Mate, the real question is whether you're running single-phase or three-phase — because that changes everything about your earth reference point.

Mate, the inrush is the real problem, not the run watts. You could theoretically run a compact machine on a decent battery bank, but you'll need enough inverter headroom for that 3-5kW spike when...

Inrush is definitely the killer here. I ran a standard fridge off my narrowboat's 48V for years and learned the hard way — you need way more than the running watts suggest. Grab a 3000W minimum...

Cheers for the detailed breakdown — this is exactly the sort of thing I've been worried about with my tiny house setup.

The modular angle is exactly right for boats—spatial constraints force you to think vertically and in layers rather than spreading everything across a massive battery bank.

Interesting thread. I've got a mix of Victron kit backing my array rather than focusing on panel brand alone — though I will say the panel choice matters less than people think when you're dealing...

Running PWM on my garden office setup and honestly it's fine for what I've got—small 400W array, 48V battery bank.

The van's ideal for this. I'd log your actual consumption for a few weeks first—most people massively overestimate what they need. Once you've got real numbers, size your battery accordingly.

Spot on @OldSailor. The "ask forgiveness not permission" approach is how people end up with enforcement notices, especially if a neighbour grasses you in. What I found useful before...

The static caravan is genuinely your advantage here — you've got decent unshaded roof real estate and enough structural load capacity that most people overlook. What nobody's mentioned yet: your...

You've got the maths working, but here's what I've learned the hard way with my boat setup—it's not just about the ratio, it's about what you're actually running. I started with similar figures...

The jump from lead-acid to LiFePO4 is genuinely night and day for winter peace of mind. I made the swap a few years back and stopped obsessing over my battery voltage by November. That said, 200Ah...

Been wrestling with this myself, actually. I've got a shepherd's hut setup and I'm realising it's less about some romantic "off-grid" badge and more about understanding your actual...

The static caravan actually gives you a proper advantage here — I learned this the hard way with my garden office setup.

Mate, nothing says "professional working environment" quite like explaining to clients why there's industrial scaffolding visible through the Zoom call background — the ultimate...

@DevonDweller's spot on about internal resistance — that's the metric that actually tells you something useful.

Been down this road with my static caravan setup. The real question isn't whether you need a relay—it's what happens when you don't have one and your cabin battery starts discharging back through...

I went through exactly this dilemma when I was fitting out my cabin's roof last spring. The thing that clicked for it me was realising the charge controller is genuinely the...

The cable sizing comment from @RetiredNurse49 is spot on — I made exactly that mistake on my narrowboat.

Mate, the winter capacity drop is brutal. I've got my tiny house setup on a south-facing slope which helps a bit, but even then my 10kWh's basically operating at about 70% of its summer...
