I recently started getting a rated voltage error on the MT-50 screen. I think my 1k solar array is exceeding the 100v max voltage with the 90degree temps we been having. My question is can I hook up another 4210 AN to the existing one in parallel to make it a 80A controller? I did buy Will's e-book, but although he mentions in his video on the 24V system you can hook them up together, it's not discussed in the book. I'm not sure how to do it and don't want to experiment and fry my charge controllers. I sure would appreciate someone sharing their knowledge with a 67 yr old newbie. Thanks
