Okay great you guys. And thanks Joe Ham and Smokin. I understand the concept of a controller relay that could be activated at certain parameters and the fact that there is a limit to the current draw of that relay. Makes sense.
The problem was I had no idea that there was a feature like that...
Okay maybe I am not understanding what max load current is. I am connecting two panels in series and then the other two in series and I am going to connect both of the outputs to the 48 volt battery. (4 12 volts in series)
In the chart I posted it seems to show what I would consider normal...
Thanks for responding. I have four panels that are rated 330 watts and the output voltage is 39-40. I planed on putting two in series for around 80 volts to each charge controller. But the panels put out 8 amps in bright sun and according to the data sheet that would blow out the 100/20 48.
This seems like an easy question but I think I have been scammed. I bought two of these and when I was looking over the text on the box I noticed a huge problem.
I have checked the download data sheet on this and it confirms what I think.
The official name of the controller is 100/20 48. The...
