DESC:FIELD OF INVENTION
[0001] The present disclosure relates to the field of power backup systems and, more particularly relates to a power backup system capable of turning ‘ON/OFF’ an alternate source of power such as a generator.

BACKGROUND OF THE INVENTION
[0002] Batteries are extensively being used in transportation, military, aerospace and portable applications. Also, battery driven Electric Vehicles (EVs) are replacing conventional vehicles to reduce pollution and dependence on conventional energy resources.
[0003] Generally, in case of power outage from grid, the supply to all the critical loads is provided by a power backup system such as an inverter-battery system or a generator or any other alternate source of power. However, due to worldwide drive for moving away from fossil fuels as source of power, the use of diesel based generator is being discouraged in recent times.
[0004] The other alternate source of power such as systems utilizing solar power, wind power and other such renewable sources of power, are also not reliable due to lack of consistent supply of energy required for generating power from source of such power for example lack of consistent supply of solar radiations incident on solar PV panels.
[0005] Therefore, in order to overcome the above stated technical problems. Hybrid systems for supplying power have been developed, for example a system for clubbing PV panels and grid supply with an inverter having a solar charge controller with MPPT function. In such systems, in case of power outage from grid occurs, loads or electrical appliances are either powered by solar power generated by PV panels only, or power generated by PV panels and power supplied from battery bank, or in case of excess supply of power generated by PV panels in comparison with demand by loads, power generated by PV panels is supplied to power loads and charge batteries of battery bank.
[0006] However, in case no power is generated by PV panels and no power is being supplied by the grid, the loads are run on the battery bank. In such a scenario, in order to optimally use power from the battery bank only those loads are run which have been prioritized by an end user. The priority of loads to be run on battery bank depend on the type of place for which the battery bank is set, that is, whether such a property is a commercial property or a domestic property.
[0007] In case of commercial property, various types of electrical appliances having different voltage requirements may be required to be run by the battery bank. Therefore, in order to optimally use power from the battery bank to run multiple loads multiple outputs are required. However, as the functioning of the electrical appliances depends upon various parameters such as voltage, the supply of output must be pre-set.
[0008] Therefore, there is a requirement for a system that can set the parameters of each load, optimize power to be supplied to each load from the battery bank, set the priority of power supply from the battery bank, set a shutting off time of each load, alerts a user of no supply from the grid and other source of power, and allows all the functions to be remotely set by a user.
[0009] Such a system finds the disclosure in Indian Patent 292505, wherein a user settable power backup system with multiple outputs has been disclosed. The system comprises an inverter connected with multiple loads through its various outputs which are operated simultaneously or selectively. However, the system of this patent does not talk about automatic charging of batteries of battery bank, in case of depletion of charge of each battery below a pre-set level and in absence of supply from grid and alternate source of power.
[0010] Therefore, there is a need of a system that can automatically turn ON/OFF a generator that can supply power to multiple priority loads and simultaneously supply power to charge the batteries of the battery bank, when state of charge (SoC) of the battery bank goes below a pre-set level.

[0034] The present disclosure relates to a hybrid power backup system 100, as shown in Figure 1. The hybrid power backup system 100 comprises an automatic changeover control panel 40 configured to manage input power from multiple power sources, that is, a mains or grid power 10, a PV module 20 for solar power, a DG set or generator 30. The automatic changeover control panel 40 manages power input from these power sources for delivering continuous power supply at least to the loads defined as priority by automatically switching power source in case of non-availability of the other two power sources. For example, in case of power outage, solar power from PV module can be used to power the loads. However, in case of power outage and in-sufficient or non-availability of solar power from the PV module 20, automatic changeover control panel 40 automatically turns ON the DG set 30 ON to supply power to loads based on pre-defined priority.
[0035] The hybrid power back up system 40 further includes an inverter 50 that converts the input DC power into AC output power to power loads and charging a rechargeable battery 70. The battery 70 can be a Lithium ion or Lithium iron phosphate or Lead acid or the like. The inverter 50 is operatively connected to the automatic changeover control panel 40 to receive DC input from any single or combined source of power. The inverter 50 is further connected to a solar charge controller 60 with maximum power point tracking (MPPT), wherein the solar charge controller is configured to extract maximum solar power from PV module 20.
[0036] The inverter 50 is configured to provide backup power during a power outage, to a plurality of loads L1, L2, L3, L4 based on a pre-defined priority of load and a state of charge (SoC) of the rechargeable battery 70. The state of charge of the battery 70 indicates how much load and for how much time can it run the load. Further, the priority of load is decided based on factors such as the place required to be kept illuminated, the machine to be kept running in case of manufacturing unit, the voltage required and voltage available etc. The battery 70 stores power from solar 20 or mains 10 or DG set 30 and can provide power backup during non-availability of solar power, mains power.
[0037] In an embodiment, the inverter 50 further comprises a smart energy management module for optimizing energy consumption and prioritizing solar power usage.
[0038] The solar charge controller 60 configured to supply maximum solar power to the plurality of loads, for example L1, L2, L3, L4, and charging the battery 70 depending upon the State-of-charge (SoC) of the battery 90. The solar charge controller 60 is in remote communication (IoT) with a central server 90. The central server 90 is further in communication with a handheld device 200 and configured to store, retrieve, and display critical parameters over a display 80 related to each load, the battery, the solar charge controller, and a PV module; and a plurality of power switches for example P1, P2, P3, P4. Each load is connected to each power switch, and a power switch is tuned ON/OFF based on the pre-defined priority. In an embodiment, the display 80 configured to the central server 90 displays power consumption trends for each load.
[0039] In an embodiment, the display 80 further displays notifications and alerts about battery health, inverter status, and potential PV system issues.
[0040] In an embodiment, the central server 90 further manages user accounts and access controls for monitoring and controlling the system 100 from multiple devices.
[0041] In a preferred embodiment of the present disclosure, the automatic changeover control panel 100 turns ON a DG set 30 for continuous power supply to priority load during in-sufficient or non-availability of solar 20 and mains power 10.
[0042] In an embodiment, the automatic changeover control panel 40 is further configured to supply power from the DG set 30 to the battery 70 based on breach of a pre-defined threshold of the SoC of the battery 70. The pre-defined threshold of SoC can be for example 20% of battery charge left.
[0043] In an embodiment, the automatic changeover control panel 40 further includes a built-in timer to automatically turn ON/OFF the generator.
[0044] In an embodiment of the present disclosure, a user is able to set input priorities and parameters for the plurality of switches P1, P2, P3 and P4 to be operated. The solar charge controller 60 is further configured to send a notification to alert the user of depletion of charge of the battery 90 below a pre-set level, say 50%, and the changeover control panel 40 automatically turns ON a generator 30, in absence of a command from the hand held device 200 of the user.
[0045] In an embodiment, the handheld device 200 is selected from the group comprising a multimedia device, a smartphone, a tablet, and a smartwatch. The user of the handheld device 200 can access information available over the display 80 of the central server 90, and accordingly manipulate or customize the priority of power, power switches, loads etc.
[0046] In an embodiment, the central server 90 is in wireless communication with an application running on a memory of the handheld device 200.
[0047] In an embodiment, the input priorities include shutting OFF a load based on a load battery voltage, state of charge and time period.
[0048] In an embodiment, the input parameters are the parameters of load/appliance at each output.
[0049] In an embodiment, the user can change the parameters from a remote location. During the power outage, lack of supply from PV panels 20, the power back up system can optionally supply power from the battery 70 to the connected load(s) as per priority, and at the predefined set level, and will also send a first alert notification to the hand held device 200 of the user. The alert notification may be, but not limited to, e-mail, SMS, MMS, and the like.
[0050] In another embodiment, upon depletion charge of each battery of the battery bank beyond a pre-defined level or a level set by the user, the automatic changeover control panel 40 will cut off supply to the connected load(s) and another notification to the hand held device 200 of the user will be sent from the hybrid power back up system 100. In case no command is received from the user in a pre-set time limit set in the built-in timer, the changeover control panel 40 will automatically turn ON the generator 30 to power the connected load(s) as per priority and at the predefined set level, and will also send a second alert notification to the hand held device 200 of the user regarding power supply from DG set 30.
[0051] In an embodiment, upon restoration of grid power 10 or power from OV module 20 or full charge of the battery 70, the automatic changeover control panel will turn OFF the generator 30 and will send a third alert notification to the hand held device 200 of the user.
[0052] Numerous modifications and adaptations of the hybrid power backup system 100 of the present invention will be apparent to those skilled in the art, and thus it is intended by the appended claims to cover all such modifications and adaptations which fall within the true spirit and scope of this invention.
