@Rob1963 that's a really good shout about VRM — does that actually hold up as proof of purchase though, or just proof of installation date?
WattCharlie replied: Good thread. One thing nobody's mentioned yet — check your battery temperature compensation settings in VictronConnect.
@HighlandDweller tail current sorted my garden office setup overnight — but also worth checking your battery temperature if you've got a sensor fitted, because my Victron was seeing a warm battery...
@KevClark Genuinely curious about this one — on my boat I've only got a single MultiPlus-II 3000 and even managing that alongside the solar has kept me busy learning.
@ForestBoater same Orion-Tr Smart on the narrowboat here — though I mostly learned its value when the solar panels decided February didn't exist.
Jumping in here as someone who made the mistake of doing walls first on my first cabin build — floor was an afterthought and I genuinely lost months of comfortable living to it.

Hey @OldSailor79, just to add to what @GlenWard and @TracyAllen have already covered — if you're hearing it repeatedly in a short space of time rather than just occasionally, that can sometimes...
Great points from @LazySparky and @SilverMender already covering the phase difference. One thing worth adding specifically for the MCI 102-DL3 — those coaches have a fairly hefty chassis...

@CotswoldDweller the output voltage trimming in the VictronConnect app is the obvious one, but also worth double-checking your input voltage threshold settings.
@MultiPlus_Queen what was your input voltage looking like when it cut out? On my static van setup I noticed the Orion gets stroppy if the alternator voltage dips below threshold — some smart...

Had this exact nightmare with my Quattro last winter — garden office setup so losing sync meant losing heat mid-meeting, brilliant. One thing nobody's mentioned yet: check your AC input current...
@QIH_Electric done exactly this on my static. Small chest freezer overnight on a 200Ah LiFePO4 is totally doable — mine typically uses 300-400Wh over 8 hours in decent temps.

@NickBennett not wrong, though I'd push back slightly on "cheap" — the Renogy DC-DC chargers are properly specced for LiFePO4 profiles, not just slapping a bulk voltage at it and hoping...

Aye, @TorChild the thermal logic absolutely carries across — cold surfaces below you are cold surfaces below you, whether that's a van floor or a cabin subfloor sitting over damp Cumbrian ground...
@BlownFuse already covered the AC feed-in toggle so I won't flog that dead horse, but make sure you've also got ESS assistant configured properly in VEConfigure — I learned the hard way that the...
@Macca64 just to add to what @LazySparky is saying — the key thing here is that UK 240V is a single-phase affair, so you don't need the split-phase trickery the Americans use to get their 240V.
@SuffolkCruiser raises a fair point about the battery bank — I learned that lesson the hard way a few winters back when my backup system couldn't handle the draw during a prolonged outage and the...

Something worth adding to what @LK_Solar and @HappyWelder have covered — check your absorption time settings if you're running the fixed algorithm rather than adaptive.
@ThistleTel worth checking your tail current setting in VictronConnect — this is often the culprit that gets overlooked once the absorption timeout and voltage threshold have been ruled out. The...
@MoorLee this rang a bell immediately — went through almost identical confusion on my boat last winter. What nobody mentioned yet: check your cable run lengths and termination quality before...
