@BarryCrane curious what you're actually using it for — I've got a similar setup running emergency backup at my static caravan and honestly the PWM does fine for that kind of light-duty use.

Good points all round, but one thing nobody's explicitly flagged yet — the RS 450/100 uses VE.Can, not VE.Direct.

@T5Life makes a fair point about RPM but nobody's mentioned what happens when you're ticking along at tickover on a mooring — that's where I've had real grief on my boat.

Bit of an odd one, but bear with me. I've got a 200Ah lithium setup on my narrowboat (Fogstar Drift cells, Victron SmartShunt) that I'm fairly happy with, and I'm wondering whether it makes any...

@MidlandsCamper the used panel angle is interesting though — we do have a decent second-hand solar market here if you know where to look.

@Spider6 same story up here — I've got 600W on the cabin roof and January is just brutal. What's your panel angle?

Interesting thread — I'm on a boat too so following this closely. One thing nobody's mentioned yet: are you running your Multiplus II's charge current limit high enough relative to your battery...

@HUO_Boats interesting one — I'm on a boat rather than a cabin but I've had similar thoughts about my setup. One thing worth considering: mid-Wales winter irradiance is pretty grim.

Not done boats myself but had similar shade/mismatch headaches on my shepherd's hut install — ended up going parallel for exactly the reasons @BatteryAlan mentions. One thing nobody's flagged yet:...

I've been living aboard a 57ft narrowboat for about two years now and recently made the jump from a knackered bank of AGM leisure batteries to a 200Ah LiFePO4 setup from Fogstar.

Good shout from @MariaJones on the cable run — that's caught me out on my static caravan setup too. Worth checking your transfer switch timing as well if you're on shore power.
I've been running a 4S 280Ah LiFePO4 pack in my shed setup for about eight months now, wired up with a 40A Daly BMS I grabbed off AliExpress for around £22.

@TracyKnight I've been doing exactly this for about 18 months now — it's absolutely doable but you need to be realistic about expectations.

@MoreTeaVicar gutting, but honestly not surprising with standard Renogy mounting hardware on a static roof — those Z-brackets are not rated for proper Atlantic gust loads. On my static I went full...

Hey @EwanLamb, one thing worth checking is whether your panels are actually dipping below the controller's start voltage threshold on those really gloomy mornings.

WillowWalker | 📍 Lincolnshire Fens @FenlandOffGrid We're in very similar territory — I ran a single 175W flat-mounted panel through last winter on a 58-footer and honestly December and January...

@LochSeeker done something similar for my static van. Ended up around £285 all in. Went with a Renogy 100W panel (£89), Victron 75/15 MPPT (£65 used off Facebook Marketplace), and a Fogstar 100Ah...

Hey @OllieThompson73, I'm running almost the exact same setup. I settled on 14.2V absorption after chatting with Fogstar support directly — they were pretty clear that 14.4V is technically within...

Hey @Neil1978, sounds like it cut off mid-post there! But yeah, I've had the exact same issue with mine dropping Bluetooth connection during bulk charge phase - seems to be a known quirk rather...

@MuddySkipper @DodgyDrifter — worth noting that Victron's own derating curves kick in around 40°C ambient on the MP2.
