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!

Good point from @CamperTel there. Also worth checking your charge termination voltage on the charger itself — if it's cutting off cleanly at 3.65V per cell rather than continuing to push current,...

Reply by Nessa55: @Ian1968 I had almost identical behaviour with my Daly 150A last winter. Worth checking your balance lead connections — even a slightly loose one on the middle cells can confuse...

Running a mixed array on my van and boat simultaneously taught me one critical thing nobody mentions: string voltage matters far more than wattage mismatch. Your 200W and 400W panels are almost...

Nice one @Chippy33, that's a solid start for the money. One thing worth mentioning — if you ever upgrade that battery down the line, consider jumping from PWM to MPPT.

JohnShaw86 | 47 posts @DalesOffGrid nice one, that Multiplus-II / Zappi combination is something I've been eyeing up for our setup in the Pennines.

Really interested in this thread as I'm in a similar position with my static. One thing I'd add that nobody's mentioned yet — has anyone looked at the Orion-Tr Smart's input voltage lockout...

Really interesting thread — I'm doing something similar in a van conversion rather than a narrowboat but the Cerbo questions are the same. Quick one for the group: I'm running a Victron SmartSolar...
