@Wez1961 similar-ish setup here but I've gone a bit overboard adding EV charging into the mix via a small Type 2 socket — not fast charging, just a trickle feed for the ebike.

SomersetCamper | Posts: 412 @LisaStewart71 One thing worth checking that I haven't seen mentioned — are your cells actually at 2–4°C or are they warmer inside the caravan?

@DaveMoore70 the "optimism and a cursed cron job" setup is carrying more off-grid systems than anyone would care to admit, genuinely... Running something similar on my narrowboat — Pi 4...

@Spider6 my garden office panels spent most of last week generating enough electricity to power my disappointment, and not much else.

Been running a similar setup in the van for a couple of years now. After getting caught out near Bamburgh during a particularly grim January storm — no shore power, temperatures dropping, the...

Really useful thread this. @RogerJackson one thing I've been wondering about for my shepherd's hut setup — have you looked at whether VRM portal connectivity is actually necessary 24/7?

Running something similar in my shepherd's hut actually, though the principle's identical for a house setup. One thing nobody's mentioned — standby power draw matters more than you'd think over...

@SolarDoug worth noting they top-balance beautifully out of the box — mine came remarkably close already and only needed a short absorption session before I could assemble the pack.

Converted my narrowboat into a floating shepherd's hut situation (long story) and now I'm trying to charge my Leaf from a Victron MultiPlus 2000 running off 400Ah of Fogstar Drift LiFePO4 — it...
@TelHall one thing nobody's mentioned yet — if you're pulling both sources into Home Assistant, spend the time setting up a proper energy cost template sensor that calculates your actual import...

Had this exact issue on my setup. Worth checking your AC input current limit too — if the MultiPlus thinks shore power has appeared when the alternator spikes, it can get confused about what's...

PartnerCamper | 312 posts | ⛵ Member My boat batteries pulled the exact same stunt last February — nothing like a 3.18V resting voltage to make you question every life decision you've ever made at...

Ran one of those exact blue-cased units on my narrowboat for about eight months before upgrading to Fogstar Drift cells.

@DriftGal same boat here, well, same van. Had AGMs in my old motorhome for years and the weight alone should've pushed me to lithium sooner.
@ForestDweller — something worth adding that nobody's mentioned yet: even when your BMS does allow charging in the cold, you're potentially causing lithium plating on the anode cells if you're...

BurnShaun | Posts: 312 @RhysLee78 Something worth trying that hasn't been mentioned yet - have you looked at running separate BMV-712s on each bank rather than relying on the Cerbo's built-in SOC...

@MoreTeaVicar I've been through two proper Scots winters with panels on my cabin roof and the difference between surviving and not is entirely down to the mounting hardware — not the panels...

GeorgeSmith97 | 47 posts @Rodney58 Yeah, the SOC display on those cheap Dalys is essentially guesswork unless you've done a proper capacity calibration cycle.

What @12V_King and @KevWatson57 said about series vs parallel is spot on, but one thing I'd add from my own static caravan setup — bypass diodes only partially mitigate the issue, they don't...

@VitoProject this is almost certainly a PowerAssist configuration issue rather than a genuine overload.
