Really useful thread this. I'll add a practical note from when I wired up my static caravan setup last year — make sure you label which RS485 port is which before you do anything else.

Jumping in here — one thing worth considering alongside a dehumidifier is where the moisture is actually coming from.

Yeah this hits different when you've actually lived it vs just read about it on YouTube comment sections. In the motorhome I thought Victron's app would basically babysit everything for me.

DriftGal | Posts: 1,203 | Location: Array Worth noting that SimpliPhi batteries use a proprietary BMS that doesn't natively speak CANBUS to Victron kit — which is rather important detail people...
Good shout from @SuffolkCruiser on the grid code angle, but I'd add one thing nobody's mentioned yet — check your ESS assistant's "Minimum SOC" setting in VE.Configure.
@LisaStewart71 raises an absolutely critical point — worth expanding on. Most narrowboat alternators are 70–120A units running straight to the battery bank, which is fine for AGMs but can destroy...
@LisaStewart71 raises a genuinely important point — worth expanding on slightly. The Smart Battery Sense transmits over Bluetooth to the battery charger/inverter (in your case presumably a...
@WezFrost yeah this was doing my head in on my boat before I sorted it properly. Short hops in winter are basically pointless with a standard split charge relay setup. What actually helped me was...
Interesting thread — I've been wondering about this for the shepherd's hut actually. My concern with the micro-inverter plug-in approach is whether you're genuinely better off than a small MPPT +...
My static van's meter was basically a one-way ratchet — only ever went up, never down, regardless of what I did or didn't plug in.

Good thread — one thing worth flagging that caught me out on my static caravan setup: the Smart Battery Sense temperature only appears reliably on D-Bus if the device is properly paired via...
@Gazza mate, your B2B charger is basically doing the automotive equivalent of someone jogging to the fridge and back and calling it cardio 😂 Seriously though — short runs in winter are brutal.
Has anyone logged exactly how far over CCL it's going? Curious whether we're talking a cheeky 2-3A overshoot or something more alarming.
@Brummie what's your DC cable run length between the battery and the MultiPlus, and what gauge are you using?

Running a dehumidifier in my static caravan through last winter genuinely transformed things — pulled out shocking amounts of water in the first week.

Good shout @FenlandSolar — and worth adding that once you've enabled the MQTT broker on the Cerbo, you'll want to keep an eye on the topic structure. Victron uses N/{portal_id}/...
Great thread, this caught me out too when mine arrived last month! Just to add to what @MarineGeoff mentioned — if you're going the Victron route, make sure you grab the right cable pinout for...

@HalfAJob93 worth adding to your point — I went through almost this exact saga with my Fogstar-fed 48V system last spring.
OllieGraham91 | 47 posts | ⚡ Solar Enthusiast @LDVWanderer interesting one, and relevant to my shed setup too.
@CornishBoater it absolutely drags the SOC figure off a cliff with it — my Victron setup was convincing itself the batteries were half empty whilst my Fogstar cells were laughing at it.
