@ForestJenny really curious about this — did you find the MPPT was efficient enough doing it that way, or was there noticeable loss compared to a dedicated DC-DC converter?
I've got a similar...
Has anyone tested whether this affects the short circuit protection trigger threshold specifically, or is it more general communication drop-outs with the newer JBD firmware versions?
Asking...
Really impressive build @NickHughes. Quick question — how are you managing the charge controller side of things when all three sources are potentially pushing power simultaneously?
Been catching up on some threads elsewhere about this and it's triggered a memory of something I had with my garden office setup last winter that I never fully resolved.
Running a Victron...
Not a narrowboat owner myself but I've dealt with similar tripping issues on my motorhome when I upgraded my inverter, so hopefully some of this is useful.
First thing I'd check — what size fuse...
Slightly off the thread topic but this actually got me thinking about my garden office build — I went with Victron kit throughout and the scalability is what sold me on it.
@SueThompson what's the actual load profile across those three consumer units? Are they all running simultaneously or is it more staggered usage?
Reason I ask — I've been planning something...
Not strictly marine here but I've gone through the same lithium debate for my motorhome and garden office setup, so maybe some crossover experience is useful.
The weight argument alone would've...
Relevant to me this — got a similar setup in the motorhome with a Ford Transit base and the smart alternator is definitely doing odd things.
Quick question for anyone who's cracked this: does the...
@LutonBuild had exactly this with my garden office build. The SmartSolar 150/35 wants to see a decent margin above battery voltage before it'll wake up and start doing anything useful.
Two options...
Watching this thread closely — doing something very similar in my motorhome build.
One thing worth flagging: the Multiplus II's PowerAssist feature is genuinely useful here, but you need to be...
Been looking into this for the garden office build and keep coming back to the washing machine motor route.
Yeah, this is something that's been bugging me for a while now. Even on months where I've barely touched the grid — running mostly off the solar setup in the garden office — the bill still seems...

Running a similar setup in my garden office and the thing that caught me out was the monitor draw.
@DerekDixon that's a fair point on string design discipline. For my garden office setup I spent ages working out string lengths to stay safely under the MPPT ceiling — gets tricky when you're...
