During power outages, it is useful to have a backup power source to provide electricity. Current methods of providing a backup power source involve connecting a backup power source directly to an electrical panel bypassing the electrical meter. However, the current National Electric Code (NEC) for transfer switch connection requires customers installing a separate electric panel to dedicate certain branch circuits to be connected to the backup generator based on the rating of the backup generator or backup power. For customers to be compliant, they must install a new transfer switch and panel as the “correct” installation in
Therefore, there is a need for a system that enables a user to connect one or more backup power sources directly to an electrical meter and/or control one or more functions of the one or more backup power sources using the electrical meter.
In some embodiments, the Backup Power Transfer Meter (BPTM) system (hereafter, the “system”) is an economical approach to simplify the NEC interconnection requirement. In some embodiments, the system allows the customers to temporarily power their home using a backup power source (e.g., combustion generator, battery, photovoltaic, electric vehicle, etc.) when utility power is unavailable or off grid. In some embodiments, the system includes an auto-transfer switch that senses and switches to an alternate electrical power source (i.e., backup power source) when utility electrical power is interrupted. In some embodiments, the system automatically switches back to utility power when it becomes available. In some embodiments, they system is installed at the customer's existing conventional electric panel. In some embodiments, the system is configured to sense and transfer one or more loads in a customer's home load to the backup power source when the utility power is off grid and vice versa.

The transformed data can be saved to storage generally, or in particular formats that enable the construction or depiction of a physical and tangible object. In some embodiments, the manipulation can be performed by a processor. In such an example, the processor thus transforms the data from one thing to another. Still further, some embodiments include methods can be processed by one or more machines or processors that can be connected over a network. Each machine can transform data from one state or thing to another, and can also process data, save data to storage, transmit data over a network, display the result, or communicate the result to another machine.
