Anyone else running Victron on a static caravan? Share your setup

Been running a Victron SmartSolar MPPT 100/30 on my static for about 18 months now, paired with two Fogstar 100Ah LiFePO4 batteries. Total of 400W on the roof (two 200W Renogy panels). Genuinely surprised how well it holds up through a grey UK winter — though "surprised" might be generous, I did spec it properly.

Day-to-day I'm pulling maybe 20-30Ah for lighting, a 12V fridge, and phone/laptop charging. The Victron app is dead useful for obsessing over the numbers, which I absolutely do.

Curious whether anyone else has gone full off-grid on a static rather than just supplementing mains. I've got shore power available but honestly barely touch it between April and October. The 200Ah of lithium headroom makes a big difference vs the lead-acid setup I had before — night and day, literally.

What's everyone running for battery capacity and has anyone bothered with a generator for winter backup? Feels like overkill for my use case but I'm on the fence.

@ShedGenius similar setup on my cabin but I went slightly bigger — Victron SmartSolar 100/50 with 600W of panels (three 200W Renogy's) and a single Fogstar Drift 200Ah.

Biggest win for me was wiring it all up through the Victron Cerbo GX so I can monitor everything remotely. Dead handy when you're not on site.

One thing I'd add that you might not have considered — if you're thinking about EV charging off it at any point, make sure your inverter's big enough. I run a Multiplus-II 3000 which handles my motorhome top-up fine but it's probably overkill for a static.

How are yours handling winter? My Fogstar's been rock solid but the shorter days do bite.

Interesting thread this. Running a Victron Multiplus-II 3kVA on my static in Luton — mainly because I wanted proper EV charging capability alongside the usual loads.

Got 800W of panels feeding a SmartSolar 150/45, paired with 3x Fogstar Drift 100Ah in a 24V config. The Multiplus handles grid passthrough when the sun's being rubbish.

The EV bit is where it gets interesting — using the scheduled charging feature in VenusOS to only top up the car when SOC is above 80%. Means I'm rarely pulling from the grid for it.

@ShedGenius your 400W setup would struggle with any EV charging obviously, but for general static use that sounds perfectly sized. @Harry1965 what loads are you running on the 600W? Curious whether you're seeing much grid top-up through winter.

Lovely to see this thread — it mirrors almost exactly the journey I went through with my tiny house build a couple of years back.

Running a Victron SmartSolar 150/35 here with 600W split across two roof pitches (awkward east/west arrangement, but the MPPT handles the mismatch surprisingly well). Paired with three Fogstar Drift 100Ah cells managed through a Cerbo GX — the visibility into what's actually happening is genuinely transformative once you've had it.

One thing nobody mentions: spend the extra on proper MC4 connectors and decent cable runs from the start. My first season I bodged it slightly and lost measurable efficiency. Pulled it all apart last spring, redid everything properly, and the difference showed up immediately on VRM.

@LutonNomad the Multiplus-II is on my wishlist — curious what your grid-tie situation looks like with the static park management.

Really useful thread this — I'm in the planning stages for a shepherd's hut build and trying to nail down the right Victron kit before I start.

Quick questions for those already running this kind of setup:

• Did any of you go 12V or 24V battery bank? I'm leaning 24V for the efficiency gains but worried about appliance compatibility
• @48VWizard — did your tiny house build throw up any surprises with the Victron integration that you'd do differently now?
• How are people handling the monitoring side — just the VRM portal, or is anyone running something alongside it?

I've got two Fogstar Drift 100Ah cells sitting in the garage waiting for a home, so keen to get the system design right before committing to the MPPT size. Don't want to underbuy and regret it six months down the line.
