The Solar stopped working on our second time using our 2018 SS Agile. We took it to a local dealer for warranty repair. While at the dealer RT went out of business and the dealer said that without RT support they could not repair the unit. So I picked it up to do the repair myself.
Thank you to KS2, the company that designed and built the system or RT, I was able to accomplish this task. They programmed a new solar control and shipped it to me.
I Installed it yesterday and everything is back up and running. Yay.
