  1. Well built heavy unit review by Frederick Maskeroni on 1/11/2018

    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.

  2. Great monitor makes this a great product. review by Tom in Montana on 8/26/2017

    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.

  3. A second purchase. Not a replacement for the old one, but an additional one. review by BTC on 7/2/2017

    Added to my current solar array because the prior one is working perfectly and I hope this second one will be as reliable.

  4. Good solar controller review by MadMods4u on 8/24/2016

    Works really good... just wish it would handle more panels...
