The most important thing is to fill your needs and it doesn't matter what it takes to do it. The person that requires more features on a expensive controller has nothing more than the one that can get away with a ebay special. Each has a system that takes care of them and that's all that matters.

I think you can see by now the inexpensive portable are a good way to get started. To truly design a system requires a lot more than slapping some parts together. The portable will give you power now while you figure it all out. Believe me that one trip seeing how the solar deals with your needs, in your conditions will make you see these discussions differently. Use it for a season and give yourself time to understand more and you will tell us what will fill your needs. I'm on my second season and I'm getting there.
