I bought one of these units, designed to be used in a concealed, ventilated location. It handles a maximum of 15A output with PV voltages up to 75V, and has lots of operational features. It has 3 cycle charging, with an additional auto equalization cycle if you select that mode. It works with all types of coach batteries, can output data logging info, and be remotely programmed for most parameters. It has LEDs to indicate state-of-charge, charge mode, and error conditions, and you can purchase a small remote LCD data panel if you wish more info on display.
It is quite compact, seems very solid and well-engineered, and I have observed it automatically cycling through all three modes in a day's charging. Lots of info, data, and free software available on the website for anyone interested in engineering it into their system.
