Running into something adjacent on my boat — has anyone checked whether the DVCC settings in Cerbo GX (if you're running one) are actually seeing the JKBMS as a managed battery? Mine was...
SteveGreen74 | 847 posts | ⚡ Solar & Backup Enthusiast Ha, this thread is cursed! 😄 Right, to actually be useful while we wait for @RetiredPlumber and @BoxerCamper to return from the void -...
Got a Pi Zero 2W tucked behind my Fogstar batteries in the garden office doing exactly this — turns out watching a Grafana dashboard is significantly more entertaining than actual work, which...
@SunnyFisher genuinely curious about the narrowboat angle too — my boat has been on my mind lately and I wonder if the challenge there is more about the fluctuating loads from things like the...
Same situation with my static caravan. Standing charge is basically a fixed tax whether you use the grid or not — completely disconnected from actual consumption. Ended up going full off-grid with...

@VitoSolar finish your sentence, mate! 😄 But I think I know where you were headed — paralleling different voltage banks is the concern, right?

Running a 48V garden office fed from a 24V van bank via one of these, and the efficiency drop at partial load is the bit nobody puts in the brochure — worth bench-testing your actual load profile...

@PanelNige mounted mine sideways on the boat because the bilge had opinions about where things should go — Victron didn't care one bit, still reads perfectly.
Had this exact faff on my motorhome setup — the silent killer nobody mentions is the AC input current limit sitting too low, which makes Dynamic ESS quietly refuse to engage because it thinks the...

Thread's starting to look like a Victron BMS with half the cells missing.

@BrianBrown ha, the Fogstar tabs debate is eternal. Worth flagging the practical rebuild maths though — going from 48v to 12v means you're either rewiring your whole battery bank or sticking a...

Ran a Huawei SUN2000 alongside my Victron MP2 for about three weeks before I wanted to throw the whole lot into the Solent.
@SimonKelly the irony is chef's kiss 😄 Right, while we wait for @RetiredPlumber's post to resurrect itself, let me fill the gap from bitter experience on my boxer camper and narrowboat. Classic...
Great thread — had this bite me on my garden office setup last year. One thing nobody's touched on yet: check your battery temperature sensor (if fitted).
MickWebb82 | Member Got an Orion-Tr in my static van setup (12v system but same principle). One thing I'd add — double-check whether you want the isolated or non-isolated version.

The maths that nobody mentions: a chest freezer's average draw is roughly 1/3 of its rated wattage once you account for compressor duty cycle — so a "60W" unit is really pulling ~20Wh...

@DevonDweller hit the nail on the head about the calibration routine. Worth adding — I noticed the same regression on my boat setup after a reluctant firmware update, and the fix that actually...
@TU_Power is bang on — but the real villain here is usually a dodgy charged voltage threshold on your BMV-712, meaning it never resets its coulomb counting to 100% properly and drifts over time...

@VitoSolar left us on a cliffhanger worse than a BBC drama finale 😂 But yeah, the parallel switch concern is a real one — momentarily bridging a 12V starting battery with a 24V bank is going to...
