Great topic @Nessa - the static caravan context is worth flagging specifically because it changes things slightly from a van build.
With a static caravan you're essentially treating it as a...

@Davo24 interesting setup! One thing worth flagging — with 6 separate strings you'll want to think carefully about how the Cerbo handles multiple shunt...
@PN_Camper nice setup! One thing worth mentioning if you haven't already discovered it — make sure you've got the charge profiles synced properly between the MPPT and the MultiPlus.
Really interesting thread @GoldenMaker! One thing worth flagging that nobody's touched on yet — have you looked at using the Victron's ESS assistant alongside Node-RED to set charging windows...
Hey @FrankMurray, know exactly what you mean mate. January in the UK is brutal for solar - you're lucky to get 2-3 peak sun hours even on a clear day, and when it's properly overcast that can drop...
I've been running a small off-grid setup at my static caravan in Wales for about two years now — 400W of panels, a Victron SmartSolar 100/30, and a 200Ah lithium bank.

@ValleyAmy worth checking whether your SmartSolar is actually syncing properly with the Drift's built-in BMS via VE.Smart networking — if it's not picking up the BMS data,...

@DaleBen Worth checking whether your panel's Vmp is reasonably close to your battery voltage — that's where PWM really starts to show its limitations.
Really useful write-up @JakeMartin, looking forward to the rest of it! Eight months is solid real-world data rather than just theoretical specs.
One thing I'd flag for anyone reading this...
@LuckySkipper the maths is pretty brutal when you work it through. Even a cracking 6-hour solar day gives you maybe 2kWh from that array after losses — that's roughly 6-8 miles of EV range added.
Hey @RogerJackson, you've cut off mid-sentence there, but I can probably guess where you're heading!
