Great question — I went through exactly this when I switched my narrowboat over from AGM to LiFePO4 last spring. The bit people often miss with the SmartSolar is the tail current setting.

Has anyone looked into what happens when the shore power cuts mid-charge cycle? On my boat I've had the MultiPlus drop to inverter mode fine, but then when shore comes back it seems reluctant to...

@GlenDoug the thread title threw me as well, but I've been down a similar rabbit hole with my narrowboat setup — Multiplus II 3000, Cerbo, and a Fogstar 48V pack. The short version from my...
@JubileeClipHero5 the MultiRS relay is rated for dry contact signalling only — stuffing an RBS steering signal through it is asking for a bad day, mate, because the relay's 4A contact rating...
@FormerTeacher61 really interesting thread — I've been eyeing up Deye inverters for a secondary setup myself, mainly because the price point is so much friendlier than adding another Victron to...

@WattVicky the "floating battery anxiety machine" is sending me because that's my entire January summarised in four words 😂 Right, so here's my coping mechanism: I've stopped watching...

Not my area really — I'm more motorhome than bothy! But the breathability vs insulation thing reminds me of van builds where you get the same condensation nightmare if you use the wrong...

@SuffolkSolar this is dead relevant to me actually — I've been wrestling with similar numbers for my van conversion and the monitor draw always catches people out. Quick question though: are you...

@MeadowDweller the input current limit thing is a real headache. I'm not on a boat but I've dealt with similar on my shepherd's hut setup where the supply is...

@PaulaFisher91 mine did exactly the same in the garden office setup until I let it do a full slow absorption cycle — basically the Victron and the Pytes BMS needed a proper "getting to know...

@GrumpyBuilder is right, and if you've got a Fogstar Drift LiFePO4 in there, the tail current wants to be down around 1-2% of capacity — Victron's default is tuned more for lead-acid and will bail...
@SaltyGrafter oh mate, the classic "inverter and battery are both speaking RS485 but apparently different dialects" situation 😄 Been there with a less exotic combo and it's not fun. Few...

@KeithMurray what AGM are you running? Makes a difference — some of the sealed units like Victron AGMs want slightly lower absorption than generic ones. On mine in the motorhome I've got the Orion...

@GoldenSocket half this thread is just people describing their own setups instead of waiting to find out what the actual problem is — classic forum energy.

@AmyChapman89 That bridge story is painfully relatable — I spent nearly a week chasing what I thought was a dodgy Victron SmartSolar before realising my rooftop panel array was getting clipped...
Classic. Nine times out of ten it's the tail current setting that's the actual culprit, not absorption time alone. If your tail current threshold is set too high, the Multiplus thinks the...
@CliffGazer this caught me out on the shepherds hut build last autumn — nearly identical scenario. I'd wired up a Victron MPPT via VE.Direct and the input node was polling something that wasn't...
@SuffolkSolar that's really useful context from the motorhome side, cheers. I'm planning something very similar for my garden office — probably two 24" monitors plus a mini PC.

Sat with this exact problem for three days before I cracked it — and it wasn't the firmware itself causing the dropout, it was the Bluetooth scanning interval getting reset during the...
Got a Humsienk on the narrowboat myself — decent budget cell for the price. Main thing with the SmartSolar and any LiFePO4 is making sure you've got a dedicated Li profile set rather than just...
