Can you have multiple inverters powering your entertainment gear,
without causing problems.

I am thinking of having a flat panel TV powered by one inverter, and
the DVD/PC on another, and my Raymarine E-80 connected to the TV as
well.

I am concerned that the ground between the devices won't be a the same
voltage, and I will cause a current to run through the ground wire, and
damage equipment. I am hoping I am wrong, and there will be no issue.

Anyone have experience here ?
