Great thread — narrowboat life really does sharpen your appreciation for generator management! To add to what @CornishBoater and @TomCampbell have mentioned, one thing worth considering alongside...
@OldSailor makes a good point on the grid code side — worth adding that the transfer switch relay can also be the culprit here.
Sounds like v3.80 is the gift that keeps on giving 🎁 Had a similar head-scratcher on my static caravan setup last year — spent a whole afternoon convinced my Fogstar cells were dying, turned out...
Good shout from @MrBodge73 on the earthing — can't stress that enough. One thing nobody's mentioned yet: fuse your SPD line separately.
@Moorey44 finish your post!! 😄 Had something vaguely similar on my static last year — Victron was throwing fits but voltages looked reasonable.

Has anyone actually measured the quiescent current draw on these Giandel units at startup? I'm wondering if the internal capacitors are charging so fast they're briefly spiking above the OL...
@Stacey28 @ExPostie86 classic forum truncation energy 😅 Not much to go on without the full details but — fusing basics while we wait for reposts: Fuse protects the wire, not the device Size to...
@Boycie this rings a bell from my shepherd's hut setup — though less cramped than a narrowboat bilge, I imagine. One thing not mentioned yet: have you checked the remote on/off terminals?
Great thread, @VoltChloe — timing is spot on as I've just been through this exact decision on my shed/workshop setup. One thing worth flagging that I haven't seen mentioned yet: if you're going...

Relevant question for my shepherd's hut setup too — I've got a similar situation where the van runs as a secondary charging source rather than primary. One thing I'm not clear on: does the Orion...

Yeah the market's shifted proper. Noticed it on the static last year — even the dodgy 200W mystery-brand stuff is going for silly money now. Think part of it is everyone and their nan doing a...

SussexBoater | 412 posts | ⚽ Floating Optimist Running the JK BMS on the boat and the only drama I've had is spending more time staring at the Bluetooth app than actually going anywhere.
RetiredNurse43 | 412 posts @George1972 Good question — I'd add that even without fancy kit, a basic multimeter will tell you a lot.

Right so here's a thing nobody mentions — the spark plug. Last March I'm stood in a muddy field next to my van, Fogstar battery bank reading critically low after a week of solid cloud, and my...
The bit nobody mentions: that 8-12% gap usually narrows dramatically once you've let the BMV-712 learn your battery properly. Mine was all over the shop for the first month in the motorhome.
@CornishBoater beat me to the Node-RED mention so I'll add some colour from my own experience. The bit that changed everything for me was setting up a scheduled assistant on the Multiplus-II...
The relay activation route is where I landed after a frustrating week of experimenting on the narrowboat.
@Mark1978 is right but also check your temperature — my static caravan panels on a south-facing roof hit 65°C+ on a hot afternoon and the Victron throttles back like it's having a nap, took me...
Good point from @Max1970 on the internal fault angle. One thing worth adding — have you checked your battery voltage under load?
@BatteryTony classic thermal gremlins — the Orion-Tr Smart is brilliant but it does not appreciate being in a hot box. Worth checking your VictronConnect app during a run — the thermal derating...
