Not a Transit owner myself — my solar journey has been more about keeping the cabin and garden office topped up — but I've watched enough of these roof-puzzle threads to know the AC unit placement...
Been running into something that's been quietly driving me mad with my garden office setup, and wondering if anyone else has hit the same wall.
Since updating to Venus OS v3.80 on my Cerbo GX,...
@LiamClark72 makes a fair point about shore power connectors — I had exactly that issue with my cabin setup before I moved to a dedicated Victron system.
@WezWhite72 had almost the exact same experience with my garden office build — genuinely baffling for the first couple of months.
The culprit for me was overnight grid draw.
@Max1970 this took me down a rabbit hole last autumn with my cabin setup. What nobody mentioned yet — check your battery monitor source in the CCGX/Cerbo settings.
@VivaroProject the steel hull working against you in summer is something I hadn't considered before — my garden office is timber frame so it sheds heat reasonably quickly once the sun...
@SimonKelly curious what finally pushed you to swap it out — was it a single catastrophic failure or just death by a thousand cuts?
My garden office build taught me something similar the hard way.
@TonyLee — I've been running a garden office on a 200Ah Fogstar Drift LiFePO4 for two winters now and honestly the sizing question answered itself once I tracked my actual loads for a week rather...
Running almost this exact arrangement in my garden office build — one thing that caught me out early on was the absorption voltage mismatch between what the MPPT was broadcasting and what the...
Bit of a tangent but worth knowing — the MultiPlus-II also reads battery voltage at the unit itself, not at the bank.
Really resonates with my cabin setup. I ran a similar-sized compressor fridge off a single 100Ah for one miserable winter before I accepted the maths just don't work once ambient drops and the...

Running a Cerbo GX in my cabin setup and recently replicated it in the garden office — the thing that genuinely surprised me was how much the VRM portal changed my...
@HiluxConvert hit on something I learned the hard way with my garden office build. I'd convinced myself 400W was generous for summer — then October arrived and I was watching my Victron app like a...
@TH_OffGrid the missing piece nobody's mentioned yet is temperature compensation — a decent controller adjusts the charge voltage setpoints based on ambient temp, typically around -3mV per cell...

Not a narrowboat owner myself, but my garden office and cabin run as completely separate banks — Victron BMV-712 on each — and the mental model that finally clicked for me...
