i installed a 1500 watt next to my batteries (you want the least loss possible on the low voltage side) then ran romex to an outlet next to each T.V. I split the stock outlet, one is "house" 120 volt the other is "inverter". I installed a remote switch inside my fuse panel that turns the inverter on/off via a relay at the inverter (some have the capability of a remote but cost more). Works great, runs two T.V.'s plus satellite and/or DVD. Inverter is from Harbor freight. Hardest part is running the romex but I was able to follow the OEM wiring and fish it through
