Worth adding — the type of inverter matters a lot here too. Modified sine wave struggles even more with motor loads than pure sine.

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...
Been running my garden office off-grid for about 8 months now and honestly can't believe I didn't do it sooner.

Running almost exactly this spec for my garden office — 400W Renogy panels + 100Ah Fogstar Drift LiFePO4.
@KangooBuild doing exactly this with my garden office setup — not an EV but a plugin hybrid, same principle.
@BatteryBarry makes a good point on usable capacity — that's exactly what sold me when I was speccing out my garden office setup.
One thing I'd add: weight saving is massive if you're building a...
@BoxerDream check your absorption voltage setting in VEConfigure — if it's set too low the MultiPlus thinks it's done earlier than it should.
Finally getting round to sorting proper power for my garden office. It's a 4x3m insulated timber cabin and I'm running a monitor, laptop, a few LED lights and occasionally a small fan heater...
Same thing hit my garden office setup last year — Multiplus in bulk was causing my genny to hunt badly.
Got a garden office running on similar kit — MultiPlus-II with Fogstar cells and a couple of Renogy panels feeding a SmartSolar.
What worked for me was setting the ESS mode to "Keep batteries...
Been looking into this myself for my garden office setup. Got two 12V lithiums running in parallel and was initially worried about keeping them balanced, especially since my solar input's a bit...
Got a Drift 5.12 powering my garden office setup and honestly can't fault it. The thing that gets me is how predictable it is — no random shutdowns mid-work when the sun dips behind clouds.
Got a similar issue in my garden office setup after winter — not quite the same environment as a narrowboat, but moisture is definitely the culprit.
Before you tear everything apart, are you...

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.
