I upgraded to a 30A tracker, and have this 10A tracker I am not using. The fan was getting a bit noisy and was still covered under warranty so I have the new fan here...but haven't installed it yet. Pop the new fan in and it's a perfectly working system. Used it for about a year with my Harbor Freight panels. I was going to list on ebay but I figured I might get more bites here. Anyone interested? PM me.
