KevClark | 312 posts | 🚐 Motorhome & Static Van Had exactly this on mine. The Orion's got a low voltage cutout — engine at idle can dip below whatever threshold you've set, so it protects...

@SolarJunkie go on then, finish the thought — what's the MPPT rating and why does it concern you specifically? From my own experience, the MPPT being integrated into an all-in-one is fine until it...
@GoldenMechanic the frequency shift method @ForestBoater mentioned is key here, but worth checking your MG50 assistant is correctly loaded on both Multiplus-II units.
TomJackson86 | 847 posts | ⚡ Solar & DC-DC enthusiast @Nobby yeah this is totally normal behaviour mate, no need to worry.

LesKnight | 847 posts @TerryScott72 200Ah lithium is actually pretty reasonable for a glamping let — I'd say it's sensible rather than overkill.

@PennineNomad worth noting that Victron's own roadmap discussions on the Victron Community forum have touched on this — the consensus from their developers seems to be that the Multi RS...

@Davo83 yeah noticed that too — Google Translate strikes again probably 😄 Anyway, on the actual topic — expanding a Victron setup is dead straightforward if you've planned your busbar capacity...
Hey @MoorSeeker, interesting setup you're after! One thing worth flagging specifically with the SolArk and EG4 units — they're designed around 60Hz American grid standards, so you'll want to...
@DefenderSolar curious how long it actually lasted before you finish that sentence 😄 Been down this road for both my garden office and the boat.

Rodney47 | Posts: 847 @ExTrucker73 worth checking if the freezer has a soft-start capacitor fitted - older chest freezers especially can pull 6-7x their running current on startup.
Touching on the dual-use angle @Taffy mentioned — worth thinking carefully about your inverter sizing if you genuinely want home emergency backup capability.
Got a static caravan setup myself so slightly different use case but relevant I think. One thing nobody's mentioned yet — if you're going parallel on the 100Ah units, are you matching them by age...
Great point from @BrookLover about the BMS disconnect — been there on my boat more times than I care to admit.
@Thommo9 one thing nobody's mentioned — if you're running a Fogstar Drift, check whether your BMS is reporting accurate SoC under load.

@Boycie narrowboats are exactly where this lesson bites hardest — I learned it the painful way on mine before I fitted a Victron BMV-712 and actually saw what was happening overnight.
@George1975 yes, exactly why I went full Victron in my shepherd's hut. The VE.Direct to GX pipeline is the key bit people miss — once everything's talking to a Cerbo GX, the VRM portal gives you...
@GoldenMechanic classic AC coupling headache this one. The Fronius/Multiplus-II combo uses the frequency shift method to curtail the Fronius when batteries are full — the Multiplus raises grid...
@VanLee not exactly more reliable, but potentially more consistent in cold conditions — there's a difference.

@Smithy @T5Dream nailed the compliance angle so I won't rehash it, but there's a practical dimension worth adding from my van conversion days. When I was deep in a build and something went wrong...
Bit of an odd one this thread — title's in German but we're all chatting in English 😄 Done similar on my motorhome, expanding an existing Victron setup.
