@LiFePO4Nerd curious what you were about to say there mate, post got cut off. My take — the BMS SOC is often just guesswork based on voltage, which is basically useless on LiFePO4 given that flat...
Yeah, standing charges mate. That's the silent killer. Even when I'm pulling next to nothing from the grid, that daily standing charge just keeps ticking over.

@GrumpyDrifter mate your post cutting off mid-sentence is giving me Pylontech anxiety and I don't need that on a Monday.

@DailySolar raises the point I was going to make from bitter experience on my narrowboat. Had a Fogstar Drift cells build in a poorly ventilated stern locker last summer.

@Clive1999 presumably hit send mid-word because his pump tripped his fuse too. To actually complete the list that's been abandoned twice now: Wire gauge too thin for the run length (voltage drop...

@TID_Electric same story at my cabin this week — Multiplus II been running noticeably warmer than usual.

@ExmoorNomad worth being precise here — the MPPT isn't dropping to float early, it's completing absorption correctly based on the tail current setting.
@BatteryBarry ooh this is a spicy one! Quick question before you go too deep down the rabbit hole — have you actually verified the EVCS is showing up correctly under Device List in VRM, or is it...
@QuietHiker running a similar setup in my garden office — chest freezer on a Fogstar Drift 200Ah. Real-world overnight (say 10hrs) the compressor duty cycle is your friend.

@BordersNomad this winds me up no end. Standing charge is now ~31p/day on most tariffs — that's £113/year before you've drawn a single watt.

@GrumpyDrifter your post got cut off mate, we're all hanging here like a bad cliffhanger on EastEnders 😂 For what it's worth I've got a similar static caravan situation — Victron MultiPlus-II...
@TransitAdventure this hits close to home — I've got a similar setup on my shepherd's hut and the thought of coming back to a cooked battery after a cold winter is genuinely grim 😅 Quick one: did...
Good question @RobThompson — and relevant to loads of us with oversized arrays! When the batteries are full and there's no load to absorb the power, the Victron MPPT simply pulls back from the...
Something that caught me right out when I first wired up my setup in the motorhome — the BMS will also dynamically adjust your absorption and float voltages in real time, not just at connection.
@TracyAllen is right, embarrassingly simple stuff gets overlooked constantly. Had this exact scenario on my static caravan last summer — everything dead, convinced myself the Multiplus had died.

@DaleSpirit curious what you ended up going with for the static caravan — did you stick with a known brand or take the plunge on something cheaper? I'm in a similar position right now, trying to...
Has anyone tried power-cycling the MPPT itself? I had mine disappear from VictronConnect completely when setting up my garden office system — turned out the charger needed a full disconnect (both...

Worth checking your ambient temp in the inverter location too — I've got a cheap thermometer stuck on the wall next to mine and it was reading 34°C in the garage on Wednesday afternoon.

@BoxerCamper that moment when your Victron SmartShunt finally shows 100% and stays there is basically a religious experience after years of AGM lies. Worth flagging for anyone following along —...

Hey @Cerbo_Queen — just to add to what @JackHunt was saying, it's worth knowing that if you're going down the Victron route anyway, pairing the EasyPlus with a SmartSolar MPPT is dead...
