However, Ashman disclose the system receives a designation of one or more ports as a critical port; (Ashman: “In some embodiments, a first step includes control circuitry 4311 causing user-defined circuits (e.g., one or more of branch circuits 4330) to be automatically disconnected in different stages to reduce power consumption) wherein the system is operable to detect an amount of power available from each of the one or more battery ports and the one or more generator ports in real time; (Ashman: see the circuit breakers 504 with meters 505 for measuring power and energy in real time from each branch including the solar system 514 and battery system 519 as illustrated in figures 7, 9 and as described in paragraphs 0112, 0114, 0116; “a sensor system configured to measure one or more electrical parameters corresponding to the plurality of branch circuits” paragraph 0006) wherein the system is operable to detect an amount of power demand from each of the plurality of load ports in real time; (Ashman: see the circuit breakers 504 with meters 505 for measuring power and energy in real time from each branch including the loads 506 as illustrated in figures 7, 9 and as described in paragraphs 0112, 0114, 0116; “The system may be configured to monitor and control various electrical loads 506.” Paragraph 0112; “In some embodiments, current sensor 200 is configured to sense one or more voltages, as well as current, and may be configured to calculate, for example, power measurements associated with branch circuits or other loads.” Paragraph 0109; “For example, the temporal information may include an on-off time schedule for each breaker (e.g., which may be based on the measured load in that branch circuit), duration information (e.g., how long a branch circuit will be left on), any other suitable temporal information, an estimated time remaining (e.g., during operation on battery power, or until a pre-scheduled disconnect), or any combination thereof.” Paragraph 0153) and wherein the controller automatically reduces or cuts power to one or more of the plurality of load ports based on the amount of power available from each of the one or more battery ports and the one or more generator ports, the amount of power demand from each of the plurality of load ports, and the designation of the critical port (Ashman: “In some embodiments, a first step includes control circuitry 4311 causing user-defined circuits (e.g., one or more of branch circuits 4330) to be automatically disconnected in different stages to reduce power consumption. In some embodiments, a first set of loads (e.g., less critical loads, or highly draining loads) are disconnected as soon as the system goes off-grid (e.g., AC bus 4320 is disconnected from a power grid).
Therefore, it would have been obvious to one ordinary skill in the art before the effective filing date of the claimed invention to modify Heidenreich by adding plurality of branch circuits as part of its configuration as taught by Ashman, in order to measure one or more electrical parameters using voltage sensor coupled to buses electrical loads.
Regarding claim 2, Heidenreich disclose the system determines insufficient power is available from the one or more battery ports and/or the one or more generator ports, the controller is operable to automatically utilize the grid bypass ; (Heidenreich: see the utility 22 connected to the transformer 30 via the winding 42 as illustrated in figure 1; see the utility 322 connected to the transformer 330 via the winding 342 as illustrated in figure 5; “The example UPS system 20 is adapted to obtain power from and supply power to a utility 22 and also to provide power to a primary load 24.

For example, the temporal information may include an on-off time schedule for each breaker (e.g., which may be based on the measured load in that branch circuit), duration information (e.g., how long a branch circuit will be left on), any other suitable temporal information, an estimated time remaining (e.g., during operation on battery power, or until a pre-scheduled disconnect), or any combination thereof.” Paragraph 0153).
Therefore, it would have been obvious to one ordinary skill in the art before the effective filing date of the claimed invention to modify Heidenreich by adding on-off time schedule for each breaker as part of its configuration as taught by Ashman, in order to control measured currents from branch circuit to manage electrical loads.

In some embodiments, a first set of loads (e.g., less critical loads, or highly draining loads) are disconnected as soon as the system goes off-grid (e.g., AC bus 4320 is disconnected from a power grid). Accordingly, the other stages are then connected or disconnected as soon as pre-defined battery state of charge levels are reached (e.g., by a battery system of devices 4380 coupled to AC bus 4320 via an AC-DC converter of devices 4380).” Paragraph 0217; “For example, a user may specify which loads should be shed in which order or priority during an event. In some embodiments, identifying the indicator includes identifying the event, and determining the one or more limits is based at least in part on the event. For example, the system may detect an interruption in the AC grid, and accordingly enter a limiting mode.” Paragraph 0010; “In some embodiments, the system executes logic that generates and/or uses forecasts of branch circuit loads, appliance loads, measurements of branch circuit loads (e.g., based on signals from a sensor board), or a combination thereof to dynamically disconnect or reconnect branch circuits to the distributed energy resource, send electrical signals to appliances on branch circuits enabling or disabling them in order to optimize energy consumption, maintain the islanded electrical system power consumption at a low enough level to be supplied by the distributed energy resource, or a combination thereof. In some embodiments, the system includes an energy reservoir device such as, for example, one or more capacitors or batteries, capable of maintaining logic power and switching device actuation power in the period after the utility grid point of connection circuit switching device has disconnected the electrical system from the utility grid, and before the distributed energy resource begins to supply power to the islanded electrical system, in order to facilitate actuation of point of connection and branch circuit switching devices to effect the aforementioned functions.” Paragraph 0170; “In some embodiments, control system 4310 (control circuitry 4311 thereof) automatically sheds load(s) to prevent overload, ensure continuity of power overnight or through cloudy days, or both. In some embodiments, the operating criteria may include partition of loads indicating which can be shed or in what order loads are shed (e.g., “nice to haves” are shed before “must haves”).” Paragraph 0220).

However, Ashman disclose the plurality of loads includes at least one electric vehicle charging station (Ashman: para; 0214, a battery system, an electric vehicle charging station, a solar panel system, a DC-DC converter, an AC-DC converter, and AC-AC converter, a transformer, any other suitable device coupled to an AC bus or DC bus).
Therefore, it would have been obvious to one ordinary skill in the art before the effective filing date of the claimed invention to modify Heidenreich by adding vehicle charging station as part of its configuration as taught by Ashman, in order to charge vehicles by using solar panel system in different location.
Regarding claim 20, Heidenreich disclose the one or more power generators include one or more solar cells (para; 0044, lines 3-6, alternative energy source 350 is an array of solar panels, and the charge controller 352 generates a charge signal appropriate for charging the battery array 334 based on the electrical output of the solar panels).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Yim US 2004/0017110 Al- The present invention provides an uninterruptible switching power supply device and a method for uninterruptible switching from AC input power to DC power, in which a high voltage circuit connected with the primary winding of the main transformer and a lower voltage circuit connected with a tap from the secondary are controlled by a PWM to operate synchronically. When the AC input is normal, the AC input power is transformed the main transformer to power a load. When the voltage of the AC input is lower than the predetermined value, the battery begins to discharge for compensating the power of the AC input. When the AC input is interrupted, the discharge of battery is transformed by the transformer in a self-coupling mode to power the load. The voltage transformation efficiency is improved with the device and method of the invention.
