Once you make the decision on a 12 volt inverter you really are locked into 12 volt. Zwy's system makes sense. You are asking questions but don't want to listen jungry. Sorry to be harsh about it but you have made two bad impulse purchases in a row on the Renogy equipment. Also, your wfco is not going to charge a DIY pack with the flexibility you will want. Zwy now has a system leagues ahead of you and has spent less money, less complicated, less space and less weight. You have ignored everyone's advise here.
