BenKing80 | 47 posts @TimGraham the PWM issue is a real pain with AGMs — the controller's voltage-based SOC estimation gets thrown off because PWM charging keeps the battery in a pseudo-absorption...

Running almost identical kit @CrispyWelder — Cerbo GX is brilliant until you realise half your non-Victron gear just sits there giving it the silent treatment. 🔇

Finally took the plunge last month and replaced the tired AGM starter battery on my 28ft sailing boat with a 100Ah LiFePO4 (Fogstar Drift).

Really glad this thread exists — been running a Pi 4 at my cabin for about six months doing exactly this. One thing nobody's touched on yet: data visualisation.

Yep, been there. My Daly on the workshop bank used to trip at anything below 5°C until I dug into the PC software and nudged the low-temp charge cutoff down to 2°C — which is about as far as I'd...

Looking at putting together a 200Ah 12V LiFePO4 bank for my boat. Running a small fridge, nav lights, VHF, and I want to add a basic EV-style shore charging setup when I'm in a marina.

NeilAllen | 267 posts Good setup @DuctTapeDave62 — one thing I don't think's been mentioned yet is making sure your input cable runs to each unit are as equal in length as possible.

Lefty92 | 847 posts @VanDerek Nice setup with the Fogstars! The honest answer is: yes, but you need realistic expectations. I've been doing exactly this with a Zoe parked alongside the van.

Kelly1983 | 156 posts Similar setup here — went 100Ah Drift to test the waters before committing. One thing I haven't seen mentioned yet is the low-temperature cutoff behaviour.

Nice to see this thread — been meaning to post about my own setup for ages. Running a Pi Zero 2W on the motorhome, pulling Victron data via VE.Direct straight into Node-RED.

Good shout from @WingAndPrayer88 on the RF interference — worth bearing in mind if you've got an inverter nearby. One thing I'd add from my shepherd's hut setup: firmware version matters more than...

Paul1975 | 847 posts @TransitConvert the Orion-Tr Smart is a solid choice for that application, but worth clarifying — are you planning to run a cable from your van when it's parked nearby, or is...

ShortCircuit56 | 134 posts Good shout from @WingAndPrayer88 on the RF interference front — worth investigating that.

@Brummie86 on my narrowboat build I had cell drift creep in around the 6-month mark too — turned out my bus bars weren't torqued evenly and one connection had slightly higher resistance, causing...

Right, so I've been piecing together a budget system for my Transit van conversion over the last few months and I'm fairly chuffed with how it's come together.

Great points from everyone so far. One thing worth adding — have a close look at the Vmp (voltage at maximum power) of each panel, not just the wattage.

@CallumHamilton83 You're absolutely not imagining it. The core difference is that PWM essentially drags your panel voltage down to match battery voltage — so a 18V panel charging a 12V battery...

I've been running a 200W panel on my Transit Custom since September and it's been brilliant through the summer, but now we're heading into November I'm starting to wonder if I've been kidding...

VanBarry | 847 posts @WhatsAFuse65 you've cut off your typical daily load there, mate! Finish that sentence and you'll get much more useful answers from folk here. That said, 3kWh can be perfectly...

Running a mixed second-hand bank on the boat for two years and the real killer nobody mentions is internal resistance variance between mismatched batteries — your weakest cell drags the whole bank...
