This controller has more features than advertised and gets a little warm when running at 90% of rated power. I don't have to move to check the settings because the remote monitor is next to me. It was a great purchase.
Pros
RS485 dual port (RJ45 connector), supports up to 8 parallel charging to expand the system and meet different monitoring needs, so it is widely used for various applications such as solar vans, home systems, field monitoring, etc.
