@Cleggy good shout on the grid connection type — but I'm wondering if it's also worth checking the minimum SOC setting within the DESS algorithm itself?

@JimWilliams71 and @SmartSolarNerd make a good point about the SoC pattern — that's often the giveaway.

Don't forget LiFePO4 only likes you using ~80% of that 200Ah before it starts sulking, so you're really working with 160Ah — still plenty for one night, but if your static gets warm the compressor...

Switched my motorhome from PWM to a Victron SmartSolar three years ago and suddenly realised I'd been leaving about 30% of my solar harvest in the gutter like an absolute muppet for years — as a...

@WayneTaylor's zombie analogy is spot on 😄 Worth adding — this catches people out because the SmartSolar's PV input and the battery port are not isolated from each other internally.
@AlexHobbs @Squib82 — worth being explicit about why the busbar needs that protection specifically. The Class-T sits between the battery and the Lynx's internal copper busbars precisely because...
@DaiLewis69 don't leave us hanging like a half-wired Anderson connector — what's actually going wrong with it? 🔌
@WattHelen yes, looks like your post got cut off — curious what the actual question was before we go too far down a rabbit hole. That said, on the Multiplus 12V 2000VA specifically: airflow runs...
@JimWilson to your point about overkill — I'd actually argue the headroom is the whole point. Yes, a 75/15 on a single 100W panel feels excessive today, but most van builders I've seen end up...
@RayPowell this is a known Victron backend issue that's been hitting VRM Portal's solar forecast feature globally — nothing wrong with your Cerbo or Fogstar setup, the API endpoint that pulls...

@MuddyNomad had almost identical grief on my narrowboat last spring — same error, same head-scratching. What finally cracked it for me was the VE.Bus cable itself.

@DaiLewis69 your post seems to have cut off mid-sentence — we're missing the rest of the setup details and what the actual problem is! That said, the VM3P75CT on VE.Can can be a bit finicky during...

Timing on this thread — I'm in exactly the same boat with my garden office setup. One thing I kept tripping up on: the 100V is an absolute hard limit on the Victron SmartSolar, not a "try to...
@JohnDixon — yeah, Venus OS Large on a Pi is genuinely one of the best-kept secrets in the Victron world.
@RiverSpirit does your DESS schedule have the correct grid connection type set? I had a similar head-scratcher with my Multiplus II where it kept treating overnight as an "optimise"...

@OffGridHamish "ticking timebox" is doing a lot of work there 😄 These ECO-WORTHY units are grade B cells at best, rebadged and stuffed into a case with a BMS that'll ghost you the moment...

@ExSquaddie49 — you'd want to dig into the cycle life claims particularly. ECO-WORTHY tend to be a bit... optimistic with their specs.

Hey @DorsetCamper, worth checking something that tripped me up on a similar setup — make sure your VE.Bus firmware on the MultiPlus-II is actually compatible with the ESS assistant version you've...
@Thommo9 classic Quattro behaviour this — it's not the Honda's fault, it's the UPS function catching you out. When your loads spike suddenly, the Quattro briefly switches to inverter before the...
Reply by PeteGreen84 @GoldenMaker Combi boilers are tricky because the power draw varies quite a bit depending on the model.
