At a time when wifi-based UPS is innovating the inverter/UPS and home UPS market, Su-vastika’s Wifi based home solution is giving users the solace of controlling their Su-vastika’s UPS/Inverters with their smartphone.

This marks one of the first occurrences since the advent of Pure Sine Wave Technology, first bought by Mr. Kunwer Sachdev, that enables users to finally check the status of their UPS using the wifi connectivity on their smartphone.

Su-vastika UPS is a significant accomplishment for the sector as it guarantees 100% connectivity with a maximum lag of 2 seconds. 

This means that the load is immediately switched to the battery mode even if you neglected to turn off some of your appliances or lights. 

This will also give you the opportunity to remotely turn off the lights and appliances and conserve battery life so that you are not met with a dark house because the battery has run out. 

You will also have the option to choose the UPS type by switching between the narrow window and wide window according to your individual requirements at any time during the day.

Under “Settings,” you can view all the essential parameters such as Battery Type, Grid Charging Current, Priority, Low Voltage Cut, Ambient Temperature, and Buzzer.

You can now switch between the battery types if you’re using more than one battery. The options include Lead Acid, Tubular, Sealed Maintenance Free, and Lithium Ion. Battery capacity will also be shown.

Since all factors relating to your battery are continually and in-real-time checked, you no longer need to be concerned about it being discharged. Every time your Load Wattage goes into overload mode, you will be notified about it as a buzzer will go off.

Su-vastika also offers a handbook for solar installation, enabling you to set up your solar production system correctly and guarantee that your solar panels are producing the most power possible. 

Additionally, a lot of other aspects can be managed by your app, as you can see on your phone’s screen. 

As is clear, most off-grid UPS/Inverters are unable to provide a transparent view of the battery charging process when the battery is charged using solar power or solar power in combination with mains power. 

But in order to provide you complete peace of mind, our app has been created to keep you informed of significant events involving your inverter or UPS installed at your house or place of business.

You won’t need any testing equipment during installation because after you’ve verified the panel’s location, you can check the actual wattage on your phone.

Customers can also view the dust status and creation in low-wattage situations and contrast this information with data from earlier days. 

The most intriguing feature of this device is that it will make it possible to share battery charging between the grid or mains and solar, which is highly challenging to do with current products of this kind on the market.

However, operating PCs or other general loads might be tricky with a normal inverter/UPS or solar system. 

This will include settings for UPS mode or broad UPS mode.

Su-vastika even offers a buzzer option for inverter/UPS or solar inverter problems. Once the problem has been fixed, the noise may be turned off in the app’s settings.

Once your solar system is online, you can view the power usage of your solar system in terms of wattage. This can also be verified by looking for the prompt “The voltage is normal, and appliances connected are safe in this zone.”

In Mains Mode, you can view the Mains Input Voltage, Battery Status, Mains Status, Grid Charging Power, Solar Status, along with Charge Sharing Percentage. 

If the Mains goes into overload mode, you will be notified on your smartphone. Remember, even low voltage can affect the working of your connected appliances (appliances connected to your mains), so these alters must also be taken very seriously, and appropriate actions should be taken to prevent damage to your appliances.

This smartphone-based wifi solution can even sense a short circuit and prompt you to check the wiring and then reset the front switch. You can also view each art’s screen recording and all the past instances.

As you can see, Su-vastika UPS has been endowed with additional features that will keep it miles ahead of its competitors.

It is a well-known truth that when choosing a smaller battery, customers frequently find it difficult to determine if their battery has been fitted in the proper settings. 

This is because the majority of dealer staff lack enough training and are prone to making critical installation errors like entering the incorrect settings.

By including a battery image and capacity on the phone’s screen, which acts as a reference for the dealer’s employees, Su-vastika resolves this long-standing problem. 

If the end user feels that a setting needs to be changed, they can utilize this guide to make the necessary modifications.

The Government of India has granted Su-vastika a patent for “An IoT Based System and Method For Multiple Battery Selection” as a result of the invention in this industry.

ATS for PCB Testing: A Revolutionary Software By Su-vastika To Check TP Points Of PCB

Most people experience a fearful heartbeat skip when the word “test” is mentioned. Taking an exam has a certain daunting quality that appears to have been ingrained in us since our first days of elementary school. But everyone is aware that testing is a crucial aspect of life. The thought of a surgeon brandishing a knife while failing his fundamental anatomy class should frighten everyone, just as you wouldn’t want to ride on a plane with a pilot who failed her flight examination.

Testing is required for the circuit boards we create as well, and in their case, the testing will reveal how properly they were produced. The board needs to be set up with particular components that a test probe may reach in order for this testing to take place. Test points are these components, and it’s crucial that PCB designs have them.

Power backup and energy storage solution provider company, Su-vastika, has developed a PCB testing jig, ATS for PCB Testing, that can be used to test any PCB inside the inverter/UPS.

In this article, we will guide you through the working of our automatic PCB testing jigs and how they will make the test point checks of any PCB a super simple task.

As soon as you open the test automation program file, a Su-vastika logo will appear, following which a black screen or command screen and a QR code login screen will open, as you can see below.

Once these screens are open, proceed to scan the QR code of the PCB with the scanner or enter the QR code manually. A test window will open at this time where you will be able to view Select Test program, Start Time, End Time, NEXT PCB, among others.

Select the test that you want to carry on using the dropdown menu and proceed to manually enter/scan the serial number according to your PCB card.

At this junction, you will also be able to see the minimum and maximum values for each test point.

If the measured value comes between the middle of the mime and the maximum value range, the status will show a pass. Otherwise, it will show fail.

Now, it’s time to run our test, whose progress you can see at the bottom of your screen.

As you can note, the test has started as the software will check through each TP point one by one, whose progress you can also see in the black command screen on the left. Taking about the command screen, it has designed to show you the relay serial number, the relay which got the command, which relay is connected to which board number, the inputs it has received, the success or failure of the operation, the open & close status of meter serial, and whether the reading was successful or not.

Based on these tests, a pass or fail value will appear against each test point. For example, in the below image, you can see as the testing point for TP 01 came out to be 3.803. Since it is in the range of 3.6-3.9(minimum and maximum value), it is showing a pass status. The progress meter will also keep on increasing until it reaches 100%. At the end of the test, you will able to see the start and end time of the test and keep it for future records.

Our new software has been designed to automatically check all the testing points of our PCB card in a quick and efficient manner. These results will also give you a deeper insight into the voltage (in wattage), range of individual test points, and the measured value of each test point. You can refer to the image below for an accurate reference of the test points.

Power Storage with Renewable Energy- is it possible?

After the introduction of LiFePO4 batteries and the continuous improvement in battery technology where the density is reduced, and the life cycle is improved, and most of the world is working on these technologies has revolutionized the renewable industry.

The Renewable industry is mainly dependent on Grid feed systems where the solar is fed through the grid, which is not reliable at all as this energy is dependent on the availability of sun, which might be available at times or not. Generation companies come under stress as this power is not available continuously, and they need to regulate their generation from time to time which creates a lot of stress on the power plants and financial stress on the generation companies.

After the storage solution availability, this stress can be reduced as the big plants installed by the solar installation companies can provide stable power to the grid, whereas the Generation company can plan their power generation accordingly and is willing to give more money compared to simple grid feed solutions.

The cost of generation of power through solar will be cheap, and this can compete with the power distribution companies. Since the storage system can be installed locally and the power losses for distribution and maintenance are not a challenge, we can imagine the future scenario that people don’t need power from the Discoms.

In the future, people will be installing renewable energy systems with storage solutions like Su-vastika India-based power storage solution provider has shown. They will be sharing the power with each other through blockchain systems and will not be dependent on distribution companies.

This way, the wires coming from 100 km or more for power distribution and maintenance of those systems and losses incurred will be a problem of the past.

As the cost of the LiFePO4 batteries goes down along with density and cycle life is increased, the power generation through fossil fuels will not be able to compete with the cost of power generated through the renewable storage system.

“Would you like to purchase a square wave inverter/UPS or a sine wave inverter/UPS?”

This may be one of the most frequent inquiries you encounter while trying to buy a power converter. So what exactly is an inverter/ups? Alternating current (AC) power is used by the vast majority of home electrical appliances. On the other hand, a battery holds direct current (DC) electricity. An inverter’s primary function is to transform DC current into AC electricity.

However, an inverter/ups convert DC current to either square wave or sine wave AC current at the core of its circuits. The output of a sine wave inverter is remarkably similar to AC current. The sine wave output is purer than the square wave output, which is also the basis for the existence of the phrase “pure sine wave inverter/ups.”

What is a Sine wave inverter/UPS?

Sine wave inverters convert battery electricity into the same kind of power you receive from a standard wall outlet in your house or place of business. Sine-wave inverters specifically convert direct current (DC) from a battery into alternating current (AC).

What is a Squarewave Inverter/UPS?

One type of inverter that converts solar DC power to AC power is the square wave inverter. The square wave inverter is more effective than the sine wave inverter and has a simpler architecture. However, because of the high harmonic content’s potential for interference, the square wave will not be suitable for all loads.

The unique situation with Square-wave inverters/UPS in Europe.

You also need to be aware that if you use square-wave inverters, many domestic appliances will become hot. Square wave inverters are prohibited in some European nations for this reason.

The situation in India.

In India, the square wave Inverter, which is called Digital Inverter, is sold in the majority, especially in the Northern Part of India. For example, in Delhi, which is the capital of India, square wave inverters are still getting sold in majority in the inverter/UPS category. This is a very strange phenomenon as the service engineers and salespeople have spread the message in the industry that sinewave inverter/UPS can’t be repaired locally or the back feed current damages the sinewave inverter/UPS.

The real issue is that this industry has been driven by people who are non-technical. The majority of them were local electricians who never had any formal education in the electrical and electronics major. From one person to another, this kind of rumor made the impression in the mind of people that sinewave inverter/UPS is not a good technology for Indian conditions. 

The other factor is that majority of the companies in the industry are also to be blamed for this misinformation as most of them are still making square wave technology as their sinewave technology has more failures compared to the Squarewave technology.


The situation in Africa.

Even if we go to Africa, even in a small town, they use Sinewave technology as they were exposed to Sinewave technology during the initial phases. So now they can’t accept Squarewave technology as they know the benefits of Sinewave technology. But India is in India because inverters were started way back in the 1990s, so the initial technology was Squarewave technology only. It was only in 2002 that the Sinewave-based technology Inverter was designed first time in India by Mr. Kunwer Sachdev, who is the founder of Su-Kam, which has been made a household brand by him. He is not with Su-Kam anymore. He is mentoring Su-vastika to become the next powerhouse in the power storage solution sector..


Kunwer Sachdev – The inverter man of India.

Kunwer Sachdev is the torch bearer of Sinewave-based inverter/UPS technology. He traveled all across India and other countries to show the people the difference between square wave and sinewave technology. He explained that square wave inverter technology is the reason TVs, Fridges, Tubelights, Fans, etc are not able to sustain and go bad.  He recommends not running TVs, computers, and any sensitive appliances on the square wave inverters to avoid damage.


How do we recognize the sinewave and squarewave technology?


A sine wave inverter produces an output waveform that is a close approximation of a true sine wave, while a square wave inverter produces an output waveform that is a square wave. The main difference between the two types of inverters is the quality of their power. A sine wave inverter/UPS can produce power that is of a higher quality and is more suitable for sensitive electronic equipment, while a square wave inverter is less expensive and is better suited for powering motors and other types of load that are less sensitive to waveform distortion.

If we run the fans on the square wave inverter/UPS, there will be noise and that can easily differentiate the technology. These square wave Inverter/UPS are sold for backup for computers, monitors, and printers.


List of Features Square Wave Inverter/UPS Sine Wave Inverter/UPS


Supported Appliances


Most of the time, square wave inverters/UPS are used to power motors by themselves.

Sine wave inverters/UPS are used to power things like refrigerators, ovens, computers, laptops, and other home appliances.

Overall Safety Level

Square wave inverters/UPS don’t work as well and are also dangerous to use with appliances. Sine inverters/UPS are used in a very safe way.

Noise Interference

When they are used, square wave inverters/UPS make a very loud noise. Sine wave inverters/UPS only make a regular sound.


Less money is spent on Square wave inverters/UPS than on Sine wave inverters. Square wave inverters cost less than Sine wave inverters/UPS.


If we go to the computer market to buy the UPS as a backup, the majority is coming from china, and 90 percent are sold with Square wave.

People don’t realize that even for the computer backup, they bring the UPS, which is supposed to protect the computer, which is, in fact, destroying the Computer.


As a mentor of Su-vastika, Kunwer Sachdev has helped the company build a range of sinewave inverters that will revolutionize the power backup market in India.

How IoT is going to revolutionize the Inverter/UPS, and Home UPS market

Wifi-based UPS has brought a revolution that hasn’t been seen in the industry for ages. Indian power storage manufacturer Su-vastika is spearheading this revolution by making Wi-Fi a part of its products.

Now its users can control their UPS simply by their smartphones, thanks to the built-in Wi-Fi connectivity of Su-vastika’s UPS/Inverters.

Why is it such a big deal?

With the UPS, switching takes place without any flicker or noise in the applications, thanks to the advent of Pure Sine Wave Technology, which was first brought to India bMr. Kunwer Sachdev (founder of Su-Kam and currently mentoring Su-vastika). With the wi-fit connectivity, users can now check the status of their UPS, whether it’s working on mains or battery mode, without depending on your UPS sounds.

This makes it extremely easy for you to check the status of backup time along with load status, which will be shown on the screen (in wattage) so that you can check the consumption of each of your appliances.

You can even constantly check the voltage coming to your home or office when the UPS is working on the grid or mains mode.

In cases of voltage fluctuations, the UPS will protect the applications by switching on the battery mode, which can be easily viewable to the customer.

You will not only be notified about alerts such as overload or short circuits on your app screen but also get timely recommendations for things you can do to resolve the situation.

The power backup solution provided by Su-vastika has Wi-Fi and GSM connectivity (Optional). Our application will monitor your UPS and send regular reports to Su-vastika technicians. In case of any issues, an automatic alert will be sent, and a service call will be made.

Additional features put Su-vastika technology miles ahead of its competition.

Su-vastika  UPS  logs each alert as created and permanently stores them on our external server, which can be accessed anytime. Customers also have the option to switch on or switch off their load, even if they are sitting in another part of the world. 

Su-vastika UPS with Wi-Fi ensures 100% connectivity with a maximum lag of 2 seconds, a big achievement for the industry. This means that even if you’ve forgotten to switch off some of your appliances or lights, the load is automatically shifted to the battery mode. This will give you the time to switch off the lights and appliances remotely and save battery so that you’re not greeted with a dark home due to battery draining. You no longer have to worry about your battery getting discharged, as all conditions related to your battery are monitored constantly and in real time.

Su-vastika also provides a guide for solar installations, allowing you to install your solar generation system properly and ensure maximum power is achieved through your solar panels. Once you’ve approved the positioning of the panel, you will be able to see the real wattage on your phone while installing, thus eliminating the need for any testing equipment during installation.

In cases of low wattage, customers can also see the dust condition and the generation in real time and compare this data to previous days. The most exciting part of this unit is that it will allow you to see the sharing of battery charging through the Mains or Grid and solar, which is very difficult to achieve with other similar devices on the market.

In addition, numerous other features can be controlled through your app, which you can clearly see on your phone screen. In the conventional inverter/UPS or solar system, it is quite difficult to determine when to run computers or other general loads. This will include UPS mode or wide UPS mode configuration.

An age-old problem was finally solved.

It is a well-known fact that customers often find it challenging to figure out if their battery has been installed in the correct settings when opting for a smaller battery. This is because most dealer people are not well trained and are bound to make some crucial mistakes during installation, such as putting in the wrong settings.

Su-vastika solves this long-standing issue by putting a battery picture along with the capacity on the phone screen, which serves as a guide for the dealer’s staff. Even end customers can use this guide to make the changes in settings if they feel that something needs to be corrected.

Due to the innovation in this field, Su-vastika has received a patent for “An IoT Based System and Method For Multiple Battery Selection” from the Government of India.

The IoT-based system is set up so that the server has charging profiles for all kinds of batteries. The manufacturer of a new battery can add a charging profile, which can be programmed through the iot into the microprocessor of an EV charger, solar charge controller, Inverter, UPS, etc.

When using a solar UPS, it is crucial for the customer to conserve energy by turning off or setting the grid charging mode to a very low level. Now, they might choose to either switch on the grid power during the rainy season, when the sun is not visible for 3-4 days, or leave the UPS in solar mode.

Since these switches are quite difficult for the average customer to manipulate, most of you might not be familiar with them when using a standard solar UPS. But now, all of these capabilities will be available on the app screen, allowing you to easily range your settings from the app to save money.

Su-vastika even gives you a buzzer feature for inverter/UPS or solar inverter troubles whose noise can be switched off in the app’s settings once the issue has been resolved.

As evident, most off-grid UPS/Inverter fails to give a transparent view of battery charging when the battery is charged through solar or solar plus mains Power. But our app has been designed to keep you aware of key happenings to your inverter/UPS installed at your home or office to give you complete peace of mind.

Every household experiences voltage and frequency fluctuation in their house. For example when the voltage goes down then we can see the speed of the fan goes slow or the light goes dim in the bulbs or sometimes the tube light doesn’t get on if the voltage goes below to a certain level so that condition is called Low Voltage condition.

Also, there are times when the voltage goes very high and our sensitive equipment starts getting problems. We all have experienced this condition when sometimes we get up early in the morning and we switch on the light and it goes fut and we realize the bulb got fused because at the time of the early morning, the voltage is generally high because the Load on the grid is minimum. So we define the voltage into three categories

  • Low voltage condition
  • Normal voltage condition
  • High voltage condition

It is to be noted that low as well as high voltage conditions can pose a threat to your appliances.

Therefore, in order to cope with such situations and provide protection to your appliances, our inverter/UPS consists of AVR (automatic voltage regulator). Accordingly, whenever the voltage level rises or drops to an undesirable level, the inverter/UPS automatically switches off the mains and connected appliances are run through the battery to keep them safe all the time for your peace of mind.

II Extra Protection – MCB/Special Resettable fuse.

lithium battery

When we design our UPS than we make sure that we provide you with an extra window for the load. So, for example, our UPS which can run the 800 VA load we give you the option to connect the 2000VA load approximately so that in case of emergency, you can switch between the loads and also, this feature help you to give extra protection to the connected load so that they can be protected for the low and high voltage protection.

So, for example, your whole house is connected on the UPS and your fans, lights and washing machine, fridge, etc are connected with the inverter and suddenly high voltage comes and in that case, MCB of your house will not protect those appliances, but our feature in UPS will help those appliances to switch to battery mode and in case the load is higher than the UPS will give a warning and stop the output and you can reduce the load and restart the UPS but in this case, if the voltage remains high than UPS will not let you operate those appliances and by switching off those appliances you can keep running essential appliances at that point. This is a big protection for the sensitive appliances at your home so we give you complete insurance by this feature.

The next big protection is the short circuit of any appliances connected through the UPS so they will be protected by the MCB or Special resettable fuse given in the UPS before the MCB of your home trips. So we give you double insurance circuitry. Thus, providing first and extra protection to your appliances.

III. Automatic bypass

solar off grid

Our inverters/UPS are built with the Automatic Bypass feature. Its function has been explained with the help of the following illustration:-

Imagine a situation when the mains power supply is available but due to some problem occurring in your UPS and you are not getting any power unless some electrician comes and removes or replaces the UPS. In this kind of conditions, people are very irritated especially when the inverter goes bad and its the middle of the night and the Mains power is available and they can’t call anybody at that point in time and have to wait for the morning so they can call someone for getting the power connected. We at Su-vastika have seen these situations and after doing a lot of RND created a feature in which whatever goes wrong with the inverter or power you will get uninterrupted power at your disposal.

To save you this hassle, the automatic bypass feature of our inverter/UPS allows you to simply connect your appliances to the mains power supply with just the push of a button within the inverter/UPS.
