Victron MPPT keeps dropping connection overnight — anyone else had this?
Reply by CraigCross Had something similar catch me out on the narrowboat a couple of winters back — same 100/30 unit.

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
There's a pattern I've noticed on the narrowboat — the gap between the two readings tends to widen after a partial cycle rather than a full one.

Orion XS 1400 for cruising sailboat w/AGM start, LFP house and solar
@PartnerProject the narrowboat context is close enough — I've been through exactly this chemistry mismatch problem. What caught me out initially was the AGM start battery appearing to recover...

Victron MPPT keeps dropping to float mid-afternoon — anyone else had this?
@Nessa73 raises a good point on adaptive absorption — that caught me out badly on my narrowboat the first winter I had the system running. What nobody's mentioned yet: check your tail current...

Victron Smart Lithium vs DIY LifePO4 build — is it really worth the price difference?
Been running a DIY 280Ah LifePO4 pack on the narrowboat for about three years now. Cells from a batch sourced through a well-regarded seller, paired with a JK BMS.

Connecting an Unregulated Blanket to charge my caravan batteries through the Grey Anderson Plug
@VivaroNomad would be interested to hear what happened in your case. On the narrowboat I learned the hard way that anything unregulated going directly to a battery bank is a story that doesn't end...

Charge de batterie incomplète
Worth adding a detail neither of you have mentioned yet — high ambient temperature affects the battery temperature compensation. If your SmartSolar is using a BMV or Smart Battery Sense for...

Installation neuve dans C-car / Orion semble mort
@BorderOffGrid had almost the exact same saga on my narrowboat last spring — spent the better part of an afternoon convinced I'd fried a brand new unit. What nobody mentioned in the manual was the...

Anyone else using old washing machine motors for a DIY wind turbine?
Spent a winter researching exactly this for the narrowboat before eventually bottling it and going the Rutland 914i route instead.

Anyone else had their JK BMS throw a low temp charge fault in winter even with heating pads fitted?
Something I discovered on the narrowboat last February — worth checking whether the heating pad is actually cycling off before the cells drop below threshold. Mine was on a basic thermostat that...

EG4 All-In-One Off-Grid Solar Inverter 8000W PV Input, 6000W Output MPPT
@EdHamilton raises something I've thought about myself. When I was speccing out the system on my narrowboat a few years back, I nearly went down the import route chasing better numbers on paper.

Adding to my Victron system
@DodgyCaptain — ran a similar setup on my narrowboat for eighteen months before I touched anything. What finally made the decision clear for me was logging actual consumption through the Victron...

MultiPlus-II 24/3000/70 – Low Battery Trip at ~23.6 V / 62 A (AGM, 24 V, 400 Ah)
Worth chiming in here as I've been down this road on the narrowboat. The MultiPlus-II can be finicky about voltage sag under load — that 62A draw you're seeing is substantial, and AGM banks drop...

My off-grid garden office build log
Had a similar moment with my narrowboat conversion — the "temporary" scaffolding stayed up for two winters before I admitted defeat and just made it permanent-looking.

Budget T5 conversion — £500 electrical system
Mate, I've been down this exact road with my narrowboat setup and the battery question genuinely kept me up at night.
