    I managed to cook my controller for my solar system on my vintage camper. This was a far superior replacement and I am happy with it. The terminals are a good size (not too small) and easy access. Great price too.

    Very sime and made cheap but extremely cost effective for a small project. I have had a couple and they work great with a 100 watt panel to keep my RV battery charged in storage.

    It lacks some convenience features (such as showing you precise battery voltage/capacity or solar panel output). However, it's working great and hasn't failed me so far.

    So far it is handling one 225watt panel to a 24volt battery array. The six screws for fastening wires are so small that I had to reduce #6 wire to #10 wire to fit them in. This was a test of a very low prIced voltage controller, and it seems to be doing the job.

    20 amps for about ten bucks! This thing works and it is not expensive. I use it for my boat when I am gone for a long time. Love the 24v option too.

    Works as advertised. Can't really say more. I had the 10A version, and it burned after 3 months (stopped charging battery).

    So far, so good! Tested controller on a small solar pump project using a 10 watt panel and small, automotive sealed battery. The pump will run directly off of the panel, but the charge controller and battery extends the run time. Worked like a champ! The instructions are not written very well, but they make sense, if you read them carefully. For people new to the subject, recommend you search the internet for how solar charge controllers work and what the input and output terminals are for. Especially, the "Load" terminals. If you follow the connection sequence in the instructions, the controller works, as advertised. This product is well made. Some reviewers may have tightened the terminal screws too tightly. I had no problems with connections or operation. It's too early to see how long the unit will last, but I am impressed with the quality for the price!

    This product works well. Better than my old shunt solar regulator. It charges my flooded lead acid batteries to 14.4V then shuts down. It resumes charging as need to keep the charge topped off. I haven't put more than 3 amps into it because of tree shade, but it doesn't even get warm during operation. We will see how well it works when I put ten amps through it this fall..
