I am an Electrical Engineer with 6 years of experience in Residential, Commercial and Oil&Gas Projects. I have experience with the Battery Sizing module of the software ETAP. I believe can help you. Regards. Respond your question: If you have a battery bank of 32 batteries in serie then: The Voltage design would be: V= 12 V * 32= 384 V DC For a load of 64 kW, you need: I = 64.000 W/ 384 VDC = 166.667 A Considering the discharge characteristics of the battery, you need for the load: I=166.667 A.h x 1.3 = 216.671 A.h For 4 battery bank of 210 A.h you have a runtime of: Runtime= 210 A.h *4 / 216.671 = 3. 87 h

Hi! I have read your requirements and I think we can go along for a long term relationship due to the following reasons. I am working as an electrical engineer with a UPS company for nearly two years and designing battery bank solutions along with estimating backup times and preparing BOQs for installation are everyday activity for me. I totally understand the chemistry of battery types like VRLA, LiPo etc to design a solution and estimate the amount of backup time for load. Regarding your query, the backup time calculation also depends on the battery cut-off voltage and the diversity factor (percentage of load running at a time). To get an estimate, the battery bank as described will provide back-up of approximately 3.5 hours for full 64kW running load if cut-off is set at 10.5V per battery. Please contact me so that we can further discuss on the details. Looking forward to hearing from you. Regards.

Hi- first we need DC to AC efficiency, but let’s consider 0.95. The needed battery power is :64000/0.95=67368.42 W. 4x battery banks wired in series with 32x batteries in each battery bank with 12v 210AH batteries for a 64kw load , seems to much !!!!! If we take the voltage of each battery bank, nominal voltage will be :12*32=384 Vdc, in series means we have 384*4=1536Vdc!!!!!!! Maybe you mean parallel configuration. In this case we have : 67368.42/4= 16 842.10 w/ string of 32. So we have 526.315 W/ block. All we need is only to know the battery reference or brand to see the table of constant power discharge with end of discharge voltage to find the run time. For full theory and excel file demonstration, please communicate me the mail address. Best regards
