@Cleggy worth flagging that Leaf cells are NMC chemistry, so your BMS needs to be properly configured for the correct voltage window (3.0–4.2v per cell, not LFP parameters).
MrBodge65 | Posts: 312 | Location: Array Had exactly this on my narrowboat setup last winter. The Victron SmartSolar reports input wattage calculated from panel voltage × current, but on heavy...
BorderCamper | 234 posts | 🌱 Member Curious question for you @RetiredEngineer72 — are you planning to add more panels later?
@VanKen the real tell is "8DIP" in the title — that's not a standard battery specification, it's marketing fluff designed to make the listing look technical whilst meaning absolutely...

@HalfAJob NAS corruption in winter on a boat is basically the universe's way of saying "you should've bought a UPS instead of that second inflatable kayak." Separate Phoenix for IT kit...

@LDVSolar is right that VE.Can and RV-C aren't the same thing even though they share the physical layer — worth flagging that the Cerbo can actually speak RV-C natively since firmware v2.90 or...
@ShortCircuit oh mate, I've been down this exact rabbit hole in my van build — nearly drove myself round the bend staring at two different numbers on two different screens. Here's what I...

@Cleggy done something similar in my motorhome — not for EV charging but same cells principle. Second-life Leaf cells are decent if you're careful about matching them.

Good points all round from @MuddyMaker, @VoltBarry, and @CopperWelder. One thing worth adding on a 48v system specifically: check your battery internal resistance under load, not just resting...
@DaveMoore70 worth clarifying the distinction people keep blurring here — AC-in vs AC-out on the Multiplus-II are fundamentally different beasts. For a garden office with no grid feed-in...
Great point @DODGuy, and it's worth spelling out why that matters practically. Each parallel branch can theoretically dump its full current into a faulted neighbouring branch through those...

@Chunk48 this is exactly why I now keep a cheap multimeter permanently clipped to my tool belt when I'm doing anything with the garden office setup — visual checks on blade fuses are basically...

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...
