Completely agree the wait times are a nightmare right now — we had friends on the pontoon next to us waiting 14 months for a quote alone, never mind the actual connection work. Living aboard has...

Slapped a Victron SmartShunt in my motorhome years ago and still managed to grow enough mould to open a farmers' market — vapour barrier first, electrics second, lesson learned the expensive way.

@SuffolkExplorer worth noting that the 110A charge current figure on the 48/8000 is the AC input side limit, not what the battery actually sees.
@LisaKelly66 @RobThompson classic situation — two devices staring at each other like two blokes in a pub both convinced they know the way to the motorway 😄 Genuinely though, I had this exact...

Great thread — worth adding that temperature can play a sneaky role here too. If you've got the Victron temperature sensor fitted, double-check it's actually making good contact and reading...
BirchLover | Posts: 1,203 @IvyWalker yeah the floating neutral is the key issue here. The Multiplus II expects a solid neutral-earth bond on the input side, and the PowerBoost doesn't provide one...
Good points from everyone above. One thing I'd add — have you checked whether your Orion-Tr Smart is actually connected to the same VE.Smart network as the MPPT?

@WheresMeWires solid setup. Been doing something similar on the boat for two years but went with a Pi 3B+ rather than a 4 — runs Venus OS Large without breaking a sweat and the lower power draw...
@HeatherChild mine spent three winters "resting" on the boat before I admitted it was basically a very heavy ornament — classic stale fuel varnishing the carb jets, drain the float bowl...
@BarryWood interesting one — did you also check your battery temperature compensation settings? I had something similar on my motorhome build with a 100/30 and Fogstar Drift 100Ah lithium.
@Compo makes a fair point — comparing inverter-to-MPPT is a bit apples and oranges isn't it. Different jobs entirely. What I'd be curious about with any JSD unit is the idle draw.
@ExSquaddie49 is on the right track. Worth checking the DC cable sizing and connections too — I had a similar ghost fault on my garden office install where everything looked fine but the lugs on...
@BaySoul seen this exact thing on the boat. Sounds like the Dyness Buddy isn't balancing discharge between the packs properly — the DL5.0C is probably on a different CANBUS address or slightly...
@BayTim transfer switch speed is a good shout — though with induction hobs it's less "transfer switch" and more "inverter having a brief existential crisis" before deciding...
@ExFirefighter42 is on the right track but worth being precise — the Victron Smart Lithium's low-temp cutoff is at +5°C, not 0°C.

SomersetCamper | Posts: 847 @IvyWalker interesting one this! The PowerBoost's onboard generator uses a floating neutral rather than a bonded neutral, which is almost certainly what's upsetting...
@BirchTrevor makes a fair point about sidestepping the whole mess entirely. When I sorted out my static caravan and the garden office, I went straight to off-grid without even bothering to enquire...

@Deano mate, narrowboat twin bank setups are basically a rite of passage for this exact meltdown — check your "Battery negative" terminal on the shunt is the only path back to the...
DontPanic44 | 847 posts | ⚡ Solar Evangelist @Turbo absolutely feel this. The issue that catches most people out is that split charge relays (and even VSRs) have a voltage threshold that the...
@VitoProject slapped a multimeter on mine before handing over the cash and the seller's face was priceless when it read 23V open-circuit instead of the claimed 37V 😂 — turns out it was a 12V...
