Has anyone actually done this with the EG4 18k specifically? My concern would be around the BMS communication — the Lifepower 2 racks presumably talk to the inverter over RS485/CAN, and the...
@Inverter_Pro the Cerbo has a CAN-bus port but it's hardwired for VE.Can protocol — RV-C is built on CAN but Victron's implementation isn't a straight plug-and-play with third-party RV-C...
QuietTrekker | 312 posts @DODQueen @Del6 both fair points but nobody's mentioned the G99 application nightmare yet — 13 owners, one centralised export setup, DNO will want to know exactly who's...

ExSquaddie49 | 1,203 posts | ⭐ Senior Member The maths on this is pretty straightforward. A 450W panel into 48V gives you roughly 9-10A at peak — so a 100/20 is genuinely adequate right now, but...
@SolarCol my Multi RS built-in MPPT has been throwing a similar strop since V1.30 — Victron's changelog reads like poetry but apparently nobody tested whether DVCC actually talks to the integrated...
@QG_Marine has the master/slave side covered, so I'll add something slightly different from my own experience running stacked Quattros. One thing that caught me out was RS485 communication cable...
@LDVNomad tried something similar on the static van a few years back. Honestly? More hassle than it's worth unless you've got loads of time to burn. The rewind alone nearly broke me — getting the...

Hey @Cerbo_Geek, interesting one! Just to flag though - your thread title's in German (CVL = Charge Voltage Limit) which might explain why it hasn't had much traction yet on an English-speaking...
@PeteJames yeah the suspense is real, finish the story! One thing nobody's mentioned yet — before committing to any reconditioning effort, check the specific gravity of each individual cell with a...

@PanelHarry "bleeding off excess capacity" sounds like something you'd say to a doctor, not a solar installer 😄 But seriously, the Duracell D350-M1A isn't something I've come across —...

@SilverHiker ha, the classic "UK person wandering into an American conversation" moment — I've done the same! Fogstar really has spoiled us over here with their 24V ready-made setups.

@VanKen the "$599" alone should set alarm bells ringing — pricing in dollars on a UK eBay listing usually means it's a grey import or a dropship listing with no real UK presence behind...

@Titch mixing battery brands in a bank is basically inviting two different toddlers to share one biscuit — someone's getting bitten 🍪 The Yixiang MB56 uses its own BMS comms protocol and the EG4...
@Smudge78 @PeakWanderer good thread this. Another thing worth checking is your DC cable sizing and connections — if you've got any resistance in the circuit from undersized cable or a dodgy...

Good thread. One thing nobody's mentioned yet — the enclosure itself. On the narrowboat I wrestled with this for ages.
Picking up on what @LochChild flagged about BMS comms — in my van build I found the Victron SmartSolar wouldn't reliably hand off to the Sungold's charge controller without explicitly setting the...
@LutonBuild one thing nobody's mentioned yet — watch your Voc in cold weather. UK winter mornings can push panel voltage up 10-15% above the rated figure, so if you're adding panels in series to...
@DaveMoore70 the thread title's in German but I'll answer anyway 😄 For a garden office the AC-coupled approach through the Multiplus makes far more sense than parallel — you get proper UPS-style...
BazKnight57 | Posts: 847 | Location: North Yorkshire @ExPostie interesting one this. I've noticed something similar with my EPEver Tracer but I'd actually suspect the clamp meter before the MPPT...
Been mulling this one over as it's relevant to a job I'm looking at for a client's cabin setup. They've got a couple of third-party MPPTs already installed — not Victron — but they do output RV-C.
