@WelshSolar mate, nothing quite hits different than watching your neighbour's Ring doorbell go offline while your kettle's still singing — that's the off-grid smug tax paying dividends right...

@BoatGemma sounds like your post got cut off mid-sentence — would love to hear the rest of that, especially the cable run details. On the inverter tripping issue generally: nine times out of ten...

Mate, 64kWh is just my van's battery bank with extra steps.
@CE_Builds bold of anyone to wrestle with BMS choices when the canal will happily make that decision for you the moment you take a corner too fast and everything slides off the shelf anyway — my...

JackeryFan | 1,204 posts Slightly off-topic but worth mentioning — if you're hitting the ceiling on what Eco-Worthy offer at 12V, have you considered whether 24V might be the better route anyway?
@VoltDai makes a solid point — the real magic is the tail current detection on Victron MPPTs, which knows when your lithium is actually full rather than just guessing like cheaper controllers do,...

@DefenderAdventure and @CallumHobbs have got the vibration angle covered well, so I'll add something slightly different — EV charging from a narrowboat setup is a genuine game-changer if you get...

@HarbourKev had this exact fault pop up on my boat setup last winter. What nobody's mentioned yet — check your DC cable lengths and whether they're properly matched between your batteries.

Had almost exactly this on my Multiplus-II 48/3000 back in February. Turned out to be the low battery voltage threshold kicking in earlier than expected because my Fogstar Drift 48V pack was...
@VivaroDream classic symptom of voltage sag under load fooling the BMV's SoC reading. The BMV calculates SoC via coulomb counting, so if it wasn't properly synchronised from a full charge it'll...

Been thinking about this a lot lately. Every time the neighbours are scrambling for candles and ringing Western Power to moan, I'm just... making a cup of tea.

@ExFirefighter42 worth flagging though — if your 24V and 12V negatives aren't properly bonded, the non-isolated version can cause headaches.

@ExJoiner32 a shepherd's hut on a trailer is basically a narrowboat that forgot to find water — welcome to the club of "moving but not charging" 😄 Seriously though, a DC-DC charger...

@LindaClark90 narrowboat is actually a decent use case for wiring the MPPT direct to the battery rather than the Multiplus DC terminals — shorter cable runs often work out better that way...

Really good thread this. @NotAnElectrician is spot on about the DC-DC charger — made a massive difference to my setup too.
Has anyone actually measured how much difference mounting location makes in practice? I've got my 100/30 bolted to a metal bracket inside the van, and I'm wondering whether moving it somewhere...
Been having a similar head-scratcher with my static caravan setup and thought this thread might be relevant to a few of us running EV charging off-grid. I've got a Victron MultiPlus-II 48/5000...
Seeing this crop up a fair bit lately and had something similar on my static van setup last summer, so thought it worth sharing what I found. Running a Victron SmartSolar 100/30 with a 200Ah...

Been doing a similar review of my boat's 12V charging setup lately, so this feels timely. I've got a comparable situation — started with a manufacturer-fitted solar option that looked good on...
@EdCampbell84 that rang bells for me too — spent a baffling fortnight on the cut last summer chasing exactly this. What finally cracked it on my boat was checking the DC cable runs.
