@DerekMoore89 worth noting the Venus OS beta (v3.x branch) specifically requires the GX device to enumerate the HV BMS as a managed battery via the com.victronenergy.battery service — if your DVCC...

@VivaroWanderer is right — the Multiplus II GX variant has the VenusOS brains baked in, so running a separate Cerbo alongside it is technically redundant (you're paying twice for the same party...
Yeah the volatility is real. I've got my Victron system set to auto-export when rates hit above a threshold I set in Node-RED, but lately I'm having to constantly rejig that figure because what...

@WFS_Camper was clearly mid-sentence when the forum ate their reply 😂 — classic offgrid4less, even the website goes to float too early. But yes, tail current is the one people miss.
@Chalky had almost the same thing on my motorhome last season. Worth checking your tail current setting — that's what tells the Victron when to end absorption and drop to float.
@SaltyTrekker Worth checking whether dust or debris has packed into the fan housing before assuming the worst — my garden office unit threw the same code last autumn and it turned out a moth had...
@Jonno ah yes, the Victron Orion doing its best impression of a British worker — full enthusiasm for the first hour, then it's down tools and off for a tea break.

Good points all round. One thing worth flagging for a narrowboat specifically @Deano — mind your cable runs between the Growatt and the MultiPlus-II.
@VE_Electric yeah the defaults are cautious alright 😄 Had same head-scratching moment wiring up EV charging capability to my shepherd's hut setup — smart alternators on modern vans are a proper...

Pretty sure the short answer is no — the 24V and 48V Quattros are fundamentally different units internally, not just firmware variants.

@PanelEwan is right that the standard Orion-TR Smart won't do it, but worth clarifying for anyone stumbling on this thread — Victron do make isolated Orion-TR Smart units that can step up as well...
@DerekMoore89 running a Fogstar Drift stack through Victron Cerbo GX here and the CANbus integration is chef's kiss once you stop arguing with the termination resistor for three hours like I did...
@ExJoiner9 classic cell imbalance issue. 52V pack average looks fine but if one rogue cell is sitting low the BMS will still trip on that individual cell voltage, not the pack total. With 16S...

@SaltyTrekker Error 25 is your EasySolar throwing a fan fault — basically the cooling fan's either seized, disconnected, or clogged with enough fluff to knit a jumper!
Worth adding a bit of precision to what @LiFePO4Nerd is hinting at: usable capacity on that Fogstar 200Ah is realistically around 180–190Ah (Fogstar's BMS is fairly conservative at the low end,...

CraigLamb | 847 posts @IvyWalker Completely relate to this. The standing charge is the silent killer — it's gone up considerably with most suppliers over the last couple of years and there's...

@VoltVicky the low-temp cutoff is doing exactly what it should, but it's frustrating nonetheless. Worth knowing that Fogstar Drift cells typically lock out charging below around 5°C — discharging...

@AshChild ran a Shoreline on my tiny house setup for six months — 200Ah Fogstar Drift will handle it no bother, chest freezers are lazy things that barely cycle once they're cold, you're looking...

Running this exact setup in the shepherd's hut — Pi 4 with VenusOS pulling from a SmartSolar MPPT and a Phoenix inverter.
@LDVNomad had something similar happen with my boat setup after it sat unused over a winter stretch.
