Hey all. Ok i know everything just ask my 2 exwifes. I am well beyond my abilities so i hired a company to set up my solar. However they wont build my battery bank. I am told by someone with 20yr in the field. He said the way i need to wire my bank is in 3 banks of 16 at 48v at 300ah. I do believe him however i want to dot my i and cross my t. He said that ah is no concern and 300ah is the only way to keep my 48v banks. I am confused i thought parallel did not effect v so why will putting my 16sbank at 48v diminish when i hook up the parallel part. Once i have my series hooked up at 48v why will the parallel lower my v? I will have 15kw in the bank configuration of 16s in series at 48v(x3) but only have 300ah because i did not put any parallel connections. I am so confused, i thought ah is longevity.
