Good and more explanation and thanks 👍

[@shivanandhadpad7271]

Best content... Thanks for making this video

[@jacksonfarias1832]

wonderful,Cheers

[@Bishnahpigeonupdate]

One of the best vedio ever on utube

[@Nid3031]

Thank you so much for simple calculation and precise method of load calculation

[@HarjeetSingh-ys8yp]

Great skil

[@purushottamraj1]

Thank you sir

[@gouravkhanra1375]

Thank you...very useful. Very simple way it is described.

[@hamjalaansari9547]

Thank you so much for giving this great video
I really tell you that
Wow wonderful

[@ashuqhussainfakhri9004]

thank you very much

[@JaiBharat358]

Thanks 🙏

[@ahmadanwar7333]

Thank you , Well done

Volt*Ah*No's*60minits/VA
12*65*34*60/60000=26.52 minites
12*65*34*60/33000=48.21 minutes
12*200*34*2*60/500000=19.58 mi
12*400*34*60/190000=51.53 min
515.2*64*3*60/300000=19.78 min
515.2*192*1*60/225000=26.37

may be blessed

Thanks

[@habib.h.i]

06:31 you need check battery datasheet to confirm battery can handle ~1200Ampere within 19Mins

[@habib.h.i]

I check one of battery datasheet cannot handle even only for 5 mins

[@skkkkk2997]

Sir , 500kva ups always connected in phase system so current (load) js different

[@nmuralikrishna6343]

Hi, Why dont you considering voltage when there is 2 battery bank and 3 battery banks? Adding of AH means we need to consider 2 battery banks voltages also

[@kaifyhussain3328]

Sir, please make a video on how to do ups on bypass mode? Inverter mode? Like that.. please

[@tanveerelahi]

kindly explain the series connection.. i thought batteries in series is dangerous

[@arunmandloi8726]

Sir, how can we replace lead acid battery with lifepo4 battery in ups, what modifications we will need

[@LibanMussa]

is the calculation same for 3 phase and single phase?????

[@sarawansaini]

I have Eaton E9 UPS. Single phase 220 and my power load is 7 amps. If I give that 7 amp load to this 10 kva UPS then how much backup will I get. Please tell me.

[@matzz6075]

brother u have to calculate not in 12V nominal battery voltage but in End in voltage battery that is 10.2 V

[@workakash9256]

Sir why have you not done 408 volts mulitply by 2 becoz its 2 battery bank??
And just added ampere hour 200+200???

[@vijayraju2379]

Because in series connection the battery voltage is constant value and current is added

[@JithuShaji-pl3dm]

Same doubt

[@JithuShaji-pl3dm]

I think the both battery banks are done with parallel then current should be i1+i2 =400 AH and voltage should be same

[@sumonk.mondol7388]

@@vijayraju2379 In parallel connection the Voltage remains constant :)

[@electrowashyelect9715]

Meaning a mall of 30kva generator will be better on ups of 100kva @ 512v 200Ah lithium battery on 20-10% load

[@electrowashyelect9715]

Also complemented.with solar array

[@shreekantgoud5919]

how to know the KVA percentage?

[@akashwankar2210]

Battery back up formula
Battery v x No of battery x pf battery x Battery Ah / Load kw = back up hrs/ Min

[@aravindsubramaniam7930]

why did you not calculate losses in lead acid battery and UPS . what about C - rating

[@shivuarsu464]

Can you put × 60 where something is lost?

[@jacobvargheseraj1774]

KVA or KW??

[@virusingh1405]

Sir ji hmko 10kva 120 ah ka battery bakeup pta krna hai kaise kre thoda btao plsload 15% h

[@seshireddyvatti4449]

There is no sound from 4 minutes sir pls once check it

[@IFM-Technical_Operations]

Yes, Sorry... one slide audio missed, pls refer last slide (from 9min) Lithium- Ion batteries, calculations are similar for Two Battery bank, only thing we need to add AH for two battery banks.

[@87saravana]

I remember you teaching me the same concept 10 years ago and I still have the working sheet written down by you with me. Great going Santosh

[@electricalwithtech.3681]

Sir u have 2 battery bank but u not calculation,, u calculate only 408v it's only one battery bank voltage

[@EngrArifIqbal]

Yes that why calculation goes wrong

[@shivuarsu464]

For everything, the last final into 60 is not for what

[@jainendrasingh8434]

Hindi me nhi bol sakte ahaha kr rhe ho guru ji

[@rajeshmohan7881]

You are not considering Depth of Discharge. So your calculation is practically wrong.

[@maheshworld4933]

Sir do you have right calculating can you share

[@pratap2446]

This is wrong.. Voltages vary with discharge..

[@vijayraju2379]

No it's correct because the battery voltage is Nominal 12volts only

[@EngrArifIqbal]

Wrong Calculation brother your Calculation is not accurate
