It's not so much the TV, ours is actually a 12v (which just occurred to me as we generally just use it on mains) but the Sky Q box would be another drain. One of these days I'll stick my monitor on it to see what it actually uses power-wise.
I've also considered getting a second solar panel (we have a 100W roof-mounted) along with a second battery, but on our 'van the battery is actually centre-mounted under the floor so it'd be difficult to sensibly wire a second battery in with short enough cables etc. but not impossible.
Personally I'm not overly bothered with mains for shorter periods. I managed to squeeze in a quick brew from the Nespresso during one of the brief returns of power

(I have a stove-top mocca pot for off-grid use generally but don't have the coffee with me so wasn't expecting to be off-grid).
In all honesty Big Brother makes my skin crawl so I'm certainly appreciating the power cut right now!
As for the generator, I've half-convinced myself of a number of additional uses for one, including semi-emergency use at home during a longer power-cut, so I have a sneaky feeling it's on the cards sooner or later...
