits, said Smart Load Center having a first AC power input from said AC power output from said DC to AC conversion and a second AC power input from an electric utility grid, the power source being selectable for at least one of said branch circuits to be either said first power input or said second power input in dependence on said information output from said battery state monitoring.

Abstract
An improved residential electrical energy system is described based on the use of a smart load center or power distribution panel configured to select the use of utility power or power derived from storage batteries independently for each of a number of load circuits based on availability of utility power and battery charge state information.
