I have owned this very same Inverter since the fall of 2012, and still have it in use. When I began creating my solar system, I wanted something that could be used to power the Product Listed items (i.e... TV, Lights, etc..). Also, I needed something that could handle the power requirements of basic medical equipment that I use ~ Nebulizer Machine for breathing treatments, etc... I like that this item turns itself off when it reads that my deep cycle batteries are getting low, so as to prevent causing them any damage by draining them dry. After having 1st hand experience in using this inverter since the fall of 2012 in my solar system, I can HIGHLY RECOMMEND IT! Follow the recommended setup provided by Cobra and you will have a nice unit that last.
