What is the name of a device that would send input current out to my home and maybe upstream from a power device?
You're looking for an inverter, and likely a transfer switch.  

Note that selling surplus power back to your utility is far from trivial.  There are contractual issues (not all utilities will pay you for the power), component issues (you need a meter that can handle the buy vs. sell rates), and safety considerations (power generated from the home and sent "upstream" may energize lines that are believed to be safe to touch by service personnel).
