40 amp mppt controller so far, the quality of this controller far exceeds the price. Well built heavy unit, good fit and finish, nice clicky buttons.
You need the MT50 to set the parameters. It's a little janky. Soft cheap buttons, awkward menus, so so display, but it works and gives you volts, amps, Watts, and watt/hours from the panels to the controller, and from the controller to the battery.
I'm using it on a very small system right now, and I have plenty of room to grow without upgrading the charge controller.
I would buy another. Seller shipped super fast.
This is a great product and was very easy to install. In my application the MT50 monitor was a major factor in the buying decision because I have a small panel in the horse trailer I am building and this fit in it very nicely. Low voltage shown on monitor is due to trailer being inside. The panel is temporary to make sure I like the layout.
Added to my current solar array because the prior one is working perfectly and I hope this second one will be as reliable.
Works really good... just wish it would handle more panels...
