If inverter input voltage drops from 12.8 VDC to 7 VDC just by connecting the inverter I would go measure the house battery bank voltage at the same time. If the battery bank reads 7 VDC then you have bad batteries. If it reads greater than 12.0 VDC then you have a bad connection to the inverter.

Just to be clear, connecting shore power doesn't change the voltage from the battery bank but it DOES change the voltage that is displayed across the input terminals for the inverter. When the inverter is not connected to the battery cables the voltage there is consistent.

I have pulled the batteries out, tested them and they are fine. I also checked the connections at both ends and they are good. I think there is an error inside the inverter.

How did you test them? Did you use a load tester? Did you check the battery bank voltage with a voltmeter when you had 7 VDC at the inverter?
