I'm not sure who makes this or where it's made, but my guess would be China. I can only guess because it came with absolutely no documentation or instructions in a plain brown box. That said, it's fairly simple to hook up and it does seem to work as a basic charging regulator. The display/control module is difficult to read since the LCD display doesn't seem to have any contrast adjustment, or if it does I haven't found out how to adjust it. There are four buttons on the control module but all I've been able to do with them so far is toggle between monitoring the battery pack voltage and monitoring the solar panel voltage. It looks like it should allow a choice of battery type and capacity, but I haven't been able to change that from where it's defaulted at. I wouldn't buy this again, and wouldn't recoommend it for anyone who seriously needs a good charge controller.
