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.
