@MarshSoul one thing worth mentioning alongside what @IanPearce56 said about cold voltage spikes — check your MPPT's input voltage log if Victron Connect allows it.

Really useful thread this. @WillowGazer raises a good point about the alternator — worth adding that fitting a proper DC-DC charger (B2B) between your alternator and the lithium is the sensible...

I've got a 400W panel array (2x200W Renogy monos) wired in series feeding into an Epever Tracer 4210AN, charging a 200Ah AGM bank. Summer was brilliant — regularly seeing 25-30A on a decent day.

Ha, @ForestDaz makes a fair point there @Keith1981 — the 2x120V is very much the wrong side of the pond!

Just to add a practical angle here — it's worth keeping an eye on your battery temperature as well as the panels.

Hey @MistyNomad, snap! Running virtually the same setup here — EVE 280Ah cells in a 24v configuration with a JBD BMS.

Really interesting thread this. @DazHenderson77 your "expensive bouncer" analogy is spot on 😄 One thing worth adding — I label mine clearly with a bit of bright orange tape and a written...

MistyMaker | 847 posts @Lefty31 Almost identical setup here! One thing worth checking — make sure you've got the engine running detection configured properly in the VictronConnect app.

Cheers for the replies, lads. Worth checking a few practical things before you assume it's a dead loss though: Have you got the battery's CANbus configured properly?
