FIELD OF INVENTION
The present invention relates to a power backup system for maintenance and configuration of power backup system. The present invention in particular relates to a power backup system for the dealer/ authorized user wherein the dealer/ authorized user can set various parameters of the power backup system.
PRIOR ART
Very recently, inverters are considerably popularized, and these inverters are used in various fields. As a result, user-friendly supports are required for wide ranges for maintenance of these inverters.
On the other hand, in such a case, in accordance with the conventional support system, at a time instant when operation of an inverter is stopped and therefore a system of a user (consumer) is brought into a malfunction state, the user usually makes a contact via either a telephone or a facsimile to a user support center (acceptance) which is previously notified from a maker (manufacturer, and product supplier) of the inverter. Then, an inverter recovery work may be carried out in such a manner that a contact is made from the user support center.
At this time, in such a case the recovery work of this inverter cannot be carried and therefore a substitute product is required. The user newly considers a necessary machine sort/ a necessary rated value of the substitute inverter by calling an agent shop, or the like.
On the other hand, such a user who tries to newly conduct an inverter, only such a business prospective request may be contacted from the user support center to a business branch/ agent shop.


The above-described conventional inverter maintenance system owns such a problem that this conventional system cannot sufficiently and rapidly accept various sorts of contacts made from the users, but also cannot solve these user problems in good sense.
Also, even when a substitute product is required, the user newly must notify both machine sort/ rated value of such a substitute inverter to the agent shop.
On the other hand, even in such a case that such a contact communication is given to the user support center as to a business request for newly conducting an inverter, in accordance with the conventional inverter maintenance system, this user support center asks for usage of the user to give an advise of selecting a proper machine sort, and then, merely introduces a business branch, or an agent shop.
Furthermore, while such a failure occurrence example, a trouble solving example, and also a business request example are useful as information about a manufacture history. However, in the conventional inverter maintenance system, these examples are stored in a server and the like in a time sequential manner, and then are merely processed as temporal information by the user support center. Thus, these examples are not effectively utilized for user support purposes.

DETAIL DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS
Reference may be made to figure 1 which shows block diagram of a power backup system with the facility to change the various parameters and to feed information as per the requirement. The system comprises DC/ AC and AC/ DC charger, secondary storage


device, Remote monitoring and control unit, displays energy meters to measure the energy consumption, and signal conditioning circuit. The present invention is a power backup system having a controller which can be any type of controller such as but not limited to the microprocessor, microcontroller, DSP/ DSC or FGPA or any new generation controller. The invention has a port to connect the external devices from which the manufacturer or authorized person can feed all the parameters and information such as but not limited to the lower battery cutoff level, battery charging current, battery boost voltage, output frequency, output voltage, change over time, mains input window, battery type and capacity, authorized person and user's details etc. The present invention has a real time clock (RTC) which starts counting from the date it has started/ installed. The RTC is used for various other parameters and to put all the reports of such as without limitation alarms of overload, short-circuit, battery low and battery charge-discharge cycle or other specified conditions. The invention further provides a power backup system with built-in time delay relay (TDR) switch which is activated by the authorized dealer as per requirement.
The power backup system has a port to connect external device that is connected to get the record of all the parameters monitored by the power backup system including other information related to user. During the alerts or abnormal conditions, the user deactivates or activates some of the operations through external device.
When the user purchases the power backup system, he/ she (the user) performs the user registration. For registration process user has to connect the power backup system with any of the intelligent processing unit such as but not limited to laptop, computer, or any other mobile devices such as cell phone tablets. The user can connect his handheld device by using any of wired or wireless communication


media to interface the power backup system. The fields are available for registration. So, when the user purchases the power backup system, he/ she enters a user name, contact details and usage. The same power backup system information is identified with manufacturer/ authorized user's historical information and troubleshooting information saved with the system. In case, any failure happens or the system needs any service, a substitute product or suitable service engineer is quickly available at the user's location. There is provided a remote monitoring and control system in system that records all the events and keeps on transferring all the details to remote location where it is stored and being tracked.
The invention provides a secure method of operating a power backup system with password facility. The user sets/ registers the appliances such as but not limited to cooling devices, audio/ video systems, personal computers/ laptops, lighting equipment or any other device etc. The name and model of the appliances are stored in the power backup system. This is done by graphical user interface application. Once appliance (s) runs with the power backup system, the value of energy consumed is registered in the system. The energy meter in the power backup system gives the information about the remained capacity and displays what other appliances can be added. So, one by one the appliances can be switched on. The rating of stored device list in the system gives real-time information on system performance. When any load is switched on through power backup system the energy monitoring device in the system calculates the power profile including the current and voltage and also the system remembers the starting current and the running current once that appliance is switched ON along with the other appliances. The power backup system displays the list of all the products running from storage parameters.

The user checks the backup time of the system by the comparison of the records of the battery and the earlier stored values. Also the user sets the required back- up time and a power backup system fixes the load. The user has various back up time options by changing the load by the user. The user sets the power backup system in sleep mode where by the power backup system shutdowns in case of the no load condition and turns on automatically within specified time if load is switched on.
In an aspect of the present invention, the details of the authorized user are stored in the system. The authorized user selects the type of the battery attached to the power backup system along with the capacity, charging current and cutoff values. The authorized user feeds and activates the alarm for the warranty. The moment, the power backup system is out of warranty the display on the power backup system starts showing the same message along with the alarm. This message is sent to the authorized user as well as the manufacturer through SMS, call or Email. Alert messages are being recorded which helps the authorized user to understand the product better in case of failure or abnormal conditions. The manufacturer sets the password or any type of authentication for protection for the same and is shared as per the requirement.
The service engineer registers the service details such as but not limited to the identity code, name, product code, fault date & necessary actions are taken to solve the problem which are retrieved by the dealer. Power backup system keeps the records of the changes made by the user/ authorized person.
The invention further provides a system to be activated by the authorized user. During installation, system has option to give the back up for the first time when the battery reaches to the charged


condition. The present invention does the metering on mains mode and power backup system mode.
Battery discharging algorithm is implemented to give the user an estimate of the remaining back up with the existing load and battery health. The power backup system ensures the synchronized switching from mains to inverter (backup mode) and vice versa.
Inverter has an option of soft-start or to start from fixed amplitude. Thus to switch to inverter mode during the power failure the inverter is required to begin the output wave form at certain amplitude in order to sustain the load without a lapse in the power. The settings are performed by using GUI application. The GUI provides all possible options by using advance user interface for ease configuration.
The software programmable "specific start angle" feature is available in the present invention. User is required to connect the device with the GUI application and configure the "specific start angle". User has to select this option enabled and puton the desired start angle as per the guidelines. This assists the firmware in immediately starting the PWM output waveform from the desired angle within the same cycle or as chosen right by the software. The output is limited by the software when the output feedback sense stops functioning. This feature prevents the output from going above a certain limit in abnormal/emergency situations. The authorized person keeps the records of various types of the batteries installed by the user and their behavior for the analysis of the batteries and system.
The power backup system is connected with the Ethernet externally or internally so that user or authorized user can connect the power backup system to the central server. The moment user connects the system and connectivity establishes it automatically goes to central server and the user registers himself/ herself for warranty or any


other issue. Thus updation and diagnosis is done in case of any problem. The user connects his computer to the system port and registers himself to the central server. All requisite details of power backup system is stored in remote server for various purposes such as but not limited to evaluating warranty period, system id, name, user name and contact details. Also the system sends various usage level information to central server for performance evaluation. The remote monitoring and control feature enables the power backup system to broadcast the alerts and events when ever they occur. The central monitoring system keeps tracking the details of all alarms whether they are critical or non-critical. Also there is a provision in power backup system to escalate the alarm to predefined personnel.
In an aspect, the present invention is a power backup system with user based graphics where the user switches on and off any particular appliance, measures the power consumptions and calculates the total cost of the electricity consumed for any time such as but not limited to day, month or year etc. The user switches on and off an electrical appliance and has complete metering i.e. parallel metering system in the home. The provision to prioritize the loads is provided through which the load can be switched-on/off any point of time for managing the backup accordingly.
