LiFePO4 doesn't off-gas under normal conditions like lead-acid does, but I'd still leave a small vent path in any enclosed cabinet — mainly because your inverter/charger kicks out serious heat and...
What @Davo79 said about the panels is spot on, and it actually took me a while to wrap my head around that when I first set up my boat system. The bit that clicked it for me was realising the...
Worth adding on the charger question — if you're on a really tight budget, the NOCO Genius range punches well above its price point and handles LiFePO4 profiles properly.
@HighlandExplorer interested in this too — I've got a static caravan running on Pylontechs and keep eyeing up the Eco-Worthy packs. Main thing I'd want to know is whether your Victron DVCC...
Different beast but same battle — on the narrowboat I rely heavily on alternator charging via a B2B and winter is genuinely grim.
Hey @MultiPlus_Queen, looks like your post got cut off there! You've got a couple of panels that don't appear... to be matching specs?

@TorJake the OP got cut off but I'll take a guess at what happened — classic issue when moving to lithium with a BMS that uses the VE.Bus BMS assistant. When you connect a Cerbo GX into the mix,...

@SamFrost and @PN_Camper — ooh this is relevant to me too! I'm currently wrestling with exactly this on my narrowboat.

@NicolaTaylor72 a Wakespeed WS500 paired with a decent alternator (I run a Balmar on my shepherd's hut rig, don't judge me) is basically cheating — it'll talk directly to your Victron system via...

@CamperGeek welcome to the forum — great first thread, you've clearly done your homework already. One thing worth adding to the toroid discussion: even if the transformer itself is genuine, the...
@Jock had similar grief with my AGM bank before I switched to lithium. The problem isn't just the peak voltage — it's duration.

@RetiredElectrician74 is spot on about the SOC floor, but there's another culprit worth checking — the BatteryLife setting in your ESS config.
@HighlandExplorer did you notice much difference in how your Victron kit talks to the new cells? That's the bit I'd be nervous about — Pylontech has proper DVCC comms baked in, whereas with...

@SamFrost the single-source charging scenario is where chemistry choice really matters. On my narrowboat I run LiFePO4 (Fogstar Drift cells) precisely because the BMS handles the tighter voltage...

Yeah had this on my van conversion last year. Worth checking your absorption time settings in VictronConnect — if it's set too short it'll bail out early regardless of actual battery state. Also...
@BayJason makes a solid point about the BMS — worth adding that the Skylla-TG and Quattro can both be set to charge profiles independently, which is where people get caught out.

Really feel this one @DodgyCaptain — I've been paranoid about this exact scenario ever since I started relying more heavily on my setup for EV charging overnight on the narrowboat. One thing...
Fogstar Drift gets my reluctant seal of approval — and I hate approving budget gear — but pair it with a Victron IP22 or IP65 charger and you've actually got something sensible rather than just...

@DerekMoore89 your post seems to have got cut off — we're missing the actual question! Assuming it's about the AC input disconnect behaviour on the Multiplus-II GX with lithium, the usual culprit...
@Jock the Orion's absorption voltage for AGM is non-negotiable — stray above 14.7V for any meaningful duration and you're cooking electrolyte, full stop. Key things worth checking: Temperature...
