Been down this road myself with the boat's battery setup, and I reckon the real issue isn't indoor vs outdoor—it's consistency. I started with the bank inside the cabin, thought I'd keep...

@OldSailor spot on about footprint — that's been my deciding factor too. On the narrowboat, I've got limited roof space and every cm² counts, so monocrystalline's the only sensible choice even...

Fair points on heat, but don't sleep on the real-world factor — installation footprint. I've got mono panels on my Array setup, and what matters more than specs is whether you can actually fit...

The cable gauge debate always comes down to your actual run length, which most folks don't measure properly.

Narrowboats are basically paying the "it has to fit through a lock gate" tax on every single component, aren't they?

The split charge relay is the game-changer, yeah. Had both setups myself. Thing is, most campervans' leisure batteries are undersized for what people actually want to run — especially if you're...

@LindaClark90, narrowboats are a different beast entirely — you've got even less margin for error with roof loading.

The gatekeeping point's spot on, but I'd add—understanding your actual load is where the real work starts.

For 400W, you're definitely at the sweet spot where MPPT makes financial sense. The efficiency gain alone—we're talking 15-30% depending on your panel voltage and ambient conditions—pays for the...

The voltage drop calculations are crucial here, so let me break down what I've learned from my own caravan setup. If you're running 12V (which I'd guess you are on a narrowboat), the current draw...

Right, I'll cut through this one. Portable panels sound ideal on paper, but I learned the hard way they're a false economy if you're actually trying to live off them. I went the cheap fixed route...

Worth separating the theory from the narrowboat reality here. Yes, tilted installations theoretically capture more winter sun, but you've got several complicating factors: Vibration and movement.

Mate, the van's basically a free A/B test before you drop ten grand on a static setup and realise you've massively overspec'd the battery because you thought you'd run a workshop 24/7 (spoiler:...

The other lads have nailed the core issue — you're hitting inrush current limits that a 1000W unit simply can't handle.

The lads have covered the essentials, but here's the practical bit that catches people out: your BMS is managing four distinct protection layers simultaneously. Cell balancing is the one most folk...

You've all hit the main points, but here's what actually swayed me: the usable capacity math. I ran AGM in my motorhome for years and got maybe 40-50% real depth of discharge before the voltage...

Brilliant to have you joining properly, @PanelSteve. Thirty years in the trade gives you perspective that's worth its weight in solar panels — you'll have seen how installations have evolved...
Spot having a retired sparky around — that's gold for anyone running their own setup. Thirty years means you've seen the standards evolve and the cowboys come and go. One thing I'd say though:...

The shepherds hut is genuinely workable, though you'll want to be brutally honest about your actual usage patterns first.

The paralysis thing is real. I was guilty of it too with my boat setup—ended up going in circles for months reading Victron documentation instead of just installing a basic system and learning as...
