I've had my Cerbo GX running for about six months now and overall it's brilliant, but I'm hitting a frustrating wall with monitoring my Jakery Explorer 1000 Plus that sits alongside my main 200Ah...

Hey @SteveBurns, I had something similar with my 100/20 last spring. Worth checking whether your phone's battery optimisation settings are killing the Bluetooth connection in the background -...

VM_Solar | 847 posts @TracyRobinson The EF2000iS is a solid choice for exactly this role - that inverter output means you can safely run sensitive electronics without worrying about voltage...

Just finishing up a van build with four 70Ah Eve cells wired in series for a 12V 280Ah bank. Running a JK BMS (the 200A active balancer version) and overall I'm dead chuffed with it — balance...

@JohnBaker worth mentioning something nobody's touched on yet — if either BMS trips under load, the surviving bank suddenly has to carry the full current demand on its own.

Great thread. One thing I'd add that hasn't come up yet – check your engine earth straps. On high-mileage Transits these corrode badly and cause all sorts of gremlins with sensitive electronics...

Really interested in this thread — I've been piecing together something similar for my narrowboat over the past year.

We're about three weeks into the new year and I'm genuinely starting to question my whole setup. I've got two 200W panels on the roof facing south-ish (maybe 15° off due to the van layout) and a...

@Brummie88 One thing nobody's mentioned yet — AGM self-discharge is surprisingly significant if that battery sits unused for weeks between outages.

@LuckySkipper I run a similarly-sized setup in my shepherd's hut for emergency backup, and the penny dropped for me when I realised I was essentially asking a garden hose to fill a swimming...

@VanKev interesting timing on this thread — I've been thinking about the same thing but for a narrowboat rather than a van.

BreezyCaptain | Posts: 156 @OakTel Worth double-checking your low voltage protection settings in the JK app – there's a "Cell Undervoltage Protection" value and a separate "Cell...

Running almost identical kit in my shepherd's hut actually — picked up a second-hand MultiPlus-II 5000VA for £480 last year and it's been faultless.

@DorsetCruiser those winter figures would be useful to see — I've been wrestling with the same question at the shepherd's hut. My van conversion taught me that EV charging is a completely...

YorkshireCamper | 234 posts Slightly different use case here (static caravan rather than garden office) but the principle's the same.

OffGridPete | Posts: 2,156 Running a similar hybrid on the narrowboat — LiFePO4 paired with an older 110Ah AGM.

BirchRunner | 847 posts @SimonPalmer worth checking whether the reporting is the issue rather than actual output.
Birch Runner in Q&A 6 months ago thumb_up 8
@MickDavies good stuff. One thing nobody's mentioned yet — cable sizing. Swapping from AGM to LiFePO4 means your BMS can deliver current fast when it wants to.

RayCross | 156 posts To build on what @CamperClive touched on — the Victron ecosystem is worth considering beyond just the controller itself.
