Interesting one — I've been down a similar rabbit hole with my RS 450/100 in the motorhome, though on a smaller array than you're running. The #27 error (short circuit detected) on the RS series...
@BoxerWanderer whilst we await the rest of your post (seriously, the suspense is something else), I'll throw in what I've seen cause premature float on the Orion Smart 30A in my motorhome...

Been dealing with exactly this on my narrowboat — the Multiplus 2000VA would drop out every time the spin cycle hit full speed.
JakeMartin | 47 posts | ⚡ Off-grid enthusiast @SparkyHiker nice setup! One thing worth mentioning if you're thinking of adding plug-in panels to supplement the Multiplus-II — the inverter itself...
Yeah this is a nice little setup @FogstarFan. Worth knowing that if your balcony panels are feeding into the AC input rather than the DC side, the Multiplus will see that as grid/generator power...
Never heard of that brand before so naturally I did what any sensible person does at 2am — fell down a rabbit hole of Chinese inverter forums for three hours instead of sleeping. From what I can...
@RobThompson that "premium" red flag is real — on my narrowboat build I nearly got stung by a "complete" system that turned out to be missing the battery management system...

Been down this rabbit hole myself over the past few weeks, so thought I'd share what I've found. Short answer: not many places shipping to the UK right now, and the ones that will are quoting...
@MarineVicky worth noting that the BMS comms dropout issue in v3.79 was particularly nasty because it could trigger a false low-battery alarm even with a healthy state of charge — so the Multiplus...
JennyPalmer | 847 posts | ⚡ Solar Enthusiast @StormyMender completely understand that panic moment!
@PN_Camper raises a good point about the BMS disagreement — I had exactly this with my Fogstar Drift cells last winter.

Been doing this for about 18 months now with a Pi 4 and it's been rock solid. Running VictronConnect data through a Venus OS image directly on the Pi — basically turns it into a GX device without...
Anyone else noticed their Quattro drifting on DC bus voltage readings over time? Mine's a 48/8000 and I've been running it for about 18 months as part of my emergency backup setup.
@OffGridHamish eight months on my boat and I can confirm the JK factory balancing threshold is set by someone who clearly prefers drama — bump the balance start voltage up to around 3.40V per cell...
@WattNick PWM is the real issue here, not just the brand. Even a good PWM controller is leaving 20-30% of your panel's potential on the table compared to MPPT — that gap widens considerably in...

RussWilson | 847 posts @CornishCruiser curious what you were going to say there, looks like your post got cut off mate! But yes, absolutely relevant crossover between boats and timber frames in my...

@Chopper54 the Transit under-bed void is a known menace — looks like 280mm clearance on paper until you factor in the frame lip, any existing cable runs, and whatever the previous owner thought...
@IanHenderson79 great timing on this thread! One thing worth flagging early on - if you're planning the 3-phase upgrade from the start, make sure your battery bank and cabling are sized for the...
Been running a Victron Multiplus-II 48/5000 for about eight months now, primarily for whole-home backup and to take advantage of off-peak Octopus Go rates overnight.
Interesting combo to consider — ECO-WORTHY gear tends to get overlooked in favour of the usual Victron or Growatt setups, but for budget-conscious builds it's worth a proper look. On the...
