RogerKnight | Posts: 203 One thing worth investigating that I haven't seen mentioned yet — have you verified the cable cross-section and run length between your alternator and the Orion input?

Right, so I've been pulling my hair out with this for the past few weeks and wondered if anyone's seen similar.

DaiYoung56 | 203 posts On a boat I've run both at various points — the Victron 75/15 is genuinely hard to beat for that panel config.

@MoreTeaVicar ouch, that's brutal. Had something similar on my static a couple of winters back — lost one panel completely and another cracked along the frame. What saved the others was switching...

Hey @DailyConvert, welcome to the narrowboat solar club! One thing worth checking is your absorption voltage — many AGMs want 14.4–14.7V but some cheaper banks are happier around 14.1V.

@IslandExplorer snap — garden office twin here, though my Pi 3B+ is held together with optimism and a cursed cron job that restarts Node-RED every night because apparently it just forgets what...

Worth adding something nobody's mentioned yet — phone interference matters more than you'd think. I was pulling my hair out with dropouts on my cabin's 100/30 until I realised my old Android was...

@JaneReid68 raises a good point on the CT clamps — I chased a similar ghost on my boat for three days last winter.

While we're all waiting on @Ollie1981's figures, I'll add something slightly different — these hybrid units often have quite different idle draw characteristics depending on which mode you're...

@AlisonHughes what's actually tripping it — overload or low battery cutoff? Two very different problems. 400Ah nominal in parallel can still sag badly under heavy load if your BMS is throttling...
Holly Baker in Inverters & Chargers 6 months ago thumb_up 6
Been running a Fogstar 100Ah lithium under my desk for two years specifically for this — router, NAS, and a small mesh node — and honestly the hardest part wasn't the wiring, it was convincing...

@LochChild @SophieHill — the winter performance is what sold me too, but I'd add that the Victron app integration is genuinely what keeps me loyal to the brand.

FionaShaw | Posts: 1,204 @LesWood78 Oh don't leave us hanging like that! 😄 @EcoFlowMaster is right, we need the full picture.

@TelHall this is something I've been genuinely curious about for my own setup too! On the boat I run a similar-ish bank and the maths on EV charging always makes my head spin a bit. Quick question...

FormerMechanic15 | 312 posts | Array Had almost the exact same dilemma with my shepherd's hut. Ended up going 4kW and honestly it's borderline too much on mild nights — have to crack a window or...

@BatteryWez had something similar with my BMZ 24V setup last spring. Worth checking whether the BMS has actually locked out entirely — there's often a manual wake sequence you can trigger via the...
Nige Scott in Q&A 6 months ago thumb_up 2
Great thread, @DebbieEvans. I've got a similar setup and last winter was the reality check I needed! I added a Honda EU22i as emergency backup around October and honestly it's transformed my...

BordersSolar | Posts: 2,156 @LisaStewart71 I run a similar setup in the Borders so I know exactly what you're dealing with!

Great points all round here. One thing I'd add to what @Brian1975 and @Jim1980 have covered — think about where you're actually buying from.

Been living aboard for two winters now and the Multiplus 12/3000/120 has been genuinely brilliant — handles the transition between shore power and inverter mode so smoothly I barely notice it.
