Embodiment Construction

[0025] In general, in one or more disclosed embodiments, a system includes several major components. In addition to a utility power source as the first or primary energy source, the system may include: a second power source, such as an uninterruptible power supply (UPS); associated switchgear and / or downstream interface circuitry associated with the second power source; an upstream AC switching device between the first and second power sources; and in some embodiments, an upstream generator and a control interface to delay or regulate operation of the generator. When the primary power source is absent or outside acceptable conditions for such power, the system may provide alternative and / or secondary energy sources for additional use without starting the generator. The system is believed to reduce installation costs by eliminating various components, particularly the grid-tie inverter, and in some embodiments by eliminating the MPPT controller. The system can also provide an ...

Abstract

The disclosure provides an efficient alternative energy uninterruptible power supply (UPS) system having a main first source of power coupled to an electrical load, comprising: a second source of power from stored energy coupled to the electrical load, the second source being adapted to supplement the first source and condition the power from the stored energy to predetermined conditions for the electrical load; an automatic transfer switch (ATS) coupled between the first source and the second source and adapted to control the first source coupling to the electrical load when the first sourcepower is noncompliant with predetermined conditions for the electrical load; and a source of alternative energy coupled downstream of the ATS to the second source, the electrical load, or a combination thereof, wherein the source of alternative energy comprises a source of direct current (DC) power.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of and priority to US Non-Provisional Application Serial No. 11 / 746,080, filed May 9, 2007, the contents of which are incorporated herein by reference for all purposes. [0003] Statement Regarding Research or Development Sponsored by the U.S. Federal Government [0004] No. [0005] Addendum to reference documents [0006] No. technical field [0007] The invention disclosed and taught herein relates generally to power systems, and more particularly to power systems using various energy sources. Background technique [0008] For decades, people have considered alternative sources of energy for supplemental power supplied by utilities to electrical loads. Such alternative energy sources include solar energy, geothermal energy, wind energy, hydro energy, fuel cells, biomass energy and gases derived therefrom, tidal energy, and the like. To generate the necessary voltage and / or cu...
