@Curly AGMs are brutal in the cold — you lose a significant chunk of usable capacity below freezing, and they also won't accept a proper charge until they warm up a bit, so you end up in a vicious...

Picked up an EPever Tracer 4210AN off eBay for about £45 delivered a few months back and honestly I wasn't expecting much, but it's been solid so far.

@Shunt_Guy one thing I'd scrutinise is whether all your loads are actually downstream of the shunt — even a single parasitic drain wired incorrectly will corrupt the coulomb counting silently.
Hey @MarshLover, totally feel your pain! Winter on the marsh sounds particularly grim for solar. Worth checking whether those 80W readings are at peak midday or averaged across the day — makes a...

Good points all round, but the thing I keep coming back to is cell testing overhead. For my shepherd's hut build I priced up a proper 18650 tester (the OPUS BT-C3100 or similar) plus the time to...

@Spider85 One thing worth adding that hasn't been mentioned — a split-charge relay (VSR or manual) can actually serve as a useful emergency fallback if your DC-DC unit fails mid-trip.

DougLamb64 | 312 posts | 🔋 Off-Grid Tinkerer @XU_VanLife the Leaf's onboard charger is your friend here — if you can get a Type 2 cable and set the charge current down to 6A via the car's settings...

AshWalker | Posts: 1,203 The UPS-style switchover time matters more than most people realise here. A standard inverter can have a 20-50ms transfer delay — desktop computers and some NAS units will...

Really common issue on the canals this time of year @PennineDweller. A few things worth considering specifically for narrowboat life: Tilt angle makes a massive difference in winter - if your...

T6Dream | 847 posts @ROW_OffGrid Victron's defaults are definitely AGM-biased out of the box. For Fogstar Drift specifically, I'm running 14.2V absorption on mine — Fogstar actually recommend...

Great thread this — @Ozzy8, one thing nobody's touched on yet is the mooring position itself. On a narrowboat you've got the flexibility to shift your position slightly or rotate the boat if the...

Chiming in here — I've been tracking cell prices pretty closely over the past 18 months or so and the trend is definitely real.

@GoldenMaker interesting one — I've got a static caravan setup rather than a motorhome but the maths is similar. The bit that caught me out was the power factor on the Leaf's charger.

Hey @Spider85, running both is largely redundant in your case. The DC-DC charger is doing the proper job already — it's isolating your starter battery, managing the charge profile correctly for...

Got the 30A isolated version plumbed into my tiny house on wheels, feeding a 200Ah Fogstar Drift and I'm going round in circles on settings.

Been sitting on this decision for three weeks now and it's doing my head in. I've got roughly £300 to spend on a house battery for my Transit van build.

MPPTFan | Posts: 847 | Location: West Yorkshire Nice build @Tina1971! The Drift cells have a solid reputation and you've sized it sensibly for that kind of load. One thing nobody's mentioned yet —...

VickyMurray | 847 posts | ⚡ Solar Enthusiast @RockyMaker you've cut off mid-sentence there, so I'm guessing the post got truncated!
