week 7 semester 2 - testing the circuit

After a few times correcting the coding error and circuit, its finally work the way i desire. here is the picture of the running circuit without renewable source yet.

VA = to indicate voltage in from the first source
VB = to indicate voltage in from the second source
VC = to indicate voltage in from the third source
VD = the amount of the supply or storage
Total = to indicate the voltage amount left in the storage
% of VD = percentage of the total amount in the storage
