Simple set up easy to use

Have 7 of them working for the last 3 years and still going strong, worth the money. I bought 4 extra for back up and there still in the box.

Works great, especially considering the price

For the price, these are excellent . I have had one in use for about 18 months, and another in use for about 9 months Both have worked flawlessly. I bought two more for backups, or for new projects, but haven't needed to install them yet But I tested them before I put them in storage and they worked properly. I wish that these had been available back when I spent multiple hundreds of dollars on big-name 'professional' type charge controllers.
