ENERGY STORAGE SYSTEM (ESS)
THE ECO-FRIENDLY
SUBSTITUTE TO THE GENERATOR
3 PHASE 100KVA (IGBT BASED WITH LITHIUM BATTERY BANK)
Why use an ESS?
UPS is short for Uninterruptible Power Supply, allows electrical load to keep running and provides power in the event of a power failure.
A UPS system utilizes DC power stored in the battery as its backup source. During normal operation, the power from AC mains is directly supplied to the output through a static transfer switch. At the same time, the AC is converted to DC to charge battery. When there is a power outage and primary supply breaks, the battery stops charging and the static switch transfers the output line to the inverter side very quickly. At the same time, the inverter starts drawing current from the battery which is then supplied to the AC load.
Su-vastika uses advanced Static switches in its ESS that reduces switching time to just 2ms to 5ms, which is fast enough to prevent a computer and majority of sensitive equipment from resetting. Because of its strong R&D and experience of its able Mentor, Su-vastika understands the power back up need of its customers across industries and most importantly it’s our Patent Technology as well.

ESS COMPARED TO THE GENERATOR
What is the life of the ESS compared to the Generator?
The ESS can work smoothly for 50 years with very little maintenance.
The Generator on the other hand has a life span of only 10 years and requires regular maintenance on an average of 250Hrs-500Hrs because of its moving parts.
Is it necessary to keep an attendant on site?
Unlike a Generator where an attendant is mandatory to be on duty but for our ESS we don’t recommend having any attendant. However, we offer training to the maintenance staff so that it’s easy for them to maintain without attending the ESS on a continuous basis.
Is the ESS system as noisy and polluting as the Generator?
Not at all. Generators are notorious for being noisy and causing a lot of pollution due to diesel usage, however our ESS works on batteries and has smooth noiseless operation and is completely pollution free.
Can I use this ESS with my existing Generator?
Yes, it is compatible with generators. It can be used with the Generator in several ways.
- As a secondary power backup source or the areas where mains is not available at all. The Generator can be installed at the back of the Heavy-Duty UPS. Our Artificial Intelligence (AI) based software will automatically switches the generator ON in case of low battery. This allows you to keep your devices running on the generator, while the ESS charges simultaneously.
- As a power supply to charge batteries. Our ESS can withstand a generator’s uneven power supply and convert this power to a healthy, regulated power supply that charges your batteries.
- As a temporary power backup source. In the rare case of a complete battery discharge during a power outage, our Artificial Intelligence (AI) based software will automatically put your load onto the generator with zero switch-over time, bypassing the inverter temporarily, and allowing your existing generator to act as an extra backup source. The bypass is so fast you won’t even notice!
- There are few remote areas around the world where no grid supply is available at all hence there is a requirement of two generators as one generator can work continuously for 8 hours only, after which it needs rest so the combination of UPS along with the generator is an ideal combination as the battery charging can happen while generator is working and the generator load will shift for one to two hours on the ESS after which generator can start again. This way one more generator in parallel can be saved.
How safe is the ESS compared to the Generator?
Storing fuel for Generators in commercial premises can be hazardous, as it can lead to fire in the premises, especially if the safety precautions taken are not adequate.
The ESS is safe and does not have any fire risk as it runs on batteries along with the electronic and electrical equipment.
How cost-effective is the ESS compared to the Generator?
The initial investment on machinery for both ESS and Generator is almost same, however there is a significant difference in running cost, maintenance cost & effort.
- Running Cost: The ESS runs on batteries while the generator runs on diesel. If used for the same number of hours/day in a year, the cost of running the generator is almost six times more than the UPS!
- Maintenance Cost: The ESS running on Lithium batteries requires almost no maintenance compared to generators which require maintenance every 300 running hours by trained technicians.
Manual Effort: Having trained technicians to carry out regular maintenance on every 500 hours increases the cost of running a generator further. The ESS on the other hand has mandatory checks by service engineers just once in a six months
INFRASTRUCTURE AND MAINTENANCE
What infrastructure is required?
Infrastructure required depends on the type of battery being used and capacity. Smaller backup load requirements will require smaller spaces
- Sufficient ventilation for heat dissipation is needed for Lead Acid Batteries.
- There are no special requirementsfor Lithium and Sealed VRLA batteries.
The optimum temperature for all batteries is 40°C to 50°C. However, they can also withstand temperatures ranging from -10°C to 50°C.
What type of maintenance required? Is servicing needed?
The ESS is designed to require little to no maintenance. However, at Su-vastika, we provide services to keep your products in top-notch condition: An AMC contract to service your UPS every 3 months, and battery upkeep is done regularly depending on the type of battery bank used. Our systems come with an online monitoring feature (Optional), and GSM and WIFI compatible applications that monitor the UPS and battery life. In case of any issues, alerts will be sent automatically, and the stored data can be checked on the display of the UPS.

I have sensitive devices. Will they be safe if I use ESS?
Yes. Absolutely. Our ESS will not just keep your sensitive appliances safe, but it will actively protect them as well. We have developed technologies like Soft Start System and Automatic Voltage Regulation specifically keeping your needs in mind.
Soft Start System: Unlike traditional inverters, that 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: Voltage fluctuations are common occurrences. Whenever there is Low Supply voltage or High Supply voltage, and 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 compare to generators.
GETTING STARTED WITH YOUR ESS
Do I need to manually start the system to provide backup?
No, everything is automatic, designed at your ease and convenience in mind. Whether the power fails, voltage falls below the safety limit or voltage increases beyond safety limits, the ESS works automatically without any manual intervention.
TECHNICAL SAFETY
What happens in case of a technical issue with the UPS?
Technical glitches are not likely to occur, however, we are prepared for all types of situations. In case a glitch does happen:
Our Online monitoring solution will automatically be made aware of a failure, a customer call will be logged, and service engineer will be informed with automatic response system and will try to resolve the call ASAP.
When industrial heavy equipment is running on ESS, is it safe for the person operating it?
Yes absolutely. Our built-in Galvanic Isolation System protect against electric shock and suppresses any harmful electrical noise. Our UPS system also provides better power quality than what is received from the mains supply.
What is the maximum rush load the ESS can take?
The ESS has a high Crest Factor of 3:1, which means that it can take almost 3 times the more load for the High inrush current required by some heavy machinery or motors that take very high surge current when they are starting for the first time
The largest system we have is a single ESS of 500 KVA. This can be further augmented depending upon the individual requirements. It can easily run 1MW load if 2 units are installed on site. Distributing the load to multiple UPS systems, we can ensure that the UPS generates required output voltage effectively and all your devices keep running in the event of a power failure.
Can I control the ESS wirelessly?
Yes. Our ESS systems have 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.
BATTERY BACKUP-UP INFROMATION & CARE
What type of battery would I need?
Our ESS comes with 3 types of batteries which can be selected depending on your load, back up time as well as battery life.
- Sealed Maintenance Free VRLA Battery Bank (12V size Mon block)
- Lithium Battery Bank (can be designed for any voltage depending upon the DC size of ESS range)
- Tubular Lead Acid Battery bank
What can I do if I need to increase backup time?
There are 2 primary factors that determine backup time: total load of the machines that require backup, and duration of the backup, or in other words- number of batteries to be installed.
To increase backup time:
- More batteries can be added and the battery bank can be designed in parallel.
- Solar generated power can be combined with the existing system
How often does the battery need replacing?
Battery life depends on its usage. In practical terms, the power failure in a particular area will define the battery life of the system. Depending on the battery type, if the power failure happens occasionally and the duration is also very less then:
Lithium can last for more than 10 years..
Other battery systems, if properly maintained, can last up to 5 years.
Our Heavy-Duty UPS is also equipped to prolong battery life and manage battery health:
- In case of Tubular and SMF batteries our advanced Six Stage Charging technology charges the battery in 6 stages, which helps avoid over-heating and loss of water-topping.
- The UPS prevents battery from being fully discharged, which extends battery life.
Su-vastika will always provide you with information about battery upkeep and battery life, which other companies will not be able to.
Our Online monitoring System will keep a track of the Battery Bank usage and send an alert when the replacement of the battery bank is required.
How long does a battery take to recharge after a power outage?
For short power outages batteries do not get discharged very quickly and will recharge extremely fast as well..
For power outages longer than 3 hours battery charging times depend on the battery type:
- Lithium batteries charge fully in 4 hours and 50% of its charging can be done in 1 hour.
- SMF and Tubular Lead Acid batteries take 8 to 10 hours to fully charge. If the Mains breakdown is small then the battery discharge is very less so that they get charged fast to give the 100 percent back up.
ESS is solar compatible.
Is charging batteries with solar power faster than charging with electricity?
Battery charging will depend on the size of the solar panels installed and the size of the solar charge controller. In this case the Heavy-Duty behaves like an Off Grid Solar UPS 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
- Charges the batteries simultaneously
