FIELD OF INVENTION
The present invention relates to a user settable power backup system. More particularly, the present invention relates to a user settable power backup system with multiple outputs to supply power during power failure.
BACKGROUND & PRIOR ART OF THE INVENTION
In case of the inverter device which is to be used with different appliances, it is required to set various parameters according to the need of appliances. Therefore, the inverter device is equipped with the parameter setting apparatus for setting various kinds of parameters. The user sets various kinds of parameters, change and check using this parameter setting apparatus. It is common that parameters, such as voltage, time, temperature, current, frequency pattern and maximum frequency, are set beforehand and operation is controlled by the general-purpose inverter device currently used for the drive of appliances.
Although, a user does the setting variation of this parameter and the optimal inverter system can be built in recent years according to each use, the method of the setting variation of the parameter by the user at this time making an initial value a certain parameter set beforehand, rewriting this and going is usually.
Conventionally, the standard parameters are set beforehand where the inverter is made. These standard parameters are then set in the
inverter device, as per commercial use. Thus, the user starts taking these parameters as standard values.
On the other hand, the inverter device provided with the initializing function is also known. Here, this initializing function is a function which enables it to return the parameter changed by the user side to the data set up by the manufacture side at the time of factory shipments.
In the conventional example of the general-purpose inverter device provided with this initialization value function, the data constellation currently prepared as a canonical parameter at the time of factory shipments is a lot, and if an initializing function is performed for this reason, it will be set as the equal data same for every user.
Since the parameter by the original data set up by the user side will disappear if this initializing function is performed when re-setting the parameters, using a setting-out displaying means about each parameter in which the user is recorded separately, the parameter concerned is thus memorized in the memory.
And in the case of this conventional technology, the maker of the inverter device concerned defines the contents. A manufacturer's-standard initial-value-data group is set up. A user's original initial-value-data group, after the user of the inverter device concerned decides himself, what the maker was beforehand notified of, is set up. Then, the user concerned can choose arbitrary initial-value-data groups and can perform an initializing function.
Thus the maker, at the time of the factory shipments of the inverter device should take care of the user's concerned. A manufacturer's-standard initial-value-data group is stored on ROM (read only memory) and after storing a user's original initial-value-data group to the predetermined field of storing or EEPROM (electrically rewritable nonvolatile memory) on ROM, it makes this field write-protected area.

Further, reference may be made to the article by Alicante Murcia Region C, Federico Lorca Garcia Pinoso. The article explains off mains electricity power system in which, when the generator is switched off, the inverter uses the battery bank to produce 230v electricity silently. In doing this the inverter slowly discharges the battery bank. When the battery bank reaches a preset
charge level, the generator is automatically started to recharge the battery bank and simultaneously powers appliances that would normally be running off the inverter and battery bank. Electrical power remains constant throughout this process and the user would not notice the switchover apart from the generator starting. Alternatively when there is a large demand for power the system can be programmed to sense this and will startup the generator automatically.

This robust inverter is designed for 24/7 operation, and handles any kind of loads such as power tools, home appliances, consumer electronics and office equipments. In normal condition, this inverter transfers utility power to connected equipment(s). During power failure, it straightly withdraws battery power to continuously back up the load(s). The internal 2-stage intelligent charger, as well as the battery management programming, secures batteries from overcharge.

Figure 2 shows the flow chart according to the present invention.
DETAIL DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS:
Reference may be made to fig 1, which shows the block diagram of a user settable power backup system according to the present invention. The user settable power backup system with multiple outputs (O/Pl, 0/P2, 0/P3, and O/P 4 .. ) is connected to the multiple loads which are operated simultaneously or selectively. The system comprises controlling the complete system including the inverter 1 which provides backup during mains power failure, a controller 2, a
secondary storage device 3 and the power switches (P1, P2, P3, Pn,
C1) to switch On/ Off the load according to the priority defined by the user. The controller 2 stores and allows the setting of the priority of execution of the inverter-controlling application program. A user interface 4, communication interface 5 and display unit 6 are connected to the controller 2. The user can set the priority and parameters through user interface 4 which can be displayed on display unit 6. The present invention provides user settable power system for backup during power failure in which the value of the parameters of the multiple outputs are set as per the requirement of the user. In an aspect, the present invention is provided with multiple output having a control panel 7 which supplies power to the power backup system through generator or mains. The control panel 7 is
controlled by the controller 2. The controller 2 controls the generator according to the user settings. The generator is turned on according to the user defined conditions based on priority of the loads and battery charging takes place to charge the batteries to increase the backup time of the high priority loads. The inverter is provided with a change over control 8 to change the output from mains mode to the inverter mode or the inverter mode to the mains mode. The controller 2 also monitors and controls the battery 3 and rectifier 9.
In addition, the priority of execution of the inverter-controlling application program, the order of priority in execution thereof, and the processing time interval of execution are set in the parameter storage unit of controller 2 through user interface 4 provided on the inverter apparatus or through communication interface 5 i.e. by hand held device with keypad and screen via telecommunication means.
The controller 2 includes built-in timer so as to optimize the uses of the output power available from the power backup system based on the certain user defined conditions but not limited to the battery voltage, state of the charge and time period. The operation time of the various appliances is set as per the use. The priority and operation time of the load is defined by the user. The system can also be set to operate only when the appliance is turned on, which optimizes the current and power required to provide a backup power to the appliance for a maximum period of time.
In an aspect, at least one critical output is connected to the system through switch C1 and rest of the outputs are connected to the
system through switches PI, P2, P3....Pn based on priority. During the operation, the controller checks the user settings and controls the output load according to the settings for example if the user sets the priority of the loads according to the battery voltage, the system shuts the load which is defined at first (least as per uses) priority and supplies power to rest of the loads when the threshold battery voltage for that load is reached. When the battery voltage reaches at certain defined level for second priority, it shuts the second load. This process is repeated for "n" number of loads. The system also starts the generator when the defined priority load is shut down.
When all the loads are off and the battery reaches to the lower cut off level, the generator gets started to run the critical load and charge the battery in parallel so that it can remain operational for longer duration. The user can set the values of the parameters as per the requirement
A control means is provided in the invention so as to perform the operation required for setting out and initialization of a parameter which determines inverter control conditions to achieve the above objects.
Now, reference may be made to fig. 2 indicating the flowchart of the present invention. The main controller 2 has complete control of the system and first initializes the system to the last saved settings or the default settings, if last settings are not available. Then, it monitors all the input and output parameters. In case, mains supply is available, the loads are transferred to the mains and battery charging is done
through the supply. If mains is not present, the power backup system is controlled by the controller 2. The load are turned on or off according to the user defined settings. The status of the system is displayed on the display 6. The controller 2 configures the system through the communication 5 or front user interface 4, if the input settings are validated okay. Then the settings are saved in the memory. The system also sends the alerts and notifications to the user according to the state of the system and connected loads.
The present invention uses parallel load controllers and has a provision of setting of the parameters of load/appliance at each output as per the requirement. The system gives an alert to the user during the failure from normal running conditions of the appliance or connected load.
Further, according to the present invention, the user can change the parameters from a remote location. During the failure of grid power, the present system will cutoff the power supply to the connected load(s) at the predefined set level and will also send an alert message to the user via but not limited to email / SMS.
Numerous modifications and adaptations of the system 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.
