Abstract

This invention relates to a load management controller for a household electrical installation comprising a plurality of electrical sub-circuits. The electrical sub-circuits may each comprise a plurality of components, a single component or a part of a single component. A plurality of the electrical sub-circuits have electricity usage profiles containing rules determining the supply of electricity to the electrical sub-circuit. The load management controller has access to the electricity usage profiles of the electrical sub-circuits and controls the supply of electricity to the electrical sub-circuit in accordance with the electricity usage profile related to that electrical sub-circuit. The household electrical installation may comprise a rechargeable battery bank or supply that may be used to provide power to the household electrical installation.

Claims
