Our trailers come standard with three-way charging systems. The first is direct plug-in to 208-240VAC. The second is the included 230VAC 5.5KW generator. And last, but by no means least, is the roofline solar panel system. With 500W of solar panel power and two 210Ah batteries, come hell or high water your system is always ready to Deploy! (...Hey, that would make a great name!)
