Inverter

What size invertor would I need for a 24" tv plus satalite box?

If you look at the back of the TV and sat box they should tell you what power they require, is that all you would want to run off the inverter.

Yes it is. if want to use hairdryer presumably I could just unplug tv and use ??
LED TV 40 watts
Skybox 25 watts
Does this help?

For those two devices you could use a small 150 watt inverter, which is small enough to use a cigarette-lighter socket if you don't want to wire it directly to the battery. Anything bigger than 150 watts needs to be wired to the battery, via a suitable fuse.

You need to be aware of just how much power a heating device like a hairdryer or kettle takes. In contrast to the 65W total of your TV setup, a hairdryer takes 800W minimum, and can be higher. A microwave needs over 1000W. A standard domestic kettle is 2200W, and a low power one is 1000W.

There is a downside to larger high power inverters, in that they drain power even when nothing is plugged in. They need to be switched off when not actually being used.

I would get a small 150W Pure Sine Wave inverter to power the TV setup. A bigger inverter requires more thought, and possibly more/bigger batteries and/or solar.
