Running a small chest freezer in my van conversion and trying to work out if my 200Ah Fogstar Drift is going to cut it overnight without solar input. The freezer is a Alpicool C15 (15L) — pulls...

@KentVanLifer had this exact same phantom absorption issue on my cabin setup — ended up being a dodgy crimped connection between the battery terminal and the Victron's sense wire, adding maybe...
Been following this one with interest because I had something similar on the boat last winter with my SRNE hybrid and a JK BMS combo. What I found — and this might not be your exact issue — is...
@SmartSolarNerd capacity test is the gold standard but there's a quicker sanity check first — verify your BMV-712's shunt is actually seeing all your load and charge current.
Had this exact head-scratcher with my static caravan setup last summer — Victron SmartSolar 100/20 paired with a Fogstar 100Ah LiFePO4, and the thing was smugly declaring absorption after pulling...
Really enjoyed reading through this thread. My narrowboat has a pole-mounted turbine using a permanent magnet motor salvaged from an old Miele — those German machines often have beefier magnets...

Been pondering this one for my van build actually — got two Fogstar Drift 100Ah LiFePO4s running in parallel via busbars and wasn't 100% sure where to drop the Smartshunt in. From what I've worked...
Not had a PowerMan specifically but this rings true for my static caravan setup. Quick question though — when it freezes, does the inverter itself keep running or does everything drop out?
@CamperEwan worth checking the input voltage drop as well — when the engine's warm and the alternator's been running a while, if your cable run is long or undersized you can get enough voltage sag...

@PhilJackson absolutely nailed it with the "software having an existential crisis" description 😄 Worth adding the actual fix though: in VEConfigure, check your AC Input current limit per...
Interesting setup — Jiabaida BMS units are fairly capable for the price point, though I'd want to know what cell chemistry you're actually running inside those packs.

Relevant to anyone sourcing Victron kit through third-party European suppliers — worth a read before you commit. I had a similar headache last year when I was speccing up the system for my garden...
Same thing happened to me last spring with my Honda EU22i after it sat unused from October through to March.
Running my narrowboat through winter means I'm pretty paranoid about keeping a small chest freezer going when I'm moored without hookup.

Good thread — had almost this exact puzzle on my boat last year. Once I'd ruled out VE.Can (as @VE_Boats and @WezFrost suggest), the culprit on mine turned out to be VEConfigure — specifically an...
@VanJim had this exact argument with my narrowboat setup — BMV drifts like a drunk on a towpath if you never hit 100% to let it resync, whereas the BMS is just watching cell voltages and making...
ThistleTel | Posts: 2,089 | Location: Array @DucatoLife the Fogstar Drift 48v units use an integrated BMS already, which answers a few common questions before you even ask them — worth noting...

@ZoeGrant this is almost certainly an absorption time setting that's too short, or your absorption voltage is set too low for your battery chemistry. On my boat setup with Fogstar Drift cells, I...
Good timing on this thread — I've been running a Shoreline 60L chest freezer on the boat for two seasons now, so can offer real-world numbers rather than theory. My setup is similar to yours and...

Been having exactly this with mine on the narrowboat — fitted an Orion XS 50A about three months ago and on longer cruising days (4+ hours on the engine) it'll drop out maybe two or three times.
