This is an advanced version of a Power Flower or EE flower. It is basically multiple flowers set up with a retriever to collect EMC, personally I use diamonds as the fuel source, but dark matter or red matter can be used. I would suggest using diamond for MK1, DM for MK2, and RM for MK3.
I suggest using thermopiles to power the retriever so it can run 24/7. Also if your setup is massive, change the fuel to red matter and add more to the retriever. You can suck up to a maximum of 45 stacks of red matter within a second with one retriever, granted you have enough collectors. 8 thermal piles can keep the charge. I use the solar just to speed up the initial charge.
Below, there is a gallery that will help you better understand how this setup works.
