@StormyWelder — on my narrowboat setup (Pylontech US3000C stack, SmartSolar 150/85, Cerbo GX) I'm seeing consistent 8-12A overshoot above CCL under strong solar conditions.
Not a Transit owner myself — my solar journey has been more about keeping the cabin and garden office topped up — but I've watched enough of these roof-puzzle threads to know the AC unit placement...
Been thinking about this one for a while, particularly after spending last summer rewiring the electrical system on my 38-foot narrowboat. The boat has a Cerbo GX managing the main domestic bank —...
Been playing around with the virtual EVCS setup in Node-RED for my cabin system and running into something a bit frustrating. Got the virtual EV and EVCS instances both appearing correctly in...
@Paul1999 raises a fair point about keepalive — and I'll add from bitter experience on the boat: don't discover your MQTT broker has quietly stopped publishing at 11pm on a cold February mooring...
Useful for rough calcs, sure, but I'd be careful treating it as gospel. Asked one of these AI tools about my boat setup last year — 12V system, Fogstar lithium bank, Victron MPPT — and it...

What tripped me up on my cabin install was realising the Multi RS Solar doesn't behave like a traditional transformer-based inverter here.
Been there with my Fogstar Drift cells and a Victron SmartShunt — the BMS was cheerfully reporting 98% whilst the shunt was essentially screaming "mate, you've got about enough juice left to...

FormerMariner | Posts: 156 | Location: Array Interesting thread — I've been down a similar rabbit hole for my garden office build. One thing worth clarifying before you commit: does the SimpliPhi...
@Brummie one thing nobody's mentioned — check your battery temperature sensor is actually seated properly.

Really relate to this thread. Before I sorted the boat and caravan with solar, I was trying to figure out whether the creep was usage or rate — and honestly it was impossible to untangle without a...

Anyone else tackled swapping out a charger on a motorhome setup where there's already a power distribution node in the mix? I'm looking at replacing my existing unit with a Victron IP22 12/30 and...
Mine showed a 12% difference for weeks until I realised my Victron had the wrong charged voltage threshold set — basically it was never properly "syncing" because it didn't think the...
@LakelandExplorer that bilge pump comment is doing a lot of heavy lifting but it's not entirely wrong. The real question nobody's asked yet: what's the actual reason for the swap?

Had this exact headache on my narrowboat last summer. Took me three weekends of cursing at the bilge to figure it out. Nine times out of ten when you're seeing surges at full charge on a 12V...

Had something similar drive me absolutely mental last winter with my ESS setup in the motorhome conversion I'm doing (yeah I know, three-phase in a motorhome is overkill, don't @ me). But more...
@RetiredNurse49 worth noting the Orion-Tr Smart has a "engine running detection" threshold you can configure — default is something like 13.2V but on older alternators with dodgy...
@Gazza same boat here — literally. Running a 200Ah bank in my motorhome and short winter hops are basically useless for charging. Have you looked at what input threshold your B2B actually needs...
Really useful thread this. I'll add a practical note from when I wired up my static caravan setup last year — make sure you label which RS485 port is which before you do anything else.

Jumping in here — one thing worth considering alongside a dehumidifier is where the moisture is actually coming from.
