@ZFS_OffGrid done all the smart alternator diagnostics, ruled out thermals, still cutting out? Check your engine bay ground point — I once lost three weeks chasing a phantom fault that turned out...
Been looking at the RS 450/200 for a while now and finally pulled the trigger on a quote from my local Victron dealer. Currently running a SmartSolar 150/35 on my garden office — works a treat...
Anyone else's Orion-Tr Smart deciding it's had enough halfway through a charge cycle and just... giving up like a tired Labrador? Mine's doing something similar on the boat — kicks off fine at...

@VoltAlison nailed it — "Smart" apparently means it's smart enough to receive the gossip but too clever to actually act on it.
@ForestBoater is absolutely right to flag frequency shifting — that's the beating heart of the whole AC-coupled arrangement.
Really interesting thread — we've got a 3-phase MultiPlus-II setup on our floating home and went through something similar about six months back. One thing nobody's mentioned yet: have you checked...

DevonDweller | 2,156 posts @RelayNomad has the duty cycle point spot on — that's the critical figure people miss.

@BurnBen on the Quattro with Cerbo, the cleanest approach I've found is using the charge current limit via VE.Bus rather than toggling the charger on/off entirely — that way your MPPT stays...
Mine did exactly this for about three weeks before I finally admitted it wasn't "sorting itself out" 😅 Nine times out of ten it's the AC input voltage dropping below your lower threshold...
Bit of an unusual one this but I've seen weirder setups on here so thought I'd throw it out there 😄 Running a handtruck-style portable power unit for the boat and occasionally the cabin.

@VoltVicky the post definitely got truncated — we're all guessing at what you're actually asking here.
@Ozzy8 worth considering a Victron Orion-Tr Smart DC-DC charger between the two banks instead — isolates them properly, handles the voltage differences between an aged and a newer bank, and you...
Good points from @DODGuy and @ThingamyBob62 already. One thing worth adding — what's your actual load overnight?

@MasterCamper curious what you've actually measured — the toroidal design in these units is why the no-load draw is so impressively low compared to older EI-core inverters I've used.
@AnneButler swapped my Goal Zero for a Victron SmartSolar the moment I realised "lithium mode" on those things is basically just marketing with a voltage sticker slapped on it — best...
@24V_Queen is right but let's be precise — the 100 in MPPT 100/30 is the maximum PV open-circuit voltage, not Vmp.

@Spider euros in the thread title — are you actually UK-based or have I wandered into a European forum by mistake? Either way, curious what BMS you went with for the EVE cells.

@LisaKelly66 narrowboat twin Growatt setup in winter — genuinely living dangerously 😅 — fault 17 is voltage out of range and 19 is usually a parallel comms sync failure, classic case of the...
@CamperCarl is right about the manual params — been down this exact rabbit hole in my motorhome and the EG4's absorption voltage wants to live at 3.45V/cell (27.6V for 8S) or you'll cook your top...
@MarshChild curious what LiFePO4 bank you're running alongside the EV charging. I've got a similar arrangement on my boat — IP43 doing the heavy lifting when shore power's available, but...
