Re: Inverter drains batteries

We do like Don does - use a little 200W inverter to power the TV. We just hard wire this into the DC system on a breaker labeled "TV", and turn it on/off as needed just like any other DC circuit.

These inverters are pretty efficient for the small current they need to provide. Our 28" Smart TV powering a connected hard drive and its wifi only draws 3A through the inverter. Any invert inefficiencies are in the milliamp range, and if once can't spare 1Ah for 10hrs of TV time, then one probably shouldn't be using a TV at all.

The problem with 12V TV's besides high price and weight, is that they just can't compare to the 120V offerings. Today's 120V TV's are available in unlimited sizes (although it is getting difficult to find them under 24"), will wirelessly stream off the internet or computing device, have a built-in media hub, connect to our on-board media router, take a USB hard drive full of movies, and several other useful features. Our 28" does all the above and only cost $120.
