Spot on about the gatekeeping. I've noticed it loads on these forums—folk seem to think off-grid is this binary thing when it's really a spectrum.
My setup's probably the middle ground: shepherds' hut with solar + battery for most of the year, but I'm honest that I'm not truly independent. I've got a grid connection for winter top-ups and genuinely bad weather. Does that count? Some would say no, which is daft.
What @BlownFuse mentioned about understanding your load is crucial though. I spent weeks just monitoring what I actually use before I sized anything. Turns out my biggest drain was a dodgy fridge that I thought was efficient—swapped it out and suddenly the maths made sense.
The motorhome brigade especially get grief, but they're often more disciplined about consumption than folk in brick houses. Less space means you have to be intentional.
Think the real question should be: "Are you actively managing your energy rather than just consuming whatever's available?" That's the actual shift in mindset, regardless of whether you're 100% grid-independent or running a hybrid setup.
