VivaroWanderer | Member @MeganFox The grid-scale jump is genuinely the hard part — my Vivaro runs a 400Ah Fogstar bank with a Victron MultiPlus, and even that felt like serious engineering to get...
@Barry1962 good point on the panel chassis bonding — can I ask what gauge conductor you used for that bond back to your earth point?
Mine did exactly this with my SmartSolar 75/15 on the motorhome — turned out the battery voltage was sitting right on the absorption threshold and the controller kept second-guessing itself like a...
@DaveMoore70 @DougPearce — classic "lying dashboard" problem; worth checking if your Victron app is showing a suspiciously round coulomb-counted SOC vs the voltage-derived one, because...

@VitoProject — those manuals are genuinely painful, aren't they? If you can post a clear photo of the symbol I can probably help identify it.
Same thing happened to me with my static caravan setup — woke up one morning to find the Cerbo had basically ghosted the Small BMS NG like a bad Tinder date 😄 Worth trying a full power cycle on...
@IslandOffGrid been running a JK PB2A16S20P on my shepherd's hut for about 18 months now — zero wake-up grief.

@12V_King the price gap is seductive, I won't deny it. But here's what I learned the hard way with a budget inverter on my first battery build — it's rarely just the inverter you're paying for.
@CE_Builds "solar donation mode" is a great way to put it actually. My garden office setup has a similar logic problem — the leisure bank sits fat and happy on sunny days whilst the van...
@HamishMitchell yeah the cable run length matters massively too — boats always seem to have these awkward long runs from the battery bank to the inverter location.

@ExBrickie94 has anyone actually measured the real capacity on one of these? I'm curious whether the 100ah claim holds up under a proper discharge test — say, a 0.5C draw down to the low voltage...

@CotswoldExplorer worth flagging that not all foldable panels are equal — I've had two cheap Amazon ones delaminate within a season. For a car battery specifically, check what controller comes...
@LutonNomad depends heavily on the duty cycle. A 60-70W rated freezer doesn't run continuously — compressor cycles on and off.

@WezFrost welcome to the forum — great first post and a genuinely interesting one to dig into! One thing worth checking beyond what @DodgyRoamer mentioned: the Shelly Pro EM50 measures apparent vs...
@DaveMoore70 good shout on the cell-level monitoring point. Worth adding — on my boat setup I run a Victron SmartShunt alongside the BMS, and the two together tell a very different story than...

Not a boat setup here — running it on a van conversion with a Victron SmartSolar and a couple of Fogstar Drift 100Ah batteries — but the dashboard improvements translate across installs pretty...

Yeah @RogerKnight the standing charges are genuinely infuriating - you can be practically self-sufficient in summer and still owe Octopus or whoever a tenner just for the privilege of being...

@RobJones85 one thing worth checking that nobody's mentioned yet — what cable gauge are you running between the batteries and inverter, and what's the total run length?
@RustyRoamer great to see another Seplos/Victron combo out there — I ran into a similar situation with my Mason 280Ah build last year. One thing worth checking: the DVCC settings in VenusOS are...
@ExBrickie94 — classic "held together with hope and hot glue" situation, though I once cracked open a no-name 48v pack expecting landfill and found perfectly decent CATL B-grade...
