give 20% (of total power demand) for allowances due to losses. The battery can be discharged to 50% and inverter efficiency is 80%.I would like to use 12V, 200Ah batteries. I am told by an expert that I need 8 batteries. Is this true. And if so, please help me calculate. Please contact: <mailmekyle@gmail.com> Thank you.
I am terribly sorry. I missed the detail. The full details: 8 machines of 120W to run for 5 hours, 2 machines of 240W to run for 6 hours. 20% allowance for losses. Total power consumption is calculated as 9216W. Give 20% (of total power demand) for allowances due to losses.

Hi there. This looks crazy, but please help me go through the steps. Total Wh=9216. then due to battery discharge %age being 20%, coversion efficiency being 80%, then 9216/(200*12*0.8*0.5)=9.6 batteries. Where is the discepancy? This is getting to my head!
