@MoorDweller ran almost this exact setup on my narrowboat for a season before I sorted it properly. The issue nobody's mentioned yet is charge source priority — if your MPPT and the split-charge...

MarineSam · 447 posts @SamWhite worth checking your battery temperature compensation settings in the Victron app — the SmartSolar has a dedicated temperature coefficient setting (usually around...

Hey @Chunk75, gutting timing on that update! Just to add to what the others are saying — have you tried toggling the BMS Bluetooth off and back on via the physical button on the unit itself rather...

Running a Victron SmartSolar 100/30 with a 200Ah lithium (a Fogstar Drift 12V) in my van, and over the last few weeks as temperatures have dropped I've noticed the SOC reading on the...

@DaveMoore70 kettle's almost certainly your culprit mate. Even a "small" one is pulling 1000-1500W and the Drift's BMS can be touchy about sudden high-current spikes, especially if your...

Really relates to my situation — I've got a similar lithium setup on my narrowboat and the "watching the percentage drop" anxiety is real. Quick question for the thread: has anyone...

Really glad this thread is gaining traction — great to see so many different setups represented here. @FellLover welcome to the forum!

@Spud nice idea keeping it fully isolated. I run a similar setup but land-based — Drift 100Ah sat in a dry box in the garage, completely separate from my main Victron/Fogstar bank. One thing worth...

Woke up last weekend to a dead 12V system in the static. Temperatures had dropped to about 3°C overnight and my Fogstar Drift 100Ah had shut itself off completely.

@VickyFisher 11.8v resting on a LiFePO4 is genuinely outside the normal plateau — you'd expect somewhere between 13.2v and 13.3v fully charged, dropping to maybe 13.0v at 50% state of charge.

The £60 vs £200 maths hits different when you realise the Pi also runs your MQTT broker, Node-RED automations, and a Plex server simultaneously — Cerbo GX can't say that. 🫡

Worth adding — the bit that caught me out initially was the MK3-USB interface for talking to the Victron kit.

Great thread — been running something similar on my shepherd's hut build for about eight months now. One thing nobody's mentioned yet: I've got Node-RED triggering smart charging schedules for the...

Last year I put together a 200Ah 12V bank using four Fogstar Drift 200Ah LiFePO4 cells with a Daly BMS.

Not directly related to the garden office side of things, but I've been sizing up something similar for my van build and the one thing that's tripped me up is underestimating winter...

@GoldenBodger — one thing nobody's mentioned yet: check whether the unit is rigidly mounted to a wooden panel or bulkhead.

CarlBaker | 312 posts Worth adding a practical workflow for anyone actually buying these: bring a proper load tester, not just a multimeter. Resting voltage tells you almost nothing useful.

@WendyLewis mine did the same in my static van last January — turned out the sensor was reading the air around the BMS rather than the cells themselves, so it was cutting out at 3°C while the...

Bit of a different angle from me — my EV battery isn't a home backup, it is the home. Got a second-hand Hyundai Ioniq pack fitted to the boat about eighteen months ago.
