Roof Solar-Inverter shows 'No Ground'

Goal: Power from inverter to main trailer. No Air Conditioner or microwave from solar.
Plan: Renogy 200W kit->MC4 to roof connectors->10ga wire->MPPT Charge Controller w fuse in basement->4x6volt Batteries-->3000Watt Inverter->12ga Romex to rear plug of trailer by Shore power plugin. Also have battery monitor plus remote switch for inverter.

Issue: Inverter was grounded to frame, but the 3-prong outlet tester shows 'Open Ground'. Jayco owner's manual says to NOT use Open Ground source.

I believe olddude1970 is correct. Our local Scout Camp had a solar inverter installed to operate riffle range lights. Would not work. I was volunteering at camp and they asked me to look at it. No earth ground. Drove a ground rod, attached copper conductor between rod and inverter and all was good. Just my $.02
