I've been using this for about a month now for my small 100 watt solar system in the garden. So far, so good. It worked consistently and kept my battery charged. LED indicators are ok. A little more information would be great, but I knew what I was getting. I am planning to install a reverse amp hour meter to track charge/discharge status. The case looks a bit wobbly. The connections are fine, but the wires definitely need some loosening after they come out of the controller. This is my first solar project so I'm kind of inventing it as I go. The inverter is ok for the price.
