     FIELD 
     The present disclosure relates to methods and systems for integrating energy control systems with electrical systems. In particular, embodiments relate to methods and systems for integrating energy control systems with electrical systems to improve load management and control of photovoltaic (PV) power supply. 
     BACKGROUND 
     Residential electrical systems vary from home to home, where power in each home may be distributed from a utility feed to a plurality of electrical loads in myriad ways. For example, some residential homes feature a single panel for servicing all electrical loads of the residential system, whereas other systems use multiple service panels, including a main service panel and one or more subpanels directed to a subset of electrical loads. Moreover, the utility service sizes and load breaker sizes of residential electrical systems differ according to the size and the geographic location of the home. Residential electrical systems may also differ by having alternative energy sources, for example, photovoltaic power generation systems and/or energy storage systems that provide power to the loads or back to the grid. 
     Thus, due to these countless number of differences, integrating a stand-alone energy control system with various types of electrical systems can be challenging.

     The features and advantages of the embodiments will become more apparent from the detail description set forth below when taken in conjunction with the drawings. A person of ordinary skill in the art will recognize that the drawings may use different reference numbers for identical, functionally similar, and/or structurally similar elements, and that different reference numbers do not necessarily indicate distinct embodiments or elements. Likewise, a person of ordinary skill in the art will recognize that functionalities described with respect to one element are equally applicable to functionally similar, and/or structurally similar elements. 
     DETAILED DESCRIPTION 
     Embodiments of the present disclosure are described in detail with reference to embodiments thereof as illustrated in the accompanying drawings. References to “one embodiment,” “an embodiment,” “some embodiments,” “certain embodiments,” etc., indicate that the embodiment described can include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described. 
     The term “about” or “substantially” or “approximately” as used herein refer to a considerable degree or extent. When used in conjunction with, for example, an event, circumstance, characteristic, or property, the term “about” or “substantially” or “approximately” can indicate a value of a given quantity that varies within, for example, 1-15% of the value (e.g., ±1%, ±2%, ±5%, ±10%, or ±15% of the value), such as accounting for typical tolerance levels or variability of the embodiments described herein. 
     The terms “upstream” and “downstream” as used herein refer to the location of a component of the electrical system with respect to the direction of current or power supply. For example, a first component is located “upstream” of a second component when current is being supplied from the first component to the second component, and a first component is located “downstream” of a second component when current is being supplied from the second component to the first component. 
     The term “main circuit breaker” as used herein refers to a circuit breaker configured to disrupt power supply from the utility feed to all or substantially all the plurality of loads associated with the electrical system. 
     The following examples are illustrative, but not limiting, of the present embodiments. Other suitable modifications and adaptations of the variety of conditions and parameters normally encountered in the field, and which would be apparent to those skilled in the art, are within the spirit and scope of the disclosure. 
     For a residential electrical system, power can be distributed from a utility feed to a plurality of loads using various configurations. For example, a residential electrical system can include a service breaker panel integrated with a utility meter or the service breaker panel can be separated from the utility meter by being disposed inside the residential building. Rather than relying on a single service panel to serve all the home&#39;s electrical loads, some residential electrical systems can use multiples panels, such as a combination of a main service panel connected directly to utility feed and one or more downstream subpanels for serving one or more subsets of loads. The size of the utility feed can vary according to the energy demands of the home. For example, larger homes with multiple buildings, such as an auxiliary garage or a pool house, can require a larger utility service size (e.g., 400 A) compared to the utility service size (e.g., 200 A) for smaller residential buildings. Some residential electrical systems can also include a residential power supply system, such as a photovoltaic system or an energy storage system, that supplements the power feed received from the grid. 
     Due to these countless number of differences, integrating a stand-alone energy control system with various types of electrical systems can be challenging. For example, integrating a control system with a residential system having a backup photovoltaic system may not be able to serve all loads of the home if some of the home&#39;s load breaker sizes are too large (e.g., load breakers greater than 40 A). Consequently, some conventional energy control systems use multiple control panels, one panel serving small loads backed up by the photovoltaic system and another panel serving larger loads only powered by the grid. Moreover, some residential electrical systems having both an energy storage system and a photovoltaic system typically use multiple control panels such that one control panel is designated for metering feed from the photovoltaic system, whereas another panel is designated for metering feed from the energy storage system. 
     Thus, there is a need for procedures and systems that allow a control system to be integrated with an existing electrical system that allows the control system to use a single panel to serve various types of breaker sizes, load types, service panel types, circuit breaker locations, and/or residential power supply systems. 
     According to embodiments described herein, the methods of the present disclosure for integrating an energy control system with an existing electrical system can overcome one or more of these deficiencies, for example, by providing a method for integrating an energy control system with an electrical system having a utility meter connected to a utility grid, a photovoltaic (PV) system, an energy storage system, and/or a plurality of electrical loads. In some embodiments, the method includes a step of determining a site condition of the electrical system. In some embodiments, the method includes a step of determining a type of backup configuration for the electrical system based on the determined site condition. In some embodiments, the method includes a step of determining a location of at least one of a main circuit breaker, the PV system, a subpanel, and a site current transformer with respect to the energy control system based on the determined site condition and the determined type of backup configuration. 
     In some embodiments, the method includes a step of locating the energy control system downstream of the utility meter and upstream of at least one of the plurality of electrical loads. In some embodiments, the method includes a step of connecting at least one of the main circuit breaker, the PV system, the subpanel, and the site current transformer to the energy control system based on the determined locations. In some embodiments, the site condition include at least one of a type of service panel electrically connected to utility meter, a size of utility service supplied by the utility grid, a size of a largest load breaker associated with the plurality of loads, and a storage capacity of the energy storage system. 
     By locating various components of the electrical system based on the determined site conditions and backup configurations, the energy control system can be integrated with the electrical system in a manner that improves load management and efficient control of photovoltaic power supply.

No. 17/324,715, filed May 19, 2021, titled “PHOTOVOLTAIC DISCONNECT DEVICE FOR STORAGE INTEGRATION,” the entirety of which is incorporated herein by reference. For example, in some embodiments, a PV disconnect device can be configured to monitor electronic data, such as AC voltage, current, and frequency measurements across the feed circuit of backup PV system  260  and/or non-backup PV system  290 .

     In some embodiments, electrical components (e.g., interconnections, switches, relays, AC bus) of energy control system  100  can be integrated into a single housing. For example, as shown in  FIGS.  1 A-B , in some embodiments, energy control system  100  can include a housing  102 . In some embodiments, housing  102  can be comprised of plastic, metal, or a combination of plastic and metal. In some embodiments, energy control system  100  can include a cover  104  enclosing one or more components (e.g., a PV monitoring system) disposed in housing  102  of energy control system  100 . In some embodiments, cover  104  can be comprised of plastic, metal, or a combination of plastic and metal. In some embodiments, cover  104  can be rotatably and/or removably connected to housing  102 . In some embodiments, energy control system  100  can include a door  106  that is configured to be opened and closed to access components (e.g., switches) mounted within housing  102 , for example on a mounting plate. 
     In some embodiments, energy control system  100  can be integrated into and operatively compatible with multiple types of residential electrical systems that include various types of PV systems, energy storage systems, electrical loads, and/or utility grid interconnections. The most efficient procedure for integrating energy control system  100  with a particular residential electrical system can vary compared to other residential electrical systems based on one or more site conditions associated with the particular residential electrical system. 
       FIG.  3    shows an example block diagram illustrating aspects of a method  300  for integrating energy control system  100  into an existing electrical system, such as, for example, a residential electrical system (e.g., electrical system  200 ). 
     In some embodiments, method  300  can include a step  310  of determining one or more site conditions of the existing electrical system. In some embodiments, the one or more site conditions indicate the state of the existing electrical system. In some embodiments, the one or more site conditions include the type of main service panel connected to the utility grid, such as, for example, main service panels integrated with utility meters and main service panels spatially separated from utility meters. In some embodiments, the one or more site conditions can include the size of utility service, such as for example, 100 A, 200 A, and 400 A service panels. In some embodiments, the one or more site conditions can include the size of largest load breakers in the electrical system, such as for example, 40 A circuit breakers, 50 A circuit breakers, and 60 A circuit breakers. In some embodiments, the one or more site conditions can include the type of electrical loads, such as, for example, distinguishing between critical electrical loads (e.g., lighting, router) and non-critical electrical loads (e.g., air conditioner, oven). In some embodiments, the one or more site conditions can include the state of the existing electrical infrastructure, such as, for example, the age of the service panels. In some embodiments, the one or more site conditions can include the capacity of the energy storage system (e.g., storage system  250 ) linked to the service panel, such as, for example, the number of storage batteries and storage inverters. 
     In some embodiments, method  300  can include a step  320  of determining the backup configuration for the electrical system based on the one or more site conditions. In some embodiments, step  320  can include determining a partial home backup configuration, in which the plurality of electrical loads associated with the electrical system are split into backup loads (e.g., backup loads  272 ) and non-backup loads (e.g., non-backup loads  274 ). In some embodiments, step  320  can include determining a whole home backup configuration, in which all or substantially all the electrical loads associated with the electrical system are connected to the backup power bus  112  of energy control system  100 . 
     In some embodiments, the one or more site conditions of the existing electrical system can only permit a partial home backup configuration because one or more of the electrical loads need to be electrically coupled to the non-backup power bus  110  via non-backup load interconnection  174 . For example, in some embodiments, if the service panel type of the electrical system includes a main service panel integrated with the utility meter, energy control system  100  is disposed downstream of the main service panel, where large electrical loads coupled to the main service panel are migrated to the non-backup power bus  110  via non-backup load interconnection  174 . In some embodiments, any large load break size above 40 A is electrically coupled to non-backup power bus  110  via non-backup load interconnection  174 . In some embodiments, if the electrical system includes a PV system split into a backup PV system and a non-backup PV system, then non-backup PV system is electrically coupled to the non-backup power bus  110  of energy control system  100 . 
     In some embodiments, after determining the site conditions of the electrical system (e.g., step  310 ) and determining the backup configuration of the electrical system (e.g., step  320 ), method  300  can include a step  325  of determining a location of an electrical component with respect to energy control system  100  based on the one or more site conditions and/or the selected backup configuration for the electrical systems. As shown in  FIG.  3   , in some embodiments, step  325  can include one or more steps (e.g., steps  330 ,  340 ,  350 , and/or  360 ) for determining the location of electrical components of the electrical system (e.g., electrical system  200 ) with respect to energy control system  100  based on the one or more site conditions and/or the selected backup configuration for the electrical systems. By determining the location of the electrical components of the existing electrical system with respect to energy control system  100  based on the one or more site conditions and/or the selected backup configuration for the electrical systems, energy control system  100  can be integrated with an existing electrical system in a manner most suitable for the specific site conditions, such as regulating power supply from backup PV system  260  and energy storage system  250  more efficiently or ensuring proper load management. 
     In some embodiments, method  300  can include a step  330  of determining the location of main circuit breaker with respect to energy control system  100  based on the one or more site conditions and/or the selected backup configuration for the electrical system. In some embodiments, the main circuit breaker can be configured to disrupt electrical connection between utility grid (e.g., utility grid  280 ) and the rest of the components (e.g., the plurality of electrical loads  170 , the main service panel) of the electrical system in response to power surges that exceed threshold power limits. In some embodiments, step  330  can include a sub-step  332  of locating the main circuit breaker within the housing  102  of energy control system  100 , such as, for example, when energy control system  100  can completely replace the existing main service panel and/or be installed in a new home that does not include an existing main service panel. In some embodiments, step  330  can include a sub-step  334  of locating the main circuit breaker outside and upstream of the housing  102  of energy control system  100 , such as, for example, when energy control system  100  is disposed downstream of the existing main service panel. 
     In some embodiments, method  300  can include a step  340  of determining the location of the PV systems with respect to energy control system  100  based on the one or more site conditions and/or the selected backup configuration for the electrical system. In some embodiments, step  340  can include a sub-step  342  of electrically connecting a backup PV system to backup PV interconnection  160 . In some embodiments, step  340  can include a sub-step  344  of electrically connecting a non-backup PV system to a non-backup PV interconnection  190 . 
     In some embodiments, method  300  can include a step  350  of determining the location of the subpanels of the electrical system with respect to energy control system  100  based on the one or more site conditions and/or the selected backup configuration for the electrical system. In some embodiments, a subpanel can be located downstream of a main service panel and be configured to control power distribution to one or more subsets of electrical loads, In some embodiments, the electrical system can not include any subpanels for servicing electrical loads (e.g., no panels  356  shown in  FIG.  3   ). In some embodiments, the electrical system can include a sub-step  352  of electrically connecting service panels to the grid interconnection  180  on the non-backup side of energy control system  100 , such as, for example, when the service size of utility grid is 400 A split into two 200 A feeders. In some embodiments, the electrical system can include a sub-step  354  of electrically connecting service panels to the backup power bus  112  via backup load interconnection  172 , such as, for example, when the electrical system includes a downstream subpanel electrically coupled to all the electrical loads of the residential home. 
     In some embodiments, method  300  can include a step  360  of determining the location of the site current transformer (site CT) with respect to the energy control system  100  based on the one or more site conditions and/or the selected backup configuration for the electrical system. In some embodiments, site CT is configured to monitor energy consumption by the plurality of electrical loads. In some embodiments, step  360  can include a sub-step  362  of locating site CT within housing  102  of energy control system  100 , such as, for example, when all electrical loads of the electrical system are connected to energy control system  100 . In some embodiments, step  360  can include a sub-step  364  of locating site CT outside the housing  102  of the energy control system  100 , such as, for example, when one or more electrical loads are not connected to the energy control system  100 . 
     In some embodiments, method  300  can include a step of determining the number and location of one or more PV disconnect devices with respect to energy control system  100  based on the one or more site conditions and/or the selected backup configuration for the electrical system. For example, in some embodiments, for example, under a partial backup configuration, electrical system can include a first PV disconnect device electrically coupled to the feed circuit of a backup PV system and a second PV disconnect device electrically coupled to the feed circuit of a non-backup PV system. In some embodiments, for example, under a whole home backup configuration, electrical system can include a PV disconnect device electrically coupled to the feed circuit of a backup PV system.

     Integrating multiple energy control systems  100 A,  100 B with an electrical system that features multiple  200  A feed circuits, such as, for example, electrical system  2200 , provides significant advantages over electrical systems that include only a single energy control system. For example, integrating multiple energy control systems with an electrical system provides that backup power is distributed to all subpanels (e.g., subpanel  2208 , subpanel  2210 ) of the electrical system, including subpanels that are electrically coupled to large electrical loads (e.g., 50 A rating or greater). Additionally, integrating multiple energy control systems  100 A,  100 B with an electrical system allows the electrical system to implement multiple microgrid systems (e.g., first and second microgrid systems  2220 ,  2230 ), in which each microgrid system can operate independent of the other microgrid system while still being synced with the grid. Furthermore, integrating multiple energy control systems  100 A,  100 B with an electrical system allows a user to expand the storage capacity and PV power output rating of the electrical system, thereby minimizing the use of grid power supply. Also, using a computing device to sync the electronic data from each of the microgrid systems prevents conflicts with managing site consumption, PV power output, and/or energy storage capacity of the entire electrical system.
