Anyone else using a Victron Cerbo GX to monitor a static caravan setup? Worth the money?

Just pulled the trigger on a Cerbo GX for my static and I'm still not 100% sure I've done the right thing. It's connected to a Multiplus 2 (3000VA) and a SmartSolar MPPT 150/35, pulling data from four 200Ah Fogstar Drift LiFePO4 batteries. The VRM portal is genuinely impressive once you get it talking properly — real-time SOC, consumption graphs, the lot.

My main issue is the Touch 50 display. At £150-odd it feels steep for what is essentially a glorified screen that just mirrors VRM. I've got it mounted inside the van but honestly I check the phone app more than anything else. Anyone ditch the physical display and just run headless with VRM?

Also curious whether the Cerbo is overkill for a shepherd's hut build I'm planning — probably only a 400W panel setup with a single 200Ah battery. Would a cheaper BMV-712 and SmartSolar with Bluetooth do the same job for that scale, or is there something I'd genuinely miss without the Cerbo's full integration?

@Smudge78 worth every penny in my experience. I've got a Cerbo GX running on my static with a Multiplus 2 (5000VA) and a pair of SmartSolars — the VRM portal is genuinely brilliant once you've got it set up properly. Being able to check SOC, solar yield and inverter load remotely from my phone has saved me several trips out when I thought something was off (usually wasn't).

The Touch 50 display is worth adding if you're on-site regularly too — just mount it somewhere visible and you've got everything at a glance.

Main tip: make sure you've got a decent 4G router or ethernet out there for VRM to work properly. I wasted about two weeks thinking mine was faulty when it was just poor signal dropping the connection.

@Smudge78 I ran a Cerbo GX in my motorhome for two years before I really understood half of what it was telling me — and that's the honest truth. The learning curve is real, but once it clicked, I wouldn't go back.

The thing that convinced me it was worth it was the historical data. Had a dodgy cell in my Fogstar Drift battery pack last winter — the Cerbo's graphs showed exactly where the voltage was dipping under load before I'd even noticed anything was wrong. Caught it early, sorted it before it caused proper damage.

One tip: get the GX Touch 50 screen mounted somewhere you can glance at it daily. The VRM portal is brilliant but there's something about having live data in front of you that changes how you manage your system.

@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. The VRM portal is the real game-changer for me; being able to check my motorhome's solar stats from anywhere on my phone is brilliant.

One tip — get the Touch 50 screen if you haven't already. Makes poking around the menus so much easier when you're actually on-site rather than squinting at a laptop.

Your Multiplus 2 + SmartSolar combo will talk to it beautifully over VE.Can/VE.Direct. You'll wonder how you managed without it within a month, trust me! 🙂

@Smudge78 ran a Cerbo GX in my motorhome for three years before moving it into a static backup setup — best decision I made, keeping it rather than selling it on.

The bit nobody tells you upfront: the VRM portal historical data is where the real value lives. Not the live dashboard — that's just for fiddling. Give it six weeks of logging and you'll see exactly where your system is bleeding watts overnight, which loads are killing your battery before dawn, all of it laid out plainly.

Static setups especially benefit because the patterns are so repeatable. Mine flagged a failing fridge compressor cycling oddly before the fridge itself gave any obvious signs.

Worth the money? For emergency backup monitoring alone, yes — you'll catch problems before they strand you without power in January. And in the UK, that matters.

Great setup @Smudge78 — Multiplus 2 paired with the 150/35 is a solid combination. One thing I'd add that hasn't been mentioned yet: make sure you've got your VRM portal properly configured and alerts set up. The email/push notifications when your battery state of charge drops below a threshold are genuinely useful, especially if you're not on site full time. Saved me a trip out to my static twice last winter when something wasn't quite right with charging. Also worth investing a bit of time in the Node-RED integration if you're feeling adventurous — you can automate some surprisingly useful stuff without needing to touch the wiring. The learning curve is real but stick with it.

Got a Cerbo GX running my garden office setup — Multiplus 2 + 150/100 MPPT, Fogstar Drift lithium bank. The VRM portal is where it earns its money for me. Being able to check state of charge from inside the house without trudging out in the rain is genuinely useful.

One thing worth knowing @Smudge78 — make sure you've got the tank level and temperature inputs configured properly if you're using them. Easy to overlook during setup and then wonder why your dashboard looks half empty.

Also the Node-RED integration if you want any automation later is a nice bonus. Bit of a learning curve but solid once it's running.

@Smudge78 one thing worth flagging that nobody's touched on yet — the Cerbo's two-way grid metering via a Carlo Gavazzi ET112 (or the Eastron SDM630 if you want per-phase detail) transforms the whole system. Once you've got that wired in, ESS mode on your Multiplus 2 becomes genuinely intelligent; it'll decide in real-time whether to pull from grid, battery, or solar based on your configured thresholds. For a static where you're potentially paying standing charges year-round, optimising that interaction properly can meaningfully offset the Cerbo's cost over a season or two.

Great thread! @Smudge78 to answer your original question — absolutely worth it for a static setup. One thing nobody's mentioned yet is the Node-RED integration built into the Cerbo. It lets you create custom automations without needing any external hardware — things like automatically adjusting your MPPT charge limits based on battery temperature, or triggering alerts when your system behaves unexpectedly. It's buried in the menus but genuinely powerful once you get into it. Takes a bit of learning but there's decent documentation on the Victron community forum. For a permanent installation like a static, you'll get far more value from it than someone running a portable setup.

@Cerbo_Geek that Carlo Gavazzi ET112 integration is genuinely underrated — I've got one clamped on the incoming supply at my static and the ESS assistant uses it to achieve near-perfect zero feed-in. What really sold me though was being able to monitor the EV charging load separately via a second CT clamp input. When I'm running the motorhome's onboard charger off the Multiplus overnight, I can see exactly how much that's pulling versus base load. The VRM historical data has already helped me resize my consumption assumptions significantly. Still tweaking the ESS charge/discharge thresholds but the visibility alone justifies the cost.
