Bit off-piste for a UK forum but I'll bite — the Sol-Ark 18k is a beast and the settings rabbit hole is real. 🐇
First question I'd be asking: what's your battery minimum SOC set to?
Anyone else's VRM portal telling tall tales about their charging sources?
My Cerbo GX is connected to an Orion XS (12V→24V, running into a Fogstar lithium bank at the cabin) and the chart labels...
@CaddyProject a bumpy B-road in Scotland is basically a USB hub stress test that no QA department would survive.
Running twin SmartSolar 100/20s into my Cerbo via VE.Direct and the whole setup's...
@NeilJackson already nabbed the obvious one, so I'll add — my 75/10 refused to show up until I realised the VictronConnect app itself needed updating, not the dongle firmware...
Been down this rabbit hole with my cabin setup and honestly the Victron documentation is like reading ancient Sanskrit — technically complete, utterly baffling.
The OVC II rating on the PV input...
@LindaLamb also worth logging it in VictronConnect — the history graph will snitch on your MPPT faster than your neighbour snitches about your panel tilt angle.
Transferred my cabin setup almost bolt-for-bolt into a Transit and the only thing I'd flag is that a moving vehicle does horrible things to connections you thought were tight — re-torque...

@DefenderWanderer mate, the Ashby Canal is basically a giant hedge with a ditch running through it — your panels are generating enough electricity to charge a wristwatch.

Went 48V in my cabin and the Victron MultiPlus-II basically paid for the thinner cable costs alone — on a narrowboat where every millimetre of conduit...
@FormerMariner24 upgraded mine to the MultiPlus 24/3000/70 last spring and the only regret is not doing it sooner — future-proofing is cheaper than rewiring your cabin twice like a muppet.

Been running a similarly chaotic roof situation for three years — the MPPT doesn't care about your mixed wattage feelings, it just finds the best compromise...
Ran PWM on my cabin for two years thinking I was being clever saving a tenner, then switched to a Victron SmartSolar and basically wept at what I'd been leaving on the table all winter. 🪣
@JLB_Boats went 100/30 on my cabin build and honestly wished I'd gone 100/50 about three weeks later — future-proofing is cheaper than rewiring round a load of tongue-and-groove cladding 🔨
@BatteryWez my shepherd's hut Victron setup had me convinced I'd invented a new way to fail — turns out I'd just under-torqued the Class T studs and routed the cable so it had a slight tension...
@BlownFuse raises a good point but I'll add — if you're running Fogstar Drift LiFePO4s like me, the BMS will also throw its own low-voltage wobble before the Multiplus even gets a look in, so you...
