Just starting to play with solar.
I installed a inverter to power a house receptacle. I used a double-pole double-throw switch so if needed i could switch back to house main. The switch is used to redirect hot and, neutral only, I used the existing earth ground. Now when i test the circuit my tester shows a open ground when i use inverter power. I can switch back to house main and the circuit will test correct.
Why?
