Electrical System for Providing Electricity

A system comprising one or more processors and a non-transitory computer readable storage media embodying software coupled to the one or more processors, the one or more processors operable to execute the software to:

• determine whether an amount of electricity used by an end user exceeds an amount of electricity a first electrical network is capable of providing to the end user, wherein the first electrical network comprises a first conductive path electrically coupling the first electrical network to electrical wiring of the end user, and the electrical wiring of the end user is also electrically coupled to a second conductive path of a public-utility electrical network;
• in response to a determination that the amount of electricity used by the end user does not exceed the amount of electricity the first electrical network is capable of providing to the end user, draw electricity to the end user only from first electrical network;
• and
• in response to a determination that the amount of electricity used by the end user exceeds the amount of electricity the first electrical network is capable of providing to the end user, draw electricity to the end user from the first electrical network and from the public utility electrical network,
• wherein the switch at all times electrically isolates the first electrical network from the public utility electrical network.

A method comprising:

• determining, in association with a switch coupled between a first conductive path of a first electrical network and electrical wiring of an end user and between a second conductive path of a public utility electrical network and the electrical wiring of the end user, whether an amount of electricity used by the end user exceeds an amount of electricity the first electrical network is capable of providing to the end user;
• in response to a determination that the amount of electricity used by the end user does not exceed the amount of electricity the first electrical network is capable of providing to the end user, drawing, through the switch, electricity to the end user only from first electrical network;
• and
• in response to a determination that the amount of electricity used by the end user exceeds the amount of electricity the first electrical network is capable of providing to the end user, drawing, through the switch, electricity to the end user from the first electrical network and from the public utility electrical network,
• wherein the switch at all times electrically isolates the first electrical network from the public utility electrical network.
