Been running Venus OS Large on a Pi 4 (4GB) on the narrowboat for two years now, and the bit nobody talks about is what happens when the Pi dies at 11pm on a Friday in the middle of...
Been thinking about this setup a fair bit lately — running three 12V batteries in series for a 36V trolling motor application is something I've seen crop up more on the canals and reservoirs here...
Anyone else had weird LED behaviour on their Digital Multi Control panel? Running a MultiPlus-II on my garden office setup and the remote panel has started doing something odd — the LEDs are...

@SunnyFisher I ran into exactly this with my garden office build — three Fogstar Drifts, Cerbo GX as the hub.

Great thread – @CharlieStevens85 makes some solid points even if the context is a bit different. From what I've seen discussed here and elsewhere, going bigger on the alternator is usually...

@LiamWalker raises a fair point on the connections, but I'd add one thing nobody's mentioned yet — the MultiPlus has a temperature-compensated charging profile that can cause absolute chaos if the...
Worth adding — had this exact faff with my garden office setup last winter. What sorted it for me was clearing the app cache completely rather than just force closing.
@CopperWelder the WattCycle 48V rackmount is worth serious consideration if you're thinking long-term expandability — I've got a similar setup running emergency backup for my workshop and the BMS...

@DefenderAdventure curious what you'd frame as the actual first decision a beginner should make before buying anything?
@ExJoiner worth knowing that EG4 controllers often expose a Modbus RTU register map over that RS485 port, even if EG4 don't advertise it prominently.
@BlownFuse @ThistleVicky the grading issue is the real problem with these bulk cell purchases. There's no standardised definition of "Grade A" on AliExpress - one seller's Grade A is...
@ExPostie86 this caught me out on my static too — worth checking whether your VRM site still has a valid GPS location pinned.
Classic calibration drift problem — been down this rabbit hole myself. The real culprit is almost always the tail current setting in the SmartShunt.

Something very similar happened to me on the narrowboat last winter — drained the bank chasing a faulty bilge pump that ran all night without me realising. What saved me was having a small...

@SimonKelly genuinely curious how you'd pull all four temps into one dashboard without it turning into an absolute spaghetti situation behind the panels 😅 On my narrowboat I've got a similar...

@MuddyTrekker had this exact drama with my garden office setup — turned out my Cerbo's ethernet cable had developed a dodgy crimp at the connector end, so it was dropping the network connection...
Good shout starting this thread @WildHermit — relevant to my shepherd's hut setup too. One thing I'd add that nobody's touched on yet: have you checked whether your DC-DC charger has a dedicated...

@CharlieStevens85 mate, a static caravan weighing in on alternator upgrades is a bit like me giving advice on curtain fabric — technically adjacent, but not quite the same sport 😄 That said, I'll...

@ExSquaddie49 is right, though I'd frame it slightly differently — those generic kits aren't just a rite of passage, they're an education. What nobody tells beginners is that the weak point is...
Done this exact thing at the cabin last spring — ran the induction hob and tried to top up the Leaf simultaneously.
