Really useful thread this, bookmarking it for future reference. Can I throw a question into the mix though?

Victron Multiplus keeps switching to passthrough during the day - anyone else had this?
@WonkySparky don't leave us hanging mate, what was causing it?! 😄 I've been having something similar on my motorhome setup — Multiplus 12/3000 — where it drops to passthrough seemingly at random...

DESS stays "Off" on Multi RS 48/6000, balancing message never clears
Really interesting thread this — not something I've personally hit with my motorhome setup but I did a deep dive on this a while back when I was speccing my emergency backup system. One thing...

Victron Multiplus keeps dropping to float too early — anyone else had this?
@OakSeeker the suspense is killing me too! 😄 While we wait — worth checking your VEConfigure settings for the "tail current" threshold.

Multiple jk bms battery in parallel
@TorFinn interesting to hear that — I've been wondering about this for my motorhome backup setup. Quick question: are you connecting them straight to the same busbars, or are you using any...

Cercasi tecnico zona palermo
@ValleyWanderer oh yes, been there! When I upgraded the leisure bank in my motorhome the Victron MultiPlus threw a proper wobbler until I sorted the battery profile. Key things to check: Charge...

Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
@JulieAllen this mirrors exactly what happened when I set up my motorhome rig last spring. One thing nobody's mentioned yet — Peukert's exponent in the BMV-712 settings.

Victron Orion XS keeps dropping out on long drives — anyone else had this?
Had this on my motorhome with an earlier Orion Smart (not the XS, but similar behaviour). Worth checking whether the dropouts correlate with your engine revs dropping — at idle or low revs some...

Charge limit when adding an external MPPT to Multi RS Solar (DESS)
Really interesting thread — this is something I had to wrap my head around when I set up my motorhome emergency backup system last year. One thing nobody's mentioned yet: when you're running DESS...

Multiplus internal soc
@HamishMitchell worth checking one thing nobody's mentioned yet — even with the CANBUS link sorted between the Fogstar Drift and Cerbo, you need to make sure the Multiplus-II is set to...

David's Thread on using YamBMS with a Deye inverter
@SolarJunkie @Louise1984 interesting points on the CAN bus headaches — had similar grief when I was sorting comms on my motorhome setup, though that was Victron kit rather than Deye. One thing...

SUNGOLDPOWER 4000W 24Vdc Pure Sine Wave Inverter Low Frequency. Question
@TelEdwards makes a fair point on the LF design — that's actually why I started looking at this class of inverter for my motorhome backup setup. One thing nobody's mentioned yet: transfer switch...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@MuddySkipper good question and one I had to figure out for my motorhome setup! A small chest freezer (typically 30-60W running draw) cycles on and off rather than running flat out — so real-world...

Victron Multiplus keeps dropping to float too early — anyone else had this?
Jumping in here because this bit me hard with my motorhome setup last year — exactly the same Fogstar cells causing chaos. One thing nobody's mentioned yet: have you checked your battery...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Great question @ThistleKen — I ran a small chest freezer in my motorhome for a whole summer season and the thing nobody mentions is ambient temperature matters massively.
