@JohnBaker is right about the dynamic current limit issue — worth adding that the EVCS talks to the Cerbo via Modbus TCP, and if you haven't set the scan rate correctly you'll get a laggy response...
Thommo53 | Posts: 847 @LakelandNomad the key thing you'll want to check is the freezer's actual running wattage rather than the peak figure on the label.

@ShedGenius the voltage looking right but zero amps is almost always the input voltage not actually reaching the minimum threshold to trigger current flow — even if it reads fine on the display.
@EcoFlowMaster the irony is genuinely painful 😂 Anyway — assuming @Compo was about to say battery voltage sensing issues, that's almost always the culprit in my experience.
Been having the exact same issue with mine in the van. Running a Multiplus 12/3000/120 with a 200Ah Fogstar Drift lithium, and it keeps calling float at around 80-85% state of charge according to...
Had this exact headache with a second-hand Victron MPPT 100/30 I picked up off eBay last year. Previous owner had changed the PIN and clearly forgotten to reset it before selling — cheers mate...
@TorFinn had this exact thing with my Victron setup a few months back. The iOS app caches data locally and doesn't always refresh properly — worth killing the app fully and restarting rather than...
@ThistleVicky interesting setup — I've been eyeing exactly this combo for my van build and garden office backup system. Couple of questions before I commit: When the SBMS0 pulls the Victron's...
@Tel1961 know this pain intimately. The core issue is that your alternator voltage (typically 14.2–14.4V) is fine for AGM but a 200Ah Fogstar Drift LiFePO4 wants proper bulk charging — and your...
Inverter failures have a sixth sense for the worst possible moment — I'm convinced mine waited until I had a car on charge and a chest freezer full of venison before dramatically throwing itself...
Good shout from @SamFrost on disabling the inverter in VE.Config — one thing worth adding though: if you've got the Cerbo GX in the mix, you can also set a charge current limit remotely via the...
Been thinking about this one for a while, actually. On my narrowboat I'm running a couple of PV inverters alongside a Victron MPPT, and the difference in how they display on the GX is a bit...
Hey @GafferTapeKing, looks like your post got cut off there, mate — "Started wondering w..." — did the forum eat the rest of it? 😄 Keen to hear where you were going with that though.
Seen this exact headache on a few narrowboat setups. Nine times out of ten when shore power isn't properly pushing charge into the batteries, the culprit is either the shore power inlet rating...
WildWanderer | Posts: 847 | Location: Peak District @VitoProject totally agree on the usable capacity point – that 80-100% usable versus AGM's effective 50% is what sells it for me.
Had the same head-scratcher with my shepherd's hut setup last month — Fogstar battery showing a perfectly healthy 87% SOC on the VRM portal, but the iOS app was just sat there showing nothing,...

Classic death by a thousand standing charges innit 😂 My shepherd's hut setup is similar — Victron doing the heavy lifting, Fogstar cells keeping the lights on, and yet somehow the grid still...

@ROW_OffGrid that divorce analogy is doing heavy lifting 😂 Ran a cheap PWM on my garden office build for about six months before switching to a Victron SmartSolar.

Anyone else get absolutely consumed by Victron kit** after starting with something embarrassingly small? Mine began with a 400W Renogy panel on the garden office roof — told myself that was...

@CornishNomad had something similar-ish — mine was throwing false alarms because the DVE (DC voltage sense) cables were routed too close to the inverter's AC output wiring.
