@FZ_Builds similar setup on my narrowboat — Multiplus-II, Fogstar 48V (two 206Ah in parallel), around 800W of panels.
@Tango same issue on my narrowboat last season — SmartSolar 75/15 dropping every 25 minutes almost to the second.
@EwanChapman the metal skin issue is the crux of it — insulation value becomes almost irrelevant once you've got that thermal mass radiating inward.
@CE_Builds has covered the error definitions well so I won't rehash those.
One thing worth checking that catches people out on the RS 450/100 specifically — ventilation clearances.
Good shout from @Turbo12 on the visualisation side of things.
Worth knowing that the charge algorithm display in VictronConnect only reflects what that device believes it's doing — when you've got...
Running this on my narrowboat with one addition worth mentioning — a UPS HAT (I use the Waveshare one) so the Pi survives voltage dips when the inverter kicks in.
Had the same headache on the narrowboat. Vapour barrier tape round any cable entries is essential — @CamperCarl's right about condensation being sneaky.
Got a Waeco CompressorCool in my van conversion and it's genuinely transformed things. The key difference nobody mentions enough is that absorption fridges need to be perfectly level and hate...
The capacity anxiety is real, especially on a narrowboat where space is tight anyway. I'd pushed lead-acid to its limit before going LiFePO4 on mine — constant monitoring, never actually using...
@AnneWatson's spot on about ventilation—that's what catches most people out. I've got flexible panels on my narrowboat and the difference between gluing them flat to the roof versus creating an...
Right, thought I'd share what I've managed on a proper shoestring budget. Got a T5 sitting on my drive and wanted decent power without bankrupting myself.
The Setup:
400W of rigid panels (two...
Spot on finding this place. I lurked for ages before posting on my narrowboat setup and genuinely wish I'd joined sooner — saves so much trial and error.
The thing about this community is...
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...
Good timing on this — roof loading is the bit most people skip and then regret. Worth checking your motorhome's manual for the actual weight limit; manufacturers are often conservative but it's...
