I’ve gotten this when I tried to series 12v panels (12v 100w x 4) to my ac180. I just got a an elite 400 and it looks like I may run into the same issue with the new panels I’m setting up (12v 200w x 4). I should theoretically be well under the 60v limit to both machines but I’m not having luck here. Is there a device or workaround I can make use of to maximize my solar input? Parralelling caps me out at 200w actual.
Thanks in advance for any assistance you can send my way!
