I installed a new TV in the bedroom of our Georgetown. Since it was a new TV purchase, I selected a model with low power consumption. This is easier to do now that there are many LED/LCD models to choose from. The older LCD TVs using cold cathode tubes to back light the screen consume much more power. The new TV is a 24" LG model that only uses 35 watts, and has power saving features available to use even less power, although with reduced picture quality.
I used a commercial grade Samlex 300 watt pure sine wave inverter. The inverter needs to be located as close as possible, but not in the same compartment as the batteries. Use heavy cables and keep the battery cables as short as possible to the inverter to minimize voltage drop. After the inverter converts the 12 volts DC to 110 volts AC, a longer 110 volt power cable can be run to the TV.
Just as with a generator, you want to select an inverter based on your power needs. It makes little sense to use a 2500 watt inverter to power a 35 watt LCD TV.
I installed dedicated electric outlets for the new TV and a few other small devices (laptop, AA battery chargers, etc.) in the Georgetown. Everything has been installed for over 1 year, with no problems. We find having the additional inverter supplied power outlets to be very convenient for various small needs, and save using the generator for big loads like the microwave oven and roof air conditioners.
