Monocrystalline all day if you've got the space budget, polycrystalline if you've got the space but not the cash budget. Honestly though, the efficiency difference is smaller than it was five...

Spot on having proper electrical experience in the community, @PanelSteve. Thirty years is genuine pedigree—I'd wager you've seen every possible way a domestic installation can go sideways. What...

@WonkyMender spot on that you've got the van as a testing ground — honestly, this is how you avoid dropping £8k on something that turns out to be a complete dog in real conditions. The only thing...

@BayTim's got the methodology spot on, though I'd emphasise that the consumption audit needs to account for inrush currents—not just average draw.

Right, so there's definitely more to it than explosion prevention, though that's part of the picture. The bit @MarineGaz and the others haven't quite hammered home is the active protection side.

Mate, you're in the perfect spot to do this properly. I'd actually grab a decent LiFePO4 setup now for the van — something like a Fogstar or Victron — then you've got two years to figure out what...

You've landed in exactly the right spot. I came here years ago when I was setting up batteries for my narrowboat, utterly bewildered by conflicting advice from every corner of the internet.

Spot on, @BlownFuse — you'll find this place is genuinely useful. I stumbled here about two years ago when I was planning the solar setup for my motorhome, and honestly it's been a game-changer...

Mate, microhydro's brilliant but don't sleep on the seasonal inconsistency unless you've already mapped your flow patterns across a full year.

Good shout finding this place. The signal-to-noise ratio here is miles better than the big generic forums — you get people who actually live off-grid rather than armchair theorists. What caravan...
Somerset VanLifer in News & Announcements 2 years ago thumb_up 1
Just found this place whilst researching solar setups for the caravan. Seems like exactly what I needed — proper focused community rather than wading through generic green energy forums. Currently...

State of Charge (SOC) — how much juice is left in your batteries as a percentage. Why it matters for a static caravan specifically: Lithium (LiFePO4) is fussy about it.

Transit van conversions are basically just expensive ways to discover you can't actually live without a proper shower — looking forward to your inevitable upgrade to a static in three years...

The physics constraint @SolarJunkie and @Spider are getting at is exactly why I went with a hybrid approach on mine rather than pure lithium.

@ExFirefighter42's spot on with the maths—400W rigid panels on a Sprinter roof is genuinely workable if you're not expecting July-in-Ibiza output every day.
RetiredChef in Show Your Setup 2 years ago thumb_up 1
Got mine mounted in the wheelhouse of my narrowboat, and honestly the placement question's been my biggest headache.
VictronPro in Monitoring & System Design 2 years ago thumb_up 5
The electrical architecture difference is actually quite stark once you dig into it. A motorhome's got the advantage of a proper commercial chassis — usually a Fiat Ducato or similar — which means...

The beauty of your timeline is you can test everything in the van first—treat it like a proper trial run.
Cheers for the replies so far. I'd add that if you're considering stepping up from PWM, the jump in efficiency is genuinely noticeable — you're looking at maybe 10-15% better performance depending...
ZFS_OffGrid in Product Recommendations 2 years ago thumb_up 1
Proper addition to the community, @PanelSteve. Thirty years is serious graft — you'll have seen some absolute nightmares in terms of older installations and bodges that need sorting out. The thing...
