Great thread — @VanSue's interference point is massively underrated and I'd add one more culprit nobody's mentioned yet: engine-off detection. The Orion-Tr Smart has a configurable input voltage...

@KevScott the 4A relay contact catching people out is basically a rite of passage — I fried a cheap relay module learning that lesson on my van build, now I run a proper Victron Battery Protect as...
Had one on the narrowboat for a couple of seasons now. Magnet mount is brilliant when you're swapping cylinders at a marina — no faff, just slap it on the new one. Only gripe: signal can get a bit...

@QuietHiker that's a really useful tip about the dedicated Android phone — I'd not thought about forcing Bluetooth classic mode. Do you know which Android version you're running on that old phone?

Right, @RetiredSquaddie's teased us all with a mystery angle — don't leave us hanging, mate! What I will add, having run a small chest freezer through a shepherd's hut build for the better part of...

@LisaKelly66 has the right idea with the SmartShunt — know your actual consumption, not a guess. Quick maths: 200Ah × 12V = 2.4kWh usable (assuming you're not flogging it below 20% SOC), and a...

@RetiredNurse49 @PanelJulie both right, but if you're still chasing 201 and 215 after sorting the thermals, check your string voltages haven't gone rogue on a cold morning — my RS 450/100 threw a...

@IslandOffGrid same question as @SolarJunkie — what shifted you off the US5000s? For what it's worth, I've had two US5000s running with a Multiplus-2 GX for over a year now.

@WillWebb just to add to what @BMS_Geek and @OldSailor have already said — keep a detailed paper trail of absolutely everything.

Hard to diagnose a wizard loop when half the posts describing it have apparently also got stuck in a loop and never finished loading.

CarlBaker | Posts: 847 @LiFePO4Fan makes a valid point on tilt angle. To add some concrete numbers: at 54°N latitude, optimal winter panel angle is roughly 65-70° from horizontal.

Good point from @NaeClue on the analogy, though worth drilling into why this matters technically rather than just flagging it as odd. Victron's Phoenix Smart inverters are region-locked at...
@WonkyMender had this exact same thing on my narrowboat last spring — drove me mad for weeks! One thing nobody's mentioned yet: even when you nail those settings, the Cerbo can still drift over...

@PanelKate narrowboat experience is probably the closest analogy here — you're dealing with the same steel frame / warm interior / cold underside problem. The bit people miss is that...

@RetiredElectrician74 this is exactly what pushed me over the edge to think seriously about the boat setup.

BayTim | Posts: 89 Same issue on my boat last year, drove me absolutely mad before I figured it out. What nobody's mentioned yet — check your battery capacity setting in VEConfigure.

@Smithy my Victron BMV told me things about my own electricity habits that I genuinely wasn't prepared to hear emotionally.

@Macca64 yeah, forum's been doing this a lot lately — whole posts vanishing mid-sentence. Frustrating when it's actually a useful technical thread. I'll add what I know from my narrowboat setup...
Had this exact problem commissioning my Cerbo on a motorhome build. Turned out my MultiPlus wasn't fully detected on VE.Bus until I'd done a hard reset of the Cerbo after everything else was...

@RetiredElectrician74 know exactly how you feel — when I was in the transition phase before going fully van-based it was the standing charge that finally pushed me over the edge to cut the cord...
