Been mulling this over for my narrowboat refit and wondered if anyone here has gone down this route with a similar setup. I'm looking at running a pair of Victron MultiPlus-II units and want to...
@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 —...

Been running a Pi 4 connected to my Victron MPPT and Multiplus via VE.Direct cables for about eight months now across both the van and the boat — two separate setups but same approach on both. The...
Hey @ExJoiner19, looks like your post got cut off mid-sentence there — "15 kWh Fogs..." — think you might have hit submit too early!
Really interested in this thread — I've been on the fence about adding local logging to my van build for ages now. Quick question for the group: is there much advantage to running InfluxDB locally...
Been through exactly this with my own setup. Short answer: trust neither blindly, but understand what each is actually measuring. The BMV-712 uses coulomb counting — it tracks charge in and charge...
Classic Pylontech winter sulk — mine did exactly this after 6 weeks sat in the motorhome on the drive. The bit nobody mentions: before you even think about recalibrating, check your inter-module...

Been mulling this one over since we started planning a proper power setup for the cabin build, so curious what others have done here. We're looking at running a Victron Multiplus-II 48V 5000 in a...
@FormerMechanic43 classic one this — worth checking your absorption voltage and tail current settings in VEConfig. A few things to look at: Tail current — if it's set too high (e.g.
@AshChild one thing nobody's nailed down yet — what's your actual usable capacity? A 200Ah LiFePO4 at 100% DoD is fine in theory, but Victron's own guidance (and most BMS specs) suggest staying...

Had exactly this with my 100/30 last summer when I was setting up the shepherd's hut build. Drove me absolutely mad for about two weeks before I figured out what was going on. Turned out my...
@NaeClue Running three 200W panels on repurposed BT tray on the roof of my narrowboat for going on two years now.

@BrianBrown ha, interpretive performance — that's exactly it. Mine did the hokey cokey for about three weeks before I figured out the input lockout voltage was the culprit. Running an Orion XS 50A...

My emergency backup setup came in just under £280 all-in, so yes — it's very much doable if you're strategic about it. The core of mine is a Fogstar Drift 100Ah LiFePO4 (caught it on sale at...

@MountainBarry while we wait for the rest of that sentence, I'll note the thing that catches most people out with the JK InverterBMS panel wiring is the pre-charge circuit requirements when...
@Chalky this one's a classic. I spent a miserable fortnight in the Scottish Highlands last year watching my Fogstar 280Ah bank refuse to charge properly because my 100/50 was using the default...
@KellyRobinson airflow is absolutely the key thing — I'd also add that the Orion really benefits from being mounted on a metal surface rather than wood or plastic.
Been going back and forth on this one for my garden office build and could do with some input from anyone who's actually running this combination. I'm planning to use a couple of Pylontech US2000s...
@ExJoiner9 classic symptom of buying cells that were "pre-balanced" by someone who clearly doesn't own a multimeter — what voltage did your lowest cell actually read when the BMS...
Been mulling something similar over for my garden office build and wondering if anyone's tackled this properly. I'm running a Victron MultiPlus-II 48/3000 in the office, paired with a 15 kWh...
