Abstract
Various implementations described herein are directed to systems and methods for managing a plurality of loads connected to a plurality of power sources using a switching apparatus. Apparatuses described herein may include multi-throw switches designed for fast and efficient switching of loads. Methods described herein may include selecting one or more loads from a group of loads to connect to one or more alternative power sources, and selecting one or more loads to connect to a main (e.g. utility) electrical grid.
Claims20
An electrical system comprising:
- a photovoltaic generator;
- a utility electrical grid;
- a plurality of switches configured to receive power from the photovoltaic generator and the utility electrical grid;
- a plurality of electrical loads, wherein each electrical load is connectable to the photovoltaic generator or the utility electrical grid;
- and
- a controller configured to connect or disconnect one or more of the plurality of electrical loads to and from the photovoltaic generator and the utility electrical grid,
- wherein the controller is configured to:
- determine that power generated by the photovoltaic generator exceeds a power consumption of one or more first electrical loads connected to the photovoltaic generator by a first value,
- determine that a power consumption of each electrical load of one or more second electrical loads connected to the utility electrical grid exceeds the first value, and
- store excess power generated by the photovoltaic generator to a storage device.
A method for operating an electrical system, the electrical system comprising a photovoltaic generator, a utility electrical grid, a plurality of switches, each of the plurality of switches configured to receive power from the photovoltaic generator and the utility electrical grid, and a plurality of electrical loads, each of the plurality of electrical loads connected to the photovoltaic generator or the utility electrical grid, the method comprising:
- monitoring electrical power output by the photovoltaic generator;
- monitoring electrical power consumed by one or more first electrical loads, of the plurality of electrical loads, connected to the photovoltaic generator, and
- responsive to determining that the electrical power output by the photovoltaic generator exceeds a power consumption of the one or more first electrical loads by a first value and a determination that a power consumption of each electrical load of one or more second electrical loads of the plurality of electrical loads, connected to the utility electrical grid of the electrical system exceeds the first value, storing excess power generated by the photovoltaic generator to a storage device.
