GoSun Camp365 comes with two separate electrical systems: a 12-volt DC deep cycle marine battery and a 120-volt AC system. The 12-volt battery is installed under the floor and is charged by the tow vehicle during transit or via solar power. Your GoSun Camp365 comes with a standard SAE solar port where you can plug in solar panels. The 120-volt system can be connected to any standard 120 volt outlet via an extension cord and a 15AMP Male to 30AMP female plug adapter (extension cord and adapter sold separately). That’s the standard outlet you typically find in your living room or garage, or what RV Parks and campsites will often refer to as “Shore Power”. You can also plug this 120-volt set up into a portable generator. The 12-volt DC battery will also recharge when the 120-volt AC system is being powered.
