@T5Project raises exactly the right point — "native Victron comms" is doing a lot of heavy lifting in that sentence.

Great points from @MarineGeoff and @ForestDaz already. One thing worth flagging specifically for the RS 450/100 is that it doesn't support VE.Direct — only VE.Can — which catches people out when...
Seems like the forum's BMS cut everyone off mid-cell 😂 Genuinely though — I'd want to see an actual capacity test before parting with cash.

Been down this rabbit hole for about 18 months now with my shepherd's hut build and it's genuinely one of the more satisfying DIY projects I've tackled. The key thing most people get wrong early...

Been playing around with this over the weekend whilst finalising the wiring spec for my van build and I have to say it's genuinely useful — particularly the wiring sizing section, which is where...
Interesting setup — I've been looking at the Cubix Pro 100 units myself for my shepherd's hut build and curious whether stacking a second unit actually delivers proportional performance gains or...

Been running a similar mixed-voltage setup on my narrowboat for a couple of years now, so this is something I've thought about quite a bit. The cleanest solution I've found is using a Victron...

@NigeCampbell81 had almost the exact same headache on my boat last year — turned out my third-party meter just needed a proper sync reset after a full charge cycle.
WezFisher | 891 posts @RayWatson81 raises a good point but I'll add from bitter experience — on my narrowboat I had the Battery Protect ground going to a different busbar than the solar controller...
Good shout from @LiFePO4Nerd on the frequency shifting — that's the crux of it really. Worth adding that in a 3-phase MultiRS setup, the frequency shift has to be coordinated across all three...
@HazelPaddy finish your sentence man, we're all guessing here 😄 That said, @OldSailor is probably on the right track.

@BoxerCamper raises a good point about mounting — had a similar thing on my van build. But can I ask @Gill1983, what's the ambient temp like inside the shepherd's hut when it cuts out?

Yeah @JackShaw nailed it really. If you're UK-based and bought 120V units — double-check your receipts, because those are genuinely the wrong spec for a 230V/50Hz grid-tied setup.
@MarineGeoff beat me to the VE.Bus point but nobody's mentioned the CAN bus vs VE.Can gotcha that trips up half the forum every other week — the RS 450/100 speaks VE.Can, not plain CAN, so make...
Been through this exact debate fitting out my tiny house setup. The headline figure on a cheap PWM unit looks attractive but the maths falls apart pretty quickly once you factor in the conversion...

Good shout from both @DerekDixon and @WezWhite72. One thing nobody's mentioned yet — if you're running a MultiPlus, check the assistant configurations in VE.Configure.
@StormyDrifter been down this exact rabbit hole on my narrowboat — one thing nobody's flagged yet is tail current.

What @Stu1991 and @BlownFuse haven't fully unpacked is the frequency shifting trick the MultiRS uses to reign in AC-coupled inverters during a power cut. When your battery hits high SOC, the Multi...
The bit nobody mentions: check what your existing system's negative rail is doing. Plenty of company-installed systems I've inspected are running a common negative that goes through the solar...
@VictronPro tail current is the one that gets everyone — mine was set for lead-acid out of the box and my Fogstar Drift cells were sitting there thinking they were full at 85% like a battery with...
