HI Mike! I already posted this question on your Facebook RVelectricity page, however, I'm getting conflicting answers so thought I'd reach out to you for your expertise and advice. Some are saying there's a problem while others are saying this is normal and not a problem! Here it is...

We have a brand new pop up trailer with solar, lithium batteries and an inverter for those times when we need AC power. When I was doing our check out, I used one of those simple outlet test plugs and found that all of the outlets showed an "Open Ground" when running off the batteries and inverter. We then hooked up the trailer to shore power, 30amp connection, retested the outlets and all showed good. The salesman, of course, said this was "standard", but I'm not convinced. Is this something I need to be concerned with? If so, what do I need to do to "fix" it?

Thank you in advance for your help!
