12.8 KW Lithium Battery Versus Diesel Generator:

Battery Energy Storage Systems, which consist of Lithium batteries as a backup solution and comparison of Diesel Generators, is a new area of study. As Diesel Generators and other problems are polluting the Environment associated with the storage of Diesel, Vibrations, maintenance, noise Level and cost of running need to be discussed in this article. As the cost of Lithium batteries is coming down each year and the cost of Diesel is going up every year, the parity of both technologies is coming closer. Lithium batteries can be charged through solar, wind and grid in the BESS, and the cost of Electricity is much lower than the Diesel per unit cost for the Generator. So, we will compare the Capital cost of both products alongside the running cost and benefits of each product here.https://suvastika.com/difference-of-diesel-generator-and-lithium-inverter-for-home-use/

With the 12.8KW Lithium battery bank, one can easily install a 20KVA or 30 KVA Battery Energy Storage System. Here, the backup time will depend on the load variations. As the Load in a home office or commercial establishment varies accordingly, the Diesel generator’s running and BESS’s running costs are important to calculate.

So, let us compare the 20 KVA generator costs in India and the BESS costs to compare these two technologies.

Sure. Here is a comparison between a 12.8 KW Lithium battery and a Diesel Generator:

Feature	12.8 KW Lithium Battery	Diesel Generator
Fuel Type	Electricity	Diesel
Initial Cost	Rs 7-8 per unit	Rs 25-30/unit
Maintenance Cost	zero	Rs 2-5 per unit
Lifespan	7 – 10 years for the battery, and Lithium Inverter life is 25 years	Ten years
size	very compact can be kept inside	the size is very big and can be kept outside only
Environmental Impact	No impact	High

The Power Quality: The Generator waveform has the THD, which is not as smooth as the BESS as the BESS has the Pure Sinewave and accurate frequency and as the Load varies, there is no deterioration as the Generator Waveform keeps varying along with the small change in frequency. So, the THD of both Generator and BESS are not comparable.

3 phase Waveform of BESS

BESS provides instant power backup.

One of the main benefits of BESS is that, unlike DG sets, which break in the event of a power outage, ESS does not have this problem. This technology has no jerks or breaks as it starts immediately. BESS is automatic and seamless, starkly contrasting to DG systems that require roughly a minute to resume the Electricity through the Generator.

The running cost of BESS is low.

The cost of running a diesel generator is three times or more than the power provided by the power company, making ESS a special and less expensive solution than running a diesel generator.

As the BESS has a battery as a backup, the consumption per unit of Electricity produced is further decreased in cases of 50% or 70% ESS loading, as opposed to diesel generators, where the cost is unaffected by lower Load because the diesel consumption doesn’t vary significantly.https://suvastika.com/products/energy-storage-system/

BESS has a longer lifespan

The BESS has a shelf life of 50 years as compared to the diesel generator’s 10-year lifespan. Even their battery can last between 7 and 10 years, representing significant cost-savings.

ESS is easier and cheaper to maintain

Diesel generators contain moving parts and require a battery to start automatically, making it important to service them every 300 hours or even less in some cases. Since a DG set includes moving parts, we also need an attendant to fill it up with Diesel. However, an attendant is unnecessary for the ESS because it has no moving parts.

IOT-based monitoring: The BESS has an in-built system to monitor each parameter on the mobile phone or the computer, and the Self Diagnostic feature is there to do the diagnostics remotely and find the faults. Every BESS has the feature to update the latest software remotely.

BESS can run on Solar

The cost of the system can be recovered in 2 to 3 years if we include a solar feature that allows the batteries to be charged using solar energy. Since solar panels can last up to 25 years, the cost of power generation is also significantly reduced.

There is no substitute for such a low cost of Electricity because the solar-powered ESS can be built anywhere there is space for solar panels and where solar energy can be used effectively. Even with power on the grid, this system can run on solar and battery power if available since the power cost will be far lower per unit than the cost of grid power. This will save money on Electricity even when power is available on the grid.

Therefore, it is safe to say that ESS is the future of power backup, given all these benefits over DG sets.

The cost of a Diesel Generator of 20 KVA is approximately four lakhs, and the cost of a 12.5 KW battery with a 20KVA Lithium Inverter will be less than four lakhs, where the cost of purchasing Diesel becomes zero. The life of the battery will last for at least seven years, and the cost of Diesel one will buy will be more than 2 lakh a year. So clearly, the Battery Energy Storage with Lithium battery will be a clear-cut winner.

Ultimately, your best choice will depend on your needs and preferences. If you are looking for a quiet, clean, and low-maintenance option, a 12.8 KW Lithium battery may be a good choice. However, a diesel generator may be a better option if you are on a tight budget or need a generator that can be used in areas with frequent power outages.

9.6 kWh Lithium Battery ESS : A Comparison with Lead-Acid

Let us compare this 9.6 KW Lithium battery LifePO4 to the Tubular battery bank of 15 numbers of 150 Ah batteries, which will compare the life cycle, price, weight, size and maintenance aspects of these types of batteries. When we put the 8 KW load by the inverter having 10KVA/180V, we try to take the backup time on 8 KW, and based on that, we find the price difference between lithium and tubular battery banks. The results are that the Lithium battery of 9.6KW on 10KVA/96V gave 1 hour and 20 minutes at the discharging current of 83Amps, and in the case of the Tubular battery bank having 15 batteries of C20 capacity gave us 1 hour and 10 minutes, approximately where the discharge current was 45 Amps approximately. So, based on this, the average cost of a Tubular battery is approximately Rs 12,000 in the Indian market, and the cost comes to Rs 1,80,000 if we add the cost of rack and installation cost, which is another Rs 10,000 it touches Rs 1,90,000 of Tubular battery bank cost. So the price of a Lithium battery of 9.6KW with the comparative tubular battery price is cheaper. As the cost of a Lithium battery will be Rs. 1,50,000-200,000

ure	Lithium LifePO4Battery	Tubular Lead Acid Battery
Price	Rs 15,000-20,000 per KW	Rs 21,000-23,000 per KW
Cycle Life	2000 cycles	400-600 cycles
Weight	80Kgs	950Kgs
Maintenance	Not required at all	Need to regular distilled water topping
Environmental Impact	completely environmental friendly	Lead and hydrogen fumes are emanating all the time

9.6 kWh Lithium Battery ESS : A Comparison with Lead-Acid

Energy Density

Lithium-ion batteries have a much higher energy density than lead-acid batteries. This means they can store more energy per unit of weight or volume. For example, a 9.6 kWh lithium-ion battery weighs about 80 kg, while a 9.6 kWh lead acid battery weighs about 950 kg.

Cycle Life

Lithium LifePo4 batteries also have a much longer cycle life than lead-acid batteries. This means that they can be discharged and recharged many more times before they need to be replaced. A lithium-ion battery can typically be cycled 2,000 or more times, while a Tubular lead acid battery can only be cycled 400-600 times.

Safety

Lithium LifePo4 batteries are generally considered to be safer than Tubular lead-acid batteries. This is because they are less likely to explode or catch fire. However, the lithium-battery bank has a built-in battery management system with many safety features, and the cell equalization mechanism helps the battery bank give more cycles. The built-in BMS protects the lithium battery from overcharging, low and high battery protection, and overload and short circuit protection.

Temperature: The backup time in the Tubular battery is greatly affected in case of temperature is less than 10 degrees or higher temperature of more than 50 degrees, and the life is also reduced for which Inverter/UPS or Solar Inverter should have the ATC feature to take care of the temperature variations. In the Lithium batteries, no such change happens.

Cost

Lithium battery is cheaper than the Tubular battery at the discharge rate we have compared here.https://suvastika.com/lithium-battery-is-cheaper-than-tubular-battery-in-ups-inverter-usage/

Environmental Impact

Lithium-ion batteries are more environmentally friendly than lead-acid batteries. This is because they do not contain lead, a toxic metal that can contaminate the environment.

Overall

Lithium-ion batteries are the better choice for most applications. They have a higher energy density, cycle life, and safety. They are also more environmentally friendly. However, they are more expensive than lead-acid batteries.https://www.pv-magazine.com/2022/05/05/stackable-home-battery-with-9-6-kwh-to-38-4-kwh-of-capacity/

Here is a table summarizing the key differences between lithium LifePO4 and Tubular lead acid batteries:

Feature	Lithium Ion Battery	Tubular Lead Acid Battery
Energy Density	Higher	Lower
Temperature	-20 degrees to 60 degrees	10 degrees to 45 degrees, after which it needs an ATC feature
Cell Equalization	Yes	No
Protections	Overload, Short Circuit, Low battery and High battery	No protections at all
BMS	yes	NO
