hi guys i'm looking to buy a small solar grid-tie kit for school. i need to connect it to a battery so it will store the energy that created during the day and during night to use it. if the battery will run out of power ,it will pull some from the electrical grid and the load wont "feel it". does someone knows where can i buy one ?

You will need four parts of this kit :
1.solar panels
2.controller
3.converter
4.batteries
principle figure will be this

1.solar panel --------->2.controller -----+---->4.batteries -------->DC device
                                                            ↑
                                                            |
power grid --------->3.converter --------

At day time ,solar panel output electricity feedback to the converter ,then the converter will cut the power grid out .
