Not sure if this will help but I am building a system similar to what you seem interested in check it out in the show and tell section.scottvanv is the fella I'm watching. He's further along than me. I think he's using (2) LV6548s and (32) 455W panels. I don't know what he's using for batteries. I'd like more info on his build. I need to make a correction on the well pump kit. It is from RPS solar pumps.
