I have had one of these units for almost two years. Soon after I installed it I was noticing that some mornings it just didnt track right. It would end up putting little load on the panels even though there was reasonable energy available.
On the Outback forums they first denied that such a problem existed. Eventually, after enough people complained, they said that a firmware upgrade was available. But, to get one, it is necessary to send the complete unit back to the factory. As I am in Nicaragua, that totally sucks.
Well, the unit finally just failed. It will be replaced with a Xantrex or Morningstar units. I have used products from both those vendors and never had problems.
