Hi  
I want to make sure I understand it correctly  
I can connect two power supplies to the board (like Solar & batteries) **as addition** to the main supply  
Once main supply is not available it will switch to battery till it is almost empty and then safe shutdown will occur?  
All above is default or do I need to configure some how?
