My new solar panel arrived today. Zamp 200W external panel with controller. The controller comes wired with the male SAE plug so it plugs right in to the female plug on the rear wall of my Grandby. Smart controller runs itself - just choose your battery type and go. The default setting is AGM. I am now officially off the grid.
