@AnneWatson beat me to the unswitched bit but worth adding — the Multi RS AC out 2 is really just meant for non-critical loads, not for feeding power back into the system via a grid-tie inverter.
@VivaroNomad had exactly this dilemma when setting up my static caravan. Ended up going Fogstar Drift after bottling it on three different eBay listings 😅
The price difference felt painful at the...
@TQ_Builds tag your post and edit it to add the rest of the details — we can't really help without knowing what the actual problem is 😅
That said, I've got a similar-ish setup in my shepherd's hut...
Done exactly this with my shepherd's hut build 😬
Spent ages spec-ing out the Multi RS Solar then nearly bought a job lot of panels without checking the Voc properly.
Had this in my shepherd's hut last February — brutal wake-up call. Ended up wrapping the battery box with some cheap closed-cell foam insulation and it made a surprising difference.
Had a rough few weeks in the shepherd's hut — three days of solid cloud and the 200Ah Fogstar lithium was properly struggling.
Had this exact scenario in my shepherd's hut setup – alternator on the tow vehicle was throwing out some nasty voltage spikes on a long run.
@GlenDixon worth it every time in my experience. Running a Fogstar 100Ah in my shepherd's hut and the usable capacity difference alone sold it for me — you're genuinely getting 80-90Ah versus...
Been running a 400W array (2x 200W Renogy mono panels) on my hut since spring and it's been brilliant.
Not done boats myself but had similar shade/mismatch headaches on my shepherd's hut install — ended up going parallel for exactly the reasons @BatteryAlan mentions.

Had the exact same grief with my shepherd's hut setup. Mini-splits are brutal on startup — that inrush can spike to 3-4x running current even with an inverter-rated unit.
Few things worth...
@BatteryPaula that relay trick is decent but adds another failure point tbh. What I did on my static caravan setup was just wire the SmartShunt's relay output in parallel — it holds state properly...
@JennyThomas57 worth checking the fuel cap vent before you go any further. Had this exact symptom on my shepherd's hut setup — genny would run 20 mins then die, cool down, start fine again.
Had this exact issue on my shepherd's hut setup last spring. Turned out my battery voltage sense wires had a dodgy connection — the MPPT was seeing slightly inflated voltage at the controller...
That's a decent spec for a van. How's the lithium been for you in practice — any issues with the BMS or charging cycles?
What's the actual asking price?
