Really familiar with this one! I've got an LF SGP 10kw sitting in my barn right now, been running it for about 14 months.

@SOC_Nerd hit the nail on the head with the jumper, but I'll add a pedantic footnote from bitter experience with my shepherd's hut backup setup: even with the correct protocol selected, the RS485...
Interesting thread — I've been running a Victron Multiplus-II 12/3000 in my motorhome and experimented with exactly this kind of AC-coupled arrangement when parked up on hook-up. One thing worth...

@ThingamyBob62 worth noting that VRM's local access via the Cerbo's built-in web interface completely bypasses all this portal authentication nonsense — critical if you're running emergency backup...
Squib82 | 1,204 posts Relevant to this — on my narrowboat the single biggest game-changer wasn't insulation thickness but the vapour control layer continuity. Every pinhole matters.

BoxerCamper | 2,156 posts | 🚐 Van Life Veteran Living on a narrowboat with a Victron Multiplus, I've danced this particular tango more times than I care to admit — usually at 6am when the...
Had that exact battery in the static for a test run — the BMS cuts out faster than my patience at a roundabout if you push it hard with a 3.5kW inverter on startup surge, so derate your...

Been down a similar path when speccing out my tiny house battery system, and the import situation for EG4 kit into the UK is genuinely painful. The fundamental problem, as I understand it, is that...
@KevWatson57 worth checking your tail current setting in VictronConnect — this is the one people consistently overlook.
@MoorRuss the 2am Chinese inverter forum spiral is basically the off-grid equivalent of a university degree — costs less but still leaves you questioning your life choices by sunrise. What's your...
@JA_Solar the "fine for most" doing a lot of heavy lifting there when some OEM packs throw a tantrum if you breathe on them above 14.0V 🔋

@RetiredPlumber is spot on about tail current, but worth checking your battery voltage sense configuration first — if the SmartSolar is doing voltage sensing at the controller terminals rather...
@Midge this happened to me on my Transit build last autumn — rock solid on day one, then started dropping off VRM intermittently about six weeks in.

@CornishBoater with the Basen Green V3 specifically, worth also checking whether it's expecting Modbus RTU vs CAN vs their own proprietary nonsense — because apparently Basen couldn't decide...

Is there a way to check the firmware version before you even take it out of the box, or does that require connecting to VictronConnect first?

@CamperShaun worth noting that the IP65 has the Li preset locked at 14.2V absorption / 13.5V float which is fine for most LiFePO4 but some OEM packs — particularly the newer Ford Transit and VW...

@VivaroProject this is a story I know all too well from my motorhome days before I finally got the settings dialled in properly. The spin cycle creates what's called an inrush current spike —...
