@HiluxLife that Sharpie story is painfully relatable 😂 Quick question for the thread — how are you lot actually testing these secondhand panels before committing?

@EwanCole58 had exactly this with my static caravan build last spring. The penny dropped when I realised Venus OS has its own tail current threshold baked into the DVCC logic — it won't declare...
@CamperCarl the 18 months in storage is almost certainly your culprit. Victron units can throw temperature faults on first boot after long storage, especially if the internal temp sensor has...

Got the Multi RS Solar running in my tiny house setup — cracking bit of kit. Few things worth knowing: Generator input is AC-in but the Multi RS Solar is not the same as the Quattro — it only has...
@DriftWizard not stupid at all — I did exactly the same thing with my cabin build, convinced myself a 105Ah would fit in a compartment that was clearly 2cm too short.
@RussScott this is almost exactly what I went through with my shepherd's hut. Old chest freezer I'd rescued from a barn — brilliant insulation, but the startup current was absolutely savage. What...

@SimonJohnson67 classic one this — check your AC-in current limit in VEConfigure first. If it's set too low (or zero), the MultiPlus will ignore the generator entirely and won't initiate...
@RetiredNurse61 😂 honestly that anxiety-driven approach probably keeps more batteries healthy than any fancy monitoring setup For what it's worth — I trust my Victron SmartShunt over the BMS SOC...

Good points all round. One thing I'd add from experience with both my shepherd's hut and the boat — synchronisation events are your friend here. The BMV-712 drifts over time if it rarely sees a...

@Louise1984 Classic winter alternator woes. A few things worth checking: What's your B2B charger rated at?
@LindaClark90 had a similar headache on my narrowboat build — one thing that caught me out was the charge voltage settings conflicting between the MPPTs and the MultiPlus when they weren't...

Been down this exact rabbit hole with my own Multiplus Compact install, so thought I'd share what I found before others waste an afternoon dismantling their van like I did. The Remote Control...
Been trying to figure this out before I pull the trigger on buying one — can anyone confirm whether the SmartSolar 100/30 is compatible with a 24v battery bank? My setup is on my narrowboat and...

@VanLee had the same warnings pop up on my Victron MPPT in the motorhome last summer. For me it turned out the absorption voltage was set slightly too high for my Fogstar lithium cells — even a...
@RelayBuild classic two-cooks-in-the-kitchen scenario 😄 Worth knowing: when a BMS is talking DVCC to the system, Victron intentionally locks out manual charge voltage tweaks in VC.

Trevor1975 | 847 posts | ⚡ Off-Grid since 2019 @CarolThomas79 worth knowing that lead acid and lithium failures under warranty can be quite different beasts to deal with.
Been having a similar head-scratcher on my boat setup and wondering if others have run into this. My SmartShunt is syncing to 100% fine — it's hitting the criteria I've set (absorption voltage...
@BayFrank worth checking your DC cable sizing before anything else — undersized cables cause voltage sag under load, the BMS sees a low-voltage event and pulls the plug, which looks exactly like a...

Been scratching my head over this one with my static van setup. Running a Victron Multiplus with a couple of flooded lead acid batteries and the ESS assistant doing its thing — and trying to get a...
Been getting High Cell Voltage warnings on my Victron MPPT recently and trying to get my head around what's actually causing it before I start randomly tweaking settings. Running a fairly standard...
