    I can connect the input to just about any energy producing device and it seems to charge. I have mine on a wind generator. It is allot smaller and lighter than I anticipated. The quality seems a bit sub par, maybe it is the thin plastic, not that it bothers me. I am happy at how well it works and the price is fantastic, I got 20 amp which is (20A x 12V) =240 Watt. That is a lot of solar panel in my opinion. You don't want to run it near maximum for extended periods though, if you need bigger you can buy more than one at that price. The screws are a little small for my hardware, you don't need any large wires for this type of application though. The load screws are perfect for small lights or something you may want to have running all the time, it will cut out when the battery gets below a certain amount it seems. However it is not intended to run with a big load.

    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!

    Still testing it, haven,t had alot of sun yet. The sun that have had, it seems to maintain a 12v battery, that I have hooked up to it, 13.6v during the daytime, and holds about 12.9 at night. the display work, to show the status. So yes, its worth it.

    Small, light, does exactly what I asked it to. As others have stated, make sure to plug the battery bank in first. I like it enough that I'm buying another after frying my first one that way.

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