Running a Shoreline chest freezer on my narrowboat for two years so can give you actual numbers rather than theory.
My 70L unit draws roughly 80-100W when the compressor...
Ran into exactly this on the narrowboat before I sorted the configuration properly. The problem was my inverter charger (Victron Multiplus) was set to draw from the grid at the wrong threshold, so...
Running a 12V fridge full-time on a narrowboat is absolutely doable with 400W, but the honest answer is it depends heavily on your battery bank and how much you're moving.
On my boat I've got 400W...
@DailyBuild good timing on this thread — done almost exactly the same conversion on my 60ft trad stern last year, 280Ah Fogstar Drift paired with a Victron MultiPlus-II 3000.
One thing that bit me...

Did exactly this transition on my narrowboat two years ago — went straight to 48V Victron MultiPlus-II 3000 and haven't regretted it once.
@MarineGeoff...
@WhatsAFuse65 One thing nobody's touched on yet — days of autonomy. For a garden office in the UK, I'd plan for at least 2–3 days of usable storage without meaningful solar input.

@GillGibson worth looking closely at your OCP (overcurrent protection) trip threshold in the JK app — the 200A active balancer unit ships with...
@CallumHamilton83 this is almost certainly the low-temperature charge protection cutting in — JBD's default settings are typically around 5°C charge cutoff, which matches your symptoms exactly.

Running a 200Ah Fogstar Drift LiFePO4 alongside an older 100Ah Battle Born on my narrowboat, each with its own BMS (the Fogstar's internal one plus a Daly 100A on the Battle Born).
@MarineGaz raises the critical point about the BMS interference — worth adding that on the Transit specifically, the negative routing matters enormously for shunt accuracy.
Been mulling over something similar for my narrowboat setup and thought it worth raising here.
Currently running an EasySolar-II GX 24/3000/70 (2022 build) as the heart of the system —...
Been running a pair of Phoenix inverters on my narrowboat for the better part of four years now — a 1600VA for auxiliary loads and a 3000VA for the main system — so this PE-N bridging question's...
The IP rating point @DODQueen raised is spot on, but equally important is what's inside that enclosure.
Two years is spot on for getting a proper feel for the community without making rookie mistakes publicly.
The startup surge is real, but if you've got decent lithium like yours, a properly sized diesel heater won't tank your voltage.
