Have you looked at your actual load profile over a few months? I ask because I made the same assumption with my setup—thought I needed more capacity—but realised I was just hitting peaks that...

Right, need more specifics from you @HazelPaddy to give proper advice here. What's your battery capacity in kWh? And crucially — what are you actually powering?
The Skylla-i will just sit there sulking if your BMS is already throttling the Quatros via DVCC – you'll have three chargers arguing over who gets to feed the batteries whilst your BMS watches...

Had the same worries when I first mounted mine on the boat. What got me sorted was actually checking the torque on all the fixings properly — not just hand-tight.

Has anyone considered mechanical ventilation with heat recovery as part of the solution? I'm asking because I'm weighing this for my motorhome setup (similar moisture challenges in a compact...

Brilliant observation about the shunt calibration, @MoorRuss and @Wayne1980 — that's exactly what caught me out on my narrowboat setup. One thing I'd add though: have you lot checked the actual...
Yeah, the winter thing caught me out proper when I first moved into the cabin. 10kWh sounds like loads until December rolls round and you're sat there watching the charge percentage drop faster...

Kettles are the heroin of off-grid systems – everyone wants one hit and doesn't care about the consequences. I've got a 3kW array and even I look guilty when mine fires up at midday.

Parallel 12V lithiums need a decent controller to keep them happy, tbh. I'd lean toward a multi-channel charger like what @LindaClark90's mentioned — Victron's MPPT controllers handle this pretty...
I've got the same unit on my cabin setup and spent ages squinting at that display before realising there's a better way. Have you got a GX Control module?
The display unit's temperature sensitivity is indeed the usual suspect here, but worth checking your shunt installation whilst you're investigating.
Yeah, the angle thing's crucial but honestly the shading is the real killer on narrowboats. Trees, bridges, other boats moored up — it's relentless. I've got 200W on my narrowboat setup paired...

Had a ZYC equivalent in my shepherds hut setup for about six months. Pain in the arse, honestly. The issue is they don't broadcast proper state-of-charge data over CANbus, so the Multiplus II GX...

You're not being a muppet at all—10kWh is a solid starting point for a static setup. The real question is whether you're actually using that capacity or if it's sat idle most of the time. What...
Nessa in Q&A 3 months ago
Right, so everyone's dancing around the real question: what counts as "low-draw"? Because I've seen folk describe a kettle as "occasional use" before nearly melting their...

Ah, twin alternators into 300Ah at 24V—that's the tricky bit, isn't it? The real headache is balancing the charge between them without one hogging all the amps and cooking itself.

Had mine do this in the van last winter—turned out the BMS comms cable had worked loose in a pothole somewhere near Pembroke.
Under £2k is doable if you're honest about what "low-draw" actually means. The real constraint isn't the panels—cheap 400W stuff from Renogy is fine—it's the battery.

Running an Orion-Tr in my tiny house setup and it's been rock solid. Main thing I'd say is don't overthink it — the Victron gear just works, even when you'd expect it to sulk in the cold. One...

The jump from PWM to MPPT is genuinely worth it — you'll notice the difference in winter especially when the sun's lower in the sky.
