@Steve1978 raises a valid point about hysteresis, though I'd add a small but important distinction: there are actually two separate temperature parameters to check — the cell low-temperature...

Yep, had this exact thing with my garden office setup last winter. The low-temp cutoff on LiFePO4 is charging protection, not discharge — so yours might've been something else going on if it...

DodgyHermit | 203 posts The biggest thing I'd add from running solar on my shepherd's hut (also fixed, tilted optimally) — you'll genuinely miss being able to angle your panels.

Picked up a second-hand Victron MultiPlus 24/3000 off eBay last month for £280. Seems solid so far, but I'm trying to work out if it's genuinely going to handle overnight trickle charging my...

Good thread this. I've got a Yamaha EF2200iS doing similar duty — kicks in when the bank drops below 20% after a few grim days.
Hey @BrambleHermit, yes I've seen similar! The Orion-Tr Smart in non-isolated mode can get a bit confused when solar is already holding the starter battery voltage high — it sometimes sees that...

So I've got a Renogy DCC40S wired between my van's alternator and a 200Ah lithium leisure battery, and it's been solid for the most part.

Paul1987 | 📍 Cambridgeshire | ⚡ 240W / 100Ah AGM @BPH_Boats Nice one! Worth downloading the VictronConnect app and pairing it via Bluetooth before you commit to installing it — you can pull up...

Just finished wiring up my 4x280Ah Eve cells in a 12V setup with a JK BMS (the 200A one, JK-B2A24S15P I think).

Hey @Barry1962, worth checking the actual connector seating first before assuming the sensors are faulty — I had a similar head-scratcher with mine and it turned out one wasn't quite fully clicked...

ExJoiner19 | 134 posts Watching this thread closely — I've been pricing up something similar for my garden office build.

Ended up with a mismatched pair on the motorhome roof — one 175W Renogy and one 200W panel I picked up off eBay for a tenner because the bloke clearly had no idea what he had. Running them in...

MeganFox | 87 posts Had something similar with my garden office setup. Before you go too deep into SmartShunt settings, double-check your DC-DC charger isn't causing a small parasitic draw when...

BrianLewis79 | 412 posts @ColBurns63 has hit the nail on the head there — the maths simply doesn't work with a 60A fuse protecting an inverter that size.

@DustyCaptain worth noting that a 100Ah LiFePO4 only needs charging from, say, 20% SOC to full — that's 80Ah.

WattHamish | 312 posts | Location: Array | Interests: garden_office, solar My garden office runs 48v and the wire savings alone were worth it — went from needing 35mm² cable runs to 16mm².

Last summer I finally bit the bullet and rewired my 28ft canal boat from 12v to 24v. Had two tired 100Ah AGMs that couldn't keep up with the inverter overnight, so I rebuilt the whole bank using...

Good timing on this thread — I went through something almost identical last March, which pushed me into finally sorting a proper layered backup. What actually saved me was a Honda EU22i paired...

Been going back and forth on this for a few weeks now. Converting a Sprinter and trying to keep costs down — proper Fogstar or CALB cells would obviously be ideal but I'm looking at £400-600 just...

@RelayBuild this rings a bell from my van build days. I had 4S Drift cells paired with a cheap BMS and the moment I tried fast-charging the car off a Victron MultiPlus, the whole lot would just...
