Bought this one in May 2010, and is working properly on my solar energy system, charging the batteries properly, I saw many bad reviews about this charger controller, but sometimes people do not realize that you need some technical advice to connect this charger and do not mess up with the connections, inverting the polarity on the batteries to connect to the charger. Many people that want go solar are DIY and mostly do not have skills with eletricity, this is working fine for me 400 watts solar panels charging everyday my batteries and I still can see the current flowing to the panels. If you want go solar ( please ) take some time understanding the principles of

electricity and electronics.

I got the thing home and hooked it up and it started to charge and then shuts itself off after 2-3seconds..

tried different batteries and solar panels and Nothing.. I don't want to waist more money trying to send it back and get a new (janky) one.. so I bought an HQRP controller that does circles around this thing..

needless to say this Wagan solar charger is in the garbage... maybe it will work for you but it didn't work for me.. buy something better and be happy with your purchase.

The unit did not function when it arrived, and when I looked into the return policy I found that the company will not pay for return shipping on any replacement in the warranty period. I am returning and selecting a different manufacturer so that if I do need warranty service I won't be stuck with a bill shipping the unit to them and then with the bill for sending a replacement back to me.

I have only had the regulator a little over a year and it already has stopped working. I don't know if I will buy another of this brand because of the short life span.

I've had this solar charge controller in operation for six months with no problems. The best feature is the voltage/current switch. It shows the charging current as well as the charging voltage. You no longer have to guess how your panels are performing. The only con is that there is no low battery voltage protection. Not a problem if your DC to AC converter has this over discharge protection circuit as mine does. I have two 80 watt panels charging two 12v deep cycle wet cell batteries at approx. 18v and 9amps during peak sun. At a 400 watt and 30 amp max, I still have room to grow! I'm hooked on harvesting the sun. I'm sure the payback is way out there somewhere, but my real interest is in having electricity when the power goes down. The price is right and it does the job with some nice bells and whistles...
