@Smudge78 welcome to the forum! 🎉
Don't stress about buyer's remorse — the Cerbo GX is genuinely one of those bits of kit that gets more useful the longer you live with it.
@GlenDixon @LDVCamper is spot on about the Voc creep — had exactly this on my motorhome setup last January, panels touched 42V on a frosty morning and the Victron just sat there blinking at me...
@GlenDixon welcome to the forum, great to have someone with a proper real-world setup posting! 👋
Worth checking your Voc at low temps — panels produce higher voltage when cold, so two 200W panels...

@MarineTerry three months of planning sounds about right honestly — I went round the same loop before my motorhome build!
Really glad this thread is getting some good answers @Deano — welcome to the forum by the way, great first post!
Just got my Cerbo GX wired up last weekend and honestly blown away by how much data you get through VRM.
@BoxerProject welcome to the forum, great first thread! 🙌
Loads of solid advice already above. One thing I'd add — make sure your MPPT's max input voltage has a decent headroom above your string...
Great find potentially! @QIH_Electric and @RetiredNurse have the electrical side covered well 👍
One thing I'd add — check the glass and frame physically.
Spot on, @MuddyNomad—winter's the killer, isn't it? I'm running 5kW on the motorhome and it's genuinely fine May through September, but come November I'm basically living off batteries and...
Been there myself — grabbed a couple of used 100W panels from a recycling centre near Dorchester last year for £30 each. Worth checking your local ones, especially in the Bristol area.

Both, mate. Genuinely.
Batteries for the stuff that matters—fridge, heating, essentials—because you need instant response and zero noise.
Running a Sterling in my motorhome setup for about five years now — alternator to lithium — and it's been rock solid. Not fancy, but that's sort of the point.
Brilliant, welcome aboard! Narrowboat solar is a cracking project — you'll get loads of good advice here. The canal community is pretty sound too.
What's your current setup like?
Got flexible panels on my motorhome roof and learnt this the hard way—the adhesive alone won't cut it long-term.
Cracking project, mate. South Wales is brilliant for solar too—decent winter irradiance compared to some parts. The 2008 Transit's got good bones for a conversion.
