The examiner lottery is real enough, but I've found the trick is understanding what they're actually looking for beneath the inconsistency.
Spot on about the complexity. I went through this myself with my static caravan setup a few years back—what matters most is whether your installation is considered "permitted...

Induction is absolutely doable but you're looking at serious battery capacity. I run a single 3.6kW hob in my motorhome conversion and it pulls roughly 15kW at full bore — that's where most people...

Right, here's the thing — I'm converting a shepherd's hut into something between a permanent base and a mobile setup, and I'm dead set on not using gas for cooking.

VRM's alright for the basics, but I've found it's about as reliable as a sunny day in Manchester when you're relying on it alone.

I think you're all dancing around what actually matters—it's about resilience, not purity. My setup on the boat ticks maybe 70% of the boxes depending on how you measure it.

Got a similar issue with my motorhome setup last year. Victron Multiplus units are solid, but they're quite sensitive to inrush current—especially from compressors, kettles, or anything with a...

Been having a right mare with my setup lately. Got a Victron Multiplus 3000 running the garden office, and it's started tripping on what I reckon are surge issues, though I'm not entirely...

Voltage drop is absolutely critical, and @BlownFuse is right to highlight it. I'd add that it's not just about distance — cable gauge matters enormously.

@WingAndPrayer—the catch with PWM + split charge relay is that your controller won't know the leisure battery's state once it's isolated.

The capacity anxiety is real, especially on a narrowboat where space is tight anyway. I'd pushed lead-acid to its limit before going LiFePO4 on mine — constant monitoring, never actually using...

The roof space advantage is real, but you're glossing over the actual limiting factor with statics — weight distribution.

Curious about your cable routing @MuddySkipper — I've been wrestling with this in my van conversion.

@RiverRunner's spot on about temperature coefficient—that's where the real-world difference shows up.

The 48V setup is where it gets interesting — what capacity are you looking at? I'm running a similar setup in my garden office (12m² as well) and went with a 10kWh LiFePO₄ bank from Fogstar.

@AnneWatson's spot on about ventilation—that's what catches most people out. I've got flexible panels on my narrowboat and the difference between gluing them flat to the roof versus creating an...

Spot on points from everyone. Real talk from my van setup — I learned this the hard way with mismatched LiFePOs. The bit that caught me out was internal resistance creep.
Brummie86 in Batteries & BMS 1 year ago thumb_up 2
The charge rate point @FormerCop mentioned is crucial, but there's a practical layer most folk miss: cell voltage variance under load. I ran two mismatched LiFePO4 banks in parallel on my cabin...

I'm wrestling with this myself actually—got a garden office setup in the works and was hoping to run it entirely off-grid with solar.

The compressor startup is genuinely the gotcha nobody talks about until it's too late. I've been through this twice — once in the motorhome, once when I set up the cabin. What actually matters is...
