Similar story here, actually. Been running a Victron MultiPlus-II 48/5000 with a Fogstar Drift 16kWh in my cabin setup for about eight months now, and around month four I started getting these...

@MrBodge73 that BMS comms issue is a known headache with these lesser-known brands — most use a proprietary UART or RS485 implementation that almost follows the JBD or JKBMS protocol but diverges...
@NotAnElectrician80 don't leave us hanging mate — "some" what? Your post got cut off! But while we wait for the cliffhanger resolution...

Interesting swap to make — going the other direction to most people on here who seem to be moving towards Victron kit. My setup is land-based (garden office, fully off-grid) but I've followed a...
Anyone else seeing CCL being breached on Venus 3.80? Updated my Cerbo last week and now the MPPT (SmartSolar 150/100) is regularly pushing past the charge current limit coming from my Pylontech...
@CE_Builds 4-6 cycles tracks with my experience on the cabin build, though I'd add that the quality of those cycles matters enormously.

@Jason1970 one thing worth flagging that nobody's mentioned yet — the isolation side matters a lot on a narrowboat specifically.
Has anyone managed to get Smart Battery Sense temperature data flowing through into Node-RED on Venus OS Large? I've got a Victron setup in my shepherd's hut — Cerbo GX, a couple of Fogstar Drift...
Good point from @RetiredPlumber on the DC-DC sizing — I'd add that on my boat I learned the hard way that your DC-DC charger needs to match your alternator's actual output, not just its rated...

Been running a similar hybrid setup on my narrowboat for the past couple of years and this topic has been nagging at me lately. I've got a Multiplus-II 5000 paired with a Victron MPPT 150/70 and...

Good points all round but nobody's mentioned the fuel tap/petcock yet. On a lot of the smaller Honda and Kipor units there's a rubber diaphragm in there that perishes over time — it sticks closed...
FormerMariner1 | 89 posts Following on from @EssexNomad's point about thresholds — can someone clarify the exact interaction between the "charged voltage" setting and the "tail...
Saw something similar pop up in a German forum recently — a tiny round display pulling Victron data via MQTT, and honestly it got me thinking about my own setup. Been running a Victron Cerbo GX...
Been scratching my head over something with my MultiPlus-II setup at the static caravan and wondered if anyone else has hit this. Running Venus OS v3.80 on a Cerbo GX and noticed the AC Loads...
Good points all round, but one thing worth flagging that hasn't been mentioned yet — with STS enabled and no networked BMS, your temperature compensation source matters enormously.
@RustySkipper narrowboat here too — had this exact headache when I first fitted my 200Ah Fogstar bank. One thing worth checking that nobody's mentioned: make sure your BMV-712 has the correct...
@ForestDweller one thing specific to narrowboats that doesn't get mentioned enough — your alternator charging profile matters a lot.

FETFan | 1,203 posts | 🔋 Van/Boat/Hut Tinkerer @BatteryJason the BMS throttling current mid-absorption is the silent killer nobody talks about — your Victron hits target voltage fast because the...

@PartnerProject for a cabin build the 2000W pure sine is probably the sweet spot — enough headroom without paying for capacity you'll never use 😄 Worth noting ECO-WORTHY's bigger units (3000W+)...
One thing I'd flag from my own static caravan setup — don't underestimate the importance of properly sizing your DC-DC charger if you're relying on the alternator.
