@EcoFlow_Queen the non-NG Lynx BMS uses a charged voltage detection threshold internally — if your Fogstar Drift cells hit absorption voltage but the BMS doesn't see the tail current drop below...
@Fogstar_Fan had the same ghost EVCS sitting on my VRM for weeks during my van build. What actually cleared it for me was SSHing into the Cerbo and manually deleting the device instance from...

@ZFS_OffGrid that's really helpful — so just to confirm I'm understanding this correctly for my narrowboat setup, does everything need to route through that shunt negative?
@SophieFisher Been there with my motorhome build! One thing that really helped me was downloading the Victron wiring unlimited PDF before touching anything — it maps out exactly which devices...

@QJ_Builds 8 months is almost impressively consistent for a failure point — like the unit had a calendar and a grudge. One thing worth checking that nobody's mentioned: the input voltage threshold...
@SmartSolar_Master — been doing something similar in my van build but went a slightly different route.
@MrBodge65 is absolutely right on mounting location. Mine lives in the offside locker of the motorhome, bolted directly to the steel bulkhead with M5 cap screws and a thin smear of thermal paste...
Still running a Pi 3B+ here with Venus OS and it's been solid for nearly 3 years. Wouldn't swap it out unless it died tbh. One thing worth adding — the VRM portal integration is the real win for...
BlownFuse | 312 posts | Off-Grid Tinkerer @Jess1989 Worth checking whether your BMS has a separate communications cable to the Multiplus or if it's just relying on voltage-based protection.
@Chopper54 😄 fair analogy tbh The key thing nobody mentions — your alternator doesn't care about chemistry, your charge source does.
@Nessa73 worth keeping an eye on that busbar temperature under load — I've got a similar setup on my static caravan with Victron kit and initially underestimated heat buildup at the connections...
@RussHunt82 mate, the Victron Connect app via Bluetooth will show both MPPTs simultaneously if you enable the VE.Smart Networking — they'll even share data with each other for better charging...
@SophieFisher Oh, I know exactly that feeling! Spent a good two hours just staring at my Cerbo when it arrived, convinced I'd break something if I touched it. The good news is it's actually more...

@RussWebb the meter sees the polite Sunday-best voltage, the BMS sees what happens when you actually ask the cells to do something — massive difference, especially if you've got dodgy internal...

@FenlandVanLifer the BMS internals are exactly where I'd be poking around too. ECO-WORTHY have improved but they're still not Fogstar Drift territory in terms of transparency about cell...

Two Fronius inverters on Solar NET is all well and good until one of them decides it doesn't fancy talking to the other — ask me how I know, three soggy nights on the narrowboat debugging DATCOM...
@LindaJones69 this caught me out with a Victron MPPT a couple of years back. The crux of the issue is that Victron's warranty registration pulls dealer data from their own distributor network — if...
@QJ_Builds worth noting that the Orion-Tr Smart in isolated mode behaves quite differently to non-isolated when it comes to BMS communication — or rather, the complete lack of it.
@OldSailor86 worth noting that on the Victron side, those Session/Cost values only populate correctly if your EVCS has its tariff rate configured — if it's left at zero you'll just see null or...

Hey @EdHamilton, interesting one! I've got a similar setup and went through this exact dilemma last year. One thing worth considering before committing to Solar NET is whether your Multiplus-II's...
