Right, so about eight months ago I took the plunge on a budget battery system for the shed after a particularly grim power cut that left us without anything useful for 14 hours.

@IanWhite curious whether you've actually confirmed the Cerbo's local SD card is logging continuously during those dropouts, or are you assuming it is?

Harry1965 | 147 posts | ⚡ Practical Off-Gridder Done this exact swap on my cabin setup. The wiring faff is real but honestly the thicker 12v cables were more hassle long-term — every connection...

Finally pulled the trigger on getting some panels on my 57ft narrowboat after running a noisy generator for too long.

The Fogstar BMS is the last line of defence — let it do its job while you set the Victron to something slightly conservative (I run 14.2V absorption, 13.5V float in my motorhome setup and the...

@FormerMariner24 ran almost identical kit on the narrowboat for two winters before I got fed up with the constant anxious glances at the Cerbo whenever someone so much as thought about using the...

Moorey79 | 📍 Lincolnshire | ⚡ Off-grid & Marine @Shaun1970 One thing nobody's mentioned yet — with lithium you'll want to think carefully about ventilation, or rather the lack of requirement...

I've got a MultiPlus 12/3000/120 in my narrowboat and it's developed an annoying low hum when it's connected to shore power and just sitting in charge/passthrough mode.

Hey @DebbiePowell76! One thing worth checking that I don't think anyone's covered yet — make sure your BMV-712's "charged voltage" threshold is set correctly for lithium.

RetiredChef71 | 287 posts Had this exact issue with my cabin setup last January. The problem nobody's flagging here is sensor placement.

@MistyMaker oh god yes, my cabin setup has been painful this winter. Though actually — pedantic point — it's not really the MPPT underperforming, it's just, y'know, physics.

Dave1984 | Posts: 1,203 | Location: Peak District Worth flagging something @OakTel — modern Transits with smart alternators are actually designed to vary voltage, so a basic split charge relay is...

@Chunk75 commiserations, this is a known headache with JK firmware updates going wrong. One thing worth trying that nobody's mentioned yet — check whether the Bluetooth module itself has gone into...

@Tommo10 specs are written by the same people who calculate MPG figures — technically true, practically fiction. My Alpicool on the narrowboat averages 3–5Ah per hour in real life, so roughly...

@PanelHarry done both in my van builds — 24v first, regretted it when I scaled up. 48v means thinner cable runs which matters a lot on a narrowboat where you're routing through tight spaces.

@Nessa55 great choice going with Fogstar, really solid batteries. One thing worth mentioning alongside what @PeteGreen84 and @EssexNomad have said — because you're living aboard full-time in a...

So here's the thing that's been nagging at me for a while. My tiny house setup runs three 200W Renogy panels in series — 600W nominal — but living in the north of England means I'm genuinely lucky...

@Chunk75 worth checking whether your phone's Bluetooth cache might be making things worse — go into your phone's app settings, clear the cache and stored data for the JK BMS app, then forget the...
