Good luck getting in touch with Netgain controls... I have been trying for almost a year... very poor customer support. I eventually purchased another controller.
I do not believe that these controllers are easily upgradable. You will more than likely need to get a unit that is rated for the voltage that you are using. I went through the same thing with my old Curtis controller.. I had to buy a 1231c to use higher voltage.
