@Nessa73 raises a good point on adaptive absorption — that caught me out badly on my narrowboat the first winter I had the system running. What nobody's mentioned yet: check your tail current...
@CaddyProject and @RobBennett93 have covered the frequency angle well, so I'll add something slightly different — check your AC input current limit setting in VE.Configure.
@CliveBaker genuinely curious where you're going with that — what's the "legitimate" use case you're hinting at? My gut says the only sensible option is keeping it completely isolated —...
My static van's basically a glorified crisp packet so I feel this pain on a cellular level. Biggest bang-for-buck I found was attacking the air leakage before touching insulation proper —...

@RobJones85 this is a known quirk with the Cerbo GX firmware when ESS is configured alongside a MultiPlus-II.
Been noticing something a bit odd with my Multiplus 12/3000 in the motorhome lately and wondered if anyone else has seen this. When it first kicks in from cold, efficiency seems fine — but after...
So my old inverter finally gave up the ghost last month — seven years of faithful service powering my garden office, then one morning: nothing.
@CamperDan nice setup. I went a slightly different route — Pi Zero 2W running Venus OS Large directly, so it is the GX device rather than just logging from one.
BorderCamper | Posts: 287 Really interesting thread this — I've been wondering about using vehicle-to-load exports for my van build so following closely. Quick question for @BirchLover and...
@DefenderAdventure all valid points but nobody's mentioned the obvious — pre-chill your food before it goes in the fridge, not after, saves your battery doing the heavy lifting from warm.
Running a small chest freezer off-grid on the narrowboat and trying to work out if my 200Ah LiFePO4 (Fogstar Drift 12V) will actually cope overnight without flattening itself. The freezer is a Lec...

@Cleggy not a dumb question at all — but the answer depends entirely on which gap. Historic lime-pointed stonework with small voids? Leave it, it's doing vapour management work.

Been dealing with something similar on the boat recently and thought I'd share in case anyone else has hit this wall. Running a Victron Multiplus-II 48/5000 paired with a Cerbo GX and a 15kWh...
Been running a similar setup at my cabin for the past couple of seasons — Victron SmartShunt, MPPT 100/50, and a 200Ah LiFePO4 pack (Fogstar Drift in my case rather than the Superpack, but the...

Been running one of these in the van since last spring and honestly it was fine all summer — no complaints. Then November hit and I started getting some weird behaviour.
@RetiredEngineer86 nothing builds character quite like explaining "no but the warranty is American" to a HMRC officer who doesn't care — Fogstar or Fogstar Drift for similar capacity...
@LiFePO4Nerd is right that duty cycle is the crux of it, but worth adding the usable capacity angle too. A 200Ah LiFePO4 (Fogstar Drift or similar) at 12V gives you ~2.4kWh.

Really useful thread this — I've been eyeing up exactly the same setup for my static caravan! Quick question though: does the ambient temperature of where you're storing the freezer make a big...

Good thread — lots of useful stuff here already. One thing I'm curious about: has anyone actually approached Victron about this use case?
Been running a Pi 4 (2GB) connected to my Victron Multiplus-II via a VE.Bus to USB interface for about 18 months now, and it's been rock solid for local data logging. I'm using VictronConnect data...
