How can I make my solar grid feed system into a power storage system?

There is a regular power cut off in my area. This is due to some greedy power company. I want to go offline from these companies and make my own power storage system. I would only need to run a laptop, television and some lights. I even have small backup generator. How can I make my solar grid feed system into a power storage system? I would really appreciate your useful opinion regarding this. I hope to hear at the earliest from your side. Thanks.
