The most important thing is to enjoy your life - to be happy - its all that matters.
Itís automatic and takes 2 minutes to setup, no faffing about finding satellites just press one button and job done.
So thatís the reason I have a tv and satellite system, but everyone to their own. Some like me like tv others hate it.
I have a Sky HD box in mine running from a good quality modified sine wave inverter without any issues for many years.
1. You do not need an expensive pure sine wave inverter to run a sky box, which only takes 30w max. Output voltage must be around 230v otherwise internal ky box PSU with thermal out. Many cheap inverters have poor set up and can be around 260v at low load but 230v at nominal load.
2. The Sky HD box will happily run from a good quality (not cheapey Chinac knock off) inverter without issue as it has its own power supply regulation board inside.
3. You cannot hack the Sky HD box and feed it on 12v inside as the PSU outputs differing voltages for parts of the board 3.3v, +5v , 0v, -5v and 12v from memory.
It is highly liklely that your inverter is the source of problem but any decent 300 to 600w modified sine wave inveter will run your Sk HD box without issue
If you only want to power a 30 watt load, buy a 100 watt inverter, or smaller. That way the inverter will be in its comfort zone.
A genuine PSW will be notably more expensive than a modified sine wave inverter due to the components that are required. The bigger the inverter capacity the bigger the price difference of course. But when it comes to the smallest inverters, the extra cost of buying a Pure Sine Wave inverter has much less impact as neither are massively priced.
I am a bit of a Victron fan as I have never bought anything from them which has not worked well. I have checked the output of the Victron Inverters I have and the wave form is a perfect sinewave. This is not that common even with PSW inverters unless you get the best quality ones.
The cheapest Victron PSW inverter is a 150W Inverter and can be bought for under £70. Admittedly this is a fair bit more that a basic MSW inverter (I bought one from Amazon last week - £22 for a 500W one. Bought solely on price for a specific project where quality didn't matter). So three times the price but .... in real terms, under £50 more for a far far better product.
Now does the no-load current matter? if you switch it on specifically when you want to use the sky box and off again afterwards, not really, but it is true to say that the smaller the inverter wattage is, the more efficient it will typically be running low power devices such as a Sky box, so Hairydogs point (quoted below) I would go along with. It can be tempting to buy a much more powerful inverter then is really needed 'just in case' for the future, but it really is counter-productive in terms of power usage.
As an aside, why do people question WHY someone wants to run a Sky Box in their Motorhome? OK, debate the best way to provide power to it, but not why they want to do so.
One mans meat etc .....

You can run the sky apps on a laptop/tablet/smartphone to get the premium channels I donít know if that is any use to you?
