It looks like you got your answer, you will have to up your controller.
I really just want to comment on your WindyNation system. I bought the 100watt system and added a second 100watt panel. It is doing well we have camped twice since I installed the system and in the 20 days we have been camping we have not needed to run the genny. We have two interstate GC1 batteries from costco that are about 2 years old.
We are moderate in power usage and run the 32 inch tv and the BluRay about 3.5 hours a night. The system is really worth it and I am very happy.b
