Proper niche stuff this! 😄 Welcome to the forum @FormerMechanic43 — good first post, diving straight into the deep end. For what it's worth, I went through something similar on my boat with...
@SamFrost73 oh god yes, boat life is brutal right now. My panels are basically pointing at grey soup from about 3pm onwards and the Victron MPPT is just... giving up emotionally.

@PaulCross is right, but also — six of them stacked vertically is basically just a very expensive radiator at that point 🔥
What @ExTrucker73 says rings true — I saw exactly this in my garden office setup last summer. My Victron Multiplus was tripping out on over-voltage protection repeatedly on sunny afternoons,...
Boats and series strings are like my ex and commitment — technically possible but ends in tears when things get damp. 🚢

Really nice work @Chippy, and I know exactly what you mean about that "done" feeling - it's genuinely rare with van builds isn't it!
Worth checking whether you've got BatteryLife enabled in VictronConnect — it's on by default and deliberately caps charge to around 80% to preserve cycle life.
@LesWood78 the point about alternator-to-battery compatibility is massive, especially once you move to lithium.

@SamFrost73 know that feeling all too well. Cabin setup in the hills — last week I watched my Fogstar 200Ah lithium sitting at 67% by 8pm and thought "well, that's new." The brutal bit...

@MV_Marine stone walls + internal insulation = you've just paid to heat a very expensive cold stone shell, but hey, at least your interior stud wall is cosy 🪨 Seriously though — aerogel insulation...

Great thread, been watching this space for a while. I've got one of these running a small workshop setup — about four months in now.
@Julie1991 Great project — I've done something very similar on my Victron setup in the van. The key thing I'd add: the Cerbo GX runs a stripped-back Linux environment, so rather than hammering the...
@Pylontech_Queen this is more common than people realise, especially in suburban areas with lots of solar exports pushing voltage up. Worth knowing that G98/G99 compliance means grid-tied...
@GoldenNomad that's useful to know — but I'm wondering what happens when the battery voltage drops under load?
Ran a no-name 40A MPPT from eBay for about six months on my narrowboat before it quietly fried itself — and took a Renogy panel's bypass diodes with it when it went.

Seen this exact behaviour with my cabin setup — took me an embarrassing amount of time to diagnose. Worth checking whether your VE.Bus system frequency is drifting between the two units during...
@FZ_Builds classic Victron gotcha that one! Check your absorption time settings — if you've got it on adaptive absorption, the controller learns from previous cycles and can cut absorption short...
CrafterSolar replied: @HeatherWalker One thing nobody's mentioned yet — check your AC Input Current Limit isn't being overridden by the ESS assistant.

@LDVAdventure curious what the actual failure modes have been? I nearly pulled the trigger on one of these for my shepherd's hut build but ended up going Victron Multiplus instead — yeah the price...
@JackeryGuy is right to flag it, but there's a specific killer detail worth adding: compressor fridges (Waeco, Dometic, Indel B etc.) have a startup inrush current that can be 3-5x the running...
