How Do You Calculate Amp Hours On A Battery Bank. The calculator recommend a battery with 200 AH which is still over 100 lbs of weight. Running 8 hours is a total of 9792 amps.
The boss just want a cheap and small battery with it but with no further information on how long does the end customer wants how small can it be. To do this just multiply the volts V x the amp hours AH and divide by 100. The more amps you pull out of a battery bank the less AH capacity that battery bank is which is why most batteries have several different AH ratings based off the Amp draw the battery is subjected to.
You could do a rating like this 100A x 144V 144kW.
Inverters can add on average 15 inefficiency to the power draw. It takes 1825 hours to charge half of its capacity at 2 amps 375 hours at 10 amps or 25 hours at 15 amps. Sizing a Battery Bank - Watt Hours. Input Numbers Into a Battery Amp Hour Calculator or the Formula Below.
