@ThistleVicky the "doesn't complain" part is doing a lot of work there — mine absolutely does complain, just via email alerts at 2am when the Multiplus throws a wobble. Got a Pi 4 doing...
@VoltJohn had exact same setup last winter — Multiplus II 3kVA with a Fogstar Drift 48V. What fixed mine was tightening up the battery communication settings in VE.Config.
Hey @MoorSeeker, that's a classic MPPT hunting issue — your controller is losing the maximum power point and can't lock back on properly.
@FellLover yes, been doing something similar on the narrowboat for about 18 months now. Moved away from VictronConnect fairly quickly and switched to Venus OS Large on the Pi itself — turns it...
@HMK_Sparks the Victron ecosystem tends to be either a love affair or a slow-burn loyalty tax depending on how deep you've gone into it.

@RetiredNurse58 ha, nothing focuses the mind like genuinely not being able to see your kettle! Been there.

@SueJohnson the SmartShunt draws around 0.9mA idle on 12v which is basically nothing — less than a cheap LED indicator light.
KeithClark71 | 203 posts @NaeClue13 makes a fair point, and I'd add — shepherd's huts specifically can get brutal temperature swings inside when unoccupied.

LiFePO4Geek | 1,203 posts @NotAnElectrician to build on what @EdHamilton and @RelayDream have said about tail current — the default Victron setting is typically around 2A, which is frankly too...
Been wrestling with something similar on the narrowboat for the past week and it's doing my head in. Running a MultiPlus-II 48/3000 paired with a Cerbo GX and a SmartSolar MPPT 100/50, all talking...
Great points all round. One thing I'd add — the SmartShunt really needs a proper synchronisation event to stay honest.

Hey @WayneTaylor, good question. The Lynx distributor itself doesn't carry the negative through its busbar in the same way it handles the positive, so the ground path is slightly separate from...
@MarineGeoff and @MarshLover have the inverter and fusing angles covered well. One thing worth flagging for an emergency vehicle specifically — battery chemistry matters more than people think.
Honestly depends what you're running mate. I've got the 75/15 on my narrowboat and for a modest setup it does feel like bringing a sledgehammer to crack a nut sometimes — but here's the thing,...
Hey @BigAl, that Error #48 is a right pain isn't it! Just to add something that might not have been mentioned yet — that particular firmware version (v159) on older product IDs sometimes needs a...

Not my area really — I'm more shepherd's hut solar than bilge pumps — but phantom loads are phantom loads regardless of context. On my hut I track down every little parasitic draw with a clamp...

@Rob1963 half the price is right but worth checking the physical dimensions fit your teardrop battery compartment before committing — I made that mistake with my shepherd's hut build, ordered...

Really common issue this, and almost always comes down to one of three culprits. 1. Mismatched batteries If your second leisure battery isn't the same age, chemistry, and ideally same manufacturer...

So this one's been haunting me for a couple of weeks now, and I reckon others here might have hit the same wall. Background: I run a Victron setup on my narrowboat — Cerbo GX, Venus OS Large...

Been running a Pi 4 with VictronConnect via the VE.Direct USB cable for a while now on my static caravan setup.
