Advantages of Lithium Battery V/S Lead acid Batteries
Comparison of Inbuilt Battery ESS V/S Traditional UPS/ Inverter with lead acid batteries
| Parameter | INBUILT LITHIUM BATTERY ESS | TRADITIONAL INVERTER WITH LEAD ACID BATTERY |
| EFFICIENCY | ESS runs with powerful Inbuilt Lithium Ion (LiFePO4) Battery, which has 3 Time higher efficiency than traditional batteries resulting higher back up and output | Traditional Inverters battery have lower efficiency as compared to Lithium-Ion battery |
| ALL-IN-ONE BACKUP | ESS system is all you need, whether you want to use it for IT/any other sensitive loads and Lighting/home appliances load. It can handle every appliance perfectly without having to buy a separate unit for every backup need in the home. | Users need to buy different Inverter systems for IT equipment and lighting/home appliances load, which means double the cost. |
| LOOKS | ESS looks stunning and modern and perfectly blends with any environment. Its beautiful design is difficult to match with any traditional inverter on the market. | Nothing can be as bland as a traditional Inverter. These inverters look really clunky and are so big that they are bound to look out of place no matter where you keep them. |
| SIZE AND SPACE | The sleek design of ESS ensures that less space is needed. No trolley is needed to stack the battery as is inbuilt inside the ESS. With sleek and elegant design, it can be kept anywhere in the house like drawing rooms | The tubular battery is very heavy and bulky, making it mandatory to change it every 2-3 years. This is quite difficult and cumbersome as it will need two people to hoist it, and if you have stairs, it will be 5difficult to get the 70 KG batteries inside for installation or repair. Additional trolley is needed to store the battery. |
| PORTABLE | ESS weighs just 25% of a typical lead-acid based traditional Inverter, hence, it can be used for multipurpose. If one is going out for a short trip, they can take the ESS with them and use its power to give back up to laptop, music systems, mobile charging, camping and all. It can run for up to 20 hours if fully charged. | Traditional Inverter and Lead acid batteries are very heavy and are not portable |
| COMPACT, SAFE, RELIABLE, EASE OF HANDLING | The ESS set-up is clean and safe for everyone in the house. Contrary to the traditional inverter, there are no hanging wires and terminals with ESS which can be hazardous to the safety of children and pets at home | In most of the cases, when the user or dealer refills the battery water than after the battery is charged the water comes out and creates havoc as the water contains acid and the floor is damaged permanently. Hanging wires and terminals can be dangerous to the safety of children and pets at home |
| NO MAINTENANCE/ REFILLING OF BATTERY REQUIRED | ESS doesn’t require refilling as it has a rechargeable LiFePO4 lithium-ion battery. | Tubular batteries with traditional Inverters need refilling of water periodically and it must be done with distilled water each time. Since most consumers and dealers are unaware of this requirement, they frequently use alternative types of water, further shortening the battery’s lifespan. |
| SPILLING OF HARMFUL BATTERY WATER | ESS is based on LiFePO4 battery, which doesn’t require any harmful liquid refilling. It is easy to manage and replace, making it completely safe for kids and pets | Refilling of battery water can cause water spillage. This water contains acid, often damaging the floor. It is also hazardous for kids and pets, making it a non-family-friendly option. |
| CHARGING TIME | ESS gets charged in 3 hours as the Lithium Ion battery charges faster. It can be used 4-5 times a day. Ideal for areas with frequent power cuts, such as India. | Lead acid batteries, especially tubular batteries, take a minimum of 10-12 hours to charge. In winter, acid and water expand and contract, so they can be used only once during the day since the charging takes more time. |
| LOW RUNNING COST/ LOW CONSUMPTION OF ELECTRICITY | Since charging time of ESS is 1/4th that of a lead acid battery, it uses less electricity than traditional inverter by at least 30%.
Being a smart inverter, ESS automatically chooses the best AC power source for battery charging and supporting load during the day, which lowers the power consumption for battery charging and lowers the cost of electricity. | Lead acid batteries, especially Tubular batteries, continue to charge even after being fully charged, which drives up the cost of electricity.
Therefore, even when there are no power outages, traditional inverter uses at least 1 unit of electricity. The bigger size of Inverter/UPS even takes 3 to 5 units per day. |
| LIFE OF THE ESS | ESS has long life of 7 to 10 years as Lithium ion batteries are required to change in 7 to 10 years. It has an extremely long lifespan (3000 cycles) due to a discharge rate of just 20%. | Due to the Lead Acid battery’s dependence on constant water filling, which the consumer cannot monitor, it has a much shorter lifespan than Lithium ion battery and needs to be replaced in every 2-3 years. |
| EASY INSTALLATION | The Installation of ESS works on Plug and Play model which is completely hassle free for every household. | Need and engineer/expert for installation, connections and settings for Traditional Inverter with Lead acid/SMF batteries |
| NO MANUAL SETTINGS | ESS requires no manual intervention, even when it comes to settings, making it hassle-free for everyday users. | Traditional inverters settings need to be set as per individual requirements, which means you are always in need of an expert. |
| SWITCHING TECHNIQUE | ESS has a fast switching technology which is required by the IT equipment and the heavy machinery which gives them uninterrupted power to them in case if power cuts or power failures. Su-vastika uses advanced Static switches in its ESS that reduce switching time to just 2ms to 5ms, which is fast enough to prevent a computer and most sensitive equipment from resetting. | Traditional Inverter has long switching time which interrupts the working of equipment till battery mode is active |
| BACK UP TIME | ESS’s unique Lithium Ion batteries takes significantly lesser time to charge. In other words, in situations where there are frequent power cuts, ESS will provide greater back up hours simply because of its ability to charge faster. | Lead acid based Traditional Inverter takes greater time to charge and still provides lesser back up time throughout the day. |
| HIGH POWER QUALITY | When a load is connected, ESS produces pure sine waves with lower THD than traditional inverter. Due to the extremely low THD variance, ESS generates Pure sinewave output and pure power is continually maintained for IT loads like computers, printers, routers, etc | Traditional Inverters are available in Square wave or Sinewave. When a load is connected to an inverter, the THD always changes, which causes harmonics and is bad for sensitive loads, especially IT loads. |
| POLLUTION AND HEALTH HAZARDS | Fitted with Lithium-ion batteries makes ESS more environmentally friendly as it can be recycled economically. There are no harmful fumes to worry about. The set-up is clean and safe for everyone in the house. | Traditional inverters emit harmful gases that pollute indoor air. It also ends up in landfills which causes land pollution. High-intensity fumes of lead can cause long-term diseases. Lead vapours from the lead acid battery are released in high concentrations when it is charged and discharged, making them extremely dangerous for children and adults. These lead vapours can cause long-term illnesses in people because they immediately enter the bloodstream and raise the level of lead there. |
| SELF DISCHARGE WHILE CHARGING | ESS has the new technology in charging. Lithium-Ion batteries are charged faster and once charged 100%, it does not need charging to maintain it to 100% as its self-discharge is very low as compared to Lead Acid battery. | The lead acid batteries specially Tubular batteries never stop charging even when they are charged so the trickle charging keep happening which increases the electricity bill and affect the battery life |
| FULL CAPACITY AT DIFFERENT DISCHARGE LEVELS | The Lithium Ion battery enables ESS to run any load to its full capacity of 100% unlike | Lead-acid based Traditional inverters which if discharged at the rate of 50%, will give only 50% of its rated capacity. |
| SELF-DIAGNOSTICS | ESS provides a self-discharge measurement and a self-diagnosis feature which means no manual intervention is required. | No self-diagnosis mechanism, which means technicians might need to conduct multiple tests to even diagnose small errors. |
| BLUETOOTH/WIFI (Optional) | ESS comes with optional Bluetooth/WiFi connectivity which allows remote monitoring & control. Using the dedicated app, you can now easily check your ESS status and monitor and control it even when you are away. One can also do Remote diagnosis of system by fetching the data through Bluetooth/Wi-Fi | Traditional Inverter has no Bluetooth or WIFI capability, which is really inconvenient for modern users. |
| GPS | ESS has an optional GPS feature that makes it an Anti-theft product that is immune to theft, as you can find its location in real-time. | Traditional Inverter can be easily stolen when you’re away from home on vacation, or when you’ve left your home unprotected. There is no option to track it without GPS |
| REMOTE DIAGNOSIS | One can diagnose ESS system even remotely if you have your smartphone with you. With it’s Wi-fi connectivity feature and dedicated mobile app, you can monitor, diagnose and generate reports without having to be physically present. | There is no support for remote diagnosis, meaning whenever there is a problem with your Traditional Inverter, you have to be physically present to do any kind of diagnosis. |
Hassle free Maintenance
Maintenance is required in In-built lithium BESS while in SMF-based built in UPS need to change the battery, and sometimes multiple SMF batteries need to equalize over six months. The Inbuilt lithium BESS has the BMS system to control the parameters of the Lithium battery.
As compared to Lead Acid batteries, no water topping is required which creates a security hazard also in today’s world. Lithium batteries are made of Lithium LifePO4 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.
Fast Charging
SMF battery will charge in 10 hours minimum, whereas the Lithium Inbuilt Battery ESS 7.5 KVA will charge in 2 hours in Inbuilt Lithium BESS. The charger size in the Inbuilt UPS is very small as the SMF battery is of small size and needs to charge in 10 hours, whereas the Lithium battery capacity is higher and needs to charge in 2 hours, so it needs a fast charger of higher capacity.
No Switching Time
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.
Very Long Life compared to Traditional Inverter/UPS.
Inbuilt Lithium battery Life is a minimum of 10 years and can last for 12 years, and the Lead acid battery lasts only a maximum of 2 years.
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
Bi-Directional Technology
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.
Isolation Transformer
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.
Ability to handle Overload
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 4 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.
Ability to handle Short-circuit
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. 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
Saving in electricity bill
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.
More back up time in less capacity of battery ESS
Normal in-built UPS can work for 15 to 30 minutes whereas our models can work from 1 hour back up time to 3 hours or more back up time.
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
Having built SMF battery and Lithium inbuilt BESS, has a price difference of 50%, but the life is five times the battery life of the same capacity.
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 LifePO4 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.
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.

Weight and Space required to install Inverter/UPS Vs Battery ESS
Battery ESS consumes 1/4th the space as compared to traditional home Inverter/UPS with Lead acid batteries. The built-in Lithium battery size is 1/4th the size of an SMF Lead Acid battery and 1/4th the weight of a lead Acid SMF battery. The battery density in the SMF is higher compared to Lithium batteries.
The size of the Inverter/UPS with the tubular battery can not 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
Pollution Vs Clean Technology
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.
Recycling of Lead Acid Battery
Better protection for Sensitive devices
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.
Automatic Voltage Regulation
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.
Ability to control ESS wirelessly (Optional)
Su-vastika has developed Bluetooth and WiFi app for all its Inverters/UPS/Home UPS/ Solar Hybrid PCU/ERD/ESS that helps to monitor and control UPS through Mobile app or direct PC and loaded with the patented software.
This feature offers many advantages over regular Traditional Inverters/UPS.
- Ease of installation
- Remote monitoring
- Real-time data
- Digital Warranty
- Voltage and frequency
- Shows charging percentage of the battery
Digital warranty
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.
Peak Power tariff-ready BESS
The one important feature that makes it future-ready is the programming for the Peak Power tariff-ready BESS, which can control the power storage and usage per peak power timing. One can program the timing for charging through the Wi-FI-based application and set the Peak timings in the BESS so that BESS will switch off the Mains power and work on the Lithium battery when the user programs the peak power timings. This will reduce the power bill of the user in the peak timing.
As all developed countries have this concept of peak power Tariff and normal power tariff in place, the developed countries are slowly bringing this concept. India has already announced peak power tariffs in the residential sector. The peak power tariff is in operation in India’s commercial sector already.
