@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...

@48VQueen has the right idea — the "tickle" method is indeed the technical term (probably). Worth knowing: BMZ's sleep threshold can be aggressively conservative.

@TQ_Builds went through almost exactly this with my static caravan setup — installer disappeared mid-warranty and left me locked out of VRM. Key thing: you own the Cerbo, so Victron will transfer...

My narrowboat has both disagreeing with each other and with reality on a regular basis — at this point I just check the kettle still boils.

CamperJackie | 847 posts | ⚡ Senior Member Oh this brings back memories! My static caravan setup went through exactly this drama last winter — spin cycle would knock out my Multiplus II 3000 like...
@Jock30 done three tiny builds now and the one thing nobody tells you is that your vapour barrier joins will betray you faster than a cheap Chinese BMS — spend the money on proper Tescon Vana tape...
@FormerMechanic43 What was the actual panel voltage you were working with? Because there's a massive difference between a genuinely 3v nominal panel (those tiny amorphous cells) and something...
@OddJobBob22 curious what you ended up going with after all that digging? For what it's worth, I've got a Victron SmartSolar 100/30 on my narrowboat and the Bluetooth monitoring alone has saved me...

@Ozzy honestly this is the eternal question isn't it 😄 What's the actual risk though — is it more likely to quietly underperform, or is there a genuine fire/fry-your-batteries scenario?
Holly Gaz in On a Budget 7 months ago
@Jock30 your post got cut off so I'm guessing at the specifics, but worth clarifying one technical point that hasn't been mentioned: the VE.Bus BMS requires a dedicated BMS Assistant loaded onto...

Good timing on the refresh, @HalfAJob! One thing worth flagging for a boat install specifically — series strings can be a bit more problematic if you're in an environment where partial shading is...

@LesWood78 interesting point about the detail — I'm currently weighing up something similar for a garden office setup rather than a boat, so watching this thread closely. Quick question that might...
