If I create a grid tied system, and find the right optimizers that would work for a day time black out, would this be more efficient or able to work in conjunction with a backup power source for emergencies. What is cheaper? How can I both store power for a night time black out for instance, while having the the appropriate system for a day time black out. Can I do everything?
Thirdly, what about time of use, if I am able to store to batteries can I get power back to the grid from my batteries that I generate at night to count as credits back at peak time of use?
I just want to know, with TOU, can I buy batteries, get the power to grid... Still get same rate because I pay for power?
