@MistyTinker classic Venus OS Large CPU storm — the EVCS driver keeps hammering Modbus-TCP retries when the charger drops connection, and the GX can't recover gracefully before the watchdog kicks...
@RelayNomad is asking the right question. What's the actual charge source here? Solar via MPPT, mains via a converter, alternator? Because 48V LiFePO4 on a golf cart isn't exotic — the charging...

@LiFePO4Nerd raises the SD card issue and it's a real one — killed two installs before I wised up. Running Venus OS on a Pi 3B+ in my shepherd's hut, and the fix that sorted it for me was booting...
Running a Pi 4 with VictronConnect data piped through Node-RED into InfluxDB, displayed on a Grafana dashboard so gorgeous it makes my Multiplus II feel like a celebrity.
Got a Fogstar 200Ah 12V lithium sat in the van doing a reasonable impression of an expensive paperweight, and I'm wondering if it'll cope with running a small chest freezer through the night...

Ran into exactly this on the narrowboat before I sorted the configuration properly. The problem was my inverter charger (Victron Multiplus) was set to draw from the grid at the wrong threshold, so...

Really sorry to hear this happened — that sounds absolutely terrifying. Hope nobody was hurt. I've been doing a fair bit of research into budget LiFePO4 options for my static caravan and boat...

@GoldenTinker this is exactly the problem with our current tariff structure — the standing charge is essentially fixed infrastructure cost recovery, and Ofgem have consistently allowed DNOs to...

@SamFrost73 @WingAndPrayer similar story on my static — turned out a junction box on the roof had let moisture in over winter.

@Jock30 I went through something very similar when I was setting up my garden office — had an older Victron unit and wasn't sure whether to throw money at updating it or just replace the whole...
Stuck a few old cast iron pans under my shepherd's hut bunk as "thermal mass" — my dignity left shortly after, but the overnight temperature held surprisingly well. More practically: a...

@OldSailor makes a fair point about measuring at the combiner, but I'd also pull the PV input fuse and check whether the MPP Solar's internal MPPT input capacitors have gone leaky — I've seen this...
Scattered thought incoming: the one that really bit me on my motorhome Victron-to-Goodwe comparison was the battery comms protocol malarkey — Goodwe's BMS communication is proprietary enough that...
Been down this exact rabbit hole. Venus OS on a Pi is solid, but here's what nobody mentions — SD card rot. Running 24/7 logging will kill a cheap card within a year.
@RobJones85 had exactly this with my garden office setup — SoC was sat at N/A for ages and I nearly lost my mind.

@RetiredPlumber has a point worth finishing — the 48/5000, 48/8000, or 48/10000 variants change the maths considerably before anyone can give sensible advice. That said, the "2 per...

@Pylontech_Queen feel this hard. Running a 200Ah Fogstar Drift in the van with a Victron SmartSolar 100/30 and honestly December/January are a write-off for solar alone. What's saved me is a B2B...
@GaryParker97 to add a practical angle — if you haven't already, dig into the Venus OS settings and enable "Log to RAM only" or point your logging at a proper industrial-grade card.

@Jock30 ran my narrowboat's 2012-era MultiPlus through this exact panic — turns out the VE.Bus firmware was old enough to vote Conservative, but a MK3-USB dongle and a VictronConnect session...
