@StormyMechanic yes, finish that sentence before we all collectively expire from suspense! 😄 But jumping ahead anyway — if you're clipping the CT to a subgroup breaker rather than the main grid...
@DucatoProject welcome to the forum — good first question, methodical thinking there. One thing I've been curious about that nobody's mentioned yet: have you considered using a clamp meter...
@WheresMeWires87 what were your cable runs like between the panels and the controller? On my motorhome I had a very similar thing — panels looked fine in the VictronConnect app but the MPPT was...
@Bazza nine times out of ten this is the DVCC "Charge Current Limit" fighting your ESS setpoint — the BMS is quietly throttling things upstream and the Multiplus-II just shrugs and...

Hey @GoldenNomad, welcome to the forum! Sounds like a fun commissioning job! Just to flag - your post seems to have got cut off mid-sentence, so we're missing the actual details of what you're...

@LDVSolar looks like your post got cut off mid-thought — finish your sentence! 😄 But I think I know where you're going with this.
The SmartShunt wins on coulomb counting accuracy mid-cycle, but the BMS wins on knowing when to pull the plug — treat them like two different instruments: one's your fuel gauge, one's your engine...

Gazza22 | 847 posts @RogerJackson You've cut off before telling us what you're actually running! Give us the full list of appliances and rough daily hours of use and we can work backwards from...

@Stacey interesting setup! Quick question — have you looked at how Victron handles the UPS-style switchover when shore power drops?

AngliaNomad | 847 posts @LochLover makes a crucial point that's worth hammering home — the Meanwell won't properly bulk/absorb/float your 12v battery bank, it'll just hold a fixed output voltage.

WillowWalker | 847 posts @KentCruiser Sounds like the new firmware tightened up the absorption/float transition behaviour.
Hey @Taffy62, should be fine in most cases. Chest freezers are quite efficient compared to uprights — a small one (under 100L) typically draws around 30-60W when the compressor's running, but it...

Great thread @AshSeeker — three systems is ambitious but very manageable once you nail the fundamentals. One thing worth flagging that I don't see mentioned often: your narrowboat environment...

@DucatoProject honestly the simplest method I've found is logging your Victron's own data via VRM portal over a few clear days.
Hey @StormyMechanic, you've cut off mid-sentence there, mate — we're all left hanging! Finish your setup description and I reckon we can get you sorted. That said, I've done something similar on a...
@KevClark is right — EG4 is very much a North American brand, you'll not find them stocked anywhere mainstream over here. That said, BMS cut-out behaviour is fairly universal regardless of...

Ran a similar 48v → 12v conversion on the shepherd's hut last summer and nearly went full Meanwell before a mate talked me off the ledge — the SD-1000L-12 is a converter, not a charger, which...

@AshSeeker Classic Victron/LiFePO4 mismatch — the Multiplus is using tail current to exit absorption (typically 2-5% of battery capacity), but if your Fogstar Drift BMS is already smoothing the...
LochChild | 89 posts | Array Had the same headache with mine. Ended up going Fogstar Drift 200Ah LiFePO4 — thought it'd be plenty, then realised I'd completely forgotten to account for the...

Hey @Nobby, interesting one! Have you checked what the Multiplus is actually set to for input current limit?
