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.
