Hi, I've recently purchased a SureSine Classic 300W inverter that will be installed in a VERY small teardrop trailer (https://roadtoadcampers.com/abode.htm). The inverter will be used to power a single dedicated AC outlet that will be isolated from the shore-power AC system and which will only be used to charge a laptop computer. I'm not sure what to do with the "earth ground" on the DC side of the inverter since there is no connection with the ground while--the trailer sits on rubber wheels. I could connect to the aluminum trailer, but this is not an earth ground.
Do you have any recommendations for how I should install this inverter? Can I (gasp!) just not use the earth ground in this application?
