The Battery Energy Storage System (BESS)15KVA, or Battery Energy Storage System (BESS), developed by Su-vastika, is a High Capacity/Heavy load UPS with a rechargeable Lithium battery system that stores energy from the electric grid or any renewable energy source and returns that energy when needed.
The primary component of an ESS is a LiFEPO4-based battery. Su-vastika has designed ESS with high powered Lithium Ion batteries being developed by Su-vastika to offer an uninterrupted power supply with reduced charging time and higher efficiency. Battery ESS comes with Pure Sinewave technology.
Su-vastika uses advanced Static switches in its ESS that reduce switching time to less than three milliseconds, which is fast enough to prevent a computer and most sensitive equipment from resetting which offers an uninterrupted power back up to customers. Because of its strong R&D and the experience of its able Mentor, Su-vastika understands the power backup needs of its customers across industries.
Most importantly, it’s our Patent Technology as well.
At Su-vastika, we have a complete range in Battery ESS single phase up to 5KVA. ESS is capable to run all kinds of load of Commercial, Residential, Factories, Hospitals, Schools, Colleges and Hotels etc. Anyone who needs to run high Capacity Loads where home UPS/inverters are being used can also run the same load on the ESS.
The best part is we can customised Battery ESS-based power backup solutions based on individual needs. This can also run for a short duration, especially for generators where people want uninterrupted power during a power failure. This can work between the Grid and generators, and there will be no switching time.
Su-vastika Heavy Duty ESS with Lithium ion Battery is based on IGBT based Technology
IGBT, or insulated gate bipolar transistor, is a power semiconductor device used in various applications, including industrial UPS. IGBTs offer several advantages over other types of power devices, including:
- High efficiency: IGBTs can be switched quickly, leading to lower losses and higher efficiency.
- Fast switching: IGBTs can switch on and off very quickly, which makes them suitable for high-frequency applications.
- Wide input voltage range: IGBTs can operate over a wide input voltage range, making them suitable for various industrial applications.
- Rugged construction: IGBTs are typically very powerful and can withstand harsh environments.
Maintenance in the normal Inverter/UPS having the Lead Acid batteries is a big headache as the regular battery water topping is required which creates a security hazard also in today’s world.
The ESS is designed to require No maintenance at all – No water topping, No water levelling, No mineralisation, No frequent replacement of battery, etc. Lithium Ion batteries are made of Lithium ion cells which are combined and sealed in a battery pack.
That’s right, once installed, these inverters can guarantee a hassle-free experience and smooth power supply.
Su-vastika ESS has Bi-directional technology under which MOSFET circuit converts AC from the power mains into DC to charge the battery. In the absence of current from the mains supply, the same MOSFET converts DC stored in the battery into AC used by the appliances in the house. For charging the battery, the bi-directional technology provides pure DC. It uses pure sine-wave output for discharging, which ultimately increases battery life.
Su-vastika ESS comes with Isolation Transformer which is the most important parameter when it comes to be weak neutral or weak ground. All the developing countries have the major problem of weak Neutral and Voltage variations and spike and surges which are absorbed by the Isolation transformer but in High Frequency Inverter without Isolation Transformer, the failure start happening in these conditions.
In Su-vastika Battery ESS, we have added a special overload feature. In case of overload running, it will take overload protection and start giving beeps to let know the customer of overload situation. Meanwhile, it will take 3 Retries to keep the UPS running till the time customer can reduce the load so that there is no sudden darkness in the house/office.
Our UPS also has a feature of short circuit protection. With this feature, in situation of Short circuit, our ESS will take short circuit protection and start giving beeps to let know the customer of short circuit and shut down the UPS and will automatically get on 1 time. In this process, our UPS will check whether the condition of the short circuit has been eliminated or not. If the short circuit has been eliminated, the UPS will start working normally. If the short circuit has been not eliminated, the UPS will go in shut down mode and will have to restart from front switch
The ESS can work smoothly for 50 years with very little maintenance. The life of the lithium battery will be no less than ten years which is very cheap compared to the Lead Acid battery as we need to change the Lead Acid battery within 2 to 3 years of usage
The Lead Acid battery wastes a lot of energy and takes time to charge the battery. The tubular battery keeps charging even when completely charged by taking a trickle charge, an extra electricity bill for the user. If one has 800 VA inverter/UPS installed, then 1 unit is consumed by the inverter/UPS whether the power cut happens or not.
Whereas the lithium battery-based ESS stops the charging once the battery is fully charged and stops the electricity consumption.
The Lithium LifePO4 battery has a C1 rating. In contrast, the Lead Acid Tubular battery comes with a C20 rating, so once the Inverter/UPS is loaded with 8O% capacity, then the tubular battery backup reduces as this is meant for C20 capacity, but the Lithium C1 battery capacity remains the same for any percentage of the load.
Lead Acid battery, like a tubular battery, takes 15 hours of charging to provide a backup of 1 to 2 hours maximum daily. At the same time, the ESS can be charged and given backup five times a day. So if one installs a 50 Ah Lithium battery compared to a 150Ah tubular battery, then the backup time provided 50Ah by a Lithium battery in intermittent power cuts will be more than a 150Ah tubular battery in 24 hours.
Lithium Battery ESS is Cheaper than Traditional Inverters with Lead acid batteries
The life of the battery in the Lithium is more than 12 years for home and office backup purposes as the cycle life pf Lithium ion battery is 3000 cycles compared to a Lead Acid battery which gives a maximum of 400 cycles, that too if you do the proper maintenance by filling the battery with water topping in time. Lithium has 6 to 8 times the life cycle of a tubular battery, which will have a life of 12 years, in which period you will be changing at least four Lead acid batteries. So the cost of 5 Lead acid batteries compared to one Lithium battery is too low.
Secondly, the Lithium battery is a C1 battery, so one can install 50% of the battery to get the backup from the Battery ESS compared to Inverter/UPS. So one can install a 75Ah battery of Lithium compared to the 150Ah tubular battery, giving the same backup time as on a 600Watt load.
From all angles, a Lithium battery is cheaper than Lead Acid tubular battery. If we take the cost of a 70Ah Lithium battery compared to a 150Ah tubular battery, the price is almost 30 to 40% extra initially, but the life is a minimum of 4 times where the Lithium wins in the pricing part.
Battery ESS consumes 1/4th the space as compared to traditional home Inverter/UPS with Lead acid batteries.
The weight of a 70 Ah battery of Lithium compare to a Tubular Lead Acid battery is 6 Kg compare to 60 Kgs of tubular battery weight.
The size of the Inverter/UPS with the tubular battery cant be compared, and the space required to keep the tubular battery along with the Inverter UPS is too big. Secondly, you need an area with open space as the tubular battery has lead fumes. Battery ESS can be kept even in your drawing rooms with no risk of fumes coming out of it
Installing an ordinary Inverter/UPS with a Tubular Lead Acid battery is a health hazard as we install a lead fumes machine in our house or office, which is banned from all the other items available in the market. There is a buzz of Lead-Free water, Toys electronic components, pencils etc
Whereas we are bringing the Tubular Lead Acid battery in homes and offices and getting the lead fumes to reduce our lung capacity. Battery ESS is clean energy and has no lead or any fumes.
In any establishment, there are costly, sensitive devices that cannot withstand sudden fluctuations in voltage. The problem is that most power backup systems allow a sudden rush of current and cannot protect the devices from the influx of current during voltage fluctuations.
Our ESS will not just keep your sensitive appliances safe, but it will actively protect them as well. Unlike traditional inverters, which allow a sudden inrush of current, which can be harmful to your machinery, our ESS gives power when the appliances are started for the first time. It gives voltage gradually so that your sensitive devices don’t get any jerk voltage or spikes. Switching time is so quick that the equipment will not stop if the mains power is disconnected. The soft start system increases and maintains the life of the appliances.
Whenever, there is a Low Supply voltage or High Supply voltage, and the supply rises or drops below the Safe voltage range, Our ESS seamlessly switches to the battery power, keeping all your machinery and equipment safe. Moreover, the power quality produced in Battery Mode is better than the power quality provided by the electricity distribution companies or by the government as our ESS provides Pure Sine Wave output having THD ≤5%, which is a far better quality power compared to generators.
Whether the power fails, the voltage falls below the safety limit, or the voltage increases beyond safety limits, the ESS works automatically without any manual intervention.
Our ESS with Lithium ion Battery systems have Wi-Fi and GSM connectivity (Optional). Our application will monitor your ESS 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.
- Wi-fi features in ESS make 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 ESS is working on the grid or mains mode.
- In cases of voltage fluctuations, the ESS 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 ESS 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.
- Our Online monitoring System will keep track of the Battery Bank usage and send an alert when the replacement of the battery bank is required (Optional).
Su-vastika brings in a Digital warranty for Inverters, a remarkable, revolutionary, and mindful innovation by Su-vastika Systems. Su-vastika’s Digital warranty is linked with the microprocessor in the PCB Mains card of its complete range of UPS.
The warranty shall start only when Inverter is connected to Battery, and when the Battery is disconnected from Inverter, the warranty stops. By linking the warranty with the microprocessor in the PCB card of the inverters, Su-vastika has found a unique way to ensure warranty coverage that aligns with the actual usage of the Inverter.
Battery ESS by Su-vastika also comes with a solar feature allowing batteries to be charged using solar power. This way, the cost of the system can be recovered in just 2-3 years since the cost of power generation using Solar Panels is very low and they also last up to 25 years, which will further reduce the running costs.
The Solar-based ESS can be installed in various places where the space for solar panels is there, and solar can be properly utilized, and the cost to produce the electricity will be very low, there is no alternative to such a cheap electricity cost.
Battery charging will depend on the size of the solar panels installed and the size of the external solar charge controller. In this case, the Heavy-Duty behaves like an Off Grid Solar ESS, and it can cut off the mains supply and run completely on solar and batteries. This, Saves the cost of electricity, Increases the backup time, and Charges the batteries simultaneously.
Even if power is available on the grid, the solar-based system will be able to run by leveraging solar and battery power (when available), which will again save the cost of electricity.
