240v tv through inverter

[lars04]

Just wanted to see how fast a normal tv through a inverter in my patrol would drain my aux battery. Can anybody tell me this?
Cheers

Depends on the type & size of TV. You need to check the power consumption on the TV’s label. It will be in watts. Divide the number of watts by the battery voltage & it will give you the current it will draw from the battery in amp hours (Ah).

eg. Say tv is rated at 60 watts. Divide 60 by 12(volts) = 5 Ah (i.e. 5amps for 1 hour)

If you have a 100Ah battery you have a useable capacity of about 50 Ah before the battery is discharged below a level which will shorten the life of the battery considerably.

So ..... if you running nothing else, you could happily run your 60 watt Tv for 10 hours. Of course you will likely be running other stuff too & need to have an idea of how much current they draw too.

Bottom line is that a smaller Tv’s will use less than big Tv’s, & newer flat panel LED types use the least. If you have one which runs direct off 12v it will use less than a 240v one which will also need an inverter to run it. Inverters themselves will use some of the battery’s capacity. When trying to work out how much power will be drawn from your batteries by an inverter, a very rough but easy rule of thumb is for every 100w at 240v, you can expect the inverter to draw about 10amps at 12v from your batteries.

If you use a satellite dish to get your signal you also have to power the Satellite receiver.

Good post Cuppa, we were given a 12v tv and it's only small but more then perfect to shut the kids up on camp to watch a movie before bed.

My old man (and Roofy) curse us for doing this but ?

They are cheap to buy mate so if it's a possible necessity in your lifestyle then buy a compatible tv as the old Rank Arena won't cut it

Was camped up at Angusvale (Mitchell River National Park) in our bus one easter. Kid walks past, stops & asks what the satellite dish was. “For the Tv” I said. Straight out he responded “That’s not proper camping .... me dad said”. I smiled & asked him if he had a TV at home. “Yeah, course” he said. “Well this is our home so do you reckon you’re dad would approve”. “Yeah” he said with gusto & a big grin.
