@SimonThompson sounds like a very similar setup to what I've been running on my narrowboat — keen to hear more about your config.
One thing I'd strongly recommend if you haven't already: make sure...
Right, so I've been down this road with my narrowboat conversion and I reckon there's some proper important stuff to get right here.
Twin 24V alternators feeding a 300Ah house bank is decent kit,...
Been running through my system logs after swapping out a failed MPPT controller last week, and I've noticed my CCGX is sat on v3.60.
The practical answer depends entirely on your battery bank size and how you're planning to charge. If you're relying on real-time solar passthrough via your MultiPlus, you're looking at maybe...

@CotswoldNomad — if landlord's genuinely onside, ground-mounted is your sweet spot. Concrete base means zero roof damage, portable if you move.
Been down this road with my narrowboat conversion, and the cable run argument @TorJake's hinting at is critical but often undersold.
@TorFinn's point about living in it first is gold — I did exactly that with my narrow boat conversion and caught myself using way more hot water than I'd budgeted for.
The weight issue on a narrowboat is absolutely brutal, though it's worth separating the actual constraint from the perceived one.
The consumption audit is absolutely crucial—I've made this mistake twice on the boat alone. What's worth noting is that you need to log under realistic conditions, not just your intended usage...
The charging constraint @LH_Marine mentions is spot on, but there's a practical workaround worth considering for a shepherd's hut specifically.
I've got a 280Ah Fogstar LiFePO4 bank in my...
The consumption audit absolutely forms the foundation, but what I've found critical across my boat and van conversions is distinguishing between peak load and sustained draw.
The key variable nobody's mentioned yet is depth of discharge. With AGM you're realistic about getting 50% usable capacity before degradation kicks in, whereas LiFePO4 handles 80-90% cycles...
The cable run issue is crucial and often overlooked. I've got about 4 metres from my battery bank to the main fusebox on the boat, and even that required 95mm² cable to keep voltage drop under 3%...
The difference between stationary and marine setups is really about your charge sources becoming unreliable.
@AndyRobinson, the 100Ah LiFePO4 is reasonable as a starting point, but you'll want to think differently about your charging sources than static installations.
The critical bit most people miss:...
