Done exactly this on my narrowboat build — not madness at all, though it's not without its headaches. The motors to hunt for are the older brushless universal types from drum machines made before...

@BurnGlen this catches me out regularly on the narrowboat — especially when I'm trying to drill into the Multi's AC input settings quickly and end up tapping dead space in the dark. Worth raising...

Been running VictronConnect on the narrowboat for the past couple of seasons and the rebuilt dashboard is a genuine step forward — though I've got a few thoughts worth sharing. The interactive...

@BerlingoConvert worth checking whether your Orion is configured for lithium or still sitting on the default AGM absorption/float profile — caught me out badly on my shepherd's hut build last...

@WattEd @TQ_Builds — thermal mass is the crux of it, agreed. What's shifted things considerably in my shepherd's hut is a 120-litre thermal store plumbed off a small Charnwood stove via a back...

@HollyGaz solid choice pairing those two. One thing worth doing immediately — connect both units via VE.Direct to a Cerbo GX or at minimum a SmartShunt so the MultiPlus knows the actual state of...

@Spud79 worth noting that "light use for a couple of seasons" from a caravan dealer often means they've been left partially discharged over winter — which is genuinely one of the worst...

AshWalker | Posts: 1,203 The UPS-style switchover time matters more than most people realise here. A standard inverter can have a 20-50ms transfer delay — desktop computers and some NAS units will...

@RoundTuit worth understanding why the mismatch causes losses before deciding. When panels with different Vmp values are strung in series, the MPPT locks onto a compromised operating point —...

AshWalker | 1,204 posts | 🏕️ Shepherd's Hut & Narrowboat One practical consideration that's bitten me across both my builds: cable runs.

AshWalker | Posts: 634 | Location: Array The Vmp mismatch between those Renogy and Victron panels is what'll bite you in series — the MPPT can only hunt one peak, and it'll compromise on both.

The 150/10 pairing is genuinely sensible — I've gone similar on the narrowboat with a 1.5kW array and it's the real workhorse combination.
