You will need to bear in mind that something like a 22" TV will use a lot of power. You're going to need a very good domestic battery bank for something like that. I have a 19" set which I bought from John Lewis (sadly now discontinued) and although it was supplied with a mains adaptor it was a 12v set so all I had to do was buy a regulated 12v power supply for it. Nothing much you can do about Sky HD, it has to be run on 240v which is why I have reluctantly stuck with ordinary Sky through a 12v box

we have a 20" flat screen tv and have a freesat box both up for hd and all runs ok as for power the more you use the more you run your engine and we only use a inverter for 240 volts, it will all be down to trial and error

thanks mick is your inverter a large kw 2.5 or 3.kw or smaller mike.

mine is 3kw but if you check you tele you will find it is around 50watt so for a tele either will be enough

I bought a camping 12 volt satelite system from Maplins for £90.00, it was a complete kit with dish, receiver and remote control and performed well last season. I agree it is hard to find 12 volt kit. Asda did have some 12 volt TV/DVD combinations before Christmas, I think they were 16 inch and 22 inch versions starting at £100.00
