I am having difficulty in understanding one control box which is used to charge the battery( www.kynix.com/Detail/204725/CR2032.html) using solar and wind energy as well as power the load at the same time. I have attached the picture below:  I understand the part of the wind turbine but what I don't understand is the part where it shows the positive terminal of solar panel, battery and load should be connected together. How can this work? since the battery is charging (connected to solar panel) as well as discharging (connected to load) at the same time? In my mind I was thinking the controller would be more like this the following,  Here you have separate connection point for each components which make sense to me but in my previous picture I don't understand. Can any one answer this for me? |

I have a wind gen and Solar set up. Where did this come from? What was the price for it. Is it 12 or 24 volt??
I may just get one.

In your 1st picture the common is the positive that is why all the commons/positives are wired together, the negative is not commen like in an car etc. Many controllers like in your 2nd picture are still having a positive commen, but it is internally wired inside the controller.
In other words, the negative is that controlled or switched wire, not the positive.
So care must be taken, not to wire any of the negative wires together at any point in your system if you have a cheaper controller like I have or like this controller is. Many out-of-state made controllers have a positive commen.
For example.
If I would hook my negative solar panel wire together with my negative battery terminal/wire, then the battery would charge as long as the sun is out regardless if the battery is full or not and such battery will be overcharged since the switching wire is the negative wire. But if the negative wires hooked together, the controller can not switch them, since those wires are not goining through the controller to be switched, those wires are bypassing the controller.
If you hook your system up, like in your first picture you are hooking it up correctly.
yes, the 3 yellow wires are 3-phase AC and the controller will convert the AC into DC. I am not sure if the controller is setup to apply the brake if the windmill is not used or if a storm is coming. Normally to apply the brake all 3 yellow wires are shorted, but you better search the net about this controller.
