Taffy42 | 156 posts @WelshVanLifer snap — narrowboat here too, and Pylontech US3000Cs talk to the Multiplus II via CAN bus so beautifully you'd almost forgive Victron for the price tag.

Hey @BenJackson — worth checking your battery capacity setting in VEConfigure. If it's set lower than your actual 200Ah, the MultiPlus calculates a skewed SOC and can trigger the dynamic cutoff...

Picked up a Victron SmartSolar 100/30 earlier this year and paired it with two 200W panels wired in series on the roof of my Sprinter.

Tommo10 | Posts: 847 Had the exact same headache with mine, @HarryJackson. Turned out the Bluetooth antenna on the JK board sits really close to the balancer circuitry, and when the active...

Picked up a secondhand MultiPlus 12/3000/120 a few months back and it's been brilliant — right up until the temperatures dropped last week.

@BrianLewis79 the app integration point is interesting — does it play nicely with anything beyond just the SmartSolar itself?

DonnaGibson67 | 847 posts | ⭐ Trusted Member @PikeRuss yes, had exactly this with mine! Turned out my phone's Bluetooth was the culprit rather than the SmartSolar itself — Android has a habit of...

@KevLee ten minutes? rookie numbers — I spent a full afternoon ringing Victron support before realising the Pytes BMS was just doing its job and the MP2 was completely innocent 😅 Worth checking...

Had the exact same head-scratcher with my Victron setup — turns out the VE.Bus BMS deliberately hides the battery monitor in VictronConnect because it becomes the battery brain itself, so you're...

My Victron SmartSolar once told me my tiny house battery was "float" at 9am in January — mate, that's not float, that's hypothermia.

GeorgeSmith97 | 203 posts | 🔋 Still Learning @CopperGaffer Had almost identical grief last January with my 304Ah bank in an uninsulated outbuilding.

Last spring I was deep into fitting out my tiny house on wheels (a converted Iveco Daily, if anyone's curious) and I'd budgeted for two 110Ah AGMs because that's what every YouTube video from 2019...

Following on from what @MountainGary said — worth mentioning that the Smart Battery Sense also gives you voltage sensing at the battery terminals, not just temperature.

@FinnTaylor78 get in quick before the gremlin strikes! 😄 On the load output question — worth knowing that on most MPPT controllers the load terminals are current-limited, so if you're feeding...

Great thread. Building on what @Harry1965 mentioned about Peukert — worth noting that for LiFePO4 the exponent should be set very close to 1.05 (some even argue 1.00), since LiFePO4 doesn't suffer...

Great points from @BarryWood and @CrafterConvert already. One thing I'd add for your Scottish Borders situation specifically - don't just plan for average winter days, plan for the worst-case run...

After losing power for three days during a particularly savage Scottish storm last winter, I stopped relying on "I'll sort something out if it happens again" thinking.

Following on from @JaneReid68's point about CT clamps — worth also having a look at whether your grid meter is properly assigned in VRM.

Something nobody's flagged yet — synchronisation history. My SmartShunt went through a dodgy patch last autumn where it hadn't seen a proper full charge in weeks (cabin sitting idle, cloudy...

Great thread — @Titch's point about VRM is spot on. One thing I'd add that's easy to miss on a sailing setup specifically: make sure your Cerbo GX (assuming that's your hub) is mounted somewhere...
