Let me know, I can get a discount through the company I work for, but do not know if it will make up for the shipping. They are not terribly expensive, I think around 130.00 bucks. They tell you the voltage of the battery, the condition of the battery, the solar charge coming in from the panel and the draw the electrical is under, plus it has a shut off. Automaticly shuts off at 11.9. Unfortunately they do not restart, but allow charging while off. I ran some Outback units, but for the money these things are top notch.
