Q	Why when I hook up my 5 24v solar panels after I connect the batteries to the charger and it started smoking why
A	ARE YOUR PANELS IN PARALLEL OR SERIES? IF IN SERIES IT IS TOO MUCH VOLTAGE. 5 X 24 = 120 VOLTS, IN PARALLEL IT WOULD BE THE 24 VOLT YOU NEED, LOOK AT THE CIRCUIT BOARD AND SEE WHAT WAS SMOKING. YOU MAY BE ABLE TO REPLACE THAT PART AND GET IT TO WORK BUT I AM AFRAID YOU ARE STUCK WITH A DEAD CONTROLLER. IT WILL NOT BE REPLACED IF YOU DID NOT FOLLOW THE DIRECTIONS IN THE INSTALLING OF IT.. CONTACT THE SELLER TO SEE WHAT TO DO see less

Just received it today so can't give an honest opinion although it looks to be what is advertised. Only thing I didn't like is that there is no literature with it

Good entry level solar charge controller. I have two of these in different amperage ratings, one for boat and one for home, and both work well. Seems to have a standard user interface with most of the Chinese units. Easy to use, would buy again.

Comment

Right now I got it temporarily hooked up to three panels and this is the only charge controller that I found that will hold up to 1300 w which would be five of my 260 watt panels and they're 37 volts each so I can't them in series together so I just parallel them all in so that they're just the 37 volts going to it but so far it's working pretty good will finish checking it out whenever I get the rest of my panels and get them mounted and I'll let you know and I also got it at a pretty good price considering what everybody else wants I would have had to buy two of the other ones to get what this one will do

I ordered the 40A controller then realized I would need the 60A instead. I'm so happy they had both. This will also let me know what my status is continuously which is very important.

Fast shipping from Germany, controller cool, works well even with two panels in series and Aku 12V ie in 12V system can connect panels in series-parallel. Dimensions to disagree 280x190x85 and the same controller is even smaller. Inside there are two powerful coil. MPPT is not such again fast, when bezchmurnej weather burdens panels up to 60V-52V at serial combined. Assembly components made in average Voltage end charging and hold can be set what it wants programming is very simple. Very useful is able to set cutin load when the wants and at what voltage has to enclose and off, there is also a breaker zmierzchowy and temperature sensor. General good regulator, inexpensive compared with others. Recommend.
