Does anyone know if there's a difference in cold-start behaviour between the pull-cord carb-fed generators and the inverter-style ones?
Been thinking about this after playing around with my Victron setup lately. The EVCS wallbox does a decent job of throttling charge current based on available solar — that bit works well enough.
Running almost identical on my garden office setup — Cerbo → Pi 4 → InfluxDB/Grafana stack. One thing worth adding: write a cron job to back up your InfluxDB data to a USB stick weekly.
@Lefty already nabbed the DVCC angle, so I'll add — check your BMS assistant version in the Multiplus-II too, older firmware had a nasty habit of misreading the Freedom Won's CAN comms and...

Been scratching my head over something similar with my garden office setup and wondered if anyone else has run into this. My Cerbo GX is showing negative wattage and current on the battery tile...
Been having a similar head-scratcher with my Cerbo GX setup in the tiny house build. I've got a Victron MPPT connected via VE.Direct and everything reads perfectly on the VRM portal — solar yield,...
@ExBrickie @LiFePO4Nerd both nail it on the overcurrent side, so I won't labour that. My actual question though — has anyone tested what triggers the BP to trip before reaching for a bypass...
@TID_Electric had one of these knock-offs... well, adjacent budget rack units in my motorhome for a bit before I upgraded to proper Fogstar.

@Fiona1974 made the right call — Fogstar Drift is genuinely excellent bang-for-buck and actually has a BMS you can trust. The core issue with mystery eBay cells isn't just dodgy specs — it's cell...

LindaCross66 | 847 posts | Gloucestershire @DownsCruiser makes a solid point about calibration. One thing worth adding — the SmartShunt's SOC will drift over time if it never gets a proper...

Been mulling this one over for a while and finally decided to post because I suspect others here have hit the same wall. My static caravan setup runs a Victron MultiPlus-II GX 48/5000 alongside a...
JohnDixon | 1,204 posts Had exactly this on my van conversion last January — panels were absolutely loving the cold clear mornings we had, genuinely pumping out numbers I hadn't seen all summer.
Had this exact issue on my narrowboat setup last winter. The Multiplus was declaring float after maybe 2–3 hours on absorption, even though the Fogstar Drift LiFePO4 cells were nowhere near fully...
Ever since the Victron MPPT RS 450/100 got nudged onto a newer firmware, my Pylontech stack has basically decided it's on a go-slow the moment it hits 98% — excess solar just vanishes into the...

@RetiredNurse49 got me thinking — I just zip-tied a Victron Battery Protect right next to the fridge rather than back at the battery bank, which halved my cable run and suddenly my Dometic stopped...
@Smithy just to be precise about this — the SmartSolar MPPT 100/30 doesn't have a physical relay at all. It has a virtual load output, which is a different thing entirely.
@BatteryTim yeah the vague docs thing is a real pattern with ECO-WORTHY — had similar with their panels, specs sheet was basically aspirational fiction 😄 For EV charging specifically (my use case)...

Been thinking about this after a mate asked me something similar last week — running a 12v compressor coolbox directly off the load output on a Victron SmartSolar MPPT. Short answer from what I've...
@ExChippie72 and @Jonno71 — the Modbus register map is where I'd start too. Registers 5 and 6 (charge current setpoint and enable/disable) are the obvious levers, but what's often overlooked is...
Been through almost exactly this decision two years ago with my garden office setup, so thought I'd chip in. The stone outbuilding looks appealing on paper — solid, permanent, already standing.
