Bill, I suggest calling the manufacturer of the controller. They will be able to provide you with the best info. Forrest River did say that they were making changes to the solar setups, but with the Covid supply issues, they changes they made may not be the ones they planed to make and they may have used more than one vendor and controller model.
Best of luck, Jeff

Hi Tom. I am going to post this but you might be able to answer so I wanted to message you. I just got a Cherokee Grey Wolf 18RR. It has the juice pack. Controller and panel say they are Waaree brand and I want to add another panel and battery. When I picked it up the salesman said you can plug and play another panel and keep the same controller. He said I could add either another 50W, a 90W, or a 140W panel. Not sure if he is correct because he also said it was a Zamp solar panel. I prefer to minimize cost so .... Does it have to be the same brand? Or? Has anybody done this without replacing the controller? Thanks in advance.
Bill
