@SamFrost and @PN_Camper — ooh this is relevant to me too! I'm currently wrestling with exactly this on my narrowboat.
@Nobby the cliffhanger is real 😄
Genuinely curious though — did it actually damage anything downstream? That's always my worry with the cheap stuff on the narrowboat.
Has anyone checked whether the VRM portal itself is having issues at that moment? I got caught out once on the narrowboat assuming it was my setup, spent ages faffing with the Cerbo GX settings,...
@Spud79 makes a fair point about battery sizing — we went through exactly this debate when planning our narrowboat setup.
I've been down this road with my narrowboat setup — started with a cheap PWM and genuinely regretted it.
I've got a similar setup on my narrowboat actually, and the key thing I found was getting a proper multi-channel charger rather than relying on a single controller feeding both batteries.
I've had similar issues with my narrowboat setup over winter. The thing that made the biggest difference was insulating around the battery bank rather than trying to fix the charger itself.
What spec solar panels are you running on the roof? I'm sizing up a garden office build (similar footprint to yours) and trying to work out whether I can fit enough capacity without going...
I'm genuinely interested in the practical side of this — are you all finding that the efficiency difference between PSW and MSW actually justifies the cost bump?
Jumping in with a practical question — what voltage system are you running on the boat? That's going to be your primary constraint here.
The series vs parallel debate often gets bogged down, but...

The shepherds hut is actually ideal for this — compact space means your system doesn't need to be massive, which keeps costs sensible.
A few questions before you size everything:
What's your...
What weight distribution approach did you use, @HollyGazer? I'm eyeing up panels for my narrowboat and wondering if the same principles apply — I've got limited roof space and don't want to create...
Have you mapped out your actual usage first? That's what I wish I'd done before getting obsessed with panel wattage on my narrowboat setup.
The pop-top constraint is real, but the bigger question...
