I have an inverter in my motorhome and wonder about using it to power the 240v tv & satellite for a couple of hours in the evening when not hooked up to mains electric.
Usage of power might be: 1 light,TV & satelite receiver and occasional waterpump. To fill the kettle & flush the loo.
Any comments anyone

What is it rated at wattage wise???, most of my friends and me included run everything on 12 volts, ie tv. satellite receiver, that way you could run the tv for hours, I have 2 leisure batteries 100 amp each and my wife watches tv from 6pm till midnight, no problem, although she does limit herself in winter when the solar panels are not charging the batteries aw well as in summer

Inverter is probably not the best solution, better to use a TV and Satellite receiver that can run on 12v DC direct.

Of course if you have Sky that could be an issue, unless you have got a Sky Mini-Box aka Pace Javelin 2000, but that is only SD and no PVR of course.

If you do choose to run the inverter, I would be using a Pure Sign Wave model, especially for electronic devices.

Having said that I did use to power a SD Sky box receiver only no PVR from a cheapy 150watt inverter and that worked fine.

My 18" LED TV is 240v only & takes 1.3a from the battery via my pure sine wave inverter. It helps if you turn down the backlight and bright ness settings

In approx 35 years of motorcaravanning, I have never had a TV, computer etc in any of my vans. I have all these things at home, but I like to get away from them at times!

However, from an electrical point of view, I would agree with Francais - use 12V devices or a pure sine wave inverter. I'll manage fine without.

Thanks for all your responses.
If I was starting from scratch I would, of course, have bought 12v equipment. However,the van came with 240v tv & sat sysrem plus an onboard inverter fitted.   
fleck2 seems to have best got the gist of what I was seeking. Mind you. I haven't a clue what a 'pure sine wave inverter' is. Just going to look it up now. I bet I get a response to this comment before I've 'googled' pure sine wave inverter

A good inverter is very handy to have, try finding 12v hair clippers or 12v hair straightners. Gertrude wouldn't be able to come with me if the straightners didn't work 😁

On another forum thread I did ask about adaptors for plugging 240v appliance into 12v socket.

Just to confuse the issue, the term 'sine wave' is sometimes misused. There are various inverters that produce a 'modified sine wave'. Hard to describe without a diagram, but in basic terms, a sine wave is a smooth curve, while a modified one is like a set of steps.

For things like incandescent lights and fans, this isn't a problem although sometimes it makes them hum or buzz.
Things like TV's, laptops etc.. may be more sensitive.

Personally, I'm happy to escape from these things and have a bit of peace & quiet.
