@DriftGal raises a good point about the boat-specific stuff. One thing I'd add — the Multiplus has a transfer switch built in, so if you're ever on a marina hookup, a bigger unit handles shore...

SteveGreen74 | 847 posts | ⭐ Regular Contributor @JubileeClipHero5 Yes, done exactly this for about eight months now.
IA_Builds | 312 posts Worth checking your DC wiring as well as the inverter settings, @PhilFox99. With 4 cells in parallel at 12V you're potentially pulling 250A+ at the battery terminals during...

@Spud79 Worth noting something nobody's mentioned yet — on a narrowboat, inverter sizing isn't purely about peak draw headroom.

Hey @ExTrucker32 — to add to what @Paddy and @DeclanKnight57 have said, there's also the alternator to consider.

MPPTGal | 634 posts Had almost identical behaviour in my own shepherd's hut build last winter. What cracked it for me was checking the absorption time setting — mine was far too short and the...

@VoltTom the low-light harvesting difference is exactly why I made the switch on my motorhome build.

@PV_Fan I've been doing something very similar down here in Cornwall for about 18 months now. The key thing nobody mentions is state of charge management — I use a Cerbo GX to set a minimum SOC...
Boycie74 | Posts: 312 | Location: Floating somewhere on the Shroppie @KangooAdventure nasty situation that, Middlewich's not ideal for sourcing bits quickly. My belt-and-braces backup is a 20Ah...
ExpertLife | 2,341 posts | 🔋 Off-Grid Veteran Good thread this. One thing worth mentioning that gets overlooked — if you're running the van as your primary backup during a prolonged outage, keep...

Really good shout from @MoorRuss on the voltage drop — and that's actually the crux of why a basic split charge relay is such a poor match for LiFePO4 specifically.

After finally getting round to expanding my static caravan setup, I've ended up with a bit of an awkward situation.

@Shunt_Guy bold of you to trust a marine alternator to actually charge something — mine's basically just a decorative spinning accessory bolted to the engine block.

Hey @OllieThompson73 — worth mentioning that alongside your absorption voltage, the absorption time and tail current settings matter just as much with LiFePO4.

GlenNicola | 847 posts | ⚡ Solar Enthusiast @Gazza89 The Epever Tracer is actually a decent bit of kit — not "cheap Chinese tat" in the same bracket as some of the no-name stuff...

So I've just finished wiring up my Transit conversion and I'm second-guessing myself a bit. I've got a 200Ah LiFePO4 (Fogstar Drift) connected to two 175W solar panels via a Victron SmartSolar...

CrafterWanderer | 412 posts @Rodney58 What nobody's mentioned yet is that the Daly's coulomb counting resets poorly after partial cycles — it drifts badly without regular full charge...

Just finished wiring up my off-grid shed setup — 400Ah of lithium, 600W of panels on a Victron SmartSolar 100/30, but I've gone with a Growatt SPF 3000TL inverter rather than a Multiplus because...
Reply by Derek1967: @Foggy95 Running a similar setup here — cheap MPPT off Amazon into a 80W panel I rescued from a shed clearance.

@WattRoger had the exact same bother with my 75/15 a couple of winters back. Turned out the Bluetooth module was the culprit rather than the MPPT itself — connection dropping doesn't necessarily...
