Been using the SolarSense 750 for the past few weeks to scout panel positions on the boat and the garden office — genuinely useful bit of kit for figuring out shading issues across different times...
Bit of a niche one this but curious if anyone else has run into similar grief.
Running a Global Link 520 alongside a Blue Smart IP22 12/30 on the boat, and I keep getting weird behaviour when...
Same here — both my boat and garden office installs showing flat zeros on the forecast.
Worth noting that if you're relying on the VRM forecast to drive any automation logic (ESS schedules,...
@Bazza60 looks like your post got cut off mid-sentence but I'll take a guess at what you're hitting —
The Multiplus-II has a low battery voltage threshold that prevents grid passthrough/assist...
@DougPearce been down exactly this rabbit hole on my narrowboat. Ended up ditching ultrasonic entirely and going with a simple capacitive strip sensor on the outside of the GRP tank wall — no...
@PartnerConvert I've run a compressor fridge off solar on my boat for three years so can give you real numbers.
A 45L compressor fridge in decent UK temps will average 20–30Ah per day — duty cycle...

Running the same JK 200A active balancer on my boat bank (EVE 280Ah cells, also from Docan as it happens).
@Spider is right about the current rating being fictional marketing. But there's another angle worth adding — PWM in winter isn't just about the controller being rubbish, it's fundamentally the...

@NickMason had almost identical with my boat bank — JK 200A, EVE 280Ah cells. Turned out to be the balance wires.
@YorkshireExplorer classic DNO quote situation — they see "rural Yorkshire" and just start adding zeros.
Right, before anyone can sensibly size anything you need to answer a few...
Good timing on replacing the lot rather than mixing — hotspot panels drag everything down anyway.
On the boat angle specifically: I'd lean parallel for lower voltage if you're running any DC loads...

@Tom1979 pretty much nailed it, but to be more specific — the concern isn't just moisture, it's shade from rigging. One shaded cell in a series string tanks the whole string.
@ExBrickie same boat situation here (literally). Cerbo GX was the piece that tied everything together for me.
What I'd add — don't overlook the historical data side of VRM.
@WillWebb the dealer being unresponsive is the real red flag here. Under UK consumer law the contract is with the retailer, not Victron — so the dealer can't just pass you off to the manufacturer...
@BorderVanLifer the PWM-in-disguise thing is genuinely rampant. I've bench-tested a few of these and the "MPPT" label is basically just marketing on a £4 chip.
To answer @LindaClark90's...
