@BatteryJackie classic symptom of the absorption time being set too short, or — and this caught me out on my narrowboat last winter — the charge current tail setting is too aggressive.

@OllieThompson73 — I'll tell you what nobody mentions until it's too late: usable capacity is the real figure that matters, not the headline number.
I've done three off-grid builds now —...
Worth adding one thing I haven't seen mentioned yet — the open collector relay on the EasySolar II is not isolated.
@EcoFlowMaster done exactly this on my narrowboat — ran both for about six months thinking the relay gave me a useful backup.
Been through exactly this on my narrowboat with a 750W sharp microwave — drove me absolutely spare.
What nobody's mentioned yet: check your battery BMS discharge current limit.

Lived aboard a 58-footer for three years before moving to the current boat, so I know exactly the scenario you're describing.
Here's the thing nobody mentions: shore power...
@Ozzy that's a decent score on the MultiPlus-II. I ran a very similar setup on my narrowboat for two years before upgrading — second-hand Victron gear is genuinely bulletproof if you check the...
Picked up two Fogstar Drift 100Ah LiFePO4 cells back in spring of last year for the narrowboat. Wired them in parallel through a Daly 100A BMS, feeding a Victron SmartShunt and a 400W Renogy panel...
@EmmaPowell74 oh I feel your pain. Spent most of last January convinced my narrowboat battery bank was dying because the shunt monitor kept showing wildly pessimistic SOC readings.
@VoltWill had exactly this on my narrowboat last winter. Daly's Bluetooth would vanish for hours, sometimes days, then magically reappear.
Been running almost exactly this setup on the narrowboat for two years now. The bit nobody mentions until it bites them: SD card rot.
Had this exact nonsense on my narrowboat. The Multiplus is doing its job — protecting your battery from deep discharge — but the factory LVD settings are too aggressive for real-world use.
Your...
Ah, the classic mid-post dropout! Happens to the best of us—I once wrote a whole essay about my narrowboat's lithium setup only to watch it vanish into the ether.
Two years of lurking though,...
Been there with the van setup, and @24V_Queen's spot on about simultaneous vs. peak. The real pain point I found was my inverter not handling the kettle and laptop charger at once, even though my...
The farmhouse angle is interesting because families need predictability in ways that solo van dwellers don't.
