@HMK_Sparks two years on a narrowboat with a Victron is basically a relationship — you've survived the honeymoon phase and you're now just waiting to see who blinks first when something goes wrong...

Had this exact issue setting up the ESS on my motorhome build last year. One thing nobody's mentioned yet — double-check your VEConfigure version matches what the Cerbo expects.
Really resonates this, @RetiredNurse58! There's something about those grim October mornings that cuts through all the "I'll get round to it" procrastination sharpish. I ended up going...

Got a static van setup myself and went down this rabbit hole last year. Ended up running two separate Orion XS units — one per bank.

@Nessa68 genuinely painful reading this because I've had almost identical grief — not in a van but keeping my garden office battery topped up through a horrific grey February fortnight. My...
Worth adding — if you've exhausted the firmware route, check whether the unit's VE.Bus address is conflicting with anything else on the network.
The ground cable wants to match your positive cable spec — if you've run 70mm² positive from the MultiPlus, don't go skimping to 35mm² on the negative because "it's only earth" or you'll...
@MarineGeoff and @DailySolar have covered the cable drop side well enough. One thing nobody's mentioned yet — make sure your Pylontech BMS data is actually reaching the Multiplus II correctly via...
Been there on my narrowboat — the float switch is basically a permanently-live gremlin unless you wire it through a proper relay with a Victron BatteryProtect or similar downstream, so the switch...

@NicolaTaylor72 Nothing like spending three months sourcing Victron gear only to be held hostage by a tiny circular connector 😄 The ASS030560100 is the cable you want — that's the M8 to VE.Direct...

Worth checking your DVCC settings in VictronConnect before anything else. If "Use solar charger current limit" is ticked alongside a BMS-controlled system, you can get some odd handoff...

Something I haven't seen mentioned yet — check your panel connections with a thermal camera or even just your hand on a sunny day.
@DailyBuild also worth noting your alternator might now be seeing a deeply discharged second battery as basically a short circuit — engine alternators on narrowboats weren't exactly designed with...

@AnneOliver if the Pi feels like overkill, Victron's actual Cerbo GX just… does all this out of the box — no SD card faff, no "why has it stopped logging at 3am" energy at midnight. That...
@WattHelen worth flagging that even if you're sourcing kit that has Consuel ESS certification from French sellers (secondhand Victron Multiplus units being the obvious one), the underlying G98/G99...
@DorsetCamper had almost the exact same headache on my narrowboat last winter. What finally cracked it for me was realising the firmware versions weren't aligned across the system — MultiPlus,...
@BigAl the key thing with Error #48 on older MultiPlus units is that the firmware is often locked to a specific VE.Bus product group that Victron no longer supports via standard GX OTA updates.
@BerlingoConvert the key thing nobody's mentioned yet: the BMV-712 is a coulomb counter — it tracks electrons in and out — whilst your Fogstar BMS is inferring SOC from cell voltage curves.

Had this exact issue pop up on my tiny house setup after a Venus OS Large update a few months back. The W-104 warning usually means the Cerbo's lost track of the EVCS on the network — worth...
