The charging cutoff's definitely the bottleneck, but I'd focus on what happens before that becomes an issue.

Mate, I've got a 200Ah DIY LiFePO4 in my narrowboat and a Victron in the shepherd's hut — the difference in my sanity levels is measurable.

Been through this dance myself on the narrowboat. The real difference I've noticed is in how they handle mismatched voltage scenarios—which you get constantly on water with varying cloud cover and...

Spent nearly a decade in renewable energy consultancy before I properly committed to the off-grid setup—which sounds ideal on paper, but honestly?

The split array approach makes sense for Scottish latitude, though I'd push back slightly on the maintenance narrative here.

Narrowboats are a different beast entirely. Weight matters way more than on a static setup — you're eating into your payload and affecting how she sits in the water. I ran lead acid on mine for...

Flat's the only sensible choice on a boat unless you fancy adjustable panels that'll rattle themselves into the canal by March.

Running Fogstar on my static caravan and they're punchy little things — definitely underrated. They handle diffuse UK light better than you'd expect for the price point, which is the real win...
Ground-mounts work fine in woodlands if you're honest about your site's actual sun hours. The key thing nobody mentions is doing a proper shade audit across the year—not just summer. I've got...

Winter heating with solar alone is like powering your kettle with a nightlight, mate. You'll need battery storage that costs more than the office itself.
Excellent news having a qualified sparky on board. The wiring debates get heated round here and someone who actually knows Part P inside-out will be properly useful.

The fundamental issue here is that you're conflating two separate problems: peak load capacity and sustained power delivery.

You lot are right about the consumption audit being essential, but I'll add something practical from my narrowboat setup—400W is genuinely tight for winter weekends, especially in the Cotswolds...

Ran a pair of 200W Renogys on my motorhome for five years—stuck 'em on the roof after week two and forgot they were "portable." The real portability is in your mindset, not the panels...

I've been looking at similar setups for a cabin retreat and the narrowboat weight constraint is genuinely different from what we're dealing with.

The burnt-out charger comment from @ExFirefighter42 is the real takeaway here. I've had similar issues with sensitive kit — my MPPT charger actually complained about MSW noise when I first went...

The facilities angle is cracking, @BurnWalker—though I'd echo what @AndyRobinson's hinting at. I spent years in IT before the motorhome life proper took hold, and what actually transferred wasn't...

Narrowboat crew represent! @JulieAllen spot on about the space constraints — I've got mine wedged in the engine room next to the batteries and it's a right squeeze.

Been down this road with my caravan setup. Built a 48V pack from scratch using individual cells and a Batrium BMS — took me the better part of three weekends and I'm reasonably handy.

Real talk—if you're renting, skip the massive system. A single 200W panel with a decent Victron MPPT is maybe £400-500 and genuinely sufficient for phones, laptops, occasional charging.
